Treatment with the sodium-glucose transporter 2 inhibitor dapagliflozin reduced the risk for cardiovascular disease or hospitalization for heart failure (CVD/HHF) in patients with diabetes, regardless of the duration of the disease, but had a greater protective benefit against major adverse cardiovascular events (MACE) and renal events in patients with longer disease duration, according to new findings from a post hoc analysis of the DECLARE-TIMI 58 trial.

The positive effect of dapagliflozin in patients with MACE – which includes myocardial infarction (MI), CVD, and ischemic stroke – may have been driven by lower rates of MI and ischemic stroke with the drug, compared with placebo, in patients with longer disease duration, wrote Harpreet S. Bajaj, MD, and colleagues. Their report is in Diabetes, Obesity and Metabolism (2020 Feb 23. doi: 10.1111/dom.14011).

It has been previously reported that the risk for complications in diabetes increases with increasing duration of the disease. Recent studies with SGLT-2 inhibitors have shown that the drugs improve cardiovascular and renal outcomes in diabetes, and they are recommended by the American Diabetes Association as second-line therapy in patients with atherosclerotic cardiovascular disease, chronic kidney disease, or heart failure. The European Society of Cardiology and the European Association for the Study of Diabetes recommend that patients with diabetes patients who have three or more risk factors, or those with a disease duration of more than 20 years, should be deemed very high risk and be considered for early treatment with SGLT2 inhibitors.

“The MACE benefit observed with dapagliflozin in this study in patients with diabetes duration of [more than] 20 years, clearly supports that notion,” the authors wrote.

In DECLARE-TIMI 58, 17,160 patients with type 2 diabetes received dapagliflozin or placebo and were followed for a median of 4.2 years. Of those patients, 22.4% had a disease duration of fewer than 5 years; 27.6%, a duration of 5-10 years; 23.0%, 10-15 years; 14.2%, 10-15 years; and 12.9%, more than 20 years. The median duration of disease was 11 years.

Patients in all the age groups had similar reductions in CVD/HHF, compared with placebo, with hazard ratios of 0.79 (disease duration of 5 or fewer years), 0.86, 0.92, 0.81, and 0.75 (duration of 20 years), respectively (interaction trend P = .760).

Treatment with dapagliflozin reduced the incidence of MACE, but the benefit was more apparent in patients with longer-term disease: HR, 1.08; 1.02; 0.94; 0.92; and 0.67, respectively (interaction trend P = .004). Similar trends were seen with MI (interaction trend P = .019) and ischemic stroke (interaction trend P = .015).

The researchers also reported improved benefits in renal-specific outcome with increasing disease duration, with HRs ranging from 0.79 in patients with diabetes duration of fewer than 5 years, to 0.42 in those with a duration of more than 20 years (interaction trend P = .084).

Limitations of the study include the fact that the information about diabetes duration relied on patient reports, and that the original trial was not powered for all subgroup interactions. This authors emphasized that this was a post hoc analysis and as such, should be considered hypothesis generating.

All but two of the authors reported relationships with Astra Zeneca, which funded the study, and other drug companies.

A multifaceted intervention significantly changed clinicians’ use of antibiotics to treat urinary tract infections (UTIs) in children, according to data from more than 2,000 cases observed between January 2014 and September 2018.

“Changing clinicians’ antibiotic prescribing practices can be challenging; barriers to change include lack of awareness of new evidence, competing clinical demands, and concern about treatment failure,” wrote Matthew F. Daley, MD, of Kaiser Permanente Colorado, Aurora, and colleagues in Pediatrics.

To promote judicious antibiotic use, the researchers designed an intervention including the development of new local UTI guidelines; a live, case-based educational session; emailed knowledge assessments before and after the session; and a specific UTI order set in the EHR.

The researchers divided the study period into a preintervention period (January 1, 2014, to April 25, 2017) and a postintervention period (April 26, 2017, to September 30, 2018). They collected data on 2,142 incident outpatient UTIs; 1,636 from the preintervention period and 506 from the postintervention period. The patients were younger than 18 years and older than 60 days, and children with complicated urologic or neurologic conditions were excluded.

Overall, the proportion of UTIs treated with first-line antibiotics increased significantly from 43% preintervention to 62% postintervention (P less than .0001). In particular, the use of first-line, narrow spectrum cephalexin increased significantly from 29% during the preintervention period to 53% during the postintervention period (P less than .0001). In addition, use of broad spectrum cefixime decreased from 17% during the preintervention period to 3% during the postintervention period (P less than .0001). These changes in prescribing patterns continued through the end of the study period, the researchers said.

The study was limited by several factors, notably that “the interrupted time-series design prevents us from inferring that the intervention caused the observed change in practice,” the researchers wrote. However, other factors including the immediate change in prescribing patterns after the intervention, multiple time points, large sample size, and consistent UTI case mix support the impact of the intervention, they suggested. Although the results might not translate completely to other settings, “developing a UTI-specific EHR order set is relatively straightforward” and might be applied elsewhere, they noted.

“Despite the limitations inherent in a nonexperimental study design, the methods and interventions developed in the current study may be informative to other learning health systems and other content areas when conducting organization-wide quality improvement initiatives,” they concluded.

The study was supported by unrestricted internal resources from the Colorado Permanente Medical Group. The researchers had no financial conflicts to disclose.

As the first COVID-19 outbreak in the United States emerges in Washington State, the city of Seattle, King County, and Washington State health officials provided the beginnings of a roadmap for how the region will address the rapidly evolving health crisis.

