COPD

Insomnia is “highly prevalent” in veterans with chronic pulmonary obstructive disease and is significantly associated with greater COPD-related health care utilization, according to an analysis of national Veterans Health Administration data.

“The study highlights the importance of exploring potential sleep disturbances and disorders in this population and suggests that a targeted treatment for insomnia may help to improve COPD outcomes in veterans with COPD and insomnia,” said Faith Luyster, PhD, assistant professor at the University of Pittsburgh, in an interview after the virtual annual meeting of the Associated Professional Sleep Societies, where she presented the findings.

Dr. Luyster and coinvestigators used an administrative database from the Veterans Affairs Corporate Data Warehouse to identify more than 1.5 million patients with COPD who used VHA services over a 6-year period (fiscal years 2011-2017). Insomnia was defined by ICD-9/10 diagnostic codes and/or a sedative-hypnotic prescription for at least 30 doses during any of these years.

Insomnia with COPD was prevalent in this sample of veterans at 37.3%. Compared with veterans without comorbid insomnia, those who had both COPD and insomnia (575,539 of the total 1,542,642) were older (69 vs. 64 years), more likely to be female (6.3% vs. 3.7%), more likely to be Black (14% vs. 11%) and more likely to be a current smoker (46.1% vs. 35.5%).

Those with both COPD and insomnia were also more likely to have a service-connected disability rating of 50% of greater; use supplemental oxygen; be divorced, widowed, or separated; have a higher body mass index; or have other medical or psychiatric conditions – in particular obstructive sleep apnea (39% vs. 7%), depression (21% vs. 5%), and PTSD (33% vs. 3%).

P values were < .001 for all of these demographic and clinical variables, Dr. Luyster reported at the meeting.

Comorbid insomnia clearly impacted health care utilization, she said. Veterans with insomnia in addition to COPD had more outpatient and ED visits (10.5 vs 6.9, and 1.6 vs. 1.4, respectively) and more hospitalizations (2.2 vs. 1.8) with a primary diagnostic code for COPD or COPD exacerbation (P < .001).

A negative binomial regression analysis (P < .001) showed that “even after controlling for demographic and other medical conditions, COPD patients with insomnia had greater rates of health care utilization relative to COPD patients without insomnia,” Dr. Luyster said in the interview.

Prior studies have suggested that disturbed sleep is a predictor of poorer longitudinal outcomes in COPD, even after controlling for COPD severity, but have not looked specifically at insomnia, she said.

Commenting on the study Octavian C. Ioachimescu, MD, PhD, of Emory University, Atlanta, and the Atlanta VA Medical Center in Decatur, said the criteria used to define insomnia – unadjudicated ICD diagnoses as well as sedative-hypnotic prescriptions – may explain part of the reported prevalence of insomnia. Even so, the findings add to existing literature demonstrating that COPD and insomnia are both common disorders among VHA patients, and that their frequent coexistence “could have adverse consequences on the overall health, functional status, long-term outcomes, and quality of life of these patients.”

Questions of causation are yet to be answered, he said. “Is it that uncontrolled or severe airflow obstruction causing frequent nocturnal arousals, dyspnea, orthopnea, overuse of inhaled sympathomimetics and heightened anxiety leads to insomnia? Or is it that insomnia – possibly in a cluster with other affective disorders such as depression, anxiety disorders, or PTSD – elicits more frequent or more severe symptoms of shortness of breath in those with smoking-induced airway and parenchymal lung disease, making the latter diagnosis more overt than in others?

“My bet is on a bidirectional causal relationship,” said Dr. Ioachimescu, an editorial board advisor of CHEST Physician.

“Regardless of the etiology [of insomnia in veterans with COPD],” Dr. Luyster said, “it’s important that [insomnia] be addressed and treated appropriately, whether that be through pharmacological treatment, or probably more ideally through [cognitive behavioral therapy] for insomnia.”

The study did not control for COPD severity, she said, because of the difficulty of extracting this data from the VA Corporate Data Warehouse. The study was funded by the VA Competitive Career Development Fund.Dr. Luyster reported that she had no disclosures. Dr. Ioachimescu also said he had no relevant disclosures.

Patients with chronic obstructive pulmonary disease who also had certain interstitial lung abnormalities experienced more exacerbations and reduced lung function than those without such abnormalities, findings from a retrospective study has shown.

Interstitial lung abnormalities (ILA) are considered precursor lesions of interstitial lung disease and previous studies suggested an association with poor outcomes among chronic obstructive pulmonary disease (COPD) patients, but data on long-term clinical relevance are limited, wrote Tae Seung Lee, MD, of Seoul (South Korea) National University Hospital, and colleagues.

In a study published in Chest, the researchers reviewed data from 363 COPD patients including 44 with equivocal ILA and 103 with definite ILA. Overall, the ILA patients were older and had poorer lung function than non-ILA patients. Patients received chest CT scan and longitudinal pulmonary function tests between January 2013 and December 2018.

Over an average follow-up period of 5.4 years, patients with ILA experienced significantly more acute COPD exacerbations than did those without ILA (adjusted odds ratio, 2.03). The percentages of frequent exacerbators among patients with no ILA, equivocal ILA, and definite ILA were 8.3%, 15.9%, and 20.4%, respectively.

