Clinical question: Is it safe to adopt a standardized approach to direct oral anticoagulant (DOAC) interruption for patients with atrial fibrillation (AFib) who are undergoing elective surgeries/procedures?

The primary clinical outcomes were major bleeding and arterial thromboembolism. Authors determined safety by comparing to expected outcome rates derived from research on perioperative warfarin management.

They found that all three drugs were associated with acceptable rates of arterial thromboembolism (apixaban 0.2%, dabigatran 0.6%, rivaroxaban 0.4%). The rates of major bleeding observed with each drug (apixaban 0.6% low-risk procedures, 3% high-risk procedures; dabigatran 0.9% both low- and high-risk procedures; and rivaroxaban 1.3% low-risk procedures, 3% high-risk procedures) were similar to those in the BRIDGE trial (patients on warfarin who were not bridged perioperatively). However, it must still be noted that only dabigatran met the authors’ predetermined definition of safety for major bleeding.

Limitations include the lack of true control rates for major bleeding and stroke, the relatively low mean CHADS2-Va2Sc of 3.3-3.5, and that greater than 95% of patients were white.

Bottom line: For patients with moderate-risk atrial fibrillation, a standardized approach to DOAC interruption in the perioperative period that omits bridging along with coagulation function testing appears safe in this preliminary study.

Intraoperative injection of calcium chloride into the four major atrial ganglionated plexi (GPs) reduced the incidence of early postoperative atrial fibrillation (POAF) in patients undergoing off-pump coronary artery bypass grafting (CABG) surgery, in a proof-of-concept study.

“[We] hypothesized that injecting [calcium chloride] into the major atrial GPs during isolated CABG can reduce the incidence of POAF by calcium-induced autonomic neurotoxicity,” wrote Huishan Wang, MD, of the General Hospital of Northern Theater Command in Shenyang, China, and colleagues. Their report was published in the Journal of the American College of Cardiology.

The single-center, sham-controlled, proof-of-concept study included 200 patients without a history of AF undergoing isolated, off-pump CABG surgery. Participants were randomized (1:1) to receive an injection of either 5% calcium chloride or 0.9% sodium chloride into the four major GPs during CABG.

Post surgery, patients were monitored for the occurrence of POAF using routine 12-lead ECG and 7-day continuous telemetry and Holter monitoring. The primary endpoint was the incidence of POAF lasting 30 seconds or longer through 7 days. Various secondary outcomes, including POAF burden and length of hospitalization, were also measured.

After analysis, the researchers found that 15 patients in the calcium chloride arm and 36 patients in the sodium chloride arm developed POAF during the first 7 days post CABG, corresponding to a POAF hazard reduction of 63% (hazard ratio, 0.37; 95% confidence interval, 0.21-0.64; P = .001) with no significant adverse effects observed among study patients.

The calcium chloride injection also resulted in reduced AF burden and lower rates of amiodarone and esmolol use to treat POAF; however, there was no difference in the length of hospitalization between the two groups. The incidences of nonsustained atrial tachyarrhythmia (less than 30 seconds) and atrial couplets were also significantly reduced in the calcium chloride group.

“We selected the 4 major atrial GPs as our targets because [of] their role in the initiation and maintenance of AF is more established than other cardiac neural plexi,” the researchers explained. “Interruption of the atrial neural network by Ca-mediated GP neurotoxicity may underlie the therapeutic effects.”
 

Is ‘nuisance’ arrhythmia worth targeting?

In an editorial accompanying the report, John H. Alexander, MD, MHS, wrote that intraoperative calcium chloride atrial ganglionic ablation can now be considered as an effective intervention to prevent POAF in patients undergoing cardiac surgery. “These investigators should be congratulated for studying post-operative atrial fibrillation in cardiac surgery,” he stated.

“However, this trial has two significant limitations. Firstly, it was conducted in a single center in a very homogeneous population; secondly, POAF, in and of itself, is largely a nuisance arrhythmia and hardly worth preventing, but is associated with a higher risk of other adverse outcomes,” Dr. Alexander, professor of medicine at Duke University, Durham, N.C., said in an interview.

“The unanswered question is whether preventing perioperative AF will prevent stroke, heart failure, and death,” he further explained. “Answering these questions would require a larger trial (or trials) with longer term (months to years) follow-up.”

Dr. Wang and colleagues acknowledged that the current study was underpowered for some secondary outcomes, such as length of hospitalization. They explained that a large sample size is needed to detect a difference in length of hospitalization, as well as other outcomes.

“Further studies are needed to confirm the safety and efficacy of calcium-induced atrial autonomic denervation in patients undergoing on-pump CABG and surgery for valvular heart disease,” they concluded.

The study was funded by the Provincial Key R & D Program in China. One author reported holding a U.S. patent related to the study. The remaining authors had no relevant relationships to disclose.

What is Lean and how can it help us?

The ‘Toyota Production System’-based philosophy has 14 core principles that help eliminate waste in systems in pursuit of efficiency. These principles are the “Toyota Way.” They center around two pillars: continuous improvement and respect for people. The cornerstone of this management methodology is based on efficient processes, developing employees to add value to the organization and continuous improvement through problem-solving and organizational learning.

Lean is often implemented with Six Sigma methodology. Six Sigma has its origins in Motorola. While Lean cuts waste in our systems to provide value, Six Sigma uses DMAIC (Define, Measure, Analyze, Improve, Control) to reduce variation in our processes. When done in its entirety, Lean Six Sigma methodology adds value by increasing efficiency, reducing cost, and improving our everyday work.

Statistical principles suggest that 80% of consequences comes from 20% of causes. Lean methodology and tools allow us to systematically identify root causes for the problems we face and help narrow it down to the ‘vital few.’ In other words, fixing these would give us the most bang for our buck. As hospitalists, we are able to do this better than most because we work in these hospital processes everyday – we truly know the strengths and weaknesses of our systems.

As a hospitalist, I would love for the process of seeing patients in hospitals to be more efficient, less variable, and be more cost-effective for my institution. By eliminating the time wasted performing unnecessary and redundant tasks in my everyday work, I can reallocate that time to patient care – the very reason I chose a career in medicine.
 

We, the people

There are two common rebuttals I hear for adopting Lean Six Sigma methodology in health care. A frequent misconception is that Lean is all about reducing staff or time with patients. The second is that manufacturing methodologies do not work for a service profession. For instance, an article published on Reuters Events (www.reutersevents.com/supplychain/supply-chain/end-just-time) talks about Lean JIT (Just In Time) inventory as a culprit for creating a supply chain deficit during COVID-19. It is not entirely without merit. However, if done the correct way, Lean is all about involving the frontline worker to create a workflow that would work best for them.

Reducing the waste in our processes and empowering our frontline doctors to be creative in finding solutions naturally leads to cost reduction. The cornerstone of Lean is creating a continuously learning organization and putting your employees at the forefront. I think it is important that Lean principles be utilized within health care – but we cannot push to fix every problem in our systems to perfection at a significant expense to the physician and other health care staff.
 

Why HM can benefit from Lean

There is no hard and fast rule about the way health care should adopt Lean thinking. It is a way of thinking that aims to balance purpose, people, and process – extremes of inventory management may not be necessary to be successful in health care. Lean tools alone would not create results. John Shook, chairman of Lean Global Network, has said that the social side of Lean needs to be in balance with the technical side. In other words, rigidity and efficiency is good, but so is encouraging creativity and flexibility in thinking within the workforce.

In the crisis created by the novel coronavirus, many hospitals in New York state, including my own, turned to Lean to respond quickly and effectively to the challenges. Lean principles helped them problem-solve and develop strategies to both recover from the pandemic surge and adapt to future problems that could occur. Geographic clustering of patients, PPE supply, OR shut down and ramp up, emergency management offices at the peak of the pandemic, telehealth streamlining, and post-COVID-19 care planning are some areas where the application of Lean resulted in successful responses to the challenges that 2020 brought to our work.

