Insurance delays in the approval of biologic medications for patients with psoriasis and psoriatic arthritis.

Biologics are the most effective treatment for moderate-to-severe psoriasis. Insurance approval and need for prior authorization continue to be a barrier to care for many patients with psoriasis and psoriatic arthritis. We sought to determine whether race/ethnicity, insurance type, and provider specialty affect biologic approval times. Records from the University of Miami Health System were reviewed, and 101 patients were included. Need for a prior authorization was significantly associated with long waits (p = 2.4 × 10-5). We did not identify a significant difference in wait times between non-Hispanic Whites and non-Whites. The average wait time for biologic approval for Whites was 29.7 days and for non-Whites was 27.2 days. Biologics were approved the same day for 23.7% of HMO carriers, 11.5% of PPO carriers, 63% of Medicare carriers, and 40% of Medicaid carriers (p < 0.001). There was no difference in the biologic type prescribed based on insurance type. Medicaid (p < 0.05) and the need for prior authorization (p = 2.4 × 10-5) significantly predicted approval wait time in our multilinear regression model. Patients with Medicare had the shortest wait time with a mean of 7.3 days. Medicaid patients waited a mean of 11.3 days. Private insurance patients waited the longest, regardless of whether they had a PPO (37 days) or HMO (41.3 days).