Health officials announced that four new cases were reported over the weekend in King County, Wash. There have now been 10 hospitalizations and 6 COVID-19 deaths at Evergreen Health, Kirkland, Wash. Of the deaths, five were King County residents and one was a resident of Snohomish County. Three patients died on March 1; all were in their 70s or 80s with comorbidities. Two had been residents of the Life Care senior residential facility that is at the center of the Kirkland outbreak. The number of cases in Washington now totals 18, with four cases in Snohomish County and the balance in neighboring King County.

Approximately 29 cases are under investigation with test results pending; a Centers for Disease Control and Prevention (CDC) team is on-site.

Speaking at a news conference March 2, officials sought to strike a balance between giving the community a realistic appraisal of the likely scope of the COVID-19 outbreak and avoiding sparking a panic.

“This is a complex and unprecedented challenge nationally, globally, and locally. The vast majority of the infected have mild or moderate disease and do not need hospitalization,” said Jeffrey Duchin, MD, health officer and chief, Communicable Disease EPI/Immunization Section, Public Health, Seattle and King County, and a professor of infectious diseases at the University of Washington, Seattle. “On the other hand, it’s obvious that this infection can cause very serious disease in people who are older and have underlying health conditions. We expect cases to continue to increase. We are taking the situation extremely seriously; the risk for all of us becoming infected is increasing. ...There is the potential for many to become ill at the same time.”

Among the measures being taken immediately are the purchase by King County of a hotel to house individuals who require isolation and those who are convalescing from the virus. Officials are also placing a number of prefabricated stand-alone housing units on public grounds in Seattle, with the recognition that the area has a large transient and homeless community. The stand-alone units will house homeless individuals who need isolation, treatment, or recuperation but who aren’t ill enough to be hospitalized.

Dr. Duchin said that testing capacity is ramping up rapidly in Washington State: The state lab can now accommodate up to about 200 tests daily, and expects to be able to do up to 1,000 daily soon. The University of Washington’s testing capacity will come online March 2 or 3 as a testing facility with similar initial and future peak testing capacities.

The testing strategy will continue to include very ill individuals with pneumonia or other respiratory illness of unknown etiology, but will also expand to include less ill people. This shift is being made in accordance with a shift in CDC guidelines, because of increased testing capacity, and to provide a better picture of the severity, scope, geography, and timing of the current COVID-19 outbreak in the greater Seattle area.

No school closures or cancellation of gatherings are currently recommended by public health authorities. There are currently no COVID-19 cases in Washington schools. The expectation is that any recommendations regarding closures will be re-evaluated as the outbreak progresses.

Repeatedly, officials asked the general public to employ basic measures such as handwashing and avoidance of touching the face, and to spare masks for the ill and for those who care for them. “The vast majority of people will not have serious illness. In turn we need to do everything we can to help those health care workers. I’m asking the public to do things like save the masks for our health care workers. …We need assets for our front-line health care workers and also for those who may be needing them,” said King County Health Department director Patty Hayes, RN, MN.

Now is also the time for households to initiate basic emergency preparedness measures, such as having adequate food and medication, and to make arrangements for childcare in the event of school closures, said several officials.

“We can decrease the impact on our health care system by reducing our individual risk. We are making individual- and community-level recommendations to limit the spread of disease. These are very similar to what we recommend for influenza,” said Dr. Duchin.

Ettore Palazzo, MD, chief medical and quality officer at EvergreenHealth, gave a sense of how the hospital is coping with being Ground Zero for COVID-19 in the United States. “We have made adjustments for airborne precautions,” he said, including transforming the entire critical care unit to a negative pressure unit. “We have these capabilities in other parts of the hospital as well.” Staff are working hard, but thus far staffing has kept pace with demand, he said, but all are feeling the strain already.

Dr. Duchin made the point that Washington is relatively well equipped to handle the increasingly likely scenario of a large spike in coronavirus cases, since it’s part of the Northwest Healthcare Response Network. The network is planning for sharing resources such as staff, respirators, and intensive care unit beds as circumstances warrant.

“What you just heard illustrates the challenge of this disease,” said Dr. Duchin, summing up. “The public health service and clinical health care delivery systems don’t have the capacity to track down every case in the community. I’m guessing we will see more cases of coronavirus than we see of influenza. At some point we will be shifting from counting every case” to focusing on outbreaks and the critically ill in hospitals, he said.

“We are still trying to contain the outbreak, but we are at the same time pivoting to a more community-based approach,” similar to the approach with influenza, said Dr. Duchin.

I’m asking the public to do things like save the masks for our health care workers. …We need assets for our front-line health care workers and also for those who may be needing them,” said King County Health Department director Patty Hayes, RN, MN.

Now is also the time for households to initiate basic emergency preparedness measures, such as having adequate food and medication, and to make arrangements for childcare in the event of school closures, said several officials.

“We can decrease the impact on our health care system by reducing our individual risk. We are making individual- and community-level recommendations to limit the spread of disease. These are very similar to what we recommend for influenza,” said Dr. Duchin.

Ettore Palazzo, MD, chief medical and quality officer at EvergreenHealth, gave a sense of how the hospital is coping with being Ground Zero for COVID-19 in the United States. “We have made adjustments for airborne precautions,” he said, including transforming the entire critical care unit to a negative pressure unit. “We have these capabilities in other parts of the hospital as well.” Staff are working hard, but thus far staffing has kept pace with demand, he said, but all are feeling the strain already.

Dr. Duchin made the point that Washington is relatively well equipped to handle the increasingly likely scenario of a large spike in coronavirus cases, since it’s part of the Northwest Healthcare Response Network. The network is planning for sharing resources such as staff, respirators, and intensive care unit beds as circumstances warrant.

