A Medscape/CHEST Survey
There are differences in how pulmonologists and other clinicians approach the diagnosis and management of patients with moderate to severe asthma, according to a survey conducted by Medscape in collaboration with CHEST, the American College of Chest Physicians. Despite some of these differences, those surveyed do predominantly favor similar treatment options, including inhaled corticosteroids and biologics. Biologics in particular are perceived as a promising therapeutic approach for moderate to severe asthma by clinicians overall, and many are also comfortable prescribing them.
Medscape and CHEST asked 763 clinicians about their views on moderate to severe asthma. Responses came from 100 pulmonologists; 102 allergists/immunologists; 102 critical care medicine physicians; 100 emergency medicine (EM) physicians; 104 pediatricians; 100 primary care physicians (PCPs); and 155 nurse practitioners (NPs), physician assistants (PAs), or registered nurses (RNs).
Inhaled Steroids Top Treatment Choice
Survey respondents ranked an inhaled corticosteroid with a long-acting bronchodilator as the favored medication for patients with moderate to severe asthma; 83% of allergists/immunologists feel this way, as do between 52% and 63% of the other clinicians, including pulmonologists.
Inhaled corticosteroids alone are generally preferred by 23%-28% of clinicians surveyed, with the exception of allergists/immunologists (12%). EM physicians (19%) and pediatricians (16%) tend to more often favor an inhaled corticosteroid and leukotriene-modifying agent than do other clinicians, but notably, none of the allergists/immunologists felt this way.
Biologics Are an Important Step Forward
When it comes to biologic agents for moderate to severe asthma, it is allergists/immunologists (91%) who say they are most comfortable prescribing them. This percentage drops to 59% for pulmonologists, 34% for NP/PA/RNs, 20% for critical care medicine physicians, 16% for PCPs, 7% for pediatricians, and just 2% of EM physicians
Aaron B. Holley, MD, FCCP, program director at the Pulmonary and Critical Care Medical Fellowship, Department of Medicine, Walter Reed National Military Medical Center, Bethesda, Maryland, and a member of the Moderate to Severe Asthma Center of Excellence steering committee, noted that the latest rage is to personalize treatment by “phenotyping” asthma, with the thought being that certain asthma phenotypes will respond well to some treatments, but not to others. “This sounds good in academic and scientific papers, but remains difficult to operationalize in the clinic,” said Holley.
He also noted that the new biologics all target one specific phenotype: eosinophilic asthma. “This phenotype makes up approximately 50% of all patients with asthma; however, the other 50% have no targeted treatments available, and they don’t necessarily respond well to conventional inhaler therapy,” said Holley.
And for patients with severe, poorly responsive asthma, it’s hard to say precisely what percentage is being treated inappropriately for their phenotype, versus what percentage is noncompliant, versus what percentage is due to socioeconomic status and behavioral health issues, he noted.
The solution? “There is no easy solution,” said Holley. “More specialized, severe asthma clinics? Greater education on inhaler use and disease severity? Concomitant management of behavioral health complaints? All these are necessary, but they’re also resource-intensive.”
Still, in his view, the glass is half-full. “The biologics are an important step forward, and we’re getting better at phenotyping. Compared with 5-10 years ago, we’re in a much better place.”
Preferred Biomarkers
Familiarity with biomarkers for moderate or severe asthma is universal among pulmonologists. Only 2% of allergists/immunologists are not familiar with biomarkers, compared with nearly three quarters of EM physicians, 45% of pediatricians, 36% of PCPs, 31% of NP/PA/RNs, and 20% of critical care medicine physicians.
Immunoglobulin E (IgE) levels ranked as the most important biomarker for moderate or severe asthma, favored by 47% of pulmonologists and 50% of allergists/immunologists, followed by eosinophils, preferred by 44% of pulmonologists and 38% of allergists/immunologists. Between 26% and 36% of other clinicians rank IgE tops, except for EM physicians (13%). About one third of critical care medicine physicians and one quarter of PCPs and NP/PA/RNs think eosinophils are the most important biomarker, compared with only 14% of pediatricians and 10% of EM physicians.