“Acute exacerbation is an important event during the clinical course of COPD, because it is associated with temporary or persistent reductions in lung function, lower quality of life, hospitalization, and mortality,” the researchers noted.

In a multivariate analysis, the annual decline in lung function (FEV₁) was –35.7 in patients with equivocal ILA, compared with –28.0 in patients with no ILA and –15.9 in those with definite ILA.

“This may be due to the distribution of the spirometric stages in each group, and to the resulting changes in lung function,” the researchers wrote. In this study, “the equivocal ILA group had a significantly lower baseline FEV₁ than the other groups. In our study population, the lower the spirometric stage, the faster the annual decline in FEV₁, consistent with the results of a prior prospective study of a COPD cohort.”

The findings were limited by several factors including the retrospective design and relatively small number of ILA patients, as well as the limited evaluation of ILA and potential for selection bias, the researchers noted. However, the result support the impact of ILA on exacerbations and accelerated decline in lung function in COPD patients.

The study received no outside funding. The researchers had no financial conflicts to disclose.

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.

A study has shown a strong link between sleeping disturbances and depression in patients with chronic obstructive pulmonary disease.

Adults with clinically stable COPD who reported sleep problems were significantly more likely to report depression or anxiety, poor self-efficacy, and poor health-related quality of life, compared with those not reporting sleep problems, according to the findings from a study of 245 patients.

Sleep problems are common in patients with COPD and have been associated with poor COPD-related outcomes, wrote Sang Hee Lee, MD, of Wonkwang University Sanbon Hospital, Gunpo-si, South Korea, and colleagues.

“However, there is a lack of research on factors associated with sleep disturbance in patients with COPD,” they wrote.

In a prospective, multicenter, cross-sectional study published in the Clinical Respiratory Journal, the researchers enrolled 245 adults with COPD who completed the COPD and Asthma Impact Scale (CASIS) to determine sleep impairment. The CASIS was developed to measure sleep-related problems associated with respiratory disease, and scored on a scale of 1-100, with higher scores indicating greater sleep impairment. The average CASIS score was 40.9. The average age of the patients was 67 years, and 92% were men.

Patients’ health-related quality of life, anxiety/depression, and self-efficacy were assessed using the St. George’s Respiratory Questionnaire (SGRQ), the 36-item Short-Form Health Survey (SF-36), Hospital Anxiety and Depression Scale (HADS), and the COPD Self-Efficacy Scale (CSES). The average scores on these measures were 36.0 for the SGRQ; 48.1 and 50.6, respectively, for the physical and mental components of the SF-36; 3.8 and 6.4, respectively, for the HADS-A and HADS-D measures of anxiety and depression; and 3.3 on the CSES.

Worse sleep in these patients was associated with worse scores on measures of mood. In a multivariate analysis, higher scores on all four measures of health-related quality of life were significantly associated with higher CASIS scores (P = .006 for SGRQ; P = .037 for SF-36, P < .001 for HADS, and P = .010 for CSES).

Although the CASIS did not allow for measurement of symptom severity and did not include many items related to breathing problems, the test “shows good internal consistency, test-retest reproducibility, and construct validity according to previous studies,” the researchers wrote. “The CASIS may be a good tool for evaluating sleep disturbances in COPD patients, and further study is needed,” they added.

The study findings were limited by several factors including the cross-sectional study design, lack of data on obstructive sleep apnea, and lack of information on specific treatments such as at-home oxygen use or high-dose steroid use, the researchers noted. However, the results were strengthened by the use of a disease-specific sleep measure, and the study is the first known to include self-efficacy in relation to sleep quality in COPD patients, they reported.

The results highlight the association between depression, poor quality of life, and self-efficacy in relation to poor sleep, and suggest that “Sleep quality could be improved by enhancing HRQL and self-efficacy,” the researchers said. “Screening for mood disorder in patients with COPD is also needed,” they concluded.

The study was supported by the Basic Science Research Program of the National Research Foundation of Korea (NRF) funded by the Ministry of Education, Science and Technology. The researchers had no financial conflicts to disclose.

Extended use of corticosteroids for chronic inflammatory conditions puts patients at risk for serious adverse events (AEs), including cardiovascular disease, osteoporosis, cataracts, and diabetes. Now, a growing body of evidence suggests that even short bursts of these drugs are associated with serious risks.

Most recently, a population-based study of more than 2.6 million people found that taking corticosteroids for 14 days or less was associated with a substantially greater risk for gastrointestinal (GI) bleeding, sepsis, and heart failure, particularly within the first 30 days after therapy.

In the study, Tsung-Chieh Yao, MD, PhD, a professor in the division of allergy, asthma, and rheumatology in the department of pediatrics at Chang Gung Memorial Hospital in Taoyuan, Taiwan, and colleagues used a self-controlled case series to analyze data from Taiwan’s National Health Insurance Research Database of medical claims. They compared patients’ conditions in the period from 5 to 90 days before treatment to conditions from the periods from 5 to 30 days and from 31 to 90 days after therapy.

