Women with endometriosis were significantly more likely than controls to fill opioid prescriptions, including higher doses, and to concurrently use opioids and benzodiazepines.

Abstract

OBJECTIVE: To examine opioid use, opioid prescribing patterns, and timing of the first opioid prescription in endometriosis patients compared with matched women in the control group without endometriosis. METHODS: We conducted a retrospective analysis of the Clinformatics Datamart database. Women diagnosed with endometriosis from January 2006 through December 2016 and aged 18-49 years were compared with women in the control group matched on age, region, race, insurance payer, and plan type. Key outcomes included: filled prescription for an opioid, multiple opioid prescriptions, number of days' supply, daily dose (morphine milligram equivalents), and concomitant opioid and benzodiazepine prescriptions. Cohorts were descriptively analyzed using t- and χ statistics and multivariable regression analyses yielded adjusted relative risk (RR) ratios and 95% CI. RESULTS: The study sample included 53,847 endometriosis patients and 107,694 patients in the control group. The mean age was 38 years, 62.4% of patients were white, and 51.6% lived in the South. Women in the endometriosis case group, compared with women in the control group, were more likely to fill an opioid prescription (42,705 [79.3%] women in the case group vs 26,106 [24.2%] women in the control group; adjusted RR ratio 2.91; 2.87-2.94), had higher likelihood of filling prescriptions with a dose of 50 morphine milligram equivalents or more (24,544 [45.6%] vs 10,463 [9.7%]; adjusted RR ratio 4.07; 3.98-4.16) or 100 morphine milligram equivalents or more (8,013 [14.9%] vs 3,582 [3.3%]; adjusted RR ratio 3.56; 3.43-3.70). Women in the case group were more likely to have concomitant opioid and benzodiazepine prescriptions (5,453 [10.1%] vs 3,711 [3.5%]; adjusted RR ratio 1.95; 1.88-2.03) and to have used these drugs concurrently for at least 30 days (1,596 [3.0%] vs 1,265 [1.2%]; adjusted RR ratio 1.43; 1.34-1.52) or at least 90 days (875 [1.6%] vs 777 [0.7%]; adjusted RR ratio 1.27; 1.17-1.37). Similar results were obtained after excluding opioid prescriptions received during a 30-day postsurgery window. CONCLUSION: Women with endometriosis had higher probabilities of prolonged use of opioids and concomitant use with benzodiazepines compared with women without this condition.
