Pulmonary artery denervation (PADN) provides persistent and clinically significant hemodynamic improvements in patients with persistent chronic thromboembolic hypertension (CTEPH) after pulmonary endarterectomy (PEA), according to a randomized, sham-controlled trial.

“PADN in patients with CTEPH after PEA was safe and effective,” according to an investigating team led by Alexander Romanov, MD, PhD.

The mean reduction in pulmonary vascular resistance (PVR) was 258 dyn/sec per cm^–5 for those randomized to PADN versus 149 dyn/sec per cm^–5 (P = .001) for those randomized to the sham procedure, according to the newly published findings.

For the 6-minute walk test (6MWT), the mean distance was 470 m for the experimental group versus 399 m (P = .03) for the controls.

Several secondary endpoints measuring hemodynamics also favored PADN relative to the sham procedure at 12 months. This included the relative increase in tricuspid annular systolic excursion (P = .03) and the increase in the right ventricular fraction area (P < .001).

A total of 50 patients with residual CTEPH for at least 6 months after PEA despite medical therapy were enrolled and randomized. Entry criteria included a mean pulmonary artery pressure (PAP) of 25 mm Hg or greater or PVR greater than 400 dyn/sec per cm^–5 on right heart catheterization. Patients with comorbidities associated with a life expectancy of less than 1 year were excluded.

Those randomized to the sham group were treated with riociguat over the course of follow-up. This therapy was not offered to patients in the PADN group, but all patients were blinded to the procedure and told that riociguat might or might not be administered.

Following the procedure, participating clinicians, who were also blinded to the procedure, were instructed to provide standard therapies for heart failure, such beta-blockers, diuretics, or digoxin, as needed. All patients were placed on an oral anticoagulant.

At 12 months the mean PAP (26 vs. 35 mm Hg; P < .001) and the mean systolic PAP (46 vs. 54 mm Hg; P = .01) were significantly lower in the PADN group versus those who underwent a sham procedure.

About 52% of the PADN group versus 12% of the sham group were classified as responders by the definition of a PVR reduction of at least 150 dyn/sec per cm^–5 and 6MWT improvement of at least 20%, compared with baseline, reported Dr. Romanov, of the E. Meshalkin National Medical Research Center, ministry of health, Novosibirsk, Russia, and coinvestigators.

Of the three deaths caused by heart failure over the course of follow-up, two occurred in the sham group. Of the eight hospitalizations for heart failure, seven (29% of the sham group) occurred among controls versus one in those treated with PADN (4% of this group; P = .049).

There was one groin hematoma at the puncture site in each group. Both resolved without any consequences prior to hospital discharge. There were no other significant procedure-related complications in either group.

Larger multicenter trials are needed to confirm these findings, according to both the trial investigators and Marius M. Hoeper, MD, who is charge of the pulmonary hypertension program at the Hannover (Germany) Medical School.

In an editorial that accompanied publication of these findings, Dr. Hoeper identified the small sample size of this study as one of its limitations, but he said the results are consistent with several other small studies associating pulmonary artery denervation with benefit in pulmonary hypertension.

“It appears as if we are currently witnessing the emergence of a new treatment option for various forms of pulmonary hypertension,” Dr. Hoeper wrote. In his critique of the study, he suggested that it would have been “more informative” if both groups were on background riociguat, but the data from this and other studies so far indicates that ablation to achieve denervation “is safe and feasible.”

The PADN technique used in this study might be relevant to the results. Dr. Hoeper noted that the investigators employed catheter tip–based electroanatomic mapping with a novel remote navigation system with three-dimensional imaging of the right ventricle and central pulmonary arteries.

“Apparently, this approach minimizes radiation exposure and provides precise location of ablation sites,” Dr. Hoeper observed. However, he called for direct comparisons of this tool to the guidance systems used in other studies.

In an interview, Dr. Hoeper acknowledged that it is not yet clear that a large-scale trial of pulmonary artery denervation for the indication evaluated in this study is coming. He noted several strategies in CTEPH are widely used without trials confirming a reduction in clinical events.

“Balloon pulmonary angioplasty for CTEPH has become an established treatment around the world without any randomized, controlled trial and without demonstration of improved outcomes. A couple of well-conducted observational trials might be sufficient to convince physicians to introduce PADN as well,” he said. If such studies associated PADN with “improvements in hemodynamics, exercise capacity, and patient-reported outcomes, it might be sufficient.”

Currently, Dr. Hoeper is most concerned about obtaining further evidence of safety, which he characterized as a “major issue.”

If a multicenter trial is conducted “the primary endpoint should be focused on clinical events,” according to Dr. Romanov, who was asked to comment on the next steps in validating PADN for the treatment of CTEPH-associated pulmonary hypertension persisting after endarterectomy.

“The mortality rate during 1-year long-term follow-up is not so high, but heart failure progression is a problem. So in my view, the primary endpoint should be a composite of death and heart failure hospitalization,” he said. He called for follow-up duration of 2-3 years.

Jonathan Steinberg, MD, director of cardiac clinical trials and education, Summit Medical Group, Montclair, N.J., also called a trial with hard endpoints, such as death, the ideal.

In the meantime, hemodynamic and functional measures “are still quite valuable and move the ball forward for this intervention,” he said in an interview. Senior author of this trial and principle investigator of the recent ERADICATE-AF trial, which evaluated renal denervation in preventing recurrence of atrial fibrillation (JAMA. 2020;323:248-55), Dr. Steinberg predicted, “I do indeed suspect we will see trials that are more accomplishable [than a large-scale, randomized, controlled trial] in the not too distant future.”

Dr. Romanov received funding from Biosense Webster. Dr. Hoeper has received fees for lectures and/or consultations from Acceleron, Actelion, Bayer, Janssen, Merck Sharp & Dohme, and Pfizer.

Pulmonary rehabilitation reduces the likelihood that patients with chronic obstructive pulmonary disease (COPD) will be readmitted to the hospital in the year after discharge by 33%, new research shows, but few patients participate in those programs.

In fact, in a retrospective cohort of 197,376 patients from 4446 hospitals, only 1.5% of patients initiated pulmonary rehabilitation in the 90 days after hospital discharge.

“This is a striking finding,” said Mihaela Stefan, PhD, from the University of Massachusetts Medical School–Baystate in Springfield. “Our study demonstrates that we need to increase access to rehabilitation to reduce the risk of readmissions.”

Not enough patients are initiating rehabilitation, but the onus is not only on them; the system is failing them. “We wanted to understand how much pulmonary rehabilitation lowers the readmission rate,” Stefan told Medscape Medical News.

So she and her colleagues examined the records of patients who were hospitalized for COPD in 2014 to see whether they had begun rehabilitation in the 90 days after discharge and whether they were readmitted to the hospital in the subsequent 12 months.

Patients who were unlikely to initiate pulmonary rehabilitation — such as those with dementia or metastatic cancer and those discharged to hospice care or a nursing home — were excluded from the analysis, Stefan said during her presentation at the study results at the virtual American Thoracic Society (ATS) 2020 International Conference.

The risk analysis was complex because many patients died before the year was out, and “a patient who dies has no risk of being readmitted,” she explained. Selection bias was also a factor because patients who do pulmonary rehab tend to be in better shape.

The researchers used propensity score matching and Anderson–Gill models of cumulative rehospitalizations or death at 1 year with time-varying exposure to pulmonary rehabilitation to account for clustering of individual events and adjust for covariates. “It was a complicated risk analysis,” she said.

In the year after discharge, 130,660 patients (66%) were readmitted to the hospital. The rate of rehospitalization was lower for those who initiated rehabilitation than for those who did not (59% vs 66%), as was the mean number of readmissions per patient (1.4 vs 1.8).

Rehabilitation was associated with a lower risk for readmission or death (hazard ratio, 0.67; 95% CI, 0.66 - 0.69).

“We know the referral rates are low and that pulmonary rehabilitation is effective in clinical trials,” said Stefan, and now “we see that pulmonary rehabilitation is effective when you look at patients in real life.”

From a provider perspective, “we need to make sure that hospitals get more money for pulmonary rehabilitation. Cardiac rehabilitation is paid for,” she explained. "But pulmonary rehab is not a lucrative business. I don›t know why the CMS pays more for cardiac."

