While most commercially insured patients with asthma have good disease control, some patients may not, according to a recent review of U.S. administrative claims data.
The results of the retrospective analysis, presented at the annual meeting of the American Academy of Allergy, Asthma, and Immunology, held virtually this year, showed some patients with asthma had two or more refills for prescribed systemic corticosteroids (SCS) or short-acting beta agonists (SABA) within a period of 12 months.
“,” Randall Brown, MD, MPH, pulmonologist and senior director of Global Respiratory Medical Affairs at Teva Pharmaceuticals in West Chester, Penn., said in a presentation at the meeting. “Understanding the extent of systemic steroid and SABA prescriptions among patients with asthma and the distribution of those prescriptions across disease severity can be useful in determining the degree of disease control.”
Global Initiative for Asthma (GINA) guidelines consider factors such as symptom control and risk of exacerbation when determining asthma severity, but uncontrolled asthma can still be difficult to assess. Dr. Brown and colleagues set out to determine the prevalence of uncontrolled asthma for patients in the IBM/Watson MarketScan U.S. claims database as well as the rate of uncontrolled asthma by GINA classification. In total, 597,955 patients who had an asthma diagnosis between 12 months before or up to 3 months after the index data of filling a SABA prescription were included for analysis. Patients were at least 12 years old with commercial insurance for at least 12 months, and had no other respiratory diseases other than asthma during the 12 months prior to the index date and during the study period.
The researchers then measured each patient’s 2018 GINA classification of asthma severity based on the number of SCS and SABA prescription claims made between January and December 2017. Overall, 54.3% patients were GINA Step 1, 14.6% were Step 2, 10.2% were Step 3, 19.8% were Step 4, and 1.1% were Step 5.
Dr. Brown and colleagues found that, regardless of GINA disease severity, 18.8% of patients filled two or more SCS prescriptions in 1 year, 27.4% filled three or more SABA prescriptions in 1 year, and 38.7% filled two or more SCS and/or three or more SABA prescriptions in 1 year. “[A] large proportion of these patients did not meet the GINA goal of disease control,” Dr. Brown said.
The researchers found 13% of patients with uncontrolled asthma categorized as GINA Step 1, 20% of patients categorized as GINA Step 2, 19% of patients who were GINA Step 3, 31% of patients who were GINA Step 4, and 54% of patients categorized as GINA Step 5 filled two or more two or more SCS prescriptions per year.
The proportion of patients with uncontrolled asthma who filled three or more SABA prescriptions per year included 19% in GINA Step 1, 29% in GINA Step 2, 35% in GINA Step 3, 44% in GINA Step 4, and 57% in GINA Step 5 groups. For patients who filled both two or more SCS and/or three or more SABA prescriptions per year, the proportion of patients with uncontrolled asthma by GINA category was 29% in GINA Step 1, 42% in GINA Step 2, 46% in GINA Step 3, 58% in GINA Step 4, and 76% of patients in GINA Step 5.
While “poor control was seen across all of the GINA disease severity classifications, the greatest proportion of uncontrolled disease was seen at the highest disease severity, which was also true when we used a stricter definition of uncontrolled disease,” Dr. Brown said. When the researchers applied stricter criteria for patients categorized as GINA Step 5, 39% of patients filled three or more SCS, 41% filled four or more SABA, and 60% filled three or more SCS and/or four or more SABA prescriptions over 12 months.
Dr. Brown said that the analysis “highlights the need for improved asthma management strategies within each of the asthma GINA classification steps.”
“While this population that was studied may be reflective of the wider insured U.S. population, the proportions of uncontrolled asthma may be even greater in non–commercially insured patients within the United States,” he said. “Updates to GINA guidelines incorporate recent consensus [and] recent scientific information and therapies, but many patients in the U.S. are not meeting the GINA goal of disease control. Newer paradigms for systemic corticosteroid-free asthma control as a target of disease ‘remission’ are becoming more commonplace. Such changes and goals may lead to improved asthma management strategies and advancement in treatment.”