As Warren Bennis said, ‘The manager accepts the status quo; the leader challenges it.’ As hospitalists, we can lead the way our hospitals provide care. Lean is not just a way for hospitals to cut costs (although it helps quite a bit there). Its processes and philosophies could enable hospitalists to maximize potential, efficiency, quality of care, and allow for a balanced work environment. When applied in a manner that focuses on continuous improvement (and is cognizant of its limitations), it has the potential to increase the capability of our service lines and streamline our processes and workday for greater efficiency. As a specialty, we stand to benefit by taking the lead role in choosing how best to improve how we work. We should think outside the box. What better time to do this than now?

Federal health officials are urging states to vaccinate all Americans over age 65 and those aged 16-64 who have a documented underlying health condition that makes them more vulnerable to COVID-19.

U.S. Department of Health and Human Services (HHS) Secretary Alex Azar and Centers for Disease Control and Prevention Director Robert Redfield, MD, made the recommendation in a briefing with reporters on Jan. 12, saying that the current vaccine supply was sufficient to meet demand for the next phase of immunization as recommended by the CDC’s Advisory Committee on Immunization Practices.

“We are ready for a transition that we outlined last September in the playbook we sent to states,” Mr. Azar said. Both he and U.S. Army General Gustave F. Perna, chief operations officer for Operation Warp Speed, said that confidence in the distribution system had led to the decision to urge wider access.

The federal government will also increase the number of sites eligible to receive vaccine – including some 13,000 federally qualified community health centers – and will not keep doses in reserve as insurance against issues that might prevent people from receiving a second dose on a timely basis. 

“We don’t need to hold back reserve doses,” Mr. Azar said, noting that if there were any “glitches in production” the federal government would move to fulfill obligations for second doses first and delay initial doses.
 

Azar: Use it or lose it

In a move that is sure to generate pushback, Mr. Azar said that states that don’t quickly administer vaccines will receive fewer doses in the future. That policy will not go into effect until later in February, which leaves open the possibility that it could be reversed by the incoming Biden administration.

“We have too much vaccine sitting in freezers at hospitals with hospitals not using it,” said Mr. Azar, who also blamed the slow administration process on a reporting lag and states being what he called “overly prescriptive” in who has been eligible to receive a shot.

“I would rather have people working to get appointments to get vaccinated than having vaccine going to waste sitting in freezers,” he told reporters.

Mr. Azar had already been pushing for broader vaccination, telling states to do so in an Operation Warp Speed briefing on Jan. 6. At that briefing, he also said that the federal government would be stepping up vaccination through an “early launch” of a federal partnership with 19 pharmacy chains, which will let states allocate vaccines directly to some 40,000 pharmacy sites.

Gen. Perna said during the Jan. 12 briefing that the aim is to further expand that to some 70,000 locations total.

The CDC reported that as of Jan. 11 some 25.4 million doses have been distributed, with 8.9 million administered. An additional 4.2 million doses were distributed to long-term care facilities, and 937,000 residents and staff have received a dose.
 

“Pace of administration”

Alaska, Connecticut, North Dakota, South Dakota, the District of Columbia, West Virginia, and the Northern Mariana Islands have administered the most vaccines per capita, according to the CDC. But even these locations have immunized only 4%-5% of their populations, the New York Times reports. At the bottom: Alabama, Arizona, Arkansas, Georgia, Mississippi, and South Carolina.

The federal government can encourage but not require states to move on to new phases of vaccination.

“States ultimately determine how they will proceed with vaccination,” said Marcus Plescia, MD, MPH, chief medical officer for the Association of State and Territorial Health Officials. “Most will be cautious about assuring there are doses for those needing a second dose,” he said in an interview.

Dr. Plescia said that ensuring a second dose is available is especially important for health care workers “who need to be confident that they are protected and not inadvertently transmitting the disease themselves.”

He added that “once we reach a steady state of supply and administration, the rate-limiting factor will be supply of vaccine.”

That supply could now be threatened if states don’t comply with a just-announced federal action that will change how doses are allocated.

Beginning in late February, vaccine allocations to states will be based on “the pace of administration reported by states,” and the size of the 65-and-older population, said Mr. Azar, who has previously criticized New York Governor Andrew Cuomo for fining hospitals that didn’t use up vaccine supply within a week.

“This new system gives states a strong incentive to ensure that all vaccinations are being promptly reported, which they currently are not,” he said.

Currently, allocations are based on a state’s or territory’s population.

Prepandemic, states were required to report vaccinations within 30 days. Since COVID-19 vaccines became available, the CDC has required reporting of shots within 72 hours.

Dr. Redfield said the requirement has caused some difficulty, and that the CDC is investigating why some states have reported using only 15% of doses while others have used 80%.

States have been scrambling to ramp up vaccinations.

Just ahead of the federal briefing, Gov. Cuomo tweeted that New York would be opening up vaccinations to anyone older than 65.

The Associated Press is reporting that some states have started mass vaccination sites.

Arizona has begun operating a 24/7 appointment-only vaccination program at State Farm Stadium outside of Phoenix, with the aim of immunizing 6,000 people each day, according to local radio station KJZZ.

California and Florida have also taken steps to use stadiums, while Michigan, New Jersey, New York, and Texas will use convention centers and fairgrounds, Axios has reported.

In Florida, Palm Beach County Health Director Alina Alonso, MD, told county commissioners on Jan. 12 that there isn’t enough vaccine to meet demand, WPTV reported. “We need to realize that there’s a shortage of vaccine. So it’s not the plan, it’s not our ability to do it. It’s simply supply and demand at this point,” Dr. Alonso said, according to the TV station report.

Federal health officials are urging states to vaccinate all Americans over age 65 and those aged 16-64 who have a documented underlying health condition that makes them more vulnerable to COVID-19.

U.S. Department of Health and Human Services (HHS) Secretary Alex Azar and Centers for Disease Control and Prevention Director Robert Redfield, MD, made the recommendation in a briefing with reporters on Jan. 12, saying that the current vaccine supply was sufficient to meet demand for the next phase of immunization as recommended by the CDC’s Advisory Committee on Immunization Practices.

“We are ready for a transition that we outlined last September in the playbook we sent to states,” Mr. Azar said. Both he and U.S. Army General Gustave F. Perna, chief operations officer for Operation Warp Speed, said that confidence in the distribution system had led to the decision to urge wider access.

The federal government will also increase the number of sites eligible to receive vaccine – including some 13,000 federally qualified community health centers – and will not keep doses in reserve as insurance against issues that might prevent people from receiving a second dose on a timely basis. 

“We don’t need to hold back reserve doses,” Mr. Azar said, noting that if there were any “glitches in production” the federal government would move to fulfill obligations for second doses first and delay initial doses.
 

Azar: Use it or lose it

In a move that is sure to generate pushback, Mr. Azar said that states that don’t quickly administer vaccines will receive fewer doses in the future. That policy will not go into effect until later in February, which leaves open the possibility that it could be reversed by the incoming Biden administration.

“We have too much vaccine sitting in freezers at hospitals with hospitals not using it,” said Mr. Azar, who also blamed the slow administration process on a reporting lag and states being what he called “overly prescriptive” in who has been eligible to receive a shot.

“I would rather have people working to get appointments to get vaccinated than having vaccine going to waste sitting in freezers,” he told reporters.

Mr. Azar had already been pushing for broader vaccination, telling states to do so in an Operation Warp Speed briefing on Jan. 6. At that briefing, he also said that the federal government would be stepping up vaccination through an “early launch” of a federal partnership with 19 pharmacy chains, which will let states allocate vaccines directly to some 40,000 pharmacy sites.

Gen. Perna said during the Jan. 12 briefing that the aim is to further expand that to some 70,000 locations total.

The CDC reported that as of Jan. 11 some 25.4 million doses have been distributed, with 8.9 million administered. An additional 4.2 million doses were distributed to long-term care facilities, and 937,000 residents and staff have received a dose.
 

