Use of Opioid-Sparing Protocols and Perceived Postpartum Pain in Patients with Opioid Use Disorder and Chronic Prenatal Opioid Exposure.

ABSTRACT

INTRODUCTION: Opioid-sparing protocols reduce postpartum opioid prescribing in opioid-naïve patients; however, patients with opioid use disorder (OUD) and complex pain needs who may benefit from these protocols are typically excluded from them. We assessed postpartum pain experiences of patients with OUD and chronic prenatal opioid exposure after implementation of an opioid-sparing protocol. METHODS: A phone survey assessed postpartum pain experiences for people with chronic prenatal opioid exposure who delivered between January 2020 and August 2021 at an academic hospital. Analyses included descriptive statistics, qualitative content analysis, and a joint display comparing themes. RESULTS: Of 25 patients, 18 (72%) participated; most were non-Hispanic White (100%, 18/18), publicly insured (78%, 14/18), multiparous (78%, 14/18), with OUD (100%, 18/18). No patients with a vaginal birth received an opioid prescription; half (4/8) with a cesarean birth received one at discharge. Over one-third (7/18, 39%) reported poor pain control (≥ 5/10) in the hospital and one week post-discharge; scores were higher for cesarean versus vaginal birth. Qualitative sub-analyses of open-ended responses revealed patient perceptions of postpartum pain and treatment. The most effective strategies, stratified by birth type and pain level, ranged from non-opioid medications for vaginal births and minor pain to prescription opioids for cesarean births and moderate-to-intense pain. DISCUSSION: Postpartum opioid prescribing for patients with chronic prenatal opioid use was low for vaginal and cesarean birth following implementation of an opioid-sparing protocol. Patients with OUD reported good pain management with opioid-sparing pain regimens; however, many reported poorly controlled pain immediately postpartum. Future work should assess approaches to postpartum pain management that minimize the risks of opioid medication-particularly in at-risk groups.

What is already known on this subject? Opioid-sparing protocols can reduce postpartum opioid prescribing in opioid-naïve patients; however, there are currently no clear guidelines for opioid prescribing for people with opioid use disorder (OUD) in the postpartum period.What this study adds?Postpartum opioid prescribing for patients with chronic prenatal opioid use was less than the national average and one-third of patients reported poor pain control. Opioid-sparing protocols postpartum should be expanded to patients with OUD to improve pain control and minimize risks associated with opioid medication.
