The identification of predictors of chronic use in this population may provide clinical guidance for treatment selection.\nMETHODS:\nWomen with an initial claim for endometriosis (N=39,513) aged 18-50 years were identified from a US commercial insurance claims database and followed for 2 years. Chronic opioid use was defined as ≥10 fills or ≥120 days covered in 365 days. Multivariable logistic regression models were used to identify potential predictors of chronic opioid use.\nRESULTS:\nOver 2 years, 4.4% of women with endometriosis became chronic opioid users. Risk factors for chronic use included fibromyalgia (OR 1.54; 95% CI 1.12-2.10), back pain (OR 1.42; 95% CI 1.15-1.75), migraines (OR 1.39; 95% CI 1.07-1.81), tobacco use (OR 1.56; 95% CI 1.22-2.00), antidepressants (OR 1.69; 95% CI 1.39-2.05), antipsychotics (OR 2.03; 95% CI 1.41-2.91), benzodiazepine (OR 1.57; 95% CI 1.27-1.94) and prior use of opioids (OR 4.83; 95% CI 4.02-5.81). These characteristics were more frequent in women with than without endometriosis: fibromyalgia (4% vs 2%), back pain (14% vs 8%), migraines (6% vs 2%), tobacco use (4% vs 2%), antidepressants (19% vs 13%), antipsychotics (2% vs 1%), benzodiazepine (11% vs 5%) and prior use of opioids (34% vs 13%) (p<0.01).\nCONCLUSION:\nWomen with endometriosis who are exposed to opioids and are at high-risk for chronic opioid use may be identified based on comorbidities and concomitant medication use. Opioid prescribing should be carefully considered among high-risk women.","source_license":"CC0","license_restricted":false}
