Most JF, Ambrose CS, Chung Y, et al. - This investigation was carried out among U.S. patients with severe asthma, to quantify the frequency of asthma specialist visits as well as to recognize patient demographic and clinical features related to specialist visits. In addition, health outcomes post-specialist care were also reported. Using the IQVIA PharMetrics Plus database of commercially insured individuals, severe asthma patients aged 6 years or older were selected. There were 54,332 patients, of which 38.2% were found to have 1 or more specialist visits over 2 years. Asthma exacerbation frequency, younger age, and allergy/respiratory comorbidity burden, were revealed as patient features that can predict specialist visits. Lower prevalence of asthma exacerbations and rescue inhaler use, post-first observed specialist visit, was detected in patients with 1 or more specialist visits. Findings revealed that fewer than half of U.S. patients with severe asthma received specialist care, and least frequent specialist care was noted in older adult patients and in those with more nonrespiratory comorbidities. Improved care and patient outcomes may be achieved through increased specialist involvement in managing severe asthma.