“What you just heard illustrates the challenge of this disease,” said Dr. Duchin, summing up. “The public health service and clinical health care delivery systems don’t have the capacity to track down every case in the community. I’m guessing we will see more cases of coronavirus than we see of influenza. At some point we will be shifting from counting every case” to focusing on outbreaks and the critically ill in hospitals, he said.

“We are still trying to contain the outbreak, but we are at the same time pivoting to a more community-based approach,” similar to the approach with influenza, said Dr. Duchin.

A 59-year-old man is admitted with abdominal pain. He has a history of pancreatitis. A contrast CT scan is ordered. He reports a history of severe shellfish allergy when the radiology tech checks him in for the procedure. You are paged regarding what to do:

A) Continue with scan as ordered.

B) Switch to MRI scan.

C) Switch to MRI scan with gadolinium.

D) Continue with CT with contrast, give dose of Solu-Medrol.

E) Continue with CT with contrast give IV diphenhydramine.
 

The correct answer here is A, This patient can receive his scan and receive contrast as ordered.

For many years, patients have been asked about shellfish allergy as a proxy for having increased risk when receiving iodine containing contrast. The mistaken thought was that shellfish contains iodine, so allergy to shellfish was likely to portend allergy to iodine.

Allergy to shellfish is caused by individual proteins that are definitely not in iodine-containing contrast.¹ Beaty et al. studied the prevalence of the belief that allergy to shellfish is tied to iodine allergy in a survey given to 231 faculty radiologists and interventional cardiologists.² Almost 70% responded that they inquire about seafood allergy before procedures that require iodine contrast, and 37% reported they would withhold the contrast or premedicate patients if they had a seafood allergy.

In a more recent study, Westermann-Clark and colleagues surveyed 252 health professionals before and after an educational intervention to dispel the myth of shellfish allergy and iodinated contrast reactions.³ Before the intervention, 66% of participants felt it was important to ask about shellfish allergies and 93% felt it was important to ask about iodine allergies; 26% responded that they would withhold iodinated contrast material in patients with a shellfish allergy, and 56% would withhold in patients with an iodine allergy. A total of 62% reported they would premedicate patients with a shellfish allergy and 75% would premedicate patients with an iodine allergy. The numbers declined dramatically after the educational intervention.

Patients who have seafood allergy have a higher rate of reactions to iodinated contrast, but not at a higher rate than do patients with other food allergies or asthma.⁴ Most radiology departments do not screen for other food allergies despite the fact these allergies have the same increased risk as for patients with a seafood/shellfish allergy. These patients are more allergic, and in general, are more likely to have reactions. The American Academy of Allergy, Asthma, and Immunology recommends not routinely ordering low- or iso-osmolar radiocontrast media or pretreating with either antihistamines or steroids in patients with a history of seafood allergy.⁵

• It is unnecessary and unhelpful to ask patients about seafood allergies before ordering radiologic studies involving contrast.
• Iodine allergy does not exist.

ORLANDO – For critically ill, mechanically ventilated patients, a strategy of no sedation resulted in a mortality rate that was not significantly different from a strategy of light sedation with interruption, according to results of a multicenter, randomized trial.

The lack of sedation did significantly improve certain secondary endpoints, including a reduced number of thromboembolic events and preservation of physical function, according to Palle Toft, PhD, DMSc, of Odense (Denmark) University Hospital.

However, the 90-day mortality rate was 42.4% in the no-sedation group versus 37.0% in the sedation group in the NONSEDA study, which was intended to test the hypothesis that mortality would be lower in the no-sedation group.

That 5.4 percentage point difference between arms in NONSEDA was not statistically significant (P = .65) in results of the study, presented at the Critical Care Congress sponsored by the Society of Critical Care Medicine and concurrently published in the New England Journal of Medicine.

Yet that mortality trend is in the “opposite direction” of an earlier, single-center trial by Dr. Toft and colleagues, noted Claude Guérin, MD, PhD, in a related editorial that also appeared in the journal. In that earlier study, the reported hospital mortality rates were 36% for no sedation and 47% for sedation with daily interruption.

“The results from this trial [NONSEDA] are important because they arouse concern about omitting sedation in mechanically ventilated patients and reinforce the need to monitor sedation clinically, with the aim of discontinuing it as early as possible or at least interrupting it daily,” Dr. Guérin wrote in his editorial.

That said, the earlier, single-center trial was not statistically powered to show between-group differences in mortality, Dr. Toft and coauthors wrote in their journal article.

In his presentation, Dr. Toft emphasized that light sedation with a wake-up trial was “comparable” with no sedation with regard to mortality.

“I think my main message is that we have to individualize patient treatment,” Dr. Toft told attendees at a late-breaking literature session. “Many patients would benefit from nonsedation, and some would benefit by light sedation with a daily wake-up trial. We have to respect patient autonomy, and try to establish a two-way communication with patients in 2020.”

Sandra L. Kane-Gill, PharmD, treasurer of SCCM and assistant professor of pharmacy and therapeutics at the University of Pittsburgh, said that current SCCM guidelines recommend using light sedation in critically ill, mechanically ventilated adults.

“I think we should stay consistent with what the guidelines are saying,” Dr. Kane-Gill said in an interview. “How you do that may vary, but targeting light sedation is consistent with what the evidence is suggesting in those guidelines.”

The depth of sedation between the no-sedation group in the light sedation group in the present study was not as great as the investigators had anticipated, which may explain the lack of statistically significant difference in mortality, according to Dr. Kane-Gill.

According to the report, 38.4% of patients in the no-sedation group received medication for sedation during their ICU stay, while Richmond Agitation and Sedation Scores increased in both groups, indicating a more alert state in both groups.