A rehabilitation program generally consists of 36 sessions, held two or three times a week, and many patients can’t afford that on their own, she noted. Transportation is another huge issue.

A recent study in which semi-structured interviews were conducted with 15 COPD patients showed that the main barriers to enrollment in a pulmonary rehabilitation program are lack of awareness, family obligations, transportation, and lack of motivation, said Stefan, who was involved in that research.

Telehealth rehabilitation programs might become more available in the near future, given the COVID pandemic. But “currently, Medicare doesn’t pay for telerehab,” she said. Virtual sessions might attract more patients, but lack of computer access and training could present another barrier for some.

PAH rehab

Uptake for pulmonary rehabilitation is as low for patients with pulmonary arterial hypertension (PAH) as it is for those with COPD, according to another study presented at the virtual ATS meeting.

An examination of the electronic health records of 111,356 veterans who experienced incident PAH from 2010 to 2016 showed that only 1,737 (1.6%) followed through on pulmonary rehabilitation.

“Exercise therapy is safe and effective at improving outcomes,” lead author Thomas Cascino, MD, from the University of Michigan in Ann Arbor, said in an ATS press release. “Recognizing that it is being underutilized is a necessary first step in working toward increasing patient access to rehab.

His group is currently working on a trial for home-based rehabilitation “using wearable technology as a means to expand access for people unable to come to center-based rehab for a variety of reasons,” he explained.

“The goal of all our treatments is to help people feel better and live longer,” Cascino added.

Stefan and Cascino have disclosed no relevant financial relationships.

Following invasive ventilation for severe hypercapnic respiratory failure, patients with chronic obstructive pulmonary disease had similar levels of treatment failure if they received high-flow nasal cannula oxygen therapy or noninvasive ventilation, recent research in Critical Care has suggested.

However, for patients with COPD weaned off invasive ventilation, high-flow nasal cannula (HFNC) oxygen therapy was “more comfortable and better tolerated,” compared with noninvasive ventilation (NIV). In addition, “airway care interventions and the incidence of nasofacial skin breakdown associated with HFNC were significantly lower than in NIV,” according to Dingyu Tan of the Clinical Medical College of Yangzhou (China) University, Northern Jiangsu People’s Hospital, and colleagues. “HFNC appears to be an effective means of respiratory support for COPD patients extubated after severe hypercapnic respiratory failure,” they said.

The investigators screened patients with COPD and hypercapnic respiratory failure for enrollment, including those who met Global Initiative for Obstructive Lung Disease (GOLD) criteria, were 85 years old or younger and caring for themselves, had bronchopulmonary infection–induced respiratory failure, and had achieved pulmonary infection control criteria. Exclusion criteria were:

• Patients under age 18 years.
• Presence of oral or facial trauma.
• Poor sputum excretion ability.
• Hemodynamic instability that would contraindicate use of NIV.
• Poor cough during PIC window.
• Poor short-term prognosis.
• Failure of the heart, brain, liver or kidney.
• Patients who could not consent to treatment.

Patients were determined to have failed treatment if they returned to invasive mechanical ventilation or switched from one treatment to another (HFNC to NIV or NIV to HFNC). Investigators also performed an arterial blood gas analysis, recorded the number of duration of airway care interventions, and monitored vital signs at 1 hour, 24 hours, and 48 hours after extubation as secondary analyses.

Overall, 44 patients randomized to receive HFNC and 42 patients randomized for NIV were available for analysis. The investigators found 22.7% of patients in the HFNC group and 28.6% in the NIV group experienced treatment failure (risk difference, –5.8%; 95% confidence interval, −23.8 to 12.4%; P = .535), with patients in the HFNC group experiencing a significantly lower level of treatment intolerance, compared with patients in the NIV group (risk difference, ­–50.0%; 95% CI, −74.6 to −12.9%; P = .015). There were no significant differences between either group regarding intubation (−0.65%; 95% CI, −16.01 to 14.46%), while rate of switching treatments was lower in the HFNC group but not significant (−5.2%; 95% CI, −19.82 to 9.05%).

Patients in both the HFNC and NIV groups had faster mean respiratory rates 1 hour after extubation (P < .050). After 24 hours, the NIV group had higher-than-baseline respiratory rates, compared with the HFNC group, which had returned to normal (20 vs. 24.5 breaths per minute; P < .050). Both groups had returned to baseline by 48 hours after extubation. At 1 hour after extubation, patients in the HFNC group had lower PaO₂/FiO₂ (P < .050) and pH values (P < .050), and higher PaCO₂ values (P less than .050), compared with baseline. There were no statistically significant differences in PaO₂/FiO₂, pH, and PaCO₂ values in either group at 24 hours or 48 hours after extubation.

Daily airway care interventions were significantly higher on average in the NIV group, compared with the HFNC group (7 vs. 6; P = .0006), and the HFNC group also had significantly better comfort scores (7 vs. 5; P < .001) as measured by a modified visual analog scale, as well as incidence of nasal and facial skin breakdown (0 vs. 9.6%; P = .027), compared with the NIV group.
 

Results difficult to apply to North American patients

David L. Bowton, MD, FCCP, a professor specializing in critical care at Wake Forest University, Winston-Salem, N.C., said in an interview the results of this trial may not be applicable for patients with infection-related respiratory failure and COPD in North America “due to the differences in common weaning practices between North America and China.”

For example, the trial used the pulmonary infection control (PIC) window criteria for extubation, which requires a significant decrease in radiographic infiltrates, improvement in quality and quantity of sputum, normalizing of leukocyte count, a synchronized intermittent mandatory ventilation (SIMV) rate of 10-12 breaths per minute, and pressure support less than 10-12 cm/H₂O (Int J Chron Obstruct Pulmon Dis. 2017;12:1255-67).

“The process used to achieve these measures is not standardized. In North America, daily awakening and screening for spontaneous breathing trials would be usual, but this was not reported in the current trial,” he explained.

Differences in patient population also make the application of the results difficult, Dr. Bowton said. “Only 60% of the patients had spirometrically confirmed COPD and fewer than half were on at least dual inhaled therapy prior to hospitalization with only one-third taking beta agonists or anticholinergic agents,” he noted. “The cause of respiratory failure was infectious, requiring an infiltrate on chest radiograph; thus, patients with hypercarbic respiratory failure without a new infiltrate were excluded from the study. On average, patients were hypercarbic, yet alkalemic at the time of extubation; the PaCO₂ and pH at the time of intubation were not reported.

“This study suggests that in some patients with COPD and respiratory failure requiring invasive mechanical ventilation, HFO [high-flow oxygen] may be better tolerated and equally effective as NIPPV [noninvasive positive-pressure ventilation] at mitigating the need for reintubation following extubation. In this patient population where hypoxemia prior to extubation was not severe, the mechanisms by which HFO is beneficial remain speculative,” he said.

This study was funded by the Rui E special fund for emergency medicine research and the Yangzhou Science and Technology Development Plan. The authors report no relevant conflicts of interest. Dr. Bowton reports no relevant conflicts of interest.

Following invasive ventilation for severe hypercapnic respiratory failure, patients with chronic obstructive pulmonary disease had similar levels of treatment failure if they received high-flow nasal cannula oxygen therapy or noninvasive ventilation, recent research in Critical Care has suggested.

However, for patients with COPD weaned off invasive ventilation, high-flow nasal cannula (HFNC) oxygen therapy was “more comfortable and better tolerated,” compared with noninvasive ventilation (NIV). In addition, “airway care interventions and the incidence of nasofacial skin breakdown associated with HFNC were significantly lower than in NIV,” according to Dingyu Tan of the Clinical Medical College of Yangzhou (China) University, Northern Jiangsu People’s Hospital, and colleagues. “HFNC appears to be an effective means of respiratory support for COPD patients extubated after severe hypercapnic respiratory failure,” they said.

