Key Points

To identify associations between maternal pain, psychological vulnerabilities, and obstetric factors leading to sub-acute pain after childbirth.
Included women with singleton pregnancy and assessed pain and psychological vulnerabilities using validated questionnaires.
Conducted follow-up at 6 to 10 weeks postpartum with an online survey.
Evaluated pain outcomes based on the presence of postpartum pain lasting for ≥4 weeks.
12.1% of participants developed sub-acute pain.
Higher CSI scores, increased pain relief administrations, and greater blood loss during delivery were associated with increased risk of sub-acute pain.
Use of prostin for labor induction was found to be protective against sub-acute pain.

Abstract

BACKGROUND: Current research primarily concentrates on acute and chronic postpartum pain, while sub-acute pain after childbirth (SAPC) remains a significant but often under-recognized health concern. We determined if pain and psychological vulnerabilities, obstetric factors, and analgesic choices were associated with the development of SAPC. METHODS: We included women with singleton pregnancy. Pain and psychological vulnerabilities were assessed using validated questionnaires (Angle Labor Pain Questionnaire (A-LPQ), Central Sensitization Inventory (CSI), Edinburgh Postnatal Depression Scale (EDPS), Fear Avoidance Components Scale (FACS), Pain Catastrophizing Scale (PCS), Perceived Stress Scale (PSS), State Trait Anxiety Inventory (STAI)). The primary outcome of SAPC, defined as having postpartum pain lasting for ≥4 weeks, was followed up at 6 to 10 weeks postpartum with online survey. RESULTS: Of the 881 patients recruited, 816 completed the postpartum follow-up, with 99 (12.1%) patients having developed SAPC. Having higher CSI score (adjusted odds ratio (aOR) 1.03, 95%CI 1.01-1.04), increased number of pain relief administrations (aOR 1.55, 95%CI 1.23-1.95), use of artificial rupture of membrane and oxytocic for labor induction (aOR 2.72, 95%CI 1.51-4.91), greater volume of blood loss during delivery (every 10-mL increase; aOR 1.02, 95%CI 1.01-1.03), having had third-degree tear during delivery (aOR 4.12, 95%CI 1.28-13.27) and greater infant weight (aOR 1.15, 95%CI 1.02-1.30) were independently associated with greater risk of SAPC. The use of prostin for labor induction was protective against the risk of SAPC (aOR 0.56, 95%CI 0.34-0.93) (Area under the curve (AUC) = 0.73). CONCLUSION: Our center's multivariable model demonstrates moderate predictive performance and may inform the future development and refinement of predictive tools to identify patients at increased risk of SAPC, thereby supporting more timely monitoring and early interventions for postpartum pain management. TRIAL REGISTRATION: This study was registered on clinicaltrials.gov registry (NCT03167905) on 30/05/2017.