“Pace of administration”

Alaska, Connecticut, North Dakota, South Dakota, the District of Columbia, West Virginia, and the Northern Mariana Islands have administered the most vaccines per capita, according to the CDC. But even these locations have immunized only 4%-5% of their populations, the New York Times reports. At the bottom: Alabama, Arizona, Arkansas, Georgia, Mississippi, and South Carolina.

The federal government can encourage but not require states to move on to new phases of vaccination.

“States ultimately determine how they will proceed with vaccination,” said Marcus Plescia, MD, MPH, chief medical officer for the Association of State and Territorial Health Officials. “Most will be cautious about assuring there are doses for those needing a second dose,” he said in an interview.

Dr. Plescia said that ensuring a second dose is available is especially important for health care workers “who need to be confident that they are protected and not inadvertently transmitting the disease themselves.”

He added that “once we reach a steady state of supply and administration, the rate-limiting factor will be supply of vaccine.”

That supply could now be threatened if states don’t comply with a just-announced federal action that will change how doses are allocated.

The United States has allocated more than 641,000 monoclonal antibody treatments for outpatients to ease pressure on strained hospitals, but officials from Operation Warp Speed report that more than half of that reserve sits unused as clinicians grapple with best practices.

There are space and personnel limitations in hospitals right now, Janet Woodcock, MD, therapeutics lead on Operation Warp Speed, acknowledges in an interview with this news organization. “Special areas and procedures must be set up.” And the operation is in the process of broadening availability beyond hospitals, she points out.

But for frontline clinicians, questions about treatment efficacy and the logistics of administering intravenous drugs to infectious outpatients loom large.

More than 50 monoclonal antibody products that target SARS-CoV-2 are now in development. The U.S. Food and Drug Administration has already issued Emergency Use Authorization (EUA) for two such drugs on the basis of phase 2 trial data – bamlanivimab, made by Eli Lilly, and a cocktail of casirivimab plus imdevimab, made by Regeneron – and another two-antibody cocktail from AstraZeneca, AZD7442, has started phase 3 clinical trials. The Regeneron combination was used to treat President Donald Trump when he contracted COVID-19 in October.

Monoclonal antibody drugs are based on the natural antibodies that the body uses to fight infections. They work by binding to a specific target and then blocking its action or flagging it for destruction by other parts of the immune system. Both bamlanivimab and the casirivimab plus imdevimab combination target the spike protein of the virus and stop it from attaching to and entering human cells.
 

Targeting the spike protein out of the hospital

The antibody drugs covered by EUAs do not cure COVID-19, but they have been shown to reduce hospitalizations and visits to the emergency department for patients at high risk for disease progression. They are approved to treat patients older than 12 years with mild to moderate COVID-19 who are at high risk of progressing to severe disease or hospitalization. They are not authorized for use in patients who have been hospitalized or who are on ventilators. The hope is that antibody drugs will reduce the number of severe cases of COVID-19 and ease pressure on overstretched hospitals.

Most COVID-19 patients are outpatients, so we need something to keep them from getting worse.

This is important because it targets the greatest need in COVID-19 therapeutics, says Rajesh Gandhi, MD, an infectious disease physician at Harvard Medical School in Boston, who is a member of two panels evaluating COVID-19 treatments: one for the Infectious Disease Society of America and the other for the National Institutes of Health. “Up to now, most of the focus has been on hospitalized patients,” he says, but “most COVID-19 patients are outpatients, so we need something to keep them from getting worse.”

Both panels have said that, despite the EUAs, more evidence is needed to be sure of the efficacy of the drugs and to determine which patients will benefit the most from them.

These aren’t the mature data from drug development that guideline groups are accustomed to working with, Dr. Woodcock points out. “But this is an emergency and the data taken as a whole are pretty convincing,” she says. “As I look at the totality of the evidence, monoclonal antibodies will have a big effect in keeping people out of the hospital and helping them recover faster.”

High-risk patients are eligible for treatment, especially those older than 65 years and those with comorbidities who are younger. Access to the drugs is increasing for clinicians who are able to infuse safely or work with a site that will.

In the Boston area, several hospitals, including Massachusetts General where Dr. Gandhi works, have set up infusion centers where newly diagnosed patients can get the antibody treatment if their doctor thinks it will benefit them. And Coram, a provider of at-home infusion therapy owned by the CVS pharmacy chain, is running a pilot program offering the Eli Lilly drug to people in seven cities – including Boston, Chicago, Los Angeles, and Tampa – and their surrounding communities with a physician referral.

Getting that referral could be tricky, however, for patients without a primary care physician or for those whose doctor isn’t already connected to one of the institutions providing the infusions. The hospitals are sending out communications on how patients and physicians can get the therapy, but Dr. Gandhi says that making information about access available should be a priority. The window for the effective treatment is small – the drugs appear to work best before patients begin to make their own antibodies, says Dr. Gandhi – so it’s vital that doctors act quickly if they have a patient who is eligible.

And rolling out the new therapies to patients around the world will be a major logistical undertaking.

The first hurdle will be making enough of them to go around. Case numbers are skyrocketing around the globe, and producing the drugs is a complex time- and labor-intensive process that requires specialized facilities. Antibodies are produced by cell lines in bioreactors, so a plant that churns out generic aspirin tablets can’t simply be converted into an antibody factory.

“These types of drugs are manufactured in a sterile injectables plant, which is different from a plant where oral solids are made,” says Kim Crabtree, senior director of pharma portfolio management for Henry Schein Medical, a medical supplies distributor. “Those are not as plentiful as a standard pill factory.”

The doses required are also relatively high – 1.2 g of each antibody in Regeneron’s cocktail – which will further strain production capacity. Leah Lipsich, PhD, vice president of strategic program direction at Regeneron, says the company is prepared for high demand and has been able to respond, thanks to its rapid development and manufacturing technology, known as VelociSuite, which allows it to rapidly scale-up from discovery to productions in weeks instead of months.

“We knew supply would be a huge problem for COVID-19, but because we had such confidence in our technology, we went immediately from research-scale to our largest-scale manufacturing,” she says. “We’ve been manufacturing our cocktail for months now.”

The company has also partnered with Roche, the biggest manufacturer and vendor of monoclonal antibodies in the world, to manufacture and supply the drugs. Once full manufacturing capacity is reached in 2021, the companies expect to produce at least 2 million doses a year.

Then there is the issue of getting the drugs from the factories to the places they will be used.

Antibodies are temperature sensitive and need to be refrigerated during transport and storage, so a cold-chain-compliant supply chain is required. Fortunately, they can be kept at standard refrigerator temperatures, ranging from 2° C to 8° C, rather than the ultra-low temperatures required by some COVID-19 vaccines.
 

Two million doses a year

Medical logistics companies have a lot of experience dealing with products like these and are well prepared to handle the new antibody drugs. “There are quite a few products like these on the market, and the supply chain is used to shipping them,” Ms. Crabtree says.

They will be shipped to distribution centers in refrigerated trucks, repacked into smaller lots that can sustain the correct temperature for 24 hours, and then sent to their final destination, often in something as simple as a Styrofoam cooler filled with dry ice.

The expected rise in demand shouldn’t be too much of an issue for distributors either, says Ms. Crabtree; they have built systems that can deal with short-term surges in volume. The annual flu vaccine, for example, involves shipping a lot of product in a very short time, usually from August to November. “The distribution system is used to seasonal variations and peaks in demand,” she says.

The next question is how the treatments will be administered. Although most patients who will receive monoclonal antibodies will be ambulatory and not hospitalized, the administration requires intravenous infusion. Hospitals, of course, have a lot of experience with intravenous drugs, but typically give them only to inpatients. Most other monoclonal antibody drugs – such as those for cancer and autoimmune disorders – are given in specialized suites in doctor’s offices or in stand-alone infusion clinics.

That means that the places best suited to treat COVID-19 patients with antibodies are those that regularly deal with people who are immunocompromised, and such patients should not be interacting with people who have an infectious disease. “How do we protect the staff and other patients?” Dr. Gandhi asks.
 

