Obstetric pain management for pregnant women with opioid use disorder: A qualitative and quantitative comparison of patient and provider perspectives (QUEST study).

BACKGROUND AND AIM: Patients with opioid use disorder (OUD) may experience inadequate pain management especially during childbirth. This study assessed and compared patient and provider perspectives on analgesia during and after delivery in women with OUD. DESIGN: Prospective cohort, mixed method design including semi-structured interviews and structured surveys with pregnant or recently pregnant patients (n = 17) and provider (n = 15) groups. SETTING: Prenatal clinics and hospital postpartum units. PARTICIPANTS: Patients were pregnant women with OUD currently treated with methadone (n = 1) or buprenorphine (n = 16). Providers were obstetricians (n = 5), obstetric nurses (n = 5) and anesthesiologists (n = 5). MEASUREMENTS: Validated questionnaires were completed by both groups; patient interviews were conducted during the third trimester and at 5 days post-delivery. Patient topics included pain management preferences, analgesia satisfaction and attitudes toward pain. Provider topics included labor and postpartum pain management perspectives. Interviews were independently coded and qualitatively analyzed for major themes. FINDINGS: Five major themes emerged from patient interviews: (1) neuraxial blockade was endorsed for labor pain; (2) otherwise, limited pain control options were perceived; (3) no consensus around use of opioids for pain; (4) non-opioid options should be available; and (5) provider communication and health-care system issues act as barriers to adequate pain management. Provider perspective themes included the following: (1) unique challenges in pain management for patients with OUD; (2) confusion on how to plan for and make perinatal adjustments to medication for OUD; (3) discrepant views on use of opioids for pain management; (4) endorsement of non-pharmacological and non-opioid options; and (5) need for improved provider collaboration in developing pain management plans. CONCLUSIONS: Patients with opioid use disorder and health-care providers prioritize pain management during and after childbirth, but have discrepant views on use of opioids and other pain management options. Inadequate care coordination and discrepancies in opinions need to be addressed both within care teams and between patients and providers. Clinicians would benefit from better evidence to guide clinical care of patients with OUD for patient-centered pain management.

Associations between postpartum pain, mood, and maternal-infant attachment and parenting outcomes.

Pain and depression are interrelated, and worse postpartum pain has been associated with postpartum depression. It remains unclear whether improved pain and mood after delivery can also improve maternal parenting. Few studies have examined relationships between postpartum pain and negative mood (anxiety or depression) or their effects on parent-infant relationship outcomes. The purpose of this study was to explore the relationships between postpartum pain, mood, parent-infant attachment, parenting self-efficacy, and infant development. This was a prospective longitudinal observational pilot study of nulliparous women enrolled at the third trimester and presenting for labor and delivery at term gestation. Baseline third trimester assessments included validated inventories of pain (the brief pain inventory, BPI), depression (the Edinburgh postnatal depression screen, EPDS), anxiety (the state trait anxiety inventory, STAI), multidimensional scale of perceived social support (perceived social support scale, MSPSS) and perceived stress scale (PSS). Demographic and labor characteristics were recorded. At 6 weeks and 3 months postpartum, self-reported assessments included EPDS, STAI, BPI, maternal parent infant attachment scale (MPAS), and perceived maternal parenting self-efficacy (PMP-SE). Child development outcomes were assessed at 6 weeks and 3 months using the Ages and Stages Questionnaire (ASQ). Univariable linear regression assessed the relationships between pain and parenting outcomes (MPAS and PMP-SE), including potential interactions between pain and mood for parenting outcomes. Generalized linear modeling was used to explore the relationships between postpartum pain, parenting outcomes, and child development outcomes. Of 187 subjects, 87 had complete data on parent-infant attachment and parenting self-efficacy data at 3 months. Lower "pain right now" scores (BPI) on postpartum day 1 was associated with higher maternal-infant attachment (MPAS) at 6 weeks postpartum (Estimate - 1.8, 95% CI - 3.4 to - 0.2, P < 0.03) but not at 3 months (Estimate 0.23 95% CI - 1.1 to 1.6, P = 0.7). Higher depression (EPDS) scores at 6 weeks were also associated with lower MPAS scores at 6 weeks (Estimate - 1.24, 95% CI - 2.07 to - 0.40, P = 0.004). However, there was no evidence that the relationship between pain and MPAS varied by depression score at 6 weeks (P = 0.42). Pain scores at baseline, six weeks, or three months did not correlate with parenting outcomes (MPAS, PMP-SE) at six weeks or three months. Results of the generalized linear modeling revealed relationships between pain, age, anxiety (STAI), and depression (EPDS) predictors, and the outcomes of parenting (MPAS, PMP-SE) and gross motor and personal-social (ASQ) aspects of infant development. There is a pattern of association between worse postpartum pain, anxiety, and depression with worse parenting outcomes. Depression and pain may also affect infant development, but future work is required to replicate and characterize these potential relationships.
