We sought to identify risk factors (including SDOH risk factors) for 180\u2010day postpartum readmissions related to opioid use among individuals without a documented diagnosis of opioid use at delivery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We performed a retrospective cohort study using 2016\u20132021 data from the Nationwide Readmissions Database. Delivery hospitalizations and subsequent 180\u2010day postpartum readmissions with a new opioid\u2010use diagnosis were identified. Newly documented opioid use was defined as opioid dependence, abuse, or overdose documented at readmission without evidence of opioid use disorder at or prior to delivery. SDOH exposures were categorized into domains reflecting education\/employment, physical environment, and social factors using International Classification of Diseases (ICD)\u201010 codes. Temporal trends in opioid use\u2013related postpartum readmissions were evaluated using joinpoint regression to estimate average annual percent change (AAPC) with 95% confidence intervals (CIs). Multivariable logistic regression was used to estimate associations between SDOH and 180\u2010day newly documented opioid use readmission, adjusting for demographic and clinical factors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among 10,278,674 delivery hospitalizations, 3129 individuals (3.0 per 10,000) experienced a postpartum readmission with newly documented opioid use. The rate of 180\u2010day postpartum opioid\u2010related readmission declined from 3.7 to 2.2 per 10,000 delivery hospitalizations between 2016 and 2021 (AAPC, \u221210.4%; 95% CI, \u221213.5% to \u22127.8%). In unadjusted models, education\u2010 or employment\u2010related SDOH (odds ratio [OR], 6.26; 95% CI, 2.70\u201314.51), SDOH related to the physical environment, housing, or economic circumstances (OR, 20.93; 95% CI, 14.81\u201329.57), and social SDOH (OR, 4.09; 95% CI, 2.51\u20136.65) were associated with opioid\u2010related readmission. In adjusted models, only SDOH related to the physical environment, housing, or economic circumstances remained independently associated with opioid\u2010related readmission (adjusted odds ratio [aOR], 4.87; 95% CI, 3.35\u20137.09).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Although postpartum readmissions for newly documented opioid use have declined nationally, individuals experiencing adverse physical environment\u2013related SDOH remain at significantly elevated risk.