Protecting staff and other patients

This is not an insurmountable obstacle, he points out, but it is one that requires careful thought and planning to accommodate COVID-19 patients without unduly disrupting life-saving treatments for other patients. It might involve, for example, treating COVID-19 patients in sequestered parts of the clinic or at different times of day, with even greater attention paid to cleaning, he explains. “We now have many months of experience with infection control, so we know how to do this; it’s just a question of logistics.”

But even once all the details around manufacturing, transporting, and administering the drugs are sorted out, there is still the issue of how they will be distributed fairly and equitably.

Despite multiple companies working to produce an array of different antibody drugs, demand is still expected to exceed supply for many months. “With more than 200,000 new cases a day in the United States, there won’t be enough antibodies to treat all of the high-risk patients,” says Dr. Gandhi. “Most of us are worried that demand will far outstrip supply. People are talking about lotteries to determine who gets them.”

The Department of Health and Human Services will continue to distribute the drugs to states on the basis of their COVID-19 burdens, and the states will then decide how much to provide to each health care facility.

Although the HHS goal is to ensure that the drugs reach as many patients as possible, no matter where they live and regardless of their income, there are still concerns that larger facilities serving more affluent areas will end up being favored, if only because they are the ones best equipped to deal with the drugs right now.

“We are all aware that this has affected certain communities more, so we need to make sure that the drugs are used equitably and made available to the communities that were hardest hit,” says Dr. Gandhi. The ability to monitor drug distribution should be built into the rollout, so that institutions and governments will have some sense of whether they are being doled out evenly, he adds.

Equity in distribution will be an issue for the rest of the world as well. Currently, 80% of monoclonal antibodies are sold in Canada, Europe, and the United States; few, if any, are available in low- and middle-income countries. The treatments are expensive: the cost of producing one g of marketed monoclonal antibodies is between $95 and $200, which does not include the cost of R&D, packaging, shipping, or administration. The median price for antibody treatment not related to COVID-19 runs from $15,000 to $200,000 per year in the United States.

Regeneron’s Dr. Lipsich says that the company has not yet set a price for its antibody cocktail. The government paid $450 million for its 300,000 doses, but that price includes the costs of research, manufacturing, and distribution, so is not a useful indicator of the eventual per-dose price. “We’re not in a position to talk about how it will be priced yet, but we will do our best to make it affordable and accessible to all,” she says.

There are some projects underway to ensure that the drugs are made available in poorer countries. In April, the COVID-19 Therapeutics Accelerator – an initiative launched by the Bill & Melinda Gates Foundation, Wellcome, and Mastercard to speed-up the response to the global pandemic – reserved manufacturing capacity with Fujifilm Diosynth Biotechnologies in Denmark for future monoclonal antibody therapies that will supply low- and middle-income countries. In October, the initiative announced that Eli Lilly would use that reserved capacity to produce its antibody drug starting in April 2021.

In the meantime, Lilly will make some of its product manufactured in other facilities available to lower-income countries. To help keep costs down, the company’s collaborators have agreed to waive their royalties on antibodies distributed in low- and middle-income countries.

“Everyone is looking carefully at how the drugs are distributed to ensure all will get access,” said Dr. Lipsich.

The Department of Health and Human Services will continue to distribute the drugs to states on the basis of their COVID-19 burdens, and the states will then decide how much to provide to each health care facility.

Although the HHS goal is to ensure that the drugs reach as many patients as possible, no matter where they live and regardless of their income, there are still concerns that larger facilities serving more affluent areas will end up being favored, if only because they are the ones best equipped to deal with the drugs right now.

“We are all aware that this has affected certain communities more, so we need to make sure that the drugs are used equitably and made available to the communities that were hardest hit,” says Dr. Gandhi. The ability to monitor drug distribution should be built into the rollout, so that institutions and governments will have some sense of whether they are being doled out evenly, he adds.

Equity in distribution will be an issue for the rest of the world as well. Currently, 80% of monoclonal antibodies are sold in Canada, Europe, and the United States; few, if any, are available in low- and middle-income countries. The treatments are expensive: the cost of producing one g of marketed monoclonal antibodies is between $95 and $200, which does not include the cost of R&D, packaging, shipping, or administration. The median price for antibody treatment not related to COVID-19 runs from $15,000 to $200,000 per year in the United States.

Regeneron’s Dr. Lipsich says that the company has not yet set a price for its antibody cocktail. The government paid $450 million for its 300,000 doses, but that price includes the costs of research, manufacturing, and distribution, so is not a useful indicator of the eventual per-dose price. “We’re not in a position to talk about how it will be priced yet, but we will do our best to make it affordable and accessible to all,” she says.

There are some projects underway to ensure that the drugs are made available in poorer countries. In April, the COVID-19 Therapeutics Accelerator – an initiative launched by the Bill & Melinda Gates Foundation, Wellcome, and Mastercard to speed-up the response to the global pandemic – reserved manufacturing capacity with Fujifilm Diosynth Biotechnologies in Denmark for future monoclonal antibody therapies that will supply low- and middle-income countries. In October, the initiative announced that Eli Lilly would use that reserved capacity to produce its antibody drug starting in April 2021.

In the meantime, Lilly will make some of its product manufactured in other facilities available to lower-income countries. To help keep costs down, the company’s collaborators have agreed to waive their royalties on antibodies distributed in low- and middle-income countries.

“Everyone is looking carefully at how the drugs are distributed to ensure all will get access,” said Dr. Lipsich.

The United States has allocated more than 641,000 monoclonal antibody treatments for outpatients to ease pressure on strained hospitals, but officials from Operation Warp Speed report that more than half of that reserve sits unused as clinicians grapple with best practices.

There are space and personnel limitations in hospitals right now, Janet Woodcock, MD, therapeutics lead on Operation Warp Speed, acknowledges in an interview with this news organization. “Special areas and procedures must be set up.” And the operation is in the process of broadening availability beyond hospitals, she points out.

But for frontline clinicians, questions about treatment efficacy and the logistics of administering intravenous drugs to infectious outpatients loom large.

More than 50 monoclonal antibody products that target SARS-CoV-2 are now in development. The U.S. Food and Drug Administration has already issued Emergency Use Authorization (EUA) for two such drugs on the basis of phase 2 trial data – bamlanivimab, made by Eli Lilly, and a cocktail of casirivimab plus imdevimab, made by Regeneron – and another two-antibody cocktail from AstraZeneca, AZD7442, has started phase 3 clinical trials. The Regeneron combination was used to treat President Donald Trump when he contracted COVID-19 in October.

Monoclonal antibody drugs are based on the natural antibodies that the body uses to fight infections. They work by binding to a specific target and then blocking its action or flagging it for destruction by other parts of the immune system. Both bamlanivimab and the casirivimab plus imdevimab combination target the spike protein of the virus and stop it from attaching to and entering human cells.
 

Targeting the spike protein out of the hospital

The antibody drugs covered by EUAs do not cure COVID-19, but they have been shown to reduce hospitalizations and visits to the emergency department for patients at high risk for disease progression. They are approved to treat patients older than 12 years with mild to moderate COVID-19 who are at high risk of progressing to severe disease or hospitalization. They are not authorized for use in patients who have been hospitalized or who are on ventilators. The hope is that antibody drugs will reduce the number of severe cases of COVID-19 and ease pressure on overstretched hospitals.

Most COVID-19 patients are outpatients, so we need something to keep them from getting worse.

This is important because it targets the greatest need in COVID-19 therapeutics, says Rajesh Gandhi, MD, an infectious disease physician at Harvard Medical School in Boston, who is a member of two panels evaluating COVID-19 treatments: one for the Infectious Disease Society of America and the other for the National Institutes of Health. “Up to now, most of the focus has been on hospitalized patients,” he says, but “most COVID-19 patients are outpatients, so we need something to keep them from getting worse.”

