Abstract
BACKGROUND: Quality of recovery (QoR) after surgery is often focused on morbidity, mortality and physiological changes, while well-being and emotional state are other important aspects that are often ignored. QoR is poorly investigated in clinical settings and a psychometrically tested questionnaire, QoR-15, has recently been developed. QoR-15 has not been validated for Swedish conditions. The aim of this study was to translate, adapt and validate QoR-15 to Swedish conditions (QoR-15swe). METHODS: A translation and cultural adaption was performed resulting in a Swedish version of the instrument, QoR-15swe. Patients answered the QoR-15swe before surgery, 24 and 48 h after surgery. Feasibility, validity, reliability and responsiveness of the QoR-15swe were evaluated. RESULTS: The QoR-15swe was feasible in 85.5% of the eligible patients. Construct validity was good, with significant correlations between QoR-15swe score and, ASA-PS class, grade of surgery, length of surgery and time in the post-anaesthesia care unit. The instrument demonstrated good internal consistency with an inter-item Cronbach's α of 0.83-0.87, and inter-dimension Cronbach's α was acceptable 0.71-0.76. Test-retest repeatability was also good with Cronbach's alpha > 0.99 and an interclass correlation coefficient of 0.992 (CI: 0.981-0.997). There were no floor and ceiling effects. Responsiveness assessed by Cliff's effect size was -0.23 indicating a moderate ability to detect change at 24 h postoperatively. CONCLUSION: We have translated and culturally adapted the QoR-15 into Swedish. The score demonstrated acceptable validity, reliability and responsiveness. The QoR-15swe is a clinically acceptable and feasible outcome measure after surgery in a Swedish population.