The multicenter NONSEDA trial included 700 mechanically ventilated ICU patients randomized either to no sedation or to light sedation, such that the patient was arousable, with daily interruption.

Previous studies have shown that daily interruption of sedation reduced mechanical ventilation duration, ICU stay length, and mortality in comparison with no interruption, the investigators noted.

While mortality at 90 days did not differ significantly between the no-sedation and light-sedation approaches, no sedation reduced thromboembolic events, Dr. Toft said at the meeting. The number of thrombolic events within 90 days was 10 (5%) in the sedation group and 1 (0.5%) in the no-sedation group (P less than .05), according to the reported data.

Likewise, several measures of physical function significantly improved in an a prior defined subgroup of 200 patients, he said. Those measures included hand grip at extubation and ICU discharge, as well as scores on the Barthel Index for Activities of Daily Living.

Nonsedation might improve kidney function, based on other reported outcomes of the study, Dr. Toft said. The number of coma- and delirium-free days was 3.0 in the no-sedation group versus 1.0 in the sedation group (P less than .01), he added.

The benefits of no sedation may extend beyond objective changes in health outcomes, according to Dr. Toft. “The patients are able to communicate with the staff, they might be able to enjoy food, in the evening they can look at the television instead of being sedated – and they can be mobilized and they can write their opinion about the treatments to the doctor, and in this way, you have two-way communication,” he explained in his presentation.

Dr. Toft reported that he had no financial relationships to disclose.

Antibiotic resistance in strains of Streptococcus pneumoniae has been rising since 2013 because of changing susceptibility profiles, based on data from 1,201 isolates collected from 448 children in primary care settings.

“New strains expressing capsular serotypes not included in the 13-valent pneumococcal conjugate vaccine are emerging to cause disease, and strains that acquire antibiotic resistance are increasing in frequency due to their survival of the fittest advantage,” wrote Ravinder Kaur, PhD, of Rochester (N.Y.) General Hospital Research Institute, and colleagues.

Similar Darwinian principles occurred after the introduction of PCV-7, the study authors added.

In a prospective cohort study published in Clinical Infectious Diseases, the researchers reviewed 1,201 isolates collected from the nasopharynx during healthy periods, and from the nasopharynx and middle ear fluid (MEF) during episodes of acute otitis media, in children aged 6-36 months who were seen in primary care settings.

The isolates were collected during 2006-2016 to reflect the pre- and post-PCV13 era. Children received PCV-7 from 2006 until April 2010, and received PCV-13 after April 2010.

Overall, the number of acute otitis media (AOM) cases caused by S. pneumoniae was not significantly different between the PCV-7 and PCV-13 eras, nor was the frequency of pneumococci identified in the nasopharynx during healthy visits and visits at the start of an AOM infection.

The researchers examined susceptibility using minimum inhibitory concentrations (MIC). During healthy visits, the MIC₅₀ of isolated pneumococci was low (no greater than 0.06 mcg/mL) for all four beta-lactam drugs tested. And it didn’t change significantly over the study years.

In contrast, among the nasopharyngeal and MEF isolates during AOM, the MIC₅₀ to penicillin, amoxicillin, ceftriaxone, and meropenem during 2013-2016 rose significantly, the investigators said.

A change in antibiotic susceptibility within a subtype also contributed to the development of PCV-13 resistance.

The study authors identified three serotypes that affected the changes in susceptibility in their study population. Serotypes 35B and 35F increased their beta-lactam resistance during 2013-2016, and serotype 11A had a higher MIC to quinolones and became more prevalent during 2013-2016. Those three serotypes accounted for most of the change in antibiotic susceptibility, the researchers said.

In addition, “the frequency of strains resistant to penicillin and amoxicillin decreased with the introduction of PCV-13, but rebounded to levels similar to those before PCV-13 introduction by 2015-2016,” the investigators noted.

The study findings were limited by several factors, including the homogeneous study population and potential lack of generalizability to other settings. In addition, the researchers did not study antibiotic consumption or antibiotic treatment failure, and they could not account for potential AOM cases that may have been treated in settings other than primary care.

However, the investigators said the results support the need for additional studies and attention to the development of the next generation of PCVs, the PCV-15 and PCV-20. Both include serotypes 22F and 33F, but neither includes 35B or 35F. The PCV-20 also includes 11A and 15B.

The study was supported in part by the National Institutes of Health and Sanofi Pasteur. Some isolates collected during the 2010-2013 time period were part of a study supported by Pfizer. The researchers had no relevant financial conflicts to disclose.

The isolates were collected during 2006-2016 to reflect the pre- and post-PCV13 era. Children received PCV-7 from 2006 until April 2010, and received PCV-13 after April 2010.

Overall, the number of acute otitis media (AOM) cases caused by S. pneumoniae was not significantly different between the PCV-7 and PCV-13 eras, nor was the frequency of pneumococci identified in the nasopharynx during healthy visits and visits at the start of an AOM infection.

The researchers examined susceptibility using minimum inhibitory concentrations (MIC). During healthy visits, the MIC₅₀ of isolated pneumococci was low (no greater than 0.06 mcg/mL) for all four beta-lactam drugs tested. And it didn’t change significantly over the study years.

In contrast, among the nasopharyngeal and MEF isolates during AOM, the MIC₅₀ to penicillin, amoxicillin, ceftriaxone, and meropenem during 2013-2016 rose significantly, the investigators said.

A change in antibiotic susceptibility within a subtype also contributed to the development of PCV-13 resistance.

