The Investigation of validity and security of recovery quality score in Turkish patient population

Quality of recovery after anesthesia and surgery is an important measure of the health status of the patients. In this thesis study, we attempted to develope a valid an reliable and responsive and objective measure of quality of recovery after and surgery comparing with VAS, MAS and EQ-5D in Turkish patient population after adopting to Turkish. Following standard anesthesia, EQ 5D, VAS, QoR-40 Modified Aldrete Score were asked to rate patients ages greater than 18, at preoperative period, whwn patients are in the recovery room 30 minutes after surgery and we repeated the test 24 hours after the surgery. Exclusion criterias were, patients poor ability of understanding Turkish, severe psychological disorders, severe alcohol or substance abuse or postoperative severe medical problems, and day-case surgeries. Results were analysed statistically. Results of 108 patients were analysed. Patients told that they don?t have negative experience for rating the questionnaire. The questionnaires were completed at the preoperative period for 16.3±9.2 minutes, in the recovery room for 22.4±11.4, minutes, and at the postoperative period for 14.2±8.5 minutes. As a result, the 40 item questionnaire QoR-40 has a good reliability, validity and internal consistency (p<0.001) in Turkish patient population. The questionnaire could be appilied to different types of surgical patients in a short time without refusal. Construct validity was supported by lower scores of QoR of women compared to men. (p<0.05) There was a good convergant validity between QoR-40 and VAS in the recovery room (p=0.020 rho=0.226) and after 24 hours following surgery. (p=0.18 rho=0.230). EQ 5D and QoR-40 was not found correlated after anesthesia and surgery. Test ?retest reliability was found only for comfort domain. . As a result QoR-40 is an onjective measure of recovery after anesthesia and surgery and could be a useful ?end-point? in perioperative clinical studies.