Both panels have said that, despite the EUAs, more evidence is needed to be sure of the efficacy of the drugs and to determine which patients will benefit the most from them.

These aren’t the mature data from drug development that guideline groups are accustomed to working with, Dr. Woodcock points out. “But this is an emergency and the data taken as a whole are pretty convincing,” she says. “As I look at the totality of the evidence, monoclonal antibodies will have a big effect in keeping people out of the hospital and helping them recover faster.”

High-risk patients are eligible for treatment, especially those older than 65 years and those with comorbidities who are younger. Access to the drugs is increasing for clinicians who are able to infuse safely or work with a site that will.

In the Boston area, several hospitals, including Massachusetts General where Dr. Gandhi works, have set up infusion centers where newly diagnosed patients can get the antibody treatment if their doctor thinks it will benefit them. And Coram, a provider of at-home infusion therapy owned by the CVS pharmacy chain, is running a pilot program offering the Eli Lilly drug to people in seven cities – including Boston, Chicago, Los Angeles, and Tampa – and their surrounding communities with a physician referral.

Getting that referral could be tricky, however, for patients without a primary care physician or for those whose doctor isn’t already connected to one of the institutions providing the infusions. The hospitals are sending out communications on how patients and physicians can get the therapy, but Dr. Gandhi says that making information about access available should be a priority. The window for the effective treatment is small – the drugs appear to work best before patients begin to make their own antibodies, says Dr. Gandhi – so it’s vital that doctors act quickly if they have a patient who is eligible.

And rolling out the new therapies to patients around the world will be a major logistical undertaking.

The first hurdle will be making enough of them to go around. Case numbers are skyrocketing around the globe, and producing the drugs is a complex time- and labor-intensive process that requires specialized facilities. Antibodies are produced by cell lines in bioreactors, so a plant that churns out generic aspirin tablets can’t simply be converted into an antibody factory.

“These types of drugs are manufactured in a sterile injectables plant, which is different from a plant where oral solids are made,” says Kim Crabtree, senior director of pharma portfolio management for Henry Schein Medical, a medical supplies distributor. “Those are not as plentiful as a standard pill factory.”

The doses required are also relatively high – 1.2 g of each antibody in Regeneron’s cocktail – which will further strain production capacity. Leah Lipsich, PhD, vice president of strategic program direction at Regeneron, says the company is prepared for high demand and has been able to respond, thanks to its rapid development and manufacturing technology, known as VelociSuite, which allows it to rapidly scale-up from discovery to productions in weeks instead of months.

“We knew supply would be a huge problem for COVID-19, but because we had such confidence in our technology, we went immediately from research-scale to our largest-scale manufacturing,” she says. “We’ve been manufacturing our cocktail for months now.”

The company has also partnered with Roche, the biggest manufacturer and vendor of monoclonal antibodies in the world, to manufacture and supply the drugs. Once full manufacturing capacity is reached in 2021, the companies expect to produce at least 2 million doses a year.

Then there is the issue of getting the drugs from the factories to the places they will be used.

Antibodies are temperature sensitive and need to be refrigerated during transport and storage, so a cold-chain-compliant supply chain is required. Fortunately, they can be kept at standard refrigerator temperatures, ranging from 2° C to 8° C, rather than the ultra-low temperatures required by some COVID-19 vaccines.
 

Two million doses a year

Medical logistics companies have a lot of experience dealing with products like these and are well prepared to handle the new antibody drugs. “There are quite a few products like these on the market, and the supply chain is used to shipping them,” Ms. Crabtree says.

They will be shipped to distribution centers in refrigerated trucks, repacked into smaller lots that can sustain the correct temperature for 24 hours, and then sent to their final destination, often in something as simple as a Styrofoam cooler filled with dry ice.

The expected rise in demand shouldn’t be too much of an issue for distributors either, says Ms. Crabtree; they have built systems that can deal with short-term surges in volume. The annual flu vaccine, for example, involves shipping a lot of product in a very short time, usually from August to November. “The distribution system is used to seasonal variations and peaks in demand,” she says.

The next question is how the treatments will be administered. Although most patients who will receive monoclonal antibodies will be ambulatory and not hospitalized, the administration requires intravenous infusion. Hospitals, of course, have a lot of experience with intravenous drugs, but typically give them only to inpatients. Most other monoclonal antibody drugs – such as those for cancer and autoimmune disorders – are given in specialized suites in doctor’s offices or in stand-alone infusion clinics.

That means that the places best suited to treat COVID-19 patients with antibodies are those that regularly deal with people who are immunocompromised, and such patients should not be interacting with people who have an infectious disease. “How do we protect the staff and other patients?” Dr. Gandhi asks.
 

Protecting staff and other patients

This is not an insurmountable obstacle, he points out, but it is one that requires careful thought and planning to accommodate COVID-19 patients without unduly disrupting life-saving treatments for other patients. It might involve, for example, treating COVID-19 patients in sequestered parts of the clinic or at different times of day, with even greater attention paid to cleaning, he explains. “We now have many months of experience with infection control, so we know how to do this; it’s just a question of logistics.”

But even once all the details around manufacturing, transporting, and administering the drugs are sorted out, there is still the issue of how they will be distributed fairly and equitably.

Despite multiple companies working to produce an array of different antibody drugs, demand is still expected to exceed supply for many months. “With more than 200,000 new cases a day in the United States, there won’t be enough antibodies to treat all of the high-risk patients,” says Dr. Gandhi. “Most of us are worried that demand will far outstrip supply. People are talking about lotteries to determine who gets them.”

The United States added over 171,000 new COVID-19 cases in children during the week ending Jan. 7, but that figure is lower than 3 of the previous 4 weeks, according to a report from the American Academy of Pediatrics and the Children’s Hospital Association.

Despite an increase compared with the week ending Dec. 31, the most recent weekly total is down from the high of 182,000 cases reported for the week ending Dec. 17, based on data collected from the health department websites of 49 states (excluding New York), the District of Columbia, New York City, Puerto Rico, and Guam.

Those jurisdictions have recorded a total of almost 2.3 million COVID-19 cases in children since the beginning of the pandemic, which amounts to 12.5% of reported cases among all ages. The 171,000 child cases for the most recent week represented 12.9% of the more than 1.3 million cases nationwide, the AAP and CHA said in their latest weekly update.

The United States now has a rate of 3,055 COVID-19 cases per 100,000 children in the population, the report shows, with 31 states above that figure and 14 states reporting rates above 4,500 per 100,000 children.

Severe illness, however, continues to be rare among children. So far, children represent 1.8% of all hospitalizations in the jurisdictions reporting such data (24 states and New York City), and just 0.9% of infected children have been hospitalized. There have been 188 deaths among children in 42 states and New York City, which makes up just 0.06% of the total for all ages in those jurisdictions, the AAP and CHA reported.

There are 13 states that have reported no coronavirus-related deaths in children, while Texas (34), New York City (21), Arizona (17), and Illinois (11) are the only jurisdictions with 10 or more. Nevada has the highest proportion of child deaths to all deaths at 0.2%, with Arizona and Nebraska next at 0.18%, according to the AAP/CHA report.

Background: Corticosteroids in the setting of an acute exacerbation of improve COPD symptoms but do not affect the decline in lung function, rate of repeat exacerbations after a month, or mortality. There is concern regarding the cumulative adverse effects over time. Limited prior research suggests that a patient’s blood eosinophil count may be useful for determining the necessity of steroids for treatment of exacerbation.

The primary outcome of days alive and out of the hospital within 14 days after recruitment was similar between groups (9 days; P = .34), along with the secondary outcome of treatment failure (26%; P = .90). Importantly, the cumulative steroid dose in the eosinophilia-guided group was lower than that of the control group at days 5, 30, and 90 (P less than or equal to .0002). Additionally, the control arm had worsening of baseline diabetes within 30 days and was more likely to require antibiotics for infections within 90 days.