The study authors identified three serotypes that affected the changes in susceptibility in their study population. Serotypes 35B and 35F increased their beta-lactam resistance during 2013-2016, and serotype 11A had a higher MIC to quinolones and became more prevalent during 2013-2016. Those three serotypes accounted for most of the change in antibiotic susceptibility, the researchers said.

In addition, “the frequency of strains resistant to penicillin and amoxicillin decreased with the introduction of PCV-13, but rebounded to levels similar to those before PCV-13 introduction by 2015-2016,” the investigators noted.

The study findings were limited by several factors, including the homogeneous study population and potential lack of generalizability to other settings. In addition, the researchers did not study antibiotic consumption or antibiotic treatment failure, and they could not account for potential AOM cases that may have been treated in settings other than primary care.

However, the investigators said the results support the need for additional studies and attention to the development of the next generation of PCVs, the PCV-15 and PCV-20. Both include serotypes 22F and 33F, but neither includes 35B or 35F. The PCV-20 also includes 11A and 15B.

The study was supported in part by the National Institutes of Health and Sanofi Pasteur. Some isolates collected during the 2010-2013 time period were part of a study supported by Pfizer. The researchers had no relevant financial conflicts to disclose.

Antibiotic resistance in strains of Streptococcus pneumoniae has been rising since 2013 because of changing susceptibility profiles, based on data from 1,201 isolates collected from 448 children in primary care settings.

“New strains expressing capsular serotypes not included in the 13-valent pneumococcal conjugate vaccine are emerging to cause disease, and strains that acquire antibiotic resistance are increasing in frequency due to their survival of the fittest advantage,” wrote Ravinder Kaur, PhD, of Rochester (N.Y.) General Hospital Research Institute, and colleagues.

The first death in the United States from the novel coronavirus (COVID-19) was a Washington state man in his 50s who had underlying health conditions, state health officials announced on Feb 29. At the same time, officials there are investigating a possible COVID-19 outbreak at a long-term care facility.

Washington state officials reported two other presumptive positive cases of COVID-19, both of whom are associated with LifeCare of Kirkland, Washington. One is a woman in her 70s who is a resident at the facility and the other is a woman in her 40s who is a health care worker at the facility.

Additionally, many residents and staff members at the facility have reported respiratory symptoms, according to Jeff Duchin, MD, health officer for public health in Seattle and King County. Among the more than 100 residents at the facility, 27 have respiratory symptoms; while among the 180 staff members, 25 have reported symptoms.

Overall, these reports bring the total number of U.S. COVID-19 cases detected by the public health system to 22, though that number is expected to climb as these investigations continue.

The general risk to the American public is still low, including residents in long-term care facilities, Nancy Messonnier, MD, director of the National Center for Immunization and Respiratory Diseases at the Centers for Disease Control and Prevention, said during the Feb. 29 press briefing. Older people are are higher risk, however, and long-term care facilities should emphasize handwashing and the early identification of individuals with symptoms.

Dr. Duchin added that health care workers who are sick should stay home and that visitors should be screened for symptoms, the same advice offered to limit the spread of influenza at long-term care facilities.

The CDC briefing comes after President Trump held his own press conference at the White House where he identified the person who had died as being a woman in her 50s who was medically at risk.

During that press conference, Anthony S. Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, said that the current pattern of disease with COVID-19 suggests that 75%-80% of patients will have mild illness and recover, while 15%-20% will require advanced medical care.

For the most part, the more serious cases will occur in those who are elderly or have underlying medical conditions. There is “no indication” that individuals who recover from the virus are becoming re-infected, Dr. Fauci said.

The administration also announced a series of actions aimed at slowing the spread of the virus and responding to it. On March 2, President Trump will meet with leaders in the pharmaceutical industry at the White House to discuss vaccine development. The administration is also working to ensure an adequate supply of face masks. Vice President Mike Pence said there are currently more than 40 million masks available, but that the administration has received promises of 35 million more masks per month from manufacturers. Access to masks will be prioritized for high-risk health care workers, Vice President Pence said. “The average American does not need to go out and buy a mask,” he added.

Additionally, Vice President Pence announced new travel restrictions with Iran that would bar entry to the United States for any foreign national who visited Iran in the last 14 days. The federal government is also advising Americans not to travel to the regions in Italy and South Korea that have been most affected by COVID-19. The government is also working with officials in Italy and South Korea to conduct medical screening of anyone coming into the United States from those countries.

In a telebriefing on the COVID-19 outbreak, Nancy Messonnier, MD, director of the National Center for Immunization and Respiratory Diseases at the Centers for Disease Control and Prevention announced that the agency has updated the definition of “Person Under Investigation,” or PUI, for the disease.

The definition has been revised “to meet the needs of this rapidly evolving situation,” she said. The new PUI definition includes travel to more geographic areas to reflect this past week’s marked uptick in coronavirus activity in Italy and Iran. In addition to these countries and China, recent travel to Japan or South Korea also constitutes an epidemiologic risk factor which, in conjunction with clinical features, warrant an individual being classified as a PUI. These five countries each now have widespread person-to-person transmission of the virus.

Dr. Messonnier left open the possibility that the PUI definition would continue to evolve if such transmission within communities becomes more common. Asked whether the small number of U.S. cases thus might be an artifact of low test volumes, she said, “We aggressively controlled our borders to slow the spread. This was an intentional U.S. strategy. The CDC has always had the capacity to test rapidly from the time the sequence was available. ...We have been testing aggressively.”

The original PUI definition, she explained, emphasized individuals with fever, cough, or trouble breathing who had traveled recently from areas with COVID-19 activity, in particular China’s Hubei province. “We have been most focused on symptomatic people who are closely linked to, or who had, travel history, but our criteria also allow for clinical discretion,” she said. “There is no substitute for an astute clinician on the front lines of patient care.”