Fraction of exhaled nitric oxide (FeNO) is least favored by all clinicians surveyed. Just 9% of pulmonologists, 12% of allergists/immunologists, and 5% of EM physicians like this biomarker. Pediatricians ranked FeNO the highest among those surveyed, but only at 14%.
Assessment Tools and Guidelines
One “interesting” finding is the difference between specialties in use of the Asthma Control Test (ACT) and Asthma Control Questionnaire (ACQ), commented Holley. Most pulmonologists (57%) and allergists/immunologists (79%) favor ACTs for adults and children, whereas other clinicians seem to favor the ACQ.
Both the ACT and ACQ have decent literature to support their use, he noted. “I use the ACT, but personally, I don’t think it makes a difference which you use. I do think it’s important to get an objective score for their subjective symptoms to facilitate tracking over time, and to ensure that clinicians are speaking the same language. For example, if someone else sees my patient for some reason, one look at the ACT score will summarize their disease control, as opposed to them having to pull it out of a running narrative history,” said Holley.
ACTs are also favored by 39% of NP/PA/RNs, 34% of pediatricians, 27% of PCPs, 16% of critical care medicine physicians, and just 6% of EM physicians. About one third of EM physicians and PCPs (34% each) favor the ACQ, as do 30% of NP/PA/RNs, 29% of pediatricians, 20% of pulmonologists, 17% of allergists/immunologists, and 8% of EM physicians.
Thirty-six percent of all clinicians said they don’t use any assessment tool to gauge asthma control in patients with moderate to severe asthma, including 86% of EM physicians and 42% of PCPs – the specialties most apt to report no use.
As for guideline use, 83% of allergists/immunologists and 81% of pediatricians surveyed use the National Asthma Education and Prevention Program (NAEPP) guidelines. Pulmonologists tend to use these guidelines less often (37%), as they also rely on the Global Initiative for Asthma (GINA) (54%) and European Respiratory Society (ERS)/American Thoracic Society (ATS) guidelines (43%).
About two thirds (62%) of NP/PA/RNs favor the NAEPP guidelines, as do 49% of PCPs and critical care medicine physicians and 31% of EM physicians. Sixty percent of EM physicians don’t use guidelines at all.
Chief Culprits Behind Poor Asthma Control
Clinicians tend to see a lack of appropriate treatment as the greatest barrier for patients with moderate to severe asthma; 63% of pulmonologists feel this way, as do 60% of allergists/immunologists, 52% of PCPs, 50% of pediatricians, and 45% of NP/PA/RNs, compared with just 32% of EM and critical care medicine physicians. EM (67%) and critical care medicine (54%) physicians are also more apt to think that the patient not seeing a provider is the greatest barrier.
Overall, most clinicians surveyed link poor asthma control to poor medication adherence and social or environmental risk irritants, such as smoking, secondhand smoke exposure, vaping, and pollutants.
“No surprise here,” said Holley. “In my experience, medication adherence and environmental risks or irritants are big factors in patients with moderate to severe asthma who don’t respond to conventional, standard asthma treatment and continue to progress.”
“We know from data that poor control is related to socioeconomic status and behavioral health. We also know that proper inhaler use and compliance are a big problem. Does this account for most ‘progression’? That’s hard to say, I suppose, but certainly these are big factors,” Holley added.
Echoing Holley, Navitha Ramesh, MD, clinical assistant professor of medicine at the Department of Clinical Sciences, Geisinger Commonwealth School of Medicine, Scranton, Pennsylvania, who is also a member of the Moderate to Severe Asthma Center of Excellence steering committee, said the biggest barriers to treatment, in her experience, are “poor health literacy, medication nonadherence, poor social support, and tobacco use.”
The survey was conducted August 29, 2018, to October 11, 2018. Pulmonologists were recruited from CHEST, and all other clinicians were recruited from Medscape members. Patients with moderate to severe asthma account for at least half of all patients with asthma seen by pulmonologists, allergists/immunologists, and critical care medicine physicians; this proportion falls to about 30% among pediatricians and PCPs. Of the clinicians surveyed, patients with moderate to severe asthma are overwhelmingly referred to pulmonologists. Among the reasons for referral are multiple emergency department visits, poor control, failure on first-line therapy, and confounding factors.
