Insights
Increased access to opioid use disorder treatment facilities in a county is linked to fewer postpartum hospitalizations for individuals with opioid use disorder. Early postpartum hospitalizations predict later ones, highlighting the need for accessible care.
Area of Science:
- Public Health
- Addiction Medicine
- Perinatal Health
Background:
- The postpartum period presents unique challenges for individuals with opioid use disorder (OUD), including increased risk of health and drug-related problems due to new responsibilities and changing environments.
- This study investigates factors contributing to hospitalization among individuals with OUD during their first year postpartum.
Purpose of the Study:
- To examine county-level and individual-level factors associated with hospitalization in the first year postpartum among individuals with OUD.
- To identify specific risk factors for all-cause, OUD-related, and mental health-related hospitalizations in early and late postpartum periods.
Main Methods:
- A cohort of 1966 individuals with OUD at delivery in Pennsylvania was analyzed using hospital discharge data.
- Multilevel logistic regression models assessed county-level factors (income, rurality, jail rate, OUD treatment facilities, hospital beds) and individual-level factors (demographics, insurance, substance use, mental health conditions).
Main Results:
- 14% (n=280) of individuals experienced at least one hospitalization in the first year postpartum.
- Higher county densities of OUD treatment facilities were associated with significantly lower odds of all hospitalization types in early postpartum (0-42 days), particularly OUD-related hospitalizations.
- Younger maternal age and prior early postpartum hospitalizations were associated with increased odds of later hospitalizations, including mental health-related events.
Conclusions:
- County-level healthcare and drug treatment systems play a significant role in hospitalizations among individuals with OUD postpartum.
- Addressing systemic barriers to accessing OUD treatment and postpartum care is crucial for improving health outcomes and reducing drug-related harms for this population.
Introduction:
During the postpartum period, new parental responsibilities may compound changing social, community, and health care environments to increase risk of health and drug-related problems. This study examines both county-level and individual-level factors associated with hospitalization among individuals with opioid use disorder (OUD) throughout the first-year postpartum.
Methods:
A cohort of individuals with OUD at delivery were identified in Pennsylvania hospital discharge data (n = 1966). Multilevel logistic regression models examined county-level (median household income, rurality, jail rate, OUD treatment facilities, hospital beds) and individual-level (demographics, insurance, tobacco use, other substance use disorders, mental health conditions) factors associated with inpatient hospitalizations (all-cause, OUD-related, mental health-related) in the early (0-42 days) and late (43-365 days) postpartum periods.
Results:
In total, 280 individuals (14%) with OUD had at least 1 hospitalization in the first-year postpartum. After adjustment, higher county densities of OUD treatment facilities were associated with lower odds of all 3 types of hospitalizations in early postpartum, including 80% to 86% reduced odds of OUD-related hospitalizations for those in counties with the 3 highest quartiles of treatment facility densities compared with the lowest quartile. These associations did not remain significant in late postpartum. All maternal age groups, compared with those aged 25 to 29, had increased odds of a mental health-related hospitalization in early postpartum, and the youngest age group (17-24 years) had increased odds in late postpartum. Experiencing any hospitalization from 0 to 42 days postpartum was positively associated with all 3 types of hospitalizations in late postpartum.
Discussion:
County health care and drug treatment systems are associated with hospitalizations among individuals with OUD throughout the first-year postpartum. Addressing policy, sociocultural, and structural barriers to accessing these services should be a priority for improving postpartum health and reducing drug-related harms in this period.