The first COVID-19 case from person-to-person spread was reported on Feb. 27. “At this time, we don’t know how or where this person became infected,” said Dr. Messonnier, although investigations are still underway. She responded to a question about whether the CDC delayed allowing COVID-19 testing for the patient for several days, as was reported in some media accounts. “According to CDC records, the first call we got was Feb. 23,” when public health officials in California reported a severely ill person with no travel abroad and no known contacts with individuals that would trigger suspicions for coronavirus. The CDC recommended COVID-19 testing on that day, she said.

Dr. Messonnier declined to answer questions about a whistleblower report alleging improper training and inadequate protective measures for Department of Health & Human Services workers at the quarantine center at Travis Air Force Base, Calif.

Dr. Messonnier said that the CDC has been working closely with the Food and Drug Administration to address problems with the COVID-19 test kits that were unusable because of a large number of indeterminate results. The two agencies together have determined that of the three reactions that were initially deemed necessary for a definitive COVID-19 diagnosis, just two are sufficient, so new kits that omit the problematic chemical are being manufactured and distributed.

These new kits are rapidly being made available; the goal, said Dr. Messonnier, is to have to state and local public health departments equipped with test kits by about March 7.

As local tests become available, the most updated information will be coming from state and local public health departments, she stressed, adding that the CDC would continue to update case counts on Monday, Wednesday, and Friday of each week. Procedures are being developed for the management of patients presumed to have COVID-19, where local health departments see positive tests but the mandatory CDC confirmatory test hasn’t been completed.

While new cases emerge across Europe and Asia, China’s earlier COVID-19 explosion seems to be slowing. “It’s really good news that the case counts in China are decreasing,” both for the well-being of that country’s citizens, and as a sign of the disease’s potential global effects, said Dr. Messonnier. She added that epidemiologists and mathematical modelers are parsing case fatality rates as well.

She advised health care providers and public health officials to keep abreast of changes in CDC guidance by checking frequently at https://www.cdc.gov/coronavirus/2019-ncov/index.html.

National flu activity decreased for the second consecutive week, but pediatric mortality is heading in the opposite direction, according to the Centers for Disease Control and Prevention.

MDedge News

Influenza-like illness (ILI) represented 5.5% of all visits to outpatient health care providers during the week ending Feb. 22, compared with 6.1% the previous week, the CDC’s influenza division reported Feb. 28. The ILI visit rate had reached 6.6% in early February after dropping to 5.0% in mid-January, following a rise to a season-high 7.1% in the last week of December.

Another measure of ILI activity, the percentage of laboratory specimens testing positive, also declined for the second week in a row. The rate was 26.4% for the week ending Feb. 22, which is down from the season high of 30.3% reached 2 weeks before, the influenza division said.

ILI-related deaths among children, however, are not dropping. There were 20 pediatric deaths reported during the week, more than any other single week this season. The total for 2019-2020 is now up to 125, and that “number is higher for the same time period than in every season since reporting began in 2004-05, except for the 2009 pandemic,” the CDC noted.

Hospitalization rates, which have been fairly typical in the general population, also are elevated for young adults and school-aged children, the agency said, and “rates among children 0-4 years old are now the highest CDC has on record at this point in the season, surpassing rates reported during the second wave of the 2009 H1N1 pandemic.”

An infectious disease outbreak that began in December 2019 in Wuhan (Hubei Province), China, was found to be caused by the seventh strain of coronavirus, initially called the novel (new) coronavirus. The virus was later labeled as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The disease caused by SARS-CoV-2 is named COVID-19. Until 2019, only six strains of human coronaviruses had previously been identified.

As of April 8, 2020, according to the U.S. Centers for Disease Control and Prevention, COVID-19 has been detected in at least 209 countries and has spread to every contintent except Antarctica. More than 1,469,245 people have become infected globally, and at least 86,278 have died. Based on the cases detected and tested in the United States through the U.S. public health surveillance systems, we have had 406,693 confirmed cases and 13,089 deaths.

On March 11, 2020, the World Health Organization formally declared the COVID-19 outbreak to be a pandemic.

As the number of cases increases in the United States, we hope to provide answers about some common questions regarding COVID-19. The information summarized in this article is obtained and modified from the CDC.

What are the clinical features of COVID-19?

Ranges from asymptomatic infection, a mild disease with nonspecific signs and symptoms of acute respiratory illness, to severe pneumonia with respiratory failure and septic shock.

Who is at risk for COVID-19?

Persons who have had prolonged, unprotected close contact with a patient with symptomatic, confirmed COVID-19, and those with recent travel to China, especially Hubei Province.

Who is at risk for severe disease from COVID-19?

Older adults and persons who have underlying chronic medical conditions, such as immunocompromising conditions.

How is COVID-19 spread?

Person-to-person, mainly through respiratory droplets. SARS-CoV-2 has been isolated from upper respiratory tract specimens and bronchoalveolar lavage fluid.

When is someone infectious?

Incubation period may range from 2 to 14 days. Detection of viral RNA does not necessarily mean that infectious virus is present, as it may be detectable in the upper or lower respiratory tract for weeks after illness onset.

Can someone who has been quarantined for COVID-19 spread the illness to others?

For COVID-19, the period of quarantine is 14 days from the last date of exposure, because 14 days is the longest incubation period seen for similar coronaviruses. Someone who has been released from COVID-19 quarantine is not considered a risk for spreading the virus to others because they have not developed illness during the incubation period.

Can a person test negative and later test positive for COVID-19?

Yes. In the early stages of infection, it is possible the virus will not be detected.

