Racial differences in primary care opioid risk reduction strategies

Abstract

PURPOSE Racial disparities in treating pain with opioids are widely reported; however, differences in use of recommended strategies to reduce the risk of opioid misuse by race/ethnicity have not been evaluated. METHODS In a retrospective cohort of black and white patients with chronic noncancer pain prescribed opioid analgesics for at least 3 months, we assessed physicians' use of 3 opioid risk reduction strategies: (1) urine drug testing, (2) regular office visits (at least 1 visit per 6 months on opioids and within 30 days of an opioid change), and (3) restricted early opioid refills (receipt of a refill >1 week early less than twice). Nonlinear mixed effect regression models accounted for clustering within physician and adjusted additively for demographics, substance abuse, mental health and medical comorbidities, health care factors, and practice site. RESULTS Of the 1,612 patients studied, 62.1% were black. Black patients were more likely than white patients to receive urine drug testing (10.4% vs 4.1%), regular office visits (56.4% vs 39.0%), and restricted early refills (79.4% vs 72.0%) (P