Although not statistically significant, a trend was noted toward increased readmission for COPD exacerbations or death at 30 days in the eosinophilia-guided group (25% vs. 17% of control; P = .10). Future work will need to further study this trend.

Bottom line: Eosinophilia-guided treatment of COPD exacerbations reduced the cumulative exposure of steroid therapy, thereby decreasing side effects, although further study of safety profile is warranted.

An update of the U.S. Preventive Services Task Force recommendation for hepatitis B screening shows little change from the 2014 version, but some wonder if it should have gone farther than a risk-based approach.

The recommendation, which was published in JAMA, reinforces that screening should be conducted among adolescents and adults who are at increased risk of hepatitis B virus (HBV) infection. The USPSTF named six categories of individuals at increased risk of infection: Persons born in countries with a 2% or higher prevalence of hepatitis B, such as Asia, Africa, the Pacific Islands, and some areas of South America; unvaccinated individuals born in the United States to parents from regions with a very high prevalence of HBV (≥8%); HIV-positive individuals; those who use injected drugs; men who have sex with men; and people who live with people who have HBV or who have HBV-infected sexual partners. It also recommended that pregnant women be screened for HBV infection during their first prenatal visit.

“I view the updated recommendations as an important document because it validates the importance of HBV screening, and the Grade B recommendation supports mandated insurance coverage for the screening test,” said Joseph Lim, MD, who is a professor of medicine at Yale University and director of the Yale Viral Hepatitis Program, both in New Haven, Conn.

Still, the recommendation could have gone further. Notably absent from the USPSTF document, yet featured in recommendations from the Centers for Disease Control and Prevention and the American Association for the Study of Liver Disease, are patients who have diabetes, are on immunosuppressive therapy, or have elevated liver enzymes or liver disease. Furthermore, a single-center study found that, among physicians administering immunosuppressive therapy, a setting in which HBV reactivation is a concern, there were low rates of screening for HBV infection, and the physicians did not reliably identify high-risk patients.

“This may also be viewed as a lost opportunity. Evidence suggests that risk factor–based screening is ineffective for the identification of chronic conditions such as hepatitis B. Risk factor–based screening is difficult to implement across health systems and exacerbates the burden on community-based organizations that are motivated to address viral hepatitis. It may further exacerbate labeling, stigma, and discrimination within already marginalized communities that are deemed to be at high risk,” said Dr. Lim.

A similar view was expressed by Avegail Flores, MD, medical director of liver transplantation at the Michael E. DeBakey Veterans Affairs Medical Center and assistant professor of medicine at Baylor College of Medicine, both in Houston. “This is a good launching point, and with further evidence provided, hopefully it will also bring in a broader conversation about other persons who are at risk but not included in these criteria.” Neither Dr. Lim nor Dr. Flores were involved in the study.

She noted that resistance to universal screening may be caused by the relatively low prevalence of hepatitis B infection in the United States. However, the CDC estimates that only about 61% of people infected with HBV are aware of it. “I don’t think we have done a good job screening those who are at risk,” said Dr. Flores.

Universal screening could help, but would have a low yield. Dr. Flores suggested expansion into other at-risk groups, such as Baby Boomers. With respect to other risk groups that could be stigmatized or discriminated against, Dr. Flores recalled her medical school days when some students went directly into underserved communities to provide information and screening services. “We have to think of creative ways of how to reach out to people, not just relying on the usual physician-patient relationship.”

The issue is especially timely because the World Health Organization has declared a target to reduce new hepatitis B infections by 90% by 2030, and that will require addressing gaps in diagnosis. “That’s why these recommendations are so consequential. We are at a critical juncture in terms of global hepatitis elimination efforts. There is a time sensitive need to have multistakeholder engagement in ensuring that all aspects of the care cascade are addressed. Because of the central role of screening and diagnosis, it’s of critical importance that organizations such as USPSTF are in alignment with other organizations that have already issued clear guidance on who should be screened. It is (my) hope that further examination of the evidence-base will further support broadening USPSTF guidance to include a larger group of at-risk individuals, or ideally a universal screening strategy,” said Dr. Lim.

The recommendation’s authors received travel reimbursement for their involvement, and one author reported receiving grants and personal fees from Healthwise. Dr. Flores has no relevant financial disclosures. Dr. Lim is a member of the American Association for the Study of Liver Disease’s Viral Hepatitis Elimination Task Force.

An update of the U.S. Preventive Services Task Force recommendation for hepatitis B screening shows little change from the 2014 version, but some wonder if it should have gone farther than a risk-based approach.

The recommendation, which was published in JAMA, reinforces that screening should be conducted among adolescents and adults who are at increased risk of hepatitis B virus (HBV) infection. The USPSTF named six categories of individuals at increased risk of infection: Persons born in countries with a 2% or higher prevalence of hepatitis B, such as Asia, Africa, the Pacific Islands, and some areas of South America; unvaccinated individuals born in the United States to parents from regions with a very high prevalence of HBV (≥8%); HIV-positive individuals; those who use injected drugs; men who have sex with men; and people who live with people who have HBV or who have HBV-infected sexual partners. It also recommended that pregnant women be screened for HBV infection during their first prenatal visit.

“I view the updated recommendations as an important document because it validates the importance of HBV screening, and the Grade B recommendation supports mandated insurance coverage for the screening test,” said Joseph Lim, MD, who is a professor of medicine at Yale University and director of the Yale Viral Hepatitis Program, both in New Haven, Conn.

Still, the recommendation could have gone further. Notably absent from the USPSTF document, yet featured in recommendations from the Centers for Disease Control and Prevention and the American Association for the Study of Liver Disease, are patients who have diabetes, are on immunosuppressive therapy, or have elevated liver enzymes or liver disease. Furthermore, a single-center study found that, among physicians administering immunosuppressive therapy, a setting in which HBV reactivation is a concern, there were low rates of screening for HBV infection, and the physicians did not reliably identify high-risk patients.

“This may also be viewed as a lost opportunity. Evidence suggests that risk factor–based screening is ineffective for the identification of chronic conditions such as hepatitis B. Risk factor–based screening is difficult to implement across health systems and exacerbates the burden on community-based organizations that are motivated to address viral hepatitis. It may further exacerbate labeling, stigma, and discrimination within already marginalized communities that are deemed to be at high risk,” said Dr. Lim.

A similar view was expressed by Avegail Flores, MD, medical director of liver transplantation at the Michael E. DeBakey Veterans Affairs Medical Center and assistant professor of medicine at Baylor College of Medicine, both in Houston. “This is a good launching point, and with further evidence provided, hopefully it will also bring in a broader conversation about other persons who are at risk but not included in these criteria.” Neither Dr. Lim nor Dr. Flores were involved in the study.

She noted that resistance to universal screening may be caused by the relatively low prevalence of hepatitis B infection in the United States. However, the CDC estimates that only about 61% of people infected with HBV are aware of it. “I don’t think we have done a good job screening those who are at risk,” said Dr. Flores.

Universal screening could help, but would have a low yield. Dr. Flores suggested expansion into other at-risk groups, such as Baby Boomers. With respect to other risk groups that could be stigmatized or discriminated against, Dr. Flores recalled her medical school days when some students went directly into underserved communities to provide information and screening services. “We have to think of creative ways of how to reach out to people, not just relying on the usual physician-patient relationship.”

There is no question that COVID-19 infection increases the risks of serious thromboembolic events, including pulmonary embolism (PE), but it also increases the risk of bleeding, complicating the benefit-to-risk calculations for anticoagulation, according to a review of data at the virtual Going Back to the Heart of Cardiology meeting.

“Bleeding is a significant cause of morbidity in patients with COVID-19, and this is an important concept to appreciate,” reported Rachel P. Rosovsky, MD, director of thrombosis research, Massachusetts General Hospital, Boston.

At least five guidelines, including those issued by the American College of Cardiology, International Society on Thrombosis and Haemostasis (ISTH), and the American College of Chest Physicians, have recently addressed anticoagulation in patients infected with COVID-19, but there are “substantive differences” between them, according to Dr. Rosovsky. The reason is that they are essentially no high quality trials to guide practice. Rather, the recommendations are based primarily on retrospective studies and expert opinion.