With a median duration of 3 days of treatment, the incidence rate ratios (IRRs) were 1.80 (95% confidence interval, 1.75-1.84) for GI bleeding, 1.99 (95% CI, 1.70-2.32) for sepsis, and 2.37 (95% CI, 2.13-2.63) for heart failure.

Given the findings, physicians should weigh the benefits against the risks of rare but potentially serious consequences of these anti-inflammatory drugs, according to the authors.

“After initiating patients on oral steroid bursts, physicians should be on the lookout for these severe adverse events, particularly within the first month after initiation of steroid therapy,” Dr. Yao said in an interview.

The findings were published online July 6 in Annals of Internal Medicine.

Of the 15,859,129 adult Asians in the Taiwanese database, the study included 2,623,327 adults aged 20-64 years who received single steroid bursts (14 days or less) between Jan. 1, 2013, and Dec. 31, 2015.

Almost 60% of the indications were for skin disorders, such as eczema and urticaria, and for respiratory tract infections, such as sinusitis and acute pharyngitis. Among specialties, dermatology, otolaryngology, family practice, internal medicine, and pediatrics accounted for 88% of prescriptions.

“Our findings are important for physicians and guideline developers because short-term use of oral corticosteroids is common and the real-world safety of this approach remains unclear,” the authors wrote. They acknowledged that the database did not provide information on such potential confounders as disease severity and lifestyle factors, nor did it include children and vulnerable individuals, which may limit the generalizability of the results.

The findings echo those of a 2017 cohort study conducted by researchers at the University of Michigan in Ann Arbor. That study, by Akbar K. Waljee, MD, assistant professor of gastroenterology, University of Michigan, Ann Arbor, and colleagues, included data on more than 1.5 million privately insured U.S. adults. The researchers included somewhat longer steroid bursts of up to 30 days’ duration and found that use of the drugs was associated with a greater than fivefold increased risk for sepsis, a more than threefold increased risk for venous thromboembolism, and a nearly twofold increased risk for fracture within 30 days of starting treatment.

Furthermore, the elevated risk persisted at prednisone-equivalent doses of less than 20 mg/d (IRR, 4.02 for sepsis, 3.61 for venous thromboembolism, and 1.83 for fracture; all P < .001).

The U.S. study also found that during the 3-year period from 2012 to 2014, more than 20% of patients were prescribed short-term oral corticosteroids.

“Both studies indicate that these short-term regimens are more common in the real world than was previously thought and are not risk free,” Dr. Yao said.

Recognition that corticosteroids are associated with adverse events has been building for decades, according to the authors of an editorial that accompanies the new study.

“However, we commonly use short corticosteroid ‘bursts’ for minor ailments despite a lack of evidence for meaningful benefit. We are now learning that bursts as short as 3 days may increase risk for serious AEs, even in young and healthy people,” wrote editorialists Beth I. Wallace, MD, of the Center for Clinical Management Research at the VA Ann Arbor Healthcare System and the Institute for Healthcare Policy and Innovation at Michigan Medicine, Ann Arbor, and Dr. Waljee, who led the 2017 study.

Dr. Wallace and Dr. Waljee drew parallels between corticosteroid bursts and other short-term regimens, such as of antibiotics and opiates, in which prescriber preference and sometimes patient pressure play a role. “All of these treatments have well-defined indications but can cause net harm when used. We can thus conceive of a corticosteroid stewardship model of targeted interventions that aims to reduce inappropriate prescribing,” they wrote.

In an interview, Dr. Wallace, a rheumatologist who prescribes oral steroids fairly frequently, noted that the Taiwan study is the first to investigate steroid bursts. “Up till now, these very short courses have flown under the radar. Clinicians very commonly prescribe short courses to help relieve symptoms of self-limited conditions like bronchitis, and we assume that because the exposure duration is short, the risks are low, especially for patients who are otherwise healthy.”

She warned that the data in the current study indicate that these short bursts – even at the lower end of the 1- to 2-week courses American physicians prescribe most often – carry small but real increases in risk for serious AEs. “And these increases were seen in young, healthy people, not just in people with preexisting conditions,” she said. “So, we might need to start thinking harder about how we are prescribing even these very short courses of steroids and try to use steroids only when their meaningful benefits really outweigh the risk.”

She noted that a patient with a chronic inflammatory condition such as rheumatoid arthritis may benefit substantially from short-term steroids to treat a disease flare. In that specific case, the benefits of short-term steroids may outweigh the risks, Dr. Wallace said.

But not everyone thinks a new strategy is needed. For Whitney A. High, MD, associate professor of dermatology and pathology at the University of Colorado at Denver, Aurora, the overprescribing of short-term corticosteroids is not a problem, and dermatologists are already exercising caution.

“I only prescribe these drugs short term to, at a guess, about 1 in 40 patients and only when a patient is miserable and quality of life is being seriously affected,” he said in an interview. “And that’s something that can’t be measured in a database study like the one from Taiwan but only in a risk-benefit analysis,” he said.

Furthermore, dermatologists have other drugs and technologies in their armamentarium, including topical steroids with occlusion or with wet wraps, phototherapy, phosphodiesterase inhibitors, calcipotriene, methotrexate and other immunosuppressive agents, and biologics. “In fact, many of these agents are specifically referred to as steroid-sparing,” Dr. High said.

