Assessment of COVID-19-Driven Changes in an Integrated OBGYN-Addiction Treatment Clinic and Future Implications.

OBJECTIVE: The COVID-19 pandemic prompted healthcare delivery changes, but the associated impacts on substance use disorder treatment outcomes among pregnant and parenting people are unknown. This study aims to (1) describe COVID-19-driven clinical practice changes, (2) evaluate clinic-level visit attendance patterns, and (3) compare patient-level treatment engagement outcomes across 3 COVID-19 pandemic phases in an OBGYN-addiction treatment clinic. METHODS: COVID-19 phases include pre-COVID-19 (August 2019-February 2020), early COVID-19 (March-December 2020), and COVID-19 vaccine (January-July 2021). OBGYN-addiction treatment clinical practice changes were summarized. Clinic-level attended medical provider visits were analyzed. Patient-level treatment engagement outcomes (buprenorphine continuation, visit attendance, and virtual visits) were assessed in a cohort of pregnant and parenting people enrolled in a clinic research registry. Mixed-level logistic regression models determined the relationship between the COVID-19 phases and the patient-level outcomes. RESULTS: The study site made several COVID-19-driven clinical practice changes, including implementing a hybrid virtual/in-person system for medical visits. Clinic-level medical provider appointments increased between the first and second COVID-19 phases and remained high in the third phase. Among participants included in patient-level outcome analyses (N = 27), there were no differences in the early COVID-19 phase compared with the pre-COVID-19 phase in buprenorphine continuation, any visits, or medical visits. There was a decrease in all patient-level outcomes in the COVID-19 vaccine phase compared with pre-COVID-19 ( P < 0.05). Virtual visits increased between the first 2 phases and remained high during the third. CONCLUSION: Within our OBGYN-addiction treatment clinic, implementation of tailored, patient-centered treatment strategies supported clinic- and patient-level treatment engagement throughout the pandemic.

An Integrated Care Model for Pregnant and Postpartum Individuals Receiving Medication for Opioid Use Disorder.

OBJECTIVES: Perinatal opioid use disorder is increasing. Integrated obstetric/addiction care models likely optimize parent-infant dyad outcomes, but the ideal combination of services is unknown. This study (1) describes pregnancy-to-postpartum service utilization by people receiving buprenorphine at an integrated Obstetric/Addiction Clinic and (2) explores the association between service utilization and postpartum buprenorphine continuation. METHODS: This retrospective medical record review study uses research registry data from an outpatient Obstetric/Addiction Clinic. All patients are invited to participate in the research registry. For patients who consent, monthly medical record abstractions are conducted beginning with their first clinic visit to collect demographic, obstetric, and substance use disorder treatment variables. Present analyses included patients who delivered an infant between June 2019 and June 2021, started buprenorphine during pregnancy, and were receiving buprenorphine at delivery. Overall service utilization was the number of services (range 0-12) used between 28-weeks gestation and 12-weeks postpartum. Bivariate analyses and multivariable logistic regression assessed associations between service utilization and buprenorphine continuation. RESULTS: Participants (n = 42) were primarily non-Latinx White (67%) with comorbid psychiatric diagnoses (95%). On average, participants used 6 services; prenatal care, mental health care, and postpartum contraception were most utilized. Overall, 69% of participants continued buprenorphine at 6 months postpartum. This did not differ by level of service utilization (bivariate [ P = 0.07], multivariable [ P = 0.16]). CONCLUSION: Integrated care with a harm reduction focus supports pregnancy-to-postpartum service utilization and buprenorphine continuation in a patient sample at high risk for medication for opioid use disorder discontinuation. Further work is needed to identify evidence-based methods to individualize integrated obstetric/addiction care.
