Sažetak

Quality of recovery after anesthesia is an important indicator of patient postoperative
outcomes. Quality of Recovery-40 (QoR-40) is a validated and widely used multidimensional
40-item questionnaire that measures postoperative quality of recovery. The aim of this
study was to perform translation and psychometric validation of the Croatian version of QoR-40,
which included validity, reliability, responsiveness, and clinical acceptability. The QoR-40 and Short
Form-36 (SF-36) questionnaires were administered to patients undergoing general anesthesia for
elective surgery on the day before surgery and on postoperative day 3. The quality of recovery was
also assessed with visual analog scale (VAS) 0-100. Of 192 enrolled patients, 162 completed the
study protocol. Convergent validity assessed by Pearson correlation (r) between the QoR-40 and
VAS scores was 0.68 (p<0.001). There were moderate correlations of QoR-40 with SF-36 Physical
component scale (r=0.521; p<0.001) and with SF-36 Mental component scale (r=0.580; p<0.001).
Construct validity was supported by negative correlation with the length of hospital stay (r=-0.21;
p=0.007) and significant difference in total postoperative QoR-40 scores between patients with
and without postoperative complications (p<0.001). Internal consistency of the global QoR-40
was high (Cronbach’s α=0.93) and of the QoR-40 dimensions it was moderate to high (≥0.714).
Split-half coefficient was 0.87, Cohen’s effect size was 0.81, and standardized response mean was
0.762. Our translated QoR-40 is a valid, reliable and comprehensive questionnaire for measuring
quality of postoperative recovery across surgery spectrum in Croatian population with psychometric
properties similar to the original version.
