Abstract

A recent multi-state analysis found Maine had the second highest average annual increase in opioid use disorder (OUD) at delivery hospitalization, with 34.1 OUD per 1,000 delivery hospitalizations in 2012. The objective of this analysis is to describe the prevalence and characteristics of OUD deliveries in Maine using recent data. We used International Statistical Classification of Diseases and Related Health Problems diagnosis and procedure codes (9th & 10th revisions) to identify deliveries among all hospital discharges in Maine, 2009-2017 (n=109,004), and to categorize deliveries according to prevalence of OUD and selected medical conditions. We ran log-binomial regression to assess trends in OUD delivery across study years, and calculated prevalence ratios (PR) and 95% confidence intervals (CI). The mean prevalence of OUD at delivery hospitalization in Maine increased from 21.6 in 2009 to 38.0 in 2017; linear trend p-value<.01. The mean relative increase per year was 5.8%[95%CI:4.5%,7.2%]. The following were more common among women with OUD vs without OUD: anxiety, 5.1% vs 1.9%, PR=2.7[2.3,3.1]; major depression, 4.0% vs 1.4%, PR=2.9[2.4,3.4]; hepatitis C, 7.6% vs 0.2%, PR=35.2[29.6,41.9]; tobacco/nicotine use 64.0% vs 10.7%, PR=6.0[5.8,6.2]; and cannabis use 5.9% vs. 1.1%, PR=5.5[4.8,6.4]. OUD among deliveries in Maine has increased since 2009 to 1 out of 30 deliveries, and commonly occurs with other medical conditions. Prevention and treatment of OUD among reproductive age women in Maine remains needed.