The single most common theme from the guidelines is that anticoagulation must be individualized to balance patient-specific risks of venous thromboembolism (VTE) and bleeding, said Dr. Rosovsky, whose group published a recent comparison of these guidelines (Flaczyk A et al. Crit Care 2020;24:559).

Although there is general consensus that all hospitalized patients with COVID-19 should receive anticoagulation unless there are contraindications, there are differences in the recommended intensity of the anticoagulation for different risk groups and there is even less is less consensus on the need to anticoagulate outpatients or patients after discharge, according to Dr. Rosovsky

In her own center, the standard is a prophylactic dose of low molecular weight heparin (LMWH) in an algorithm that calls for dose adjustments for some groups such as those with renal impairment or obesity. Alternative forms of anticoagulation are recommended for patients with a history of thrombocytopenia or are at high risk for hemorrhage. Full dose LMWH is recommended in patients already on an oral anticoagulant at time of hospitalization.

“The biggest question right now is when to consider increasing from a prophylactic dose to intermediate or full dose anticoagulation in high risk patients, especially those in the ICU patients,” Dr. Rosovsky said.

Current practices are diverse, according to a recently published survey led by Dr. Rosovsky (Rosovsky RP et al. Res Pract Thromb Haemost. 2020;4:969-83). According to the survey, which had responses from more than 500 physicians in 41 countries, 30% of centers escalate from a prophylactic dose of anticoagulation to an intermediate dose when patients move to the ICU. Although not all answered this question, 25% reported that they do not escalate at ICU transfer. For 15% of respondents, dose escalation is being offered to patients with a D-dimer exceeding six-times the upper limit of normal.

These practices have developed in the absence of prospective clinical trials, which are urgently needed, according to Dr. Rosovsky. The reason that trials specific to COVID-19 are particularly important is that this infection also engenders a high risk of major bleeding.

For example, in a multicenter retrospective study of 400 hospital-admitted COVID-19 patients the rates of major bleeding was 4.8% or exactly the same as the rate of radiographically confirmed VTE. At 7.6%, the rates of VTE and major bleeding were also exactly the same for ICU patients (Al-Samkari H et al. Blood 2020;136:489-500).

“An elevated D-dimer was a marker for both VTE and major bleeding,” reported Dr. Rosovsky, who was the senior author of this study. On the basis of odds ratio (OR), the risk of VTE was increased more than six-fold (OR, 6.79) and the risk of major bleeding by more than three-fold (OR, 3.56) when the D-dimer exceeded 2,500 ng/mL.

The risk of VTE from COVID-19 infection is well documented. For example, autopsy studies have shown widespread thrombosis, including PE, in patients who have died from COVID-19 infection, according to Dr. Rosovsky.

There is also evidence of benefit from anticoagulation. In an retrospective study from China undertaken early in the pandemic, there was no overall mortality benefit at 28 days among those who did receive LMWH when compared to those who did not, but there was a 20% absolute mortality benefit (52.4% vs. 32.8%; P = .017) in those with a D-dimer six-fold ULN (Tang N et al. J Thromb Haemost 2020;18:1094-9).

These types of data support the use of anticoagulation to manage VTE risk in at least some patients, but the reported rates of VTE across institutions and across inpatient and outpatient settings have varied “dramatically,” according to Dr. Rosovsky. The balance of VTE and major bleeding is delicate. In one retrospective study, the mortality advantage for therapeutic versus prophylactic dose of LMWH did not reach statistical significance, but the rate of major bleeding was nearly doubled (3.0% vs. 1.7%) (Nadkarni GN et al J Am Coll Cardiol 2020;76:1815-26).

Because of the many variables that might affect risk of VTE and risk of major bleeding in any individual patient, the benefit-to-risk calculation of anticoagulation is “complex,” according to Dr. Rosovsky. It is for this reason she urged clinicians to consider entering patients into clinical trials designed to generate evidence-based answers.

There is large and growing body of retrospective data that have helped characterize the risk of VTE and bleeding in patients with COVID-19, but “there is no substitute for a well-controlled clinical trial,” agreed Robert A. Harrington, MD, chairman of the department of medicine, Stanford (Calif.) University.

He and the comoderator of the session in which these data were presented agreed that anticoagulation must be administered within a narrow therapeutic window that will be best defined through controlled trial designs.

“There is a significant risk of doing harm,” said Fatima Rodriguez, MD, assistant professor of cardiology at Stanford University. She seconded the critical role of trial participation when possible and the need for clinical trials to better guide treatment decisions.

Cloth masks should not be considered equivalent to medical masks for the prevention of COVID-19 in clinical settings, according to an evidence review published Jan. 11 in Annals of Family Medicine.

Nevertheless, cloth masks may provide some degree of protection, filtration studies indicate. If clinicians use cloth masks, they should take into account the fit, material, and number of layers, the review authors wrote.

And if cloth masks are used as a last resort, such as during shortages of personal protective equipment (PPE), additional measures may help, such as pairing cloth masks with plastic face shields.

“We recommend frequent cloth mask changes to reduce the risk of moisture retention and washing according to hospital laundry standards to decrease the risk of ineffective cleaning,” review author Ariel Kiyomi Daoud, a researcher at the University of Colorado at Denver, Aurora, and colleagues wrote.

The investigators identified and analyzed nine studies related to cloth masks’ ability to prevent respiratory viral infections among health care clinicians. The studies generally were not specific to SARS-CoV-2. They focused on four nonrandomized trials, three laboratory efficacy studies, one single-case experiment, and one randomized controlled trial.
 

Filtration and fit

“Seven publications addressed the filtration efficacy of commercial cloth masks or materials used to create homemade masks ... in a laboratory setting,” the researchers wrote. These studies found that cloth materials prevent some level of penetration, but generally have “lesser filtration efficiency and greater variability than medical masks” do.

One study found that the materials with the greatest filtration efficacy – vacuum bags and tea towels – had low airflow, which limits their use.

Two studies found that additional layers may increase the viral filtration efficacy of cloth masks.

Several studies that assessed mask fit and airflow found that cloth masks “have worse fit and a greater level of particle leakage, compared to medical masks,” the authors reported. Most studies did not examine cloth masks’ ability to protect wearers from respiratory droplets or contact, which the World Health Organization consider the primary means of SARS-CoV-2 spread, with aerosols playing a smaller role. “Thus, we must interpret these results with caution in the context of COVID-19,” the authors wrote. “For a primary care clinician without access to medical masks, our qualitative synthesis of the literature suggests that it is better to wear a cloth mask than no mask,” as long as other protective measures are considered along with cloth mask use.

Generally consistent guidance

Agencies and researchers have shared similar recommendations about the use of cloth masks in health care settings.

“Health care workers are at the frontline and they need to be protected,” said Abrar Ahmad Chughtai, MBBS, MPH, PhD, an epidemiologist at University of New South Wales, Sydney, in an interview. “Many studies show that respirators are more effective, compared to medical masks, and medical masks are more effective, compared to cloth masks. So ideally, all frontline health care workers should use respirators. If respirators are not available, then medical masks should be used. Cloth masks are not as effective as medical masks and ideally should not be used in health care settings.”

Dr. Chughtai has written about cloth masks for protection against SARS-CoV-2 and was an investigator for a 2015 randomized trial that compared medical masks and cloth masks in health care workers.

In that trial, which was considered in the review, greater rates of influenza-like illness occurred in the cloth mask arm, compared with the medical mask arm.

“Studies show that three or more layers of cloth may reduce the spread of droplets and aerosols from the wearers,” Dr. Chughtai said. “So, cloth masks may be used in community settings to prevent spread of infections from the sick, particularly asymptomatic, people.”

In addition, cloth masks “may be used by health care workers as a last resort, if no other option is available,” he said. In that case, they should have at least three layers, fit to the face, and be washed regularly.
 

