Background and Aims A Obstetric-specific recovery tool (ObsQoR-10) were developed to assess the quality of recovery (QoR), however, its correlation with maternal outcomes has not been investigated. We correlated the ObsQoR-10 at post-Caesarean 24 hours with validated assessments of Breastfeeding self- efficacy (BSES-SF), Hospital Anxiety and Depression Scale (HADS), Edinburgh postpartum depression scale (EPDS), pain catastrophizing scale (PCS), and EQ-5D-3L at day 7.

Methods Post-Caesarean questionnaires were administered to parturients after elective caesarean delivery at KK Hospital in Singapore at (i) 24 hours (ObsQoR-10, HADS, EQ-5D-3L, EPDS, PCS); (ii) 48 hours (ObsQoR-10, EQ-5D-3L); (iii) 7 days after Caesarean delivery (ObsQoR-10, BSES-SF, EQ-5D-3L, EPDS).

Results 158 patients completed the questionnaires between Sep 2022 and Apr 2023. ObsQoR-10 demonstrated significant internal consistency (Cronbach’s- alpha=0.89) but only limited test-retest reliability (Pearson’s r=0.26). The ObsQoR-10 score had moderate correlation with EQ-5D-3L global health visual analogue scale (VAS) at post-Caesarean 24 hours (Pearson’s r=0.31) but only weak correlation at 48 hours and 7 days (Pearson’s r=0.28, 0.18 respectively). It had moderate-to-high degree of correlation with PCS subscales on rumination (Pearson’s r=0.51), magnification (Pearson’s r=0.43), helplessness (Pearson’s r=0.47) at 24 hours. ObsQoR-10 exhibited moderate correlation with measures of anxiety (Pearson’s r=0.43) and depression (Pearson’s r=0.49) especially at 24 hours as measured by HADS and EPDS (Pearson’s r=0.41) but the degree of correlation decreases at day 7 (Pearson’s r=0.31).

Conclusions These results suggest ObsQoR-10 could be used in assessing the QoR in domains of pain catastrophizing-rumination, depression, pain, and quality of life in the Asian population especially within the first 24 hours after delivery.
