Validation of Chinese version of a global anesthetic recovery questionnaire: A multicenter observational trial on ObsQoR-11.

ABSTRACT

BACKGROUND: The obstetric quality of recovery (ObsQoR-11) is considered one of the best patient-reported outcome measures of post-cesarean recovery. However, it has been neither validated in Chinese nor evaluated at >24 h after delivery. METHODS: Parturients from three hospitals (n = 279) completed the Chinese ObsQoR-11 at 24 h (T1) and 96 h (T2) after elective cesarean delivery. Convergent validity was assessed by correlation of Chinese ObsQoR-11 with a 100-mm numerical rating scale (NRS) of general health status; discriminant validity of good recovery (NRS ≥ 70-mm); and construct validity by correlation with influential factors to post-cesarean recovery. The reliability and responsiveness were also assessed. RESULTS: The Chinese ObsQoR-11 correlated moderately with the NRS [T1 r = 0.38 (95% confidence interval 0.28-0.48), p < 0.0001; T2 r = 0.43 (95% confidence interval 0.32-0.52), p < 0.0001] and discriminated between good and poor recovery [T1 mean (SD) score 64 (20) vs 49 (17), p < 0.0001; T2 median (IQR) score 81 (66-94) vs. 61 (53-72); p = 0.0002]; weakly correlated with gestational age, successful breastfeeding, and operation time. It was reliable (internal consistency 0.75 (T1) and 0.82 (T2); split-half 0.77 (T1) and 0.85 (T2); test-retest intraclass correlation coefficient r > 0.6 for each item) and responsive (Cohen effect size 0.88; standardized response mean 0.81). CONCLUSION: The Chinese ObsQoR-11may be used for assessing recovery at 24 h and 96 h after cesarean delivery. However, its' cutoff value for good recovery may be lower than that of other versions.