The investigators screened patients with COPD and hypercapnic respiratory failure for enrollment, including those who met Global Initiative for Obstructive Lung Disease (GOLD) criteria, were 85 years old or younger and caring for themselves, had bronchopulmonary infection–induced respiratory failure, and had achieved pulmonary infection control criteria. Exclusion criteria were:

• Patients under age 18 years.
• Presence of oral or facial trauma.
• Poor sputum excretion ability.
• Hemodynamic instability that would contraindicate use of NIV.
• Poor cough during PIC window.
• Poor short-term prognosis.
• Failure of the heart, brain, liver or kidney.
• Patients who could not consent to treatment.

Patients were determined to have failed treatment if they returned to invasive mechanical ventilation or switched from one treatment to another (HFNC to NIV or NIV to HFNC). Investigators also performed an arterial blood gas analysis, recorded the number of duration of airway care interventions, and monitored vital signs at 1 hour, 24 hours, and 48 hours after extubation as secondary analyses.

The investigators found 22.7% of patients in the HFNC group and 28.6% in the NIV group experienced treatment failure (risk difference, –5.8%; 95% confidence interval, −23.8 to 12.4%; P = .535), with patients in the HFNC group experiencing a significantly lower level of treatment intolerance, compared with patients in the NIV group (risk difference, ­–50.0%; 95% CI, −74.6 to −12.9%; P = .015).

In a large California health care plan, among patients with COVID-19, men aged 60 years and younger had a much higher risk of dying within 3 weeks of diagnosis if they had severe obesity as opposed to being of normal weight, independently of other risk factors.

The research shows that “obesity plays a profound role in risk for death from COVID-19, particularly in male patients and younger populations,” reported Sara Y. Tartof, PhD, MPH, Kaiser Permanente Southern California, Pasadena, Calif., and coauthors.

The data “highlight the leading role of severe obesity over correlated risk factors, providing a target for early intervention,” they concluded in an article published online Aug. 12 in Annals of Internal Medicine.

This work adds to nearly 300 articles that have shown that severe obesity is associated with an increased risk for morbidity and mortality from COVID-19.

In an accompanying editorial, David A. Kass, MD, said: “Consistency of this new study and prior research should put to rest the contention that obesity is common in severe COVID-19 because it is common in the population.”

Rather, these findings show that “obesity is an important independent risk factor for serious COVID-19 disease,” he pointed out.

On the basis of this evidence, “arguably the hardest question to answer is: What is to be done?” wondered Kass, of Johns Hopkins University, Baltimore.

Although data consistently show that a body mass index >35 kg/m² is predictive of major health risks, “weight reduction at that level of obesity is difficult and certainly is not achieved rapidly,” Dr. Kass stressed.

“Therefore ... social distancing; altering behaviors to reduce viral exposure and transmission, such as wearing masks; and instituting policies and health care approaches that recognize the potential effects of obesity should be implemented,” he emphasized. “These actions should help and are certainly doable.”

Similarly, Dr. Tartof and colleagues said their “findings also reveal the distressing collision of two pandemics: COVID-19 and obesity.

“As COVID-19 continues to spread unabated, we must focus our immediate efforts on containing the crisis at hand,” they urged.

However, the findings also “underscore the need for future collective efforts to combat the equally devastating, and potentially synergistic, force of the obesity epidemic.”
 

COVID-19 pandemic collides with obesity epidemic

Previous studies of obesity and COVID-19 were small, did not adjust for multiple confounders, or did not include nonhospitalized patients, Dr. Tartof and coauthors wrote.

Their study included 6,916 members of the Kaiser Permanente Southern California health care plan who were diagnosed with COVID-19 from Feb. 13 to May 2, 2020.

The researchers calculated the risk for death at 21 days after a COVID-19 diagnosis; findings were corrected for age, sex, race/ethnicity, smoking, myocardial infarction, heart failure, peripheral vascular disease, cerebrovascular disease, chronic pulmonary disease, renal disease, metastatic tumor or malignancy, other immune disease, hyperlipidemia, hypertension, asthma, organ transplant, and diabetes status.

On the basis of BMI, the patients were classified as being underweight, of normal weight, overweight, or as having class 1, 2, or 3 obesity. BMI of 18.5 to 24 kg/m² is defined as normal weight.

Class 3 obesity, also called severe obesity, included moderately severe obesity (BMI, 40-44 kg/m²) and extremely severe obesity (≥45 kg/m²).

A little more than half of the patients were women (55%), and more than 50% were Hispanic (54%).

A total of 206 patients (3%) died within 21 days of being diagnosed with COVID-19; of these, 67% had been hospitalized, and 43% had been intubated.

Overall, the COVID-19 patients with moderately severe or extremely severe obesity had a 2.7-fold and 4.2-fold increased risk for death, respectively, within 3 weeks compared with patients of normal weight.

Patients in the other BMI categories did not have a significantly higher risk of dying during follow-up.

However, each decade of increasing age after age 40 was associated with a stepwise increased risk for death within 3 weeks of the COVID-19 diagnosis.
 

Risk stratified by age and sex

Further analysis showed that, “most strikingly,” among patients aged 60 and younger, those with moderately severe obesity and extremely severe obesity had significant 17-fold and 12-fold higher risks of dying during follow-up, respectively, compared with patients of normal weight, the researchers reported.

In patients older than 60, moderately severe obesity did not confer a significant increased risk for imminent death from COVID-19; extremely severe obesity conferred a smaller, threefold increased risk for this.

“Our finding that severe obesity, particularly among younger patients, eclipses the mortality risk posed by other obesity-related conditions, such as history of myocardial infarction (MI), diabetes, hypertension, or hyperlipidemia, suggests a significant pathophysiologic link between excess adiposity and severe COVID-19 illness,” the researchers noted.

This independent increased risk for death with severe obesity was seen in men but not in women.

Men with moderately severe and extremely severe obesity had significant 4.8-fold and 10-fold higher risks of dying within 3 weeks, respectively, compared with men of normal weight.

“That the risks are higher in younger patients is probably not because obesity is particularly damaging in this age group; it is more likely that other serious comorbidities that evolve later in life take over as dominant risk factors,” Dr. Kass suggested in his editorial.

“That males are particularly affected may reflect their greater visceral adiposity over females, given that this fat is notably proinflammatory and contributes to metabolic and vascular disease,” he added.

“As a cardiologist who studies heart failure,” Dr. Kass wrote, “I am struck by how many of the mechanisms that are mentioned in reviews of obesity risk and heart disease are also mentioned in reviews of obesity and COVID-19.”

The study was funded by Roche-Genentech. Kass has disclosed no relevant financial relationships. Disclosures of the authors are listed in the article.

“Our finding that severe obesity, particularly among younger patients, eclipses the mortality risk posed by other obesity-related conditions, such as history of myocardial infarction (MI), diabetes, hypertension, or hyperlipidemia, suggests a significant pathophysiologic link between excess adiposity and severe COVID-19 illness,” the researchers noted.

This independent increased risk for death with severe obesity was seen in men but not in women.

Men with moderately severe and extremely severe obesity had significant 4.8-fold and 10-fold higher risks of dying within 3 weeks, respectively, compared with men of normal weight.

“That the risks are higher in younger patients is probably not because obesity is particularly damaging in this age group; it is more likely that other serious comorbidities that evolve later in life take over as dominant risk factors,” Dr. Kass suggested in his editorial.

“That males are particularly affected may reflect their greater visceral adiposity over females, given that this fat is notably proinflammatory and contributes to metabolic and vascular disease,” he added.

“As a cardiologist who studies heart failure,” Dr. Kass wrote, “I am struck by how many of the mechanisms that are mentioned in reviews of obesity risk and heart disease are also mentioned in reviews of obesity and COVID-19.”

The study was funded by Roche-Genentech. Kass has disclosed no relevant financial relationships. Disclosures of the authors are listed in the article.

All intermediate-risk pulmonary embolism is not the same, Victor F. Tapson, MD, declared at HM20 Virtual, hosted by the Society of Hospital Medicine.

The best current guidelines on the management of acute pulmonary embolism (PE) recommend a risk stratification strategy that involves further subdivision of intermediate-risk PE into intermediate to low or intermediate to high risk. This additional classification is worthwhile because it has important treatment implications.