Do patients with confirmed or suspected COVID-19 need to be admitted to the hospital?

Not all patients with COVID-19 require hospital admission. Patients whose clinical presentation warrants inpatient clinical management for supportive medical care should be admitted to the hospital under appropriate isolation precautions. The decision to monitor these patients in the inpatient or outpatient setting should be made on a case-by-case basis.

What should you do if you suspect a patient for COVID-19?

Immediately notify both infection control personnel at your health care facility and your local or state health department. State health departments that have identified a person under investigation (PUI) should immediately contact CDC’s Emergency Operations Center (EOC) at 770-488-7100 and complete a COVID-19 PUI case investigation form.

CDC’s EOC will assist local/state health departments to collect, store, and ship specimens appropriately to CDC, including during after-hours or on weekends/holidays.
 

What type of isolation is needed for COVID-19?

Airborne Infection Isolation Room (AIIR) using Standard, Contact, and Airborne Precautions with eye protection.

How should health care personnel protect themselves when evaluating a patient who may have COVID-19?

Standard Precautions, Contact Precautions, Airborne Precautions, and use eye protection (e.g., goggles or a face shield).

What face mask do health care workers wear for respiratory protection?

A fit-tested NIOSH-certified disposable N95 filtering facepiece respirator should be worn before entry into the patient room or care area. Disposable respirators should be removed and discarded after exiting the patient’s room or care area and closing the door. Perform hand hygiene after discarding the respirator.

If reusable respirators (e.g., powered air purifying respirator/PAPR) are used, they must be cleaned and disinfected according to manufacturer’s reprocessing instructions prior to re-use.
 

What should you tell the patient if COVID-19 is suspected or confirmed?

Patients with suspected or confirmed COVID-19 should be asked to wear a surgical mask as soon as they are identified, to prevent spread to others.

Should any diagnostic or therapeutic interventions be withheld because of concerns about the transmission of COVID-19?

No.

How do you test a patient for SARS-CoV-2, the virus that causes COVID-19?

At this time, diagnostic testing for COVID-19 can be conducted only at CDC.

The CDC recommends collecting and testing multiple clinical specimens from different sites, including two specimen types – lower respiratory and upper respiratory (nasopharyngeal and oropharyngeal aspirates or washes, nasopharyngeal and oropharyngeal swabs, bronchioalveolar lavage, tracheal aspirates, sputum, and serum) using a real-time reverse transcription PCR (rRT-PCR) assay for SARS-CoV-2. Specimens should be collected as soon as possible once a PUI is identified regardless of the time of symptom onset. Turnaround time for the PCR assay testing is about 24-48 hours.

Will existing respiratory virus panels detect SARS-CoV-2, the virus that causes COVID-19?

No.

How is COVID-19 treated?

Symptomatic management. Corticosteroids are not routinely recommended for viral pneumonia or acute respiratory distress syndrome and should be avoided unless they are indicated for another reason (e.g., COPD exacerbation, refractory septic shock following Surviving Sepsis Campaign Guidelines). There are currently no antiviral drugs licensed by the U.S. Food and Drug Administration to treat COVID-19.
 

What is considered ‘close contact’ for health care exposures?

Being within approximately 6 feet (2 meters), of a person with COVID-19 for a prolonged period of time (such as caring for or visiting the patient, or sitting within 6 feet of the patient in a health care waiting area or room); or having unprotected direct contact with infectious secretions or excretions of the patient (e.g., being coughed on, touching used tissues with a bare hand). However, until more is known about transmission risks, it would be reasonable to consider anything longer than a brief (e.g., less than 1-2 minutes) exposure as prolonged.

What happens if the health care personnel (HCP) are exposed to confirmed COVID-19 patients? What’s the protocol for HCP exposed to persons under investigation (PUI) if test results are delayed beyond 48-72 hours?

Management is similar in both these scenarios. CDC categorized exposures as high, medium, low, and no identifiable risk. High- and medium-risk exposures are managed similarly with active monitoring for COVID-19 until 14 days after last potential exposure and exclude from work for 14 days after last exposure. Active monitoring means that the state or local public health authority assumes responsibility for establishing regular communication with potentially exposed people to assess for the presence of fever or respiratory symptoms (e.g., cough, shortness of breath, sore throat). For HCP with high- or medium-risk exposures, CDC recommends this communication occurs at least once each day. For full details, please see www.cdc.gov/coronavirus/2019-ncov/hcp/guidance-risk-assesment-hcp.html.

Should postexposure prophylaxis be used for people who may have been exposed to COVID-19?

None available.

COVID-19 test results are negative in a symptomatic patient you suspected of COVID-19? What does it mean?

A negative test result for a sample collected while a person has symptoms likely means that the COVID-19 virus is not causing their current illness.

What if your hospital does not have an Airborne Infection Isolation Room (AIIR) for COVID-19 patients?

Transfer the patient to a facility that has an available AIIR. If a transfer is impractical or not medically appropriate, the patient should be cared for in a single-person room and the door should be kept closed. The room should ideally not have an exhaust that is recirculated within the building without high-efficiency particulate air (HEPA) filtration. Health care personnel should still use gloves, gown, respiratory and eye protection and follow all other recommended infection prevention and control practices when caring for these patients.
 

What if your hospital does not have enough Airborne Infection Isolation Rooms (AIIR) for COVID-19 patients?

Prioritize patients for AIIR who are symptomatic with severe illness (e.g., those requiring ventilator support).

When can patients with confirmed COVID-19 be discharged from the hospital?

Patients can be discharged from the health care facility whenever clinically indicated. Isolation should be maintained at home if the patient returns home before the time period recommended for discontinuation of hospital transmission-based precautions.