Nor does he experience much pressure from patients to prescribe these drugs. “While occasionally I may encounter a patient who places pressure on me for oral steroids, it’s probably not nearly as frequently as providers in other fields are pressured to prescribe antibiotics or narcotics,” he said.

According to the Taiwanese researchers, the next step is to conduct more studies, including clinical trials, to determine optimal use of corticosteroids by monitoring adverse events. In the meantime, for practitioners such as Dr. Wallace and Dr. High, there is ample evidence from several recent studies of the harms of short-term corticosteroids, whereas the benefits for patients with self-limiting conditions remain uncertain. “This and other studies like it quite appropriately remind providers to avoid oral steroids when they’re not necessary and to seek alternatives where possible,” Dr. High said.

Extended use of corticosteroids for chronic inflammatory conditions puts patients at risk for serious adverse events (AEs), including cardiovascular disease, osteoporosis, cataracts, and diabetes. Now, a growing body of evidence suggests that even short bursts of these drugs are associated with serious risks.

Most recently, a population-based study of more than 2.6 million people found that taking corticosteroids for 14 days or less was associated with a substantially greater risk for gastrointestinal (GI) bleeding, sepsis, and heart failure, particularly within the first 30 days after therapy.

In the study, Tsung-Chieh Yao, MD, PhD, a professor in the division of allergy, asthma, and rheumatology in the department of pediatrics at Chang Gung Memorial Hospital in Taoyuan, Taiwan, and colleagues used a self-controlled case series to analyze data from Taiwan’s National Health Insurance Research Database of medical claims. They compared patients’ conditions in the period from 5 to 90 days before treatment to conditions from the periods from 5 to 30 days and from 31 to 90 days after therapy.

With a median duration of 3 days of treatment, the incidence rate ratios (IRRs) were 1.80 (95% confidence interval, 1.75-1.84) for GI bleeding, 1.99 (95% CI, 1.70-2.32) for sepsis, and 2.37 (95% CI, 2.13-2.63) for heart failure.

Given the findings, physicians should weigh the benefits against the risks of rare but potentially serious consequences of these anti-inflammatory drugs, according to the authors.

“After initiating patients on oral steroid bursts, physicians should be on the lookout for these severe adverse events, particularly within the first month after initiation of steroid therapy,” Dr. Yao said in an interview.

The findings were published online July 6 in Annals of Internal Medicine.

Of the 15,859,129 adult Asians in the Taiwanese database, the study included 2,623,327 adults aged 20-64 years who received single steroid bursts (14 days or less) between Jan. 1, 2013, and Dec. 31, 2015.

Almost 60% of the indications were for skin disorders, such as eczema and urticaria, and for respiratory tract infections, such as sinusitis and acute pharyngitis. Among specialties, dermatology, otolaryngology, family practice, internal medicine, and pediatrics accounted for 88% of prescriptions.

“Our findings are important for physicians and guideline developers because short-term use of oral corticosteroids is common and the real-world safety of this approach remains unclear,” the authors wrote. They acknowledged that the database did not provide information on such potential confounders as disease severity and lifestyle factors, nor did it include children and vulnerable individuals, which may limit the generalizability of the results.

The findings echo those of a 2017 cohort study conducted by researchers at the University of Michigan in Ann Arbor. That study, by Akbar K. Waljee, MD, assistant professor of gastroenterology, University of Michigan, Ann Arbor, and colleagues, included data on more than 1.5 million privately insured U.S. adults. The researchers included somewhat longer steroid bursts of up to 30 days’ duration and found that use of the drugs was associated with a greater than fivefold increased risk for sepsis, a more than threefold increased risk for venous thromboembolism, and a nearly twofold increased risk for fracture within 30 days of starting treatment.

Furthermore, the elevated risk persisted at prednisone-equivalent doses of less than 20 mg/d (IRR, 4.02 for sepsis, 3.61 for venous thromboembolism, and 1.83 for fracture; all P < .001).

The U.S. study also found that during the 3-year period from 2012 to 2014, more than 20% of patients were prescribed short-term oral corticosteroids.

“Both studies indicate that these short-term regimens are more common in the real world than was previously thought and are not risk free,” Dr. Yao said.

Recognition that corticosteroids are associated with adverse events has been building for decades, according to the authors of an editorial that accompanies the new study.

Phase 3 trial findings compared outcomes for COPD patients who had triple fixed-dose inhaled corticosteroid, long-acting muscarinic antagonist, and long-acting beta₂ agonist with patients who received one of two dual-therapy combinations. The results were presented at the American Thoracic Society’s virtual clinical trial session.

A total of 8,509 patients were randomized on a 1:1:1:1 basis to receive twice daily:

• Single-inhaler combinations of the inhaled corticosteroid (ICS) budesonide at one of two doses, the long-acting muscarinic antagonist (LAMA) glycopyrrolate, and the long-acting beta2 agonist (LABA) formoterol.
• Dual-therapy combination glycopyrrolate and formoterol.
• Dual-therapy combination budesonide and formoterol.

