OBJECTIVES:
According to the CDC, as of December 2022, almost one in three Americans had confirmed COVID-19 infection; yet only a small portion generated healthcare claims related to COVID-19. Higher burden of COVID-19 cases in Northeastern states compared to other US regions has been documented. This study examined the regional variation in demographic characteristics and treatment patterns among patients with a claim for COVID-19 in a nationwide US claims database.METHODS:
Analysis of data from over 277 million patients in IQVIA’s longitudinal medical and pharmacy claims databases resulted in a cohort of 17,682,111 patients with COVID-19 diagnosis between 4/1/2020 and 4/30/2022. Demographic characteristics and treatment rates for key approved and un-approved COVID-19 therapies were assessed and stratified by region.RESULTS:
Among patients in the database, 6.4% had a COVID-19 diagnosis. The proportion was higher in the Northeast (7.1%) and South (6.9%) compared with the West (4.8%). The highest proportion of patients were aged 18-44 years (32.7% in South to 35.2% in West). Over a fifth of the patients were ≥ 65 years old (US overall= 23.7%; 22.5% in Northeast to 25.8% in Midwest). Approximately 57% of the patients nationally and within each region were women. For approved medications, utilization ranged from 1.7% in Northeast to 2.7% in Midwest (overall:2.2%) for remdesivir; 0.7% in Northeast to 2.2% in South (overall: 1.5%) for casirivimab/imdevimab. For unapproved medications, utilization ranged from 0.9% in Northeast to 1.6% in South (overall:1.3%) for hydroxychloroquine and 0.4% in Northeast to 1.8% in South (overall:1.1%) for ivermectin.CONCLUSIONS:
Less than one in five US cases of COVID-19 had a claim with diagnosis of COVID-19. Use of COVID-19 specific medications remained low throughout the pandemic. Despite the higher disease burden, proportion of patients with claims and receiving COVID-19 treatment were low nationally, particularly in the northeast US region.Conference/Value in Health Info
