ABSTRACT
BACKGROUND: Early after the onset of the COVID-19 pandemic, concerns were raised that the use of psoriasis treatments, particularly biologic therapies because of their immunosuppressant effects, could be associated with a poor prognosis in the case of COVID-19 infection. OBJECTIVE: To examine changes in adherence to systematic biologic therapies for psoriasis after the onset of the COVID-19 pandemic. METHODS: Using IQVIA medical and pharmacy claims data from January 1, 2018, to October 31, 2020, we identified patients aged 18 years or older who had a diagnosis of plaque psoriasis in 2018 and who received systemic biologic therapies for psoriasis, including both provider-administered and pharmacy-dispensed therapies. We calculated the incidence of 14-day gaps without therapy per 1,000 study participants for each 30-day interval. We constructed interrupted time series analyses to test changes in the incidence of outcomes after the pandemic declaration. RESULTS: The sample included 15,890 study participants: 45.4% were female and 15.2% were aged 65 years or older. For patients using biologic therapies dispensed from the pharmacy, there was a 13.1% decrease in the incidence of 14-day gaps without biologic therapy immediately after pandemic declaration, from 92.4 gaps per 1,000 patients to 80.2 gaps per 1,000 patients, but this decrease was not statistically significant. However, for patients using provider-administered therapies, the incidence of 14-day gaps without biologic therapy increased by 55.1% after pandemic declaration, from 29.0 gaps per 1,000 patients to 44.9 gaps per 1,000 patients (P < 0.01). CONCLUSIONS: Following the onset of the COVID-19 pandemic, we found an increased incidence of gaps in biologic therapy for psoriasis among users of provider-administered treatments but not among users of pharmacy-dispensed therapies.