Not considered PPE

According to routine infection prevention and control recommendations for health care personnel from the Centers for Disease Control and Prevention, face masks – often referred to as surgical masks or procedure masks – should be worn by workers “at all times while they are in the healthcare facility, including in break rooms or other spaces where they might encounter coworkers.”

Unlike cloth masks, face masks offer “protection for the wearer against exposure to splashes and sprays of infectious material from others,” as well as source control, the agency says. Health care personnel “should remove their respirator or face mask, perform hand hygiene, and put on their cloth mask when leaving the facility at the end of their shift,” according to the CDC.

“Cloth masks are NOT PPE and should not be worn for the care of patients with suspected or confirmed COVID-19 or other situations where use of a respirator or face mask is recommended,” the agency notes.

When respirators or face masks are unavailable, health care personnel “might use cloth masks as a last resort for care of patients with suspected or confirmed diagnosis for which face mask or respirator use is normally recommended,” according to CDC guidance.

In that scenario, cloth masks “should ideally be used in combination with a face shield that covers the entire front (that extends to the chin or below) and sides of the face,” the CDC says.
 

Limited data for comparisons

A Dec. 29, 2020, update in Annals of Internal Medicine about masks for prevention of respiratory virus infections highlighted two recent studies in the United States that reported on mask use in health care settings. A study of more than 16,000 health care workers and first responders found that those who used an N95 or surgical mask all of the time were less likely to have SARS-CoV-2 antibodies, compared with workers who did not wear masks all the time. The adjusted odds ratio with consistent N95 use was 0.83, and the aOR with consistent surgical mask use was 0.86.

In the second study, which included more than 20,000 asymptomatic health care workers, risk for infection was reduced with any mask use versus no mask use (OR, 0.58). An N95 mask was associated with decreased risk versus a surgical mask (OR, 0.76). The studies had methodological limitations, however, and “evidence for various comparisons about mask use in health care settings and risk for SARS-CoV-2 remains insufficient,” the authors of the update wrote.

The Annals of Family Medicine review authors had no relevant disclosures. Dr. Chughtai has tested filtration of 3M masks and worked with CleanSpace Technology to research fit testing of respirators, and the 2015 randomized trial was funded by an Australian Research Council Linkage Grant with 3M as a partner on the grant. The Dec. 29, 2020, update was of a review that originally was supported by grants from the Agency for Healthcare Research Quality.

“Studies show that three or more layers of cloth may reduce the spread of droplets and aerosols from the wearers,” Dr. Chughtai said. “So, cloth masks may be used in community settings to prevent spread of infections from the sick, particularly asymptomatic, people.”

In addition, cloth masks “may be used by health care workers as a last resort, if no other option is available,” he said. In that case, they should have at least three layers, fit to the face, and be washed regularly.
 

Not considered PPE

According to routine infection prevention and control recommendations for health care personnel from the Centers for Disease Control and Prevention, face masks – often referred to as surgical masks or procedure masks – should be worn by workers “at all times while they are in the healthcare facility, including in break rooms or other spaces where they might encounter coworkers.”

Unlike cloth masks, face masks offer “protection for the wearer against exposure to splashes and sprays of infectious material from others,” as well as source control, the agency says. Health care personnel “should remove their respirator or face mask, perform hand hygiene, and put on their cloth mask when leaving the facility at the end of their shift,” according to the CDC.

“Cloth masks are NOT PPE and should not be worn for the care of patients with suspected or confirmed COVID-19 or other situations where use of a respirator or face mask is recommended,” the agency notes.

When respirators or face masks are unavailable, health care personnel “might use cloth masks as a last resort for care of patients with suspected or confirmed diagnosis for which face mask or respirator use is normally recommended,” according to CDC guidance.

In that scenario, cloth masks “should ideally be used in combination with a face shield that covers the entire front (that extends to the chin or below) and sides of the face,” the CDC says.
 

Limited data for comparisons

A Dec. 29, 2020, update in Annals of Internal Medicine about masks for prevention of respiratory virus infections highlighted two recent studies in the United States that reported on mask use in health care settings. A study of more than 16,000 health care workers and first responders found that those who used an N95 or surgical mask all of the time were less likely to have SARS-CoV-2 antibodies, compared with workers who did not wear masks all the time. The adjusted odds ratio with consistent N95 use was 0.83, and the aOR with consistent surgical mask use was 0.86.

In the second study, which included more than 20,000 asymptomatic health care workers, risk for infection was reduced with any mask use versus no mask use (OR, 0.58). An N95 mask was associated with decreased risk versus a surgical mask (OR, 0.76). The studies had methodological limitations, however, and “evidence for various comparisons about mask use in health care settings and risk for SARS-CoV-2 remains insufficient,” the authors of the update wrote.

The Annals of Family Medicine review authors had no relevant disclosures. Dr. Chughtai has tested filtration of 3M masks and worked with CleanSpace Technology to research fit testing of respirators, and the 2015 randomized trial was funded by an Australian Research Council Linkage Grant with 3M as a partner on the grant. The Dec. 29, 2020, update was of a review that originally was supported by grants from the Agency for Healthcare Research Quality.

Cloth masks should not be considered equivalent to medical masks for the prevention of COVID-19 in clinical settings, according to an evidence review published Jan. 11 in Annals of Family Medicine.

Nevertheless, cloth masks may provide some degree of protection, filtration studies indicate. If clinicians use cloth masks, they should take into account the fit, material, and number of layers, the review authors wrote.

And if cloth masks are used as a last resort, such as during shortages of personal protective equipment (PPE), additional measures may help, such as pairing cloth masks with plastic face shields.

“We recommend frequent cloth mask changes to reduce the risk of moisture retention and washing according to hospital laundry standards to decrease the risk of ineffective cleaning,” review author Ariel Kiyomi Daoud, a researcher at the University of Colorado at Denver, Aurora, and colleagues wrote.

The investigators identified and analyzed nine studies related to cloth masks’ ability to prevent respiratory viral infections among health care clinicians. The studies generally were not specific to SARS-CoV-2. They focused on four nonrandomized trials, three laboratory efficacy studies, one single-case experiment, and one randomized controlled trial.
 

Filtration and fit

“Seven publications addressed the filtration efficacy of commercial cloth masks or materials used to create homemade masks ... in a laboratory setting,” the researchers wrote. These studies found that cloth materials prevent some level of penetration, but generally have “lesser filtration efficiency and greater variability than medical masks” do.

One study found that the materials with the greatest filtration efficacy – vacuum bags and tea towels – had low airflow, which limits their use.

Two studies found that additional layers may increase the viral filtration efficacy of cloth masks.

Several studies that assessed mask fit and airflow found that cloth masks “have worse fit and a greater level of particle leakage, compared to medical masks,” the authors reported. Most studies did not examine cloth masks’ ability to protect wearers from respiratory droplets or contact, which the World Health Organization consider the primary means of SARS-CoV-2 spread, with aerosols playing a smaller role. “Thus, we must interpret these results with caution in the context of COVID-19,” the authors wrote. “For a primary care clinician without access to medical masks, our qualitative synthesis of the literature suggests that it is better to wear a cloth mask than no mask,” as long as other protective measures are considered along with cloth mask use.

Generally consistent guidance

Agencies and researchers have shared similar recommendations about the use of cloth masks in health care settings.

“Health care workers are at the frontline and they need to be protected,” said Abrar Ahmad Chughtai, MBBS, MPH, PhD, an epidemiologist at University of New South Wales, Sydney, in an interview. “Many studies show that respirators are more effective, compared to medical masks, and medical masks are more effective, compared to cloth masks. So ideally, all frontline health care workers should use respirators. If respirators are not available, then medical masks should be used. Cloth masks are not as effective as medical masks and ideally should not be used in health care settings.”

Dr. Chughtai has written about cloth masks for protection against SARS-CoV-2 and was an investigator for a 2015 randomized trial that compared medical masks and cloth masks in health care workers.