Considerations to discontinue transmission-based precautions include all of the following:

• Resolution of fever, without the use of antipyretic medication.
• Improvement in illness signs and symptoms.
• Negative rRT-PCR results from at least two consecutive sets of paired nasopharyngeal and throat swabs specimens collected at least 24 hours apart (total of four negative specimens – two nasopharyngeal and two throat) from a patient with COVID-19 are needed before discontinuing transmission-based precautions.

Should people be concerned about pets or other animals and COVID-19?

To date, CDC has not received any reports of pets or other animals becoming sick with COVID-19.

Should patients avoid contact with pets or other animals if they are sick with COVID-19?

Patients should restrict contact with pets and other animals while they are sick with COVID-19, just like they would around other people.

Does CDC recommend the use of face masks in the community to prevent COVID-19?

CDC does not recommend that people who are well wear a face mask to protect themselves from respiratory illnesses, including COVID-19. A face mask should be used by people who have COVID-19 and are showing symptoms to protect others from the risk of getting infected.

Should medical waste or general waste from health care facilities treating PUIs and patients with confirmed COVID-19 be handled any differently or need any additional disinfection?

No. CDC’s guidance states that management of laundry, food service utensils, and medical waste should be performed in accordance with routine procedures.

Can people who recover from COVID-19 be infected again?

Unknown. The immune response to COVID-19 is not yet understood.

What is the mortality rate of COVID-19, and how does it compare to the mortality rate of influenza (flu)?

The average 10-year mortality rate for flu, using CDC data, is found to be around 0.1%. Even though this percentage appears to be small, influenza is estimated to be responsible for 30,000 to 40,000 deaths annually in the U.S.

According to statistics released by the Chinese Center for Disease Control and Prevention on Feb. 17, the mortality rate of COVID-19 is estimated to be around 2.3%. This calculation was based on cases reported through Feb. 11, and calcuated by dividing the number of coronavirus-related deaths at the time (1,023) by the number of confirmed cases (44,672) of COVID-19 infection. However, this report has its limitations, since Chinese officials have a vague way of defining who has COVID-19 infection.

The World Health Organization (WHO) currently estimates the mortality rate for COVID-19 to be between 2% and 4%.

Should postexposure prophylaxis be used for people who may have been exposed to COVID-19?

None available.

COVID-19 test results are negative in a symptomatic patient you suspected of COVID-19? What does it mean?

A negative test result for a sample collected while a person has symptoms likely means that the COVID-19 virus is not causing their current illness.

What if your hospital does not have an Airborne Infection Isolation Room (AIIR) for COVID-19 patients?

Transfer the patient to a facility that has an available AIIR. If a transfer is impractical or not medically appropriate, the patient should be cared for in a single-person room and the door should be kept closed. The room should ideally not have an exhaust that is recirculated within the building without high-efficiency particulate air (HEPA) filtration. Health care personnel should still use gloves, gown, respiratory and eye protection and follow all other recommended infection prevention and control practices when caring for these patients.
 

What if your hospital does not have enough Airborne Infection Isolation Rooms (AIIR) for COVID-19 patients?

Prioritize patients for AIIR who are symptomatic with severe illness (e.g., those requiring ventilator support).

When can patients with confirmed COVID-19 be discharged from the hospital?

Patients can be discharged from the health care facility whenever clinically indicated. Isolation should be maintained at home if the patient returns home before the time period recommended for discontinuation of hospital transmission-based precautions.

Considerations to discontinue transmission-based precautions include all of the following:

• Resolution of fever, without the use of antipyretic medication.
• Improvement in illness signs and symptoms.
• Negative rRT-PCR results from at least two consecutive sets of paired nasopharyngeal and throat swabs specimens collected at least 24 hours apart (total of four negative specimens – two nasopharyngeal and two throat) from a patient with COVID-19 are needed before discontinuing transmission-based precautions.

Should people be concerned about pets or other animals and COVID-19?

To date, CDC has not received any reports of pets or other animals becoming sick with COVID-19.

Should patients avoid contact with pets or other animals if they are sick with COVID-19?

Patients should restrict contact with pets and other animals while they are sick with COVID-19, just like they would around other people.

Does CDC recommend the use of face masks in the community to prevent COVID-19?

CDC does not recommend that people who are well wear a face mask to protect themselves from respiratory illnesses, including COVID-19. A face mask should be used by people who have COVID-19 and are showing symptoms to protect others from the risk of getting infected.

Should medical waste or general waste from health care facilities treating PUIs and patients with confirmed COVID-19 be handled any differently or need any additional disinfection?

No. CDC’s guidance states that management of laundry, food service utensils, and medical waste should be performed in accordance with routine procedures.

Can people who recover from COVID-19 be infected again?

Unknown. The immune response to COVID-19 is not yet understood.

What is the mortality rate of COVID-19, and how does it compare to the mortality rate of influenza (flu)?

The average 10-year mortality rate for flu, using CDC data, is found to be around 0.1%. Even though this percentage appears to be small, influenza is estimated to be responsible for 30,000 to 40,000 deaths annually in the U.S.

According to statistics released by the Chinese Center for Disease Control and Prevention on Feb. 17, the mortality rate of COVID-19 is estimated to be around 2.3%. This calculation was based on cases reported through Feb. 11, and calcuated by dividing the number of coronavirus-related deaths at the time (1,023) by the number of confirmed cases (44,672) of COVID-19 infection. However, this report has its limitations, since Chinese officials have a vague way of defining who has COVID-19 infection.

The World Health Organization (WHO) currently estimates the mortality rate for COVID-19 to be between 2% and 4%.