Patients with intermediate- to low-risk PE, along with those who have truly low-risk PE, require anticoagulation only. In contrast, patients with intermediate- to high-risk PE are at increased risk of decompensation. They have a much higher in-hospital mortality than those with intermediate- to low-risk PE. So hospitalists may want to consult their hospitals’ PE response team (PERT), if there is one, or whoever on staff is involved in helping make decisions about the appropriateness of more aggressive interventions, such as catheter-directed thrombolysis or catheter-directed clot extraction, said Dr. Tapson, director of the venous thromboembolism and pulmonary vascular disease research program at Cedars-Sinai Medical Center in Los Angeles.

“We don’t have evidence of any real proven mortality difference yet in the intermediate-high risk PE group by being more aggressive. I think if the right patients were studied we could see a mortality difference. But one thing I’ve noted is that by being more aggressive – in a cautious manner, in selected patients – we clearly shorten the hospital stay by doing catheter-directed therapy in some of these folks. It saves money,” he observed.

Once the diagnosis of PE is confirmed, the first priority is to get anticoagulation started in all patients with an acceptable bleeding risk, since there is convincing evidence that anticoagulation reduces mortality in PE. The 2019 European Society of Cardiology guidelines recommend a direct-acting oral anticoagulant over warfarin on the basis of persuasive evidence of lower risk of major bleeding coupled with equal or better effectiveness in preventing recurrent PE.

Dr. Tapson said it’s worthwhile for hospitalists to take a close look at these European guidelines (Eur Respir J. 2019 Oct 9. doi: 10.1183/13993003.01647-2019).

“I think our Europeans friends did a really nice job with those guidelines. They’re great guidelines, better than many of the others out there. I think they’re very, very usable,” he said. “I took part in the ACCP [American College of Chest Physicians] guidelines for years. I think they’re very rigorous in terms of the evidence base, but because they’re so rigorous there’s just tons of 2C recommendations, which are basically suggestions. The ESC guidelines are more robust.”
 

Risk stratification

Once anticoagulation is on board, the next task is risk stratification to determine the need for more aggressive therapy. A high-risk PE is best defined hemodynamically as one causing a systolic blood pressure below 90 mm Hg for at least 15 minutes. The term “high risk” is increasingly replacing “massive” PE, because the size of the clot doesn’t necessarily correlate with its hemodynamic impact.

An intermediate-risk PE is marked by a simplified Pulmonary Embolism Severity Index (sPESI) score of 1 or more, right ventricular dysfunction on echocardiography or CT angiography, or an elevated cardiac troponin level.

The sPESI is a validated, user-friendly tool that grants 1 point each for age over 80, background cardiopulmonary disease, a systolic blood pressure below 100 mm Hg, cancer, a heart rate of 110 bpm or more, and an oxygen saturation level below 90%.

“All you really need to know about a patient’s sPESI score is: Is it more than zero?” he explained.

Indeed, patients with an sPESI score of 0 have a 30-day mortality of 1%. With a score of 1 or more, however, that risk jumps to 10.9%.

No scoring system is 100% accurate, though, and Dr. Tapson emphasized that clinician gestalt plays an important role in PE risk stratification. In terms of clinical indicators of risk, he pays special attention to heart rate.

“I think if I had to pick the one thing that drives my decision the most about whether someone needs more aggressive therapy than anticoagulation, it’s probably heart rate,” he said. “If the heart rate is 70, the patient is probably very stable. Of course, that might not hold up in a patient with conduction problems or who is on a beta blocker, but in general if I see someone who looks good, has a relatively small PE, and a low heart rate, it makes me feel much better. If the heart rate is 130 or 120, I’m much more concerned.”

Both the European guidelines and the PERT Consortium guidelines on the diagnosis, treatment, and follow-up of acute PE (Clin Appl Thromb Hemost. 2019 Jun 17. doi: 10.1177/1076029619853037), which Dr. Tapson coauthored, recommend substratifying intermediate-risk PE into intermediate to low or intermediate to high risk. It’s a straightforward matter: If a patient has either right ventricular dysfunction on imaging or an elevated cardiac troponin, that’s an intermediate- to low-risk PE warranting anticoagulation only. On the other hand, if both right ventricular dysfunction and an elevated troponin are present, the patient has an intermediate- to high-risk PE. Since this distinction translates to a difference in outcome, a consultation with PERT or an experienced PE interventionalist is in order for the intermediate- to high-risk PE, he said.

Dr. Tapson reported receiving research funding from Bayer, Bristol-Myers Squibb, Janssen, BiO2, EKOS/BTG, and Daiichi. He is also a consultant to Janssen and BiO2, and on speakers’ bureaus for EKOS/BTG and Janssen.

August was National Immunization Awareness Month. ... just in time to address the precipitous drop in immunization delivered during the early months of the pandemic.

FatCamera/Getty Images

In May, the Centers for Disease Control and Prevention reported substantial reductions in vaccine doses ordered through the Vaccines for Children program after the declaration of national emergency because of COVID-19 on March 13. Approximately 2.5 million fewer doses of routine, noninfluenza vaccines were administered between Jan. 6 and April 2020, compared with a similar period last year (MMWR Morb Mortal Wkly Rep. 2020 May 15;69[19]:591-3). Declines in immunization rates were echoed by states and municipalities across the United States. Last month, the health system in which I work reported 40,000 children behind on at least one vaccine.

We all know that, when immunization rates drop, outbreaks of vaccine-preventable diseases follow. In order to avert another public health crisis, we need action as well as awareness to catch up with childhood immunizations, and that is going to take more than a single month.
 

Identify patients who’ve missed vaccinations

Simply being open and ready to vaccinate is not enough. The Centers for Disease Control and Prevention urges providers to identify patients who have missed vaccines, and call them to schedule in-person visits. Proactively let parents know about strategies implemented in your office to ensure a safe environment.

Pediatricians are accustomed to an influx of patients in the summer, as parents make sure their children have all of the vaccines required for school attendance. As noted in a Washington Post article from Aug. 4, 2020, schools have traditionally served as a backstop for immunization rates. But as many school districts opt to take education online this fall, the implications for vaccine requirements are unclear. District of Columbia public schools continue to require immunization for virtual school attendance, but it is not clear how easily this can be enforced. To read about how other school districts have chosen to address – or not address – immunization requirements for school, visit the the Immunization Action Coalition’s Repository of Resources for Maintaining Immunization during the COVID-19 Pandemic. The repository links to international, national, and state-level policies and guidance and advocacy materials, including talking points, webinars, press releases, media articles from around the United States and social media posts, as well as telehealth resources.
 

Get some inspiration to talk about vaccination

Need a little inspiration for talking to parents about vaccines? Check out the CDC’s #HowIRecommend video series. These are short videos, most under a minute in length, that explain the importance of vaccination, how to effectively address questions from parents about vaccine safety, and how clinicians routinely recommend same day vaccination to their patients. These videos are part of the CDC’s National Immunization Awareness Month (NIAM) toolkit for communication with health care professionals. A companion toolkit for communicating with parents and patients contains sample social media messages with graphics, along with educational resources to share with parents.

The “Comprehensive Vaccine Education Program – From Training to Practice,” a free online program offered by the Pediatric Infectious Diseases Society, takes a deeper dive into strategies to combat vaccine misinformation and address vaccine hesitancy. Available modules cover vaccine fundamentals, vaccine safety, clinical manifestations of vaccine-preventable diseases, and communication skills that lead to more effective conversations with patients and parents. The curriculum also includes the newest edition of The Vaccine Handbook app, a comprehensive source of practical information for vaccine providers.
 

Educate young children about vaccines

Don’t leave young children out of the conversation. Vax-Force is a children’s book that explores how vaccination works inside the human body. Dr. Vaxson the pediatrician explains how trusted doctors and scientists made Vicky the Vaccine. Her mission is to tell Willy the White Blood Cell and his Antibuddies how to find and fight bad-guy germs like measles, tetanus, and polio. The book was written by Kelsey Rowe, MD, while she was a medical student at Saint Louis University School of Medicine. Dr. Rowe, now a pediatric resident, notes, “In a world where anti-vaccination rhetoric threatens the health of our global community, this book’s mission is to teach children and adults alike that getting vaccinations is a safe, effective, and even exciting thing to do.” The book is available for purchase at https://www.vax-force.com/, and a small part of every sale is donated to Unicef USA.
 