The annual rate of moderate or severe COPD exacerbations was 1.08 and 1.07 for the triple combinations with 320 mcg and 180 mcg doses of budesonide, respectively, compared with 1.42 for glycopyrrolate-formoterol, and 1.24 for budesonide-formoterol.

Both triple combinations were significantly superior to the dual therapies for controlling exacerbations, reported Klaus F. Rabe, MD, PhD, from LungenClinic Grosshansdorf and Christian-Albrechts University Kiel (Germany), and colleagues in the ETHOS (Efficacy and Safety of Triple Therapy in Obstructive Lung Disease) trial (NCT02465567).

“Our findings show the benefits of triple therapy with a budesonide-glycopyrrolate-formoterol combination over dual therapy with a LAMA-LABA or an inhaled glucocorticoid-LABA combination with respect to the annual rate of moderate or severe COPD exacerbations, symptoms, and health-related quality of life in patients with moderate to very-severe COPD who are at risk of exacerbations,” they wrote in a study published online in the New England Journal of Medicine..

The trial showed for the first time that “triple therapy that has half the dose of steroid compared to a standard ICS/LABA combination has had greater efficacy for the exacerbation endpoint,” Dr. Rabe said during his presentation.

Triple-therapy combinations with an ICS, LAMA, and LABA are recommended for patients with COPD who remain symptomatic or experience further exacerbations on dual–ICS/LABA or –LAMA/LABA combinations. The triple combinations have been shown in several studies to lower risk of exacerbations and are associated with both better lung function and health-related quality of life, compared with dual therapies, the investigators noted.

However, concerns about adverse events associated with long-term ICS use – including pneumonia, cataracts, and increased fracture risk, possibly related to treatment duration, dose level, or type of corticosteroid used – spurred the ETHOS investigators to compare triple and dual fixed-dose combinations for efficacy and safety over 1 year.
 

Large study

They enrolled 8,509 adults aged 40-80 years with symptomatic COPD (defined as score of 10 or higher on the 40-point COPD Assessment Test). All patients were receiving at least two inhaled maintenance therapies at the time of screening, and had a postbronchodilator ratio of forced expiratory volume in 1 second (FEV₁) to forced vital capacity of less than 0.7, with a postbronchodilator FEV₁ of 25%-65% of the predicted normal value. The patients all had a smoking history of at least 10 pack-years and a documented history of at least one moderate or severe COPD exacerbation in the year before screening.

The patients were randomized in equal proportions to receive triple therapy with budesonide at 320- or 160-mcg doses plus glycopyrrolate 18 mcg, and formoterol 9.6 mcg twice daily, or to dual therapy with either glycopyrrolate plus formoterol at the same doses, or 320 mcg budesonide plus 9.6 mcg formoterol.

As noted, for the primary endpoint of the estimated annual rate of moderate or severe exacerbations, the triple combinations were associated with significantly lower rates, with a 24% lower rate (rate ratio, 0.76) with 320 mcg budesonide triple therapy, compared with glycopyrrolate-formoterol, and a 13% lower rate (RR, 0.87), compared with budesonide formoterol (P < .001 and P = .003, respectively).

The triple combination with the 160-mcg budesonide dose was associated with a 25% lower annual rate of exacerbations (RR, 0.75) vs. glycopyrrolate-formoterol, and a 14% lower rate (RR, 0.86) vs. budesonide-formoterol (P < .001 and P = .002, respectively).

Secondary efficacy endpoints also favored the triple combination, including a 20% lower rate ratio of severe exacerbations over 52 weeks for the 320-mcg budesonide group, compared with the budesonide-formoterol group (P = .02).

The 320-mcg dose combination was also associated with a 46% lower risk for all-cause mortality, compared with glycopyrrolate-formoterol (hazard ratio, 0.54; P = .0111).

Confirmed pneumonia was seen in 4.2% of patients on the 320-mcg budesonide dose, 3.5% of those in the 160-mcg group, and 4.5% of patients treated with budesonide-formoterol. The incidence of any adverse effect was similar across the treatment groups, ranging from 61.7% to 64.5%.
 

Balance exacerbation, pneumonia risk

In the question-and-answer session following his online presentation, Dr. Rabe was asked how the investigators reconciled their data showing increased incidence of pneumonia in budenoside-containing formulations with claims by the maker of the budesonide-formoterol (Symbicort, AstraZeneca) that budesonide is not associated with increased risk of pneumonia.

“We have to say that there are individuals that we have to balance the benefit of [less] exacerbation against the risk of pneumonia,” he replied, but noted that the size of the effect, observed both in ETHOS and in the KRONOS trial, was relatively small.

“This definitely adds some information for us to think about when we’re trying to do risk-benefit analysis,” commented MeiLan K. Han, MD, MS, from the University of Michigan, who moderated the session but was not involved in the study.

The ETHOS trial was funded by AstraZeneca. Dr. Rabe disclosed consulting/advisory board activity with that company and others. Dr. Han has previously disclosed consulting/advising and research funding relationships with other companies.

Phase 3 trial findings compared outcomes for COPD patients who had triple fixed-dose inhaled corticosteroid, long-acting muscarinic antagonist, and long-acting beta₂ agonist with patients who received one of two dual-therapy combinations. The results were presented at the American Thoracic Society’s virtual clinical trial session.

