Research review (peer-reviewed)abstract
- Background.Several rating scales have been developed to measure quality of recovery aftersurgery and anaesthesia, but the most extensively used is the QoR-40, a 40-itemquestionnaire that provides a global score and subscores across five dimensions: patientsupport, comfort, emotions, physical independence, and pain. It has been evaluated in avariety of settings, but its overall psychometric properties (validity, reliability, ease of use,and interpretation) and clinical utility are uncertain.Methods.We undertook a quantitative systematic review of studies evaluatingpsychometric properties of the QoR-40. Data were combined in meta-analyses usingrandom effects models. This resulted in a total sample of 3459 patients from 17 studiesoriginating in nine countries.Results.We confirmed content, construct, and convergent [pooled r¼0.58, 95% confidenceinterval (CI): 0.51–0.65] validity. Reliability was confirmed by excellent intraclass correlation(pooleda¼0.91, 95% CI: 0.88–0.93), test–retest reliability (pooled r¼0.90, 95% CI: 0.86–0.92), and inter-rater reliability (intraclass correlation¼0.86). The clinical utility of theQoR-40 instrument was supported by high patient recruitment into evaluation studies(97%), and an excellent completion and return rate (97%). The mean time to completethe QoR-40 was 5.1 (95% CI: 4.4–5.7) min.Conclusions.The QoR-40 is a widely used and extensively validated measure of quality ofrecovery. The QoR-40 is a suitable measure of postoperative quality of recovery in arange of clinical and research situations.Keywords:health status; meta-analysis; outcomes