Consider vaccination advocacy in your communities

Vaccinate Your Family, a national, nonprofit organization dedicated to protecting people of all ages from vaccine-preventable diseases, suggests that health care providers need to take an active role in raising immunization rates, not just in their own practices, but in their communities. One way to do this is to submit an opinion piece or letter to the editor to a local newspaper describing why it’s important for parents to make sure their child’s immunizations are current. Those who have never written an opinion-editorial should look at the guidance developed by Voices for Vaccines.
 

How are we doing?

Early data suggest a rebound in immunization rates in May and June, but that is unlikely to close the gap created by disruptions in health care delivery earlier in the year. Collectively, we need to set ambitious goals. Are we just trying to reach prepandemic immunization levels? In Kentucky, where I practice, only 71% of kids aged 19-45 months had received all doses of seven routinely recommended vaccines (≥4 DTaP doses, ≥3 polio doses, ≥1 MMR dose, Hib full series, ≥3 HepB doses, ≥1 varicella dose, and ≥4 PCV doses) based on 2017 National Immunization Survey data. The Healthy People 2020 target goal is 80%. Only 55% of Kentucky girls aged 13-17 years received at least one dose of HPV vaccine, and rates in boys were even lower. Flu vaccine coverage in children 6 months to 17 years also was 55%. The status quo sets the bar too low. To see how your state is doing, check out the interactive map developed by the American Academy of Pediatrics.

Are we attempting to avoid disaster or can we seize the opportunity to protect more children than ever from vaccine-preventable diseases? The latter would really be something to celebrate.

Available modules cover vaccine fundamentals, vaccine safety, clinical manifestations of vaccine-preventable diseases, and communication skills that lead to more effective conversations with patients and parents. The curriculum also includes the newest edition of The Vaccine Handbook app, a comprehensive source of practical information for vaccine providers.
 

Educate young children about vaccines

Don’t leave young children out of the conversation. Vax-Force is a children’s book that explores how vaccination works inside the human body. Dr. Vaxson the pediatrician explains how trusted doctors and scientists made Vicky the Vaccine. Her mission is to tell Willy the White Blood Cell and his Antibuddies how to find and fight bad-guy germs like measles, tetanus, and polio. The book was written by Kelsey Rowe, MD, while she was a medical student at Saint Louis University School of Medicine. Dr. Rowe, now a pediatric resident, notes, “In a world where anti-vaccination rhetoric threatens the health of our global community, this book’s mission is to teach children and adults alike that getting vaccinations is a safe, effective, and even exciting thing to do.” The book is available for purchase at https://www.vax-force.com/, and a small part of every sale is donated to Unicef USA.
 

Consider vaccination advocacy in your communities

Vaccinate Your Family, a national, nonprofit organization dedicated to protecting people of all ages from vaccine-preventable diseases, suggests that health care providers need to take an active role in raising immunization rates, not just in their own practices, but in their communities. One way to do this is to submit an opinion piece or letter to the editor to a local newspaper describing why it’s important for parents to make sure their child’s immunizations are current. Those who have never written an opinion-editorial should look at the guidance developed by Voices for Vaccines.
 

How are we doing?

Early data suggest a rebound in immunization rates in May and June, but that is unlikely to close the gap created by disruptions in health care delivery earlier in the year. Collectively, we need to set ambitious goals. Are we just trying to reach prepandemic immunization levels? In Kentucky, where I practice, only 71% of kids aged 19-45 months had received all doses of seven routinely recommended vaccines (≥4 DTaP doses, ≥3 polio doses, ≥1 MMR dose, Hib full series, ≥3 HepB doses, ≥1 varicella dose, and ≥4 PCV doses) based on 2017 National Immunization Survey data. The Healthy People 2020 target goal is 80%. Only 55% of Kentucky girls aged 13-17 years received at least one dose of HPV vaccine, and rates in boys were even lower. Flu vaccine coverage in children 6 months to 17 years also was 55%. The status quo sets the bar too low. To see how your state is doing, check out the interactive map developed by the American Academy of Pediatrics.

Are we attempting to avoid disaster or can we seize the opportunity to protect more children than ever from vaccine-preventable diseases? The latter would really be something to celebrate.

Frailty is a highly prevalent syndrome in nursing homes, occurring in at least 50% of patients.¹ The frailty phenotype has been described by Fried and colleagues as impairment in ≥ 3 of 5 domains: unintentional weight loss, self-reported exhaustion, muscle weakness, slow gait speed, and low physical activity. By this definition, frailty is highly associated with poor quality of life and mortality.^2,3

In recent years, there has been evolving evidence of a relationship between frailty and chronic systemic inflammation.^4-6 Some degree of chronic inflammation is likely inherent to the aging process and increases the risk of frailty (so-called inflammaging) but is seen to a greater degree in many pathologic conditions in nursing homes, including cancer, organ failure, and chronic infection.^4,6-8

Dysphagia also is highly prevalent in nursing homes, affecting up to 60% of patients and is a strong predictor of hospital utilization and of mortality.^9,10 Overt aspiration pneumonitis and pneumonia are perhaps the best studied sequelae, but chronic occult microaspiration also is prevalent in this population.¹¹ Just as normal systemic inflammatory changes in aging may increase vulnerability to frailty with additional illness burden, normal aging changes in swallowing function may increase vulnerability to dysphagia and to microaspiration with additional illness burden.^12,13 In older adults, important risk factors for microaspiration include not only overt dysphagia, dementia, and other neurologic illnesses, but also general debility, weakness, and immobility.¹⁴

Matsuse and colleagues have described diffuse aspiration bronchiolitis (DAB) in patients with chronic microaspiration.¹⁴ DAB often goes undiagnosed.^14-16 As in frailty, weight loss and chronic anemia may be seen, and many of these patients are bedridden.^14,17 Episodes of macroaspiration and overt lobar pneumonia also may occur.¹⁴ Lung biopsy or autopsy reveals chronic bronchiolar inflammation and sometimes pulmonary fibrosis, but to date there have been no reports suggesting chronic systemic inflammation or elevated proinflammatory cytokines.^14,15,17 We present 3 patients with progressive weight loss, functional decline, and frailty in whom chronic microaspiration likely played a significant role.

Case 1 Presentation

A 68-year-old man with a 6-year history of rapidly progressive Parkinson disease was admitted to the Haley’s Cove Community Living Center (CLC) on the James A. Haley Veterans’ Hospital campus in Tampa, Florida for long-term care. The patient’s medical history also was significant for bipolar illness and for small cell carcinoma of the lung in sustained remission.

Medications included levodopa/carbidopa 50 mg/200 mg 4 times daily, entacapone 200 mg 4 times daily, lithium carbonate 600 mg every night at bedtime, lamotrigine 150 mg daily, quetiapine 200 mg every night at bedtime, pravastatin 40 mg every night at bedtime, omeprazole 20 mg daily, tamsulosin 0.4 mg every night at bedtime, and aspirin 81 mg daily. He initially did well, but after 6 months the nursing staff began to notice the patient coughing during and after meals. Speech pathology evaluation revealed moderate oropharyngeal dysphagia, and his diet was downgraded to nectar-thickened liquids.

Over the subsequent 10 months, he became progressively weaker in physical therapy and more inactive, with about a 20-lb weight loss and mild hypoalbuminemia of 3.0 gm/dL. He had developed 3 episodes of aspiration pneumonia during this period; a repeat swallow evaluation after the last episode revealed worsened dysphagia, and his physician suggested nil per os (NPO) status and an alternative feeding route. His guardian declined placement of a percutaneous endoscopic gastrostomy (PEG) tube, he was transferred to the inpatient hospice unit, and died 2 weeks later. An autopsy was declined.

Case 2 Presentation

A 66-year-old man with a medical history of multiple traumatic brain injuries (TBIs) was admitted to the CLC for long-term care. Sequelae of the TBIs included moderate dementia, spastic paraparesis with multiple pressure injuries, a well-controlled seizure disorder, and severe oropharyngeal dysphagia with NPO status and a percutaneous endoscopic gastrostomy (PEG) tube. His medical history included TBIs and hepatitis C virus infection; medications included levetiracetam 1,000 mg twice daily, lamotrigine 25 mg twice daily, and cholecalciferol 2,000 U daily. He had multiple stage III pressure injuries and an ischial stage IV injury at the time of admission.