A total of 8,509 patients were randomized on a 1:1:1:1 basis to receive twice daily:

• Single-inhaler combinations of the inhaled corticosteroid (ICS) budesonide at one of two doses, the long-acting muscarinic antagonist (LAMA) glycopyrrolate, and the long-acting beta2 agonist (LABA) formoterol.
• Dual-therapy combination glycopyrrolate and formoterol.
• Dual-therapy combination budesonide and formoterol.

The annual rate of moderate or severe COPD exacerbations was 1.08 and 1.07 for the triple combinations with 320 mcg and 180 mcg doses of budesonide, respectively, compared with 1.42 for glycopyrrolate-formoterol, and 1.24 for budesonide-formoterol.

Both triple combinations were significantly superior to the dual therapies for controlling exacerbations, reported Klaus F. Rabe, MD, PhD, from LungenClinic Grosshansdorf and Christian-Albrechts University Kiel (Germany), and colleagues in the ETHOS (Efficacy and Safety of Triple Therapy in Obstructive Lung Disease) trial (NCT02465567).

“Our findings show the benefits of triple therapy with a budesonide-glycopyrrolate-formoterol combination over dual therapy with a LAMA-LABA or an inhaled glucocorticoid-LABA combination with respect to the annual rate of moderate or severe COPD exacerbations, symptoms, and health-related quality of life in patients with moderate to very-severe COPD who are at risk of exacerbations,” they wrote in a study published online in the New England Journal of Medicine..

The trial showed for the first time that “triple therapy that has half the dose of steroid compared to a standard ICS/LABA combination has had greater efficacy for the exacerbation endpoint,” Dr. Rabe said during his presentation.

Triple-therapy combinations with an ICS, LAMA, and LABA are recommended for patients with COPD who remain symptomatic or experience further exacerbations on dual–ICS/LABA or –LAMA/LABA combinations. The triple combinations have been shown in several studies to lower risk of exacerbations and are associated with both better lung function and health-related quality of life, compared with dual therapies, the investigators noted.

However, concerns about adverse events associated with long-term ICS use – including pneumonia, cataracts, and increased fracture risk, possibly related to treatment duration, dose level, or type of corticosteroid used – spurred the ETHOS investigators to compare triple and dual fixed-dose combinations for efficacy and safety over 1 year.
 

Large study

They enrolled 8,509 adults aged 40-80 years with symptomatic COPD (defined as score of 10 or higher on the 40-point COPD Assessment Test). All patients were receiving at least two inhaled maintenance therapies at the time of screening, and had a postbronchodilator ratio of forced expiratory volume in 1 second (FEV₁) to forced vital capacity of less than 0.7, with a postbronchodilator FEV₁ of 25%-65% of the predicted normal value. The patients all had a smoking history of at least 10 pack-years and a documented history of at least one moderate or severe COPD exacerbation in the year before screening.

The patients were randomized in equal proportions to receive triple therapy with budesonide at 320- or 160-mcg doses plus glycopyrrolate 18 mcg, and formoterol 9.6 mcg twice daily, or to dual therapy with either glycopyrrolate plus formoterol at the same doses, or 320 mcg budesonide plus 9.6 mcg formoterol.

As noted, for the primary endpoint of the estimated annual rate of moderate or severe exacerbations, the triple combinations were associated with significantly lower rates, with a 24% lower rate (rate ratio, 0.76) with 320 mcg budesonide triple therapy, compared with glycopyrrolate-formoterol, and a 13% lower rate (RR, 0.87), compared with budesonide formoterol (P < .001 and P = .003, respectively).

The triple combination with the 160-mcg budesonide dose was associated with a 25% lower annual rate of exacerbations (RR, 0.75) vs. glycopyrrolate-formoterol, and a 14% lower rate (RR, 0.86) vs. budesonide-formoterol (P < .001 and P = .002, respectively).

Secondary efficacy endpoints also favored the triple combination, including a 20% lower rate ratio of severe exacerbations over 52 weeks for the 320-mcg budesonide group, compared with the budesonide-formoterol group (P = .02).

The 320-mcg dose combination was also associated with a 46% lower risk for all-cause mortality, compared with glycopyrrolate-formoterol (hazard ratio, 0.54; P = .0111).

Confirmed pneumonia was seen in 4.2% of patients on the 320-mcg budesonide dose, 3.5% of those in the 160-mcg group, and 4.5% of patients treated with budesonide-formoterol. The incidence of any adverse effect was similar across the treatment groups, ranging from 61.7% to 64.5%.
 

Balance exacerbation, pneumonia risk

In the question-and-answer session following his online presentation, Dr. Rabe was asked how the investigators reconciled their data showing increased incidence of pneumonia in budenoside-containing formulations with claims by the maker of the budesonide-formoterol (Symbicort, AstraZeneca) that budesonide is not associated with increased risk of pneumonia.

“We have to say that there are individuals that we have to balance the benefit of [less] exacerbation against the risk of pneumonia,” he replied, but noted that the size of the effect, observed both in ETHOS and in the KRONOS trial, was relatively small.

