Development and evaluation of an obstetric quality-of-recovery score (ObsQoR-11) after elective Caesarean delivery.

Abstract

BACKGROUND: Whilst validated quality-of-recovery (QoR) tools exist for general surgery, there is no specific obstetric equivalent. We aimed to develop and evaluate a modified QoR score after elective Caesarean delivery.METHODS: Twenty-two obstetric specific items were selected following review and modification of the QoR-40 survey by 16 experts and interviews with 50 stakeholders. Item selection was based on relevance to Caesarean delivery and endorsement by >66% of stakeholders. Items were tested on women pre-delivery, at 24 h, and 25 h post-delivery. An 11-item obstetric-specific QoR score (ObsQoR-11) was created based on correlation with a numerical rating scale (NRS) of global health status (r>0.20) at all time points. Reliability, responsiveness, acceptability, and feasibility were tested.RESULTS: One hundred and fifty-two women responded to the 22-item questionnaire pre-delivery (complete in 146), 100 at 24 h, and 10 at 25 h. The ObsQoR-11 correlated with the global health status NRS (r=0.53; 95% confidence interval: 0.43-0.62; P<0.0001) and discriminated good vs poor recovery (NRS score =70 vs <70 mm) at 24 h. There was a negative correlation between the ObsQoR-11 score at 24 h and hospital length of stay (r=-0.39; P=0.003). ObsQoR-11 was reliable (internal consistency: 0.85; split-half 0.76; test-retest intra-class correlation coefficient ri>0.6 in 82% of items) and responsive (Cohen effect size: 1.36; standardised response mean: 0.85). A longer 22-item ObsQoR had high (97%) completion rates and short (median: 2 min) completion times.CONCLUSIONS: The ObsQoR-11 provides a valid, reliable, and responsive global assessment of recovery after elective Caesarean delivery.