His 11-month stay in the CLC was characterized by progressively worsening weakness and inactivity, with a 25-lb weight loss in spite of adequate tube feeding. Serum albumin remained in the 2.0 to 2.5 gm/dL range, hemoglobin in the 7 to 9 gm/dL range without any obvious source of anemia. Most of the pressure injuries worsened during his stay in spite of aggressive wound care, and he developed a second stage IV sacral wound. A single C-reactive protein (CRP) level 2 months prior to his death was markedly elevated at 19.5 mg/dL. In spite of maintaining NPO status, he developed 3 episodes of aspiration pneumonia, all of which responded well to treatment. Ultimately, he was found pulseless and apneic and resuscitation was unsuccessful. An autopsy revealed purulent material in the small airways.

Case 3 Presentation

A 65-year-old man with a long history of paranoid schizophrenia and severe gastroesophageal reflux disease had resided in the CLC for about 10 years. Medications included risperidone microspheres 37.5 mg every 2 weeks, valproic acid 500 mg 3 times daily and 1,000 mg every night at bedtime, lansoprazole 30 mg twice daily, ranitidine 150 mg every night at bedtime, sucralfate 1,000 mg 3 times daily, simvastatin 20 mg every night at bedtime, and tamsulosin 0.4 mg every night at bedtime. He had done well for many years but developed some drooling and a modest resting tremor (but no other signs of pseudoparkinsonism) about 8 years after admission.

There had been no changes to his risperidone dosage. He also lost about 20 lb over a period of 1 year and became increasingly weak and dependent in gait, serum albumin dropped as low as 1.6 gm/dL, hemoglobin dropped to the 7 to 8 gm/dL range (without any other obvious source of anemia), and he developed a gradually worsening right-sided pleural effusion. CRP was chronically elevated at this point, in the 6 to 15 mg/dL range and as high as 17.2 mg/dL. Ultimately, he developed 3 episodes of aspiration pneumonia over a period of 2 months. Swallowing evaluation at that time revealed severe oropharyngeal dysphagia and a PEG tube was placed. Due to concerns for possible antipsychotic-induced dysphagia, risperidone was discontinued, and quetiapine 400 mg a day was substituted. He did well over the subsequent year with no further pneumonia and advancement back to a regular diet. He regained all of the lost weight and began independent ambulation. Albumin improved to the 3 gm/dL range, hemoglobin to the 12 to 13 gm/dL range, and CRP had decreased to 0.7 mg/dL. The pleural effusion (believed to have been a parapneumonic effusion) had resolved.

Discussion

All 3 patients met the Fried criteria for frailty, although there were several confounding issues.² All 3 patients lost between 20 and 25 lb; all had clearly become weaker according to nursing and rehabilitation staff (although none were formally assessed for grip strength); and all had clear declines in their activity level. Patient 3 had a clear decrement in gait speed, but patient 1 had severe gait impairment due to Parkinson disease (although his gait in therapy had clearly worsened). Patient 2 was paraparetic and unable to ambulate. There also was evidence of limited biomarkers of systemic inflammation; all 3 patients’ albumin had decreased, and patients 2 and 3 had significant decrease in hemoglobin; but these commonplace clinical biomarkers are obviously multifactorially determined. We have limited data on our patients’ CRP levels; serial levels would have been more specific for systemic inflammation but were infrequently performed on the patients.

Multimorbidity and medical complexity are more the rule than the exception in frail geriatric patients,and it is difficult to separate the role of microaspiration from other confounding conditions that might have contributed to these patients’ evolving systemic inflammation and frailty.¹⁸ It might be argued that the decline for patient 1 was related to the underlying Parkinson disease (a progressive neurologic illness in which systemic inflammation has been reported), or that the decline of patient 2 was related to the worsening pressure injuries rather than to covert microaspiration.¹⁹ However, the TBIs for patient 2 and the schizophrenia for patient 3 would not be expected to be associated with frailty or with systemic inflammation. Furthermore, the frailty symptoms of patient 3 and inflammatory biomarkers improved after the risperidone, which was likely responsible for his microaspiration, was discontinued. All 3 patients were at risk for oropharyngeal dysphagia (antipsychotic medication is clearly associated with dysphagia²⁰); patient 2 demonstrated pathologic evidence of DAB at autopsy.

There is evolving evidence that chronic systemic inflammation and immune activation are key mechanisms in the pathogenesis of frailty.^4-6 It is known that elevated serum levels of proinflammatory cytokines, including tumor necrosis factor-α, interleukin-6, and CRP are directly associated with frailty and are inversely associated with levels of albumin, hemoglobin, insulin-like growth factor-1, and several micronutrients in frail individuals.^4-7,21,22 Chronic inflammation contributes to the pathophysiology of frailty through detrimental effects on a broad range of systems, including the musculoskeletal, endocrine, and hematopoietic systems and through nutritional dysregulation.^2,4,23 These changes may lead to further deleterious effects, creating a downward spiral of worsening frailty. For example, it seems likely that our patients’ progressive weakness further compromised airway protection, creating a vicious cycle of worsening microaspiration and chronic inflammation.

Conclusions

To date, the role of chronic microaspiration and DAB in chronic systemic inflammation or in frailty has not been explored. Given the prevalence of microaspiration in nursing home residents and the devastating consequences of frailty, though, this seems to be a crucial area of investigation. It is equally crucial for long-term care staff, both providers and nursing staff, to have a heightened awareness of covert microaspiration and a low threshold for referral to speech pathology for further investigation. Staff also should be aware of the utility of the Fried criteria to improve identification of frailty in general. It is probable that covert microaspiration will prove to be an important part of the differential diagnosis of frailty.

It is equally crucial for long-term care staff, both providers and nursing staff, to have a heightened awareness of covert microaspiration and a low threshold for referral to speech pathology for further investigation. Staff also should be aware of the utility of the Fried criteria to improve identification of frailty in general. It is probable that covert microaspiration will prove to be an important part of the differential diagnosis of frailty.

Patients with sarcoidosis have an increased risk of heart failure and other adverse outcomes, including all-cause mortality, according to a decade-long nationwide study of Danish patients with the inflammatory disease.

“Although these findings are suggestive of the need for regular monitoring of cardiac manifestations in patients with sarcoidosis, it is important to emphasize that no causal relationships can be established from an observational study. Further studies are therefore needed to confirm our findings,” said first author Adelina Yafasova, MB, of Copenhagen University Hospital in Denmark, in an interview. The study was published in the Journal of the American College of Cardiology.

To determine the long-term risk of cardiac outcomes, and beyond – including incident heart failure; a composite of implantable cardioverter-defibrillator (ICD) implantation, ventricular arrhythmias or cardiac arrest; and all-cause mortality – Dr. Yafasova and her colleagues analyzed data from all Danish residents 18 years or older who were diagnosed with sarcoidosis from 1996 to 2016. Patients with any history of cardiac events were excluded. Of the 12,883 diagnosed patients, 11,834 were matched with subjects from a nationwide background population of more than 47,000 based on age, sex, and comorbidity. The median age of both populations was 42.8 (33.1-55.8) and 54.3% were men.

Median follow-up was 8.2 years for the sarcoidosis population and 8.4 years for the background population. The absolute 10-year risk of heart failure was 3.18% (95% confidence interval, 2.83%-3.57%) for sarcoidosis patients and 1.72% (95% CI, 1.58%-1.86%) for their matched controls. The 10-year risk for the composite of ICD implantation, ventricular arrhythmias and cardiac arrest was 0.96% (95% CI, 0.77%-1.18%) for sarcoidosis patients and 0.45% (95% CI, 0.38%-0.53%) for the background population.

For all-cause mortality, the 10-year risk was 10.88% (95% CI, 10.23%-11.55%) for sarcoidosis patients and 7.43% (95% CI, 7.15%-7.72%) for the background population. In a secondary analysis that compared all-cause mortality between the 364 sarcoidosis patients who developed heart failure and the 1,456 patients with heart failure without a history of sarcoidosis, the sarcoidosis group had a 35% higher rate than the nonsarcoidosis group (adjusted hazard ratio 1.35; 95% CI, 1.10-1.64).