“This definitely adds some information for us to think about when we’re trying to do risk-benefit analysis,” commented MeiLan K. Han, MD, MS, from the University of Michigan, who moderated the session but was not involved in the study.

The ETHOS trial was funded by AstraZeneca. Dr. Rabe disclosed consulting/advisory board activity with that company and others. Dr. Han has previously disclosed consulting/advising and research funding relationships with other companies.

Potentially preventable inpatient admissions accounted for almost 9% of all adult hospital costs in 2017, according to the Agency for Healthcare Research and Quality.

That year, there were 27.4 million inpatient visits by adults with a total cost of $380.1 billion, although obstetric stays were not included in the analysis. Of those inpatient admissions, 3.5 million (12.9%) were deemed to be “avoidable, in part, through timely and quality primary and preventive care,” Kimberly W. McDermott, PhD, and H. Joanna Jiang, PhD, said in a recent AHRQ statistical brief.

The charges for those 3.5 million visits came to $33.7 billion, or 8.9% of aggregate hospital costs in 2017, based on data from the AHRQ Healthcare Cost and Utilization Project’s state inpatient databases.

“Determining the volume and costs of potentially preventable inpatient stays can identify where potential cost savings might be found associated with reducing these hospitalizations overall and among specific subpopulations,” the investigators pointed out.

Of the seven conditions that are potentially avoidable, heart failure was the most expensive, producing more than 1.1 million inpatient admissions at a cost of $11.2 billion. Diabetes was next with a cost of almost $7.4 billion, followed by chronic obstructive pulmonary disease (COPD) at nearly $7.3 billion, they said.

Those three conditions, along with hypertension and asthma in younger adults, brought the total cost of the preventable-stay equation’s chronic side to $27.3 billion in 2017, versus $6.4 billion for the two acute conditions, community-acquired pneumonia and urinary tract infections, said Dr. McDermott of IBM Watson Health and Dr. Jiang of the AHRQ.

The rate of potentially avoidable stays for chronic conditions was higher for men (1,112/100,000 population) than for women (954/100,000), but women had a higher rate for acute conditions, 346 vs. 257, which made the overall rates similar (1,369 for men and 1,300 for women), they reported.

Differences by race/ethnicity were more striking. The rate of potentially avoidable stays for blacks was 2,573/100,000 in 2017, compared with 1,315 for Hispanics, 1,173 for whites, and 581 for Asians/Pacific Islanders. The considerable margins between those figures, however, were far eclipsed by the “other” category, which had 4,911 stays per 100,000, the researchers said.

Large disparities also can be seen when looking at community-level income. Communities with income in the lowest quartile had a preventable-hospitalization rate of 2,013/100,000, and the rate dropped with each successive quartile until it reached 878/100,000 for the highest-income communities, according to the report.

“High hospital admission rates for these conditions may indicate areas where changes to the healthcare delivery system could be implemented to improve patient outcomes and lower costs,” Dr. McDermott and Dr. Jiang wrote.

There is concern that the COVID-19 pandemic may be inflicting collateral damage on vulnerable patients with chronic conditions, in particular, those with COPD, according to a commentary published in CHEST (2020 May 28. doi: 10.1016/j.chest.2020.05.549) by a group of physicians who study COPD.

Not only is COPD among the most prevalent underlying diseases among hospitalized COVID-19 patients (Clin Microbiol Infect. 2020 Jun 8. doi: 10.1016/j.cmi.2020.05.041), but other unanticipated factors of treatment put these patients at extra risk. Valerie Press, MD, assistant professor of medicine and pediatrics at the University of Chicago, and colleagues aimed to alert physicians to be aware of potential negative effects, or collateral damage, that the pandemic can have on their patients with COPD, even those without a COVID-19 diagnosis.

These concerns include that patients may delay presenting to the ED with acute exacerbations of COPD and once they present they may be at later stages of the exacerbation. Further, evaluation for COVID-19 as a possible trigger of acute exacerbations of COPD (AECOPD) is essential; however, implementing proven AECOPD therapies remains challenging. For instance, routine therapy with corticosteroids for AECOPD may be delayed due to diagnostic uncertainty and hesitation to treat COVID-19 with steroids while COVID-19 testing is pending,” Dr. Press and her colleagues stated.

Shortages and scarcity of medications such as albuterol inhalers to treat COPD have been reported. In addition, patients with COPD are currently less likely to access their health care providers because of fear of COVID-19 infection. This barrier to care and the current higher threshold for presenting to the hospital may to lead to more cases of AECOPD and worsening health in these patients, according to the authors.

Dr. Press said in an interview: “Access to medications delivered through inhalers is challenging even without the pandemic due to high cost of medications. Generic medications are key to improving access for patients with chronic lung disease, so once the generic albuterol becomes available, this should help with access. In the meantime, some companies help provide medications at reduced cost, but usually only on a short time basis. In addition, some pharmacies have lower-cost albuterol inhalers, but these are often not supplied with a full month of dosing.”

In addition to all these concerns is the economic toll this pandemic is taking on patients. The association between COPD and socioeconomic status has been studied in depth (Am J Respir Crit Care Med. 2019; 199[8]:961-69) and would indicate that low-income patients with COPD would face an increased burden during an economic downturn. The authors noted, “Historic rapid job loss and unemployment in the U.S., coupled with a health system of employment-integrated health insurance coverage, makes it more likely that people with COPD will not be able to afford their medication.”

