Psychometric evaluation of the modified quality of recovery score for the postanaesthesia care unit (QoR-PACU2)—A prospective validation study
Authors' conclusion
The QoR-PACU2 assesses self-reported QoR after surgery in the PACU. Measures of feasibility, validity, and reliability were consistently high. Measures of responsiveness were moderate, which might be attributable to the heterogeneity of the study population.
Study context
- Population
- Adults scheduled for non-cardiac surgery with GAincluded in final analysis

- Outcome
- Psychometric properties of QoR-PACU2
Methodological detailsQoR-PACU2 administered before surgery and in post-anesthesia care unit (PACU) at the time of the decision to discharge

Performance
As reported in the abstract
- Cronbach's alpha
- 0.70 (95% CI 0.66-0.75)
- Intra-class correlation coefficient, intra-rater reliability
- 0.86 (n = 24; 95% CI 0.70-0.94, p < 0.001)
- Intra-class correlation coefficient, inter-rater reliability
- 0.94 (n = 31; 95% CI 0.90 to 0.97, p < 0.001)
- Cohen's effect size
- 0.68
- Standardized response mean
- 0.57
Further findings
Construct validity of postoperative QoR-PACU2 sum scores
- Scores differed across categories of sex, perioperative and surgical risk, and modes of airway management
- Duration of anaesthesia and surgery, maximum pain intensity and analgesic requirement in PACU, and PACU LOS inversely correlated with quality of recovery (QoR) in PACU
