Using ObsQoR-10 to compare recovery after births with and without postpartum hemorrhage

Comparing the Obstetric Quality of Recovery-10 (OBS-QoR-10) in Patients With and Without Postpartum Hemorrhage: A Matched Case-control Study

Observational Samuel Lunenfeld Research Institute, Mount Sinai Hospital · NCT07199803

This project uses the ObsQoR-10 survey to see if people who have postpartum hemorrhage after vaginal or cesarean birth report different recovery, breastfeeding, and wellbeing than those who do not.

What this trial studies

Researchers at Mount Sinai Hospital will enroll people aged 18 or older who delivered by vaginal or cesarean birth with neuraxial analgesia and can complete English surveys, and will separate them into PPH and non-PPH cohorts based on quantitative blood loss, transfusion, ICU transfer, or major interventions. Participants will complete the Obstetric Quality of Recovery-10 (ObsQoR-10) patient-reported outcome tool to measure recovery, breastfeeding status, and overall wellbeing after delivery. This observational comparison aims to identify factors linked to poorer recovery in the context of postpartum hemorrhage. Findings are intended to help incorporate patient-reported recovery measures into PPH outcome sets and guide postpartum support.

Who should consider this trial

Good fit: Adults (≥18) who delivered at Mount Sinai Hospital by vaginal or cesarean delivery with neuraxial analgesia, can communicate in English, and meet the study's PPH (e.g., QBL ≥1000 mL, transfusion, ICU transfer, or major intervention) or non-PPH (QBL <500 mL, no transfusion, no elevated care) criteria.

Not a fit: Patients with pre-existing psychiatric disorders affecting recovery assessment, those with severe non-PPH obstetric complications, non-English speakers, people with overdistended uteri or prior documented PPH, and those who delivered elsewhere are unlikely to receive direct benefit from participation.

Why it matters

Potential benefit: If successful, the findings could help clinicians identify people at risk of poor recovery after PPH and improve postpartum support for wellbeing and breastfeeding.

How similar studies have performed: ObsQoR-10 has been used successfully to measure postpartum recovery after cesarean and vaginal births, but applying it specifically to compare outcomes in PPH versus non-PPH populations is relatively novel.