Dr. Press stressed that the COVID pandemic has highlighted critically important disparities in access to health care and disparities in health. “Many of the recommendations regarding stay-at-home and other safety mechanisms to prevent contracting and spreading COVID-19 have not been feasible for all sub-populations in the United States. Those that were essential workers did not have the ability to stay home. Further, those that rely on public transportation had less opportunities to social distance. Finally, while telemedicine opportunities have advanced for clinical care, not all patients have equal access to these capabilities and health disparities could widen in this regard as well. Clinicians have a responsibility to identify social determinants of health that increase risks to our patients’ health and limit their safety.”*

The authors offer some concrete suggestions of how physicians can address some of these concerns, including the following:

• Be alert to potential barriers to accessing medication and be aware of generic albuterol inhaler recently approved by the FDA in response to COVID-19–related shortages.
• Use telemedicine to monitor patients and improvement of home self-management. Clinicians should help patients “seek care with worsening symptoms and have clear management guidelines regarding seeking phone/video visits; implementing therapy with corticosteroids, antibiotics, or inhalers and nebulizers; COVID-19 testing recommendations; and thresholds for seeking emergent, urgent, or outpatient care in person,” Dr. Press added, “Building on the work of nurse advice lines and case management and other support services for high-risk patients with COPD may continue via telehealth and telephone visits.”
• Ensure that untried therapy for COVID-19 “does not displace proven and necessary treatments for patients with COPD, hence placing them at increased risk for poor outcomes.”

Dr. Press is also concerned about the post–COVID-19 period for patients with COPD. “It is too early to know if there are specific after effects of the COVID infection on patients with COPD, but given the damage the virus does to even healthy lungs, there is reason to have concern that COVID could cause worsening damage to the lungs of individuals with COPD.”

She noted, “Post-ICU [PICU] syndrome has been recognized in patients with ARDS generally, and patients who recover from critical illness may have long-lasting (and permanent) effects on strength, cognition, disability, and pulmonary function. Whether the PICU syndrome in patients with ARDS due to COVID-19 specifically is different from the PICU syndrome due to other causes remains unknown. But clinicians whose patients with COPD survive COVID-19 may expect long-lasting effects and slow recovery in cases where COVID-19 led to severe ARDS and a prolonged ICU stay. Assessment of overall patient recovery and functional capacity (beyond lung function and dyspnea symptoms) including deconditioning, anxiety, PTSD, weakness, and malnutrition will need to be addressed. Additionally, clinicians may help patients and their families understand the expected recovery and help facilitate family conversations about residual effects of COVID-19.”

Death rates for combined asthma and chronic obstructive pulmonary disease declined during 1999-2016, but the risk remains higher among women, compared with men, and in certain occupations, according to a recent report from the Centers for Disease Control and Prevention.

There is also an association between mortality and nonworking status among adults aged 25-64 years, which “suggests that asthma-COPD overlap might be associated with substantial morbidity,” Katelynn E. Dodd, MPH, and associates at the CDC’s National Institute for Occupational Safety and Health said in the Morbidity and Mortality Weekly Report. “These patients have been reported to have worse health outcomes than do those with asthma or COPD alone.”

For females with asthma-COPD overlap, the age-adjusted death rate among adults aged 25 years and older dropped from 7.71 per million in 1999 to 4.01 in 2016, with corresponding rates of 6.70 and 3.01 per million for males, they reported.

In 1999-2016, a total of 18,766 U.S. decedents aged ≥25 years had both asthma and COPD assigned as the underlying or contributing cause of death (12,028 women and 6,738 men), for an overall death rate of 5.03 per million persons (women, 5.59; men, 4.30), data from the National Vital Statistics System show.

Additional analysis, based on the calculation of proportionate mortality ratios (PMRs), also showed that mortality varied by occupational status and age for both males and females, the investigators said, noting that workplace exposures, such as dusts and secondhand smoke, are known to cause both asthma and COPD.

The PMR represents the observed number of deaths from asthma-COPD overlap in a specified industry or occupation, divided by the expected number of deaths, so a value over 1.0 indicates that there were more deaths associated with the condition than expected, Ms. Dodd and her associates explained.

Among female decedents, the occupation with the highest PMR that was statistically significant was bartending at 3.28. For men, the highest significant PMR, 5.64, occurred in logging workers. Those rates, however, only applied to one of the two age groups: 25-64 years in women and ≥65 in men, based on data from the National Occupational Mortality Surveillance, which included information from 26 states for the years 1999, 2003, 2004, and 2007-2014.

Occupationally speaking, the one area of common ground between males and females was lack of occupation. PMRs for those aged 25-64 years “were significantly elevated among men (1.98) and women (1.79) who were unemployed, never worked, or were disabled workers,” they said. PMRs were elevated for nonworking older males and females but were not significant.

The elevated PMRs suggest “that asthma-COPD overlap might be associated with substantial morbidity resulting in loss of employment [because] retired and unemployed persons might have left the workforce because of severe asthma or COPD,” the investigators wrote.