“It’s not necessarily surprising that sarcoidosis patients would have a higher rate of heart failure,” said Melissa A. Lyle, MD, of the Mayo Clinic in Jacksonville, Fla., in an interview. “But the key takeaway is that sarcoidosis was associated with a higher rate of all-cause mortality compared to patients with heart failure and no sarcoidosis. That was more of a surprise.”

“There’s been some discrepancy in previous studies describing the cardiovascular outcomes in sarcoidosis,” Dr. Lyle added, “so I think this study provides excellent information while also highlighting the need for additional large-scale studies. We need to have further data on cardiovascular outcomes, which will allow us to refine the consensus statements and guidelines for management and the diagnosis of cardiac sarcoidosis.”

Dr. Lyle and Leslie T. Cooper Jr., MD, also of the Mayo Clinic, extrapolated on those thoughts in an editorial that accompanied the study. In it, the two authors praised the size and lengthy follow-up of the study, while noting its limitations. Specifically, they stressed that the study’s Danish population “may not be representative of other general populations” because of notable differences in ethnicity, age, and comorbidities.

That said, they reinforced that the study did feature “important takeaways” and that its findings emphasize the “need for monitoring for cardiac manifestations in patients with systemic sarcoidosis.”

In addition to the limitations noted in the editorial, the study’s authors acknowledged that the observational nature limited its “assessment of cause-effect relationships” and that the diagnosis codes for sarcoidosis had not been validated in the Danish National Patient Registry.

The authors of both the study and the editorial reported no conflicts of interest.

The cumulative number of new COVID-19 cases among children in the United States jumped by 90% during a recent 4-week period, according to a report that confirms children are not immune to the coronavirus.

“In areas with rapid community spread, it’s likely that more children will also be infected, and these data show that,” Sally Goza, MD, president of the American Academy of Pediatrics, said in a written statement. “I urge people to wear cloth face coverings and be diligent in social distancing and hand-washing. It is up to us to make the difference, community by community.”

The joint report from the AAP and the Children’s Hospital Association draws on data from state and local health departments in 49 states, New York City, the District of Columbia, Puerto Rico, and Guam.

The cumulative number of COVID-19 cases in children as of Aug. 6, 2020, was 380,174, and that number is 90% higher – an increase of 179,990 cases – than the total on July 9, just 4 weeks earlier, the two organizations said in the report.

The total cases for children represented 9.1% of all 4,159,947 million U.S. cases as of Aug. 6, compared with just 2.0% as of April 16, and 27 states out of 47 with available data now report that over 10% of their cases were children, with Wyoming the highest at 16.5% and New Jersey the lowest at 2.9%, the report data show.

Alabama has a higher percentage of 22.5%, but the state has been reporting cases in individuals aged 0-24 years as child cases since May 7. The report’s findings are somewhat limited by differences in reporting among the states and by “gaps in the data they are reporting [that affect] how the data can be interpreted,” the AAP said in its statement.

The cumulative number of cases per 100,000 children has risen from 13.3 in mid-April, when the total number was 9,259 cases, to 500.7 per 100,000 as of Aug. 6, and there are now 21 states, along with the District of Columbia, reporting a rate of over 500 cases per 100,000 children. Arizona has the highest rate at 1,206.4, followed by South Carolina (1,074.4) and Tennessee (1,050.8), the AAP and the CHA said.

In New York City, the early epicenter of the pandemic, the 390.5 cases per 100,000 children have been reported, and in New Jersey, which joined New York in the initial surge of cases, the number is 269.5. As of Aug. 6, Hawaii had the fewest cases of any state at 91.2 per 100,000, according to the report.

Children continue to represent a very low proportion of COVID-19 deaths, “but as case counts rise across the board, that is likely to impact more children with severe illness as well,” Sean O’Leary, MD, MPH, vice chair of the AAP’s committee on infectious diseases, said in the AAP statement.

It is possible that “some of the increase in numbers of cases in children could be due to more testing. Early in the pandemic, testing only occurred for the sickest individuals. Now that there is more testing capacity … the numbers reflect a broader slice of the population, including children who may have mild or few symptoms,” the AAP suggested.

Big data scientists and health-care experts have tried preparing physicians and patients for the arrival of telemedicine for years. Health tracking applications are on our smartphones. Compact ambulatory devices diagnose hypertension and atrial fibrillation.  Advanced imaging modalities make the stethoscope more of a neck accessory than a practical tool. Despite these efficient technologic advancements, the idea of making the sacred in-person office visit remote and through a screen appealed to few. In fact, prior to the COVID-19 pandemic, only 15% of medical practices offered telehealth services and 8% of Americans joined in remote visits annually (Mann DM et al. J Am Med Inform Assoc. 2019 Feb 1;26[2]:106-114).

When the COVID-19 pandemic hit New York City and admissions for hypoxemic respiratory failure skyrocketed, ED and in-person clinic visits for other acute and chronic conditions plummeted. Prior to clinics officially closing their doors, doctors in New York City asked their patients to reserve office visits for emergency issues only ,with most patients willingly staying home to avoid exposure to the virus. Suddenly, after years of disinterest in adopting telehealth, hospitals and clinics were catapulted into a full-on need for this technology. Overnight, our division’s secretaries and medical assistants became IT support staff.  We all learned together what worked, what didn’t work, and how to adapt our workflow to meet everyone’s needs.

Previously, longstanding issues with accessibility and reimbursement presented barriers to widespread adoption of telemedicine. Once the pandemic hit, though, many regulatory changes were quickly made to accommodate telehealth. 

Three such changes are worth highlighting (Centers for Medicare and Medicaid Services. COVID-19 emergency declaration blanket waivers for health care providers. March 30, 2020). 

First, patient privacy rules became more lenient.  Prior to the pandemic, HIPAA mandated that both doctor and patient use embedded video interfaces with high levels of security.  Now, health-care providers can use commonplace video chat applications such as FaceTime, Google Hangouts, Zoom, or Skype to provide telehealth without risk of penalty for HIPAA noncompliance.  When connectivity concerns arose with our EMR’s embedded telehealth application, a quick transition to one of these platforms mitigated patient and provider frustration. 

Second, prior to the pandemic, some private insurance providers reimbursed for televisits, but there were stipulations on how the visit could be conducted. Now, many of the commercial insurers plus Medicare and Medicaid in New York State reimburse the same amount for televisits as in-person visits (fee-for-service rate).  Reimbursement rates of audio-only encounters were increased.   If these changes are continued postpandemic, it will have an expansive impact on the future of an outpatient practice.  

Third, restrictive government regulations relaxed with regard to telehealth deployment.  Gone are the demands on providers and patients to be physically face-to-face.  Many colleagues worked from home, safely social distancing. 

Even though remote medical visits were a crucial part of flattening the curve during the peak of the pandemic in New York City, the telehealth experience is not without flaws. 

An informal survey of providers in our own division garnered diverse and spirited viewpoints about seeing patients remotely.  Instead of using a stethoscope to pick up a subtle finding, telehealth visits require the use of our eyes to scan a patient’s home environment for insights explaining their chronic cough (Where is the mold? Where is the water damage? Where is the bird?).  We use our ears to hear the intonation of our patient’s voice to know when he or she is concerned, anxious, or are at their baselines.  We would implore patients to put on their pulse oximeter and perform activities of daily living and/or exertion. On multiple occasions, patients would perform their own, unsolicited walks about their home to show us what they could and couldn’t do, where they place their concentrators, and where they are likely to trip over oxygen tubing. We learned to depend on them to reach the conclusion that they were at their normal state of health.

For straight-forward encounters with existing patients, most of our colleagues appreciated the simplicity and efficiency of telemedicine. But when it came to new patients, some colleagues struggled with whether they should see them for the first time over video. Universally, providers felt feelings of inadequacy without an in-person examination and review of diagnostic information. 

Along those lines, many of our colleagues worried about their ability to perform the most fundamental role of a physician over the phone/internet for all patients: building trust with a patient.  Eye contact, the physical exam, and verbal and nonverbal communication that engenders confidence and displays empathy remain a challenge.  Multiple colleagues commented on the difficulty of communicating a new horrible diagnosis over a spotty internet connection.  Others expressed concern about the inability to review chest imaging in-person with patients as this often enhances patient comprehension and relieves anxiety about diagnostic possibilities. 

Providers also noted that telehealth implementation is not the same for all individuals. Just as COVID-19 disproportionately affects the most vulnerable populations (NYC Health. COVID-19: data. Accessed July 1, 2020. https://www1.nyc.gov/site/doh/covid/covid-19-data.page), practicing telehealth has uncovered more ways in which racial/ethnic minorities, low income communities, and older patients are at a disadvantage (Garg S, et al. MMWR Morb Mortal Wkly Rep. 2020;69[15]:458). The relatively quick transition to telemedicine revealed that many of our patients don’t have emails or home computers to connect with online platforms. Similarly, some do not have smart phones with internet capabilities. Many do not speak English and cannot partake in video visits since translators are not yet embedded into the EMR’s video system. Elderly patients were frequently very anxious with telemedicine because of unfamiliarity with the technology, and many preferred a phone conversation.  Thus, while more fortunate patients get to use a video interface and its association with higher patient understanding and satisfaction, our most vulnerable populations are often denied the same access to such care (Voils CI et al. J Genet Couns. 2018;27[2]:339).  

Telemedicine will continue to have a significant impact on the future of health care long after the COVID-19 pandemic abates.  There will be growing pains, refinement of technology, improvements in policy, and an ongoing general evolution of the system. Patients and providers will grow together as its utilization continues. We suspect patient surveys about their attitudes and preferences for telemedicine will be as varied as the providers surveyed here.  A recent survey of 1000 patients about their telehealth experiences during the pandemic reported that over 75% were very or completely satisfied with their virtual care experiences and over 50% indicated they would be willing to switch providers to have virtual visits on a regular basis (Patient Perspectives on Virtual Care Report, Accessed July 7, 2020, https://www.kyruus.com/2020-virtual-care-report).

One hopes that with time and on-going feedback, the fundamental purpose of the physician-patient relationship can be maintained and both sides can still appreciate the conveniences and power of telehealth technology.

Third, restrictive government regulations relaxed with regard to telehealth deployment.  Gone are the demands on providers and patients to be physically face-to-face.  Many colleagues worked from home, safely social distancing. 

Even though remote medical visits were a crucial part of flattening the curve during the peak of the pandemic in New York City, the telehealth experience is not without flaws. 

An informal survey of providers in our own division garnered diverse and spirited viewpoints about seeing patients remotely.  Instead of using a stethoscope to pick up a subtle finding, telehealth visits require the use of our eyes to scan a patient’s home environment for insights explaining their chronic cough (Where is the mold? Where is the water damage? Where is the bird?).  We use our ears to hear the intonation of our patient’s voice to know when he or she is concerned, anxious, or are at their baselines.  We would implore patients to put on their pulse oximeter and perform activities of daily living and/or exertion. On multiple occasions, patients would perform their own, unsolicited walks about their home to show us what they could and couldn’t do, where they place their concentrators, and where they are likely to trip over oxygen tubing. We learned to depend on them to reach the conclusion that they were at their normal state of health.

For straight-forward encounters with existing patients, most of our colleagues appreciated the simplicity and efficiency of telemedicine. But when it came to new patients, some colleagues struggled with whether they should see them for the first time over video. Universally, providers felt feelings of inadequacy without an in-person examination and review of diagnostic information. 

Along those lines, many of our colleagues worried about their ability to perform the most fundamental role of a physician over the phone/internet for all patients: building trust with a patient.  Eye contact, the physical exam, and verbal and nonverbal communication that engenders confidence and displays empathy remain a challenge.  Multiple colleagues commented on the difficulty of communicating a new horrible diagnosis over a spotty internet connection.  Others expressed concern about the inability to review chest imaging in-person with patients as this often enhances patient comprehension and relieves anxiety about diagnostic possibilities. 

Providers also noted that telehealth implementation is not the same for all individuals. Just as COVID-19 disproportionately affects the most vulnerable populations (NYC Health. COVID-19: data. Accessed July 1, 2020. https://www1.nyc.gov/site/doh/covid/covid-19-data.page), practicing telehealth has uncovered more ways in which racial/ethnic minorities, low income communities, and older patients are at a disadvantage (Garg S, et al. MMWR Morb Mortal Wkly Rep. 2020;69[15]:458). The relatively quick transition to telemedicine revealed that many of our patients don’t have emails or home computers to connect with online platforms. Similarly, some do not have smart phones with internet capabilities. Many do not speak English and cannot partake in video visits since translators are not yet embedded into the EMR’s video system. Elderly patients were frequently very anxious with telemedicine because of unfamiliarity with the technology, and many preferred a phone conversation.  Thus, while more fortunate patients get to use a video interface and its association with higher patient understanding and satisfaction, our most vulnerable populations are often denied the same access to such care (Voils CI et al. J Genet Couns. 2018;27[2]:339).  

Telemedicine will continue to have a significant impact on the future of health care long after the COVID-19 pandemic abates.  There will be growing pains, refinement of technology, improvements in policy, and an ongoing general evolution of the system. Patients and providers will grow together as its utilization continues. We suspect patient surveys about their attitudes and preferences for telemedicine will be as varied as the providers surveyed here.  A recent survey of 1000 patients about their telehealth experiences during the pandemic reported that over 75% were very or completely satisfied with their virtual care experiences and over 50% indicated they would be willing to switch providers to have virtual visits on a regular basis (Patient Perspectives on Virtual Care Report, Accessed July 7, 2020, https://www.kyruus.com/2020-virtual-care-report).

One hopes that with time and on-going feedback, the fundamental purpose of the physician-patient relationship can be maintained and both sides can still appreciate the conveniences and power of telehealth technology.

Big data scientists and health-care experts have tried preparing physicians and patients for the arrival of telemedicine for years. Health tracking applications are on our smartphones. Compact ambulatory devices diagnose hypertension and atrial fibrillation.  Advanced imaging modalities make the stethoscope more of a neck accessory than a practical tool. Despite these efficient technologic advancements, the idea of making the sacred in-person office visit remote and through a screen appealed to few. In fact, prior to the COVID-19 pandemic, only 15% of medical practices offered telehealth services and 8% of Americans joined in remote visits annually (Mann DM et al. J Am Med Inform Assoc. 2019 Feb 1;26[2]:106-114).

When the COVID-19 pandemic hit New York City and admissions for hypoxemic respiratory failure skyrocketed, ED and in-person clinic visits for other acute and chronic conditions plummeted. Prior to clinics officially closing their doors, doctors in New York City asked their patients to reserve office visits for emergency issues only ,with most patients willingly staying home to avoid exposure to the virus. Suddenly, after years of disinterest in adopting telehealth, hospitals and clinics were catapulted into a full-on need for this technology. Overnight, our division’s secretaries and medical assistants became IT support staff.  We all learned together what worked, what didn’t work, and how to adapt our workflow to meet everyone’s needs.

Previously, longstanding issues with accessibility and reimbursement presented barriers to widespread adoption of telemedicine. Once the pandemic hit, though, many regulatory changes were quickly made to accommodate telehealth. 

Three such changes are worth highlighting (Centers for Medicare and Medicaid Services. COVID-19 emergency declaration blanket waivers for health care providers. March 30, 2020). 

First, patient privacy rules became more lenient.  Prior to the pandemic, HIPAA mandated that both doctor and patient use embedded video interfaces with high levels of security.  Now, health-care providers can use commonplace video chat applications such as FaceTime, Google Hangouts, Zoom, or Skype to provide telehealth without risk of penalty for HIPAA noncompliance.  When connectivity concerns arose with our EMR’s embedded telehealth application, a quick transition to one of these platforms mitigated patient and provider frustration. 

Second, prior to the pandemic, some private insurance providers reimbursed for televisits, but there were stipulations on how the visit could be conducted. Now, many of the commercial insurers plus Medicare and Medicaid in New York State reimburse the same amount for televisits as in-person visits (fee-for-service rate).  Reimbursement rates of audio-only encounters were increased.   If these changes are continued postpandemic, it will have an expansive impact on the future of an outpatient practice.
