Validity and Reliability of the Iranian Version of the Quality of Recovery-40 Questionnaire

Abstract

Background:Recovery after anesthesia and surgery is a complex process and depends on many factors such as patient, anesthesia and surgery conditions as well pre-existing comorbidities.Objectives:The aims of this study were to translate the 40-item quality of recovery score (QoR-40) into Persian and evaluate its psychometric properties in Iranian patients.Patients and Methods:We enrolled patients candidate for elective general surgery undergoing general anesthesia from July 2013 to December 2013 at Shahid Rajaee Hospital, Qazvin, Iran. Translation was performed based on Beaton’s and Bullinger’s recommendations. Estimates of internal consistency, test-retest reliability, concurrent validity, predictive validity and clinical validity were performed.Results:All estimates of internal consistency were high (Cronbach's alpha = 0.89 for global estimates, subscales between 0.89 and 0.93). All test-retest scores and subscales were between 0.71 and 0.88.The correlation with a recovery visual analogue scale was 0.51, and all subscales correlated significantly with comparable subscales of the SF-36. An exploratory factor analysis found five-components and explained 52% of the variance. A confirmatory factor analysis based on the five-components, yielded good fit statistics (CFI = 0.93).Conclusions:Overall, the Persian version of the QoR-40 was both conceptually and linguistically equivalent to the original English QoR-40. This study revealed that the Persian version of the QoR-40 is a valid and reliable instrument to assess the recovery quality in Iranian patients after surgery.

Predictive Factors Affecting Postoperative Quality of Recovery for Patients Undergoing Surgery

“…This may be because El-Demerdash hospital is a governmental educational hospital that provides treatment with low cost and most of patients who receive treatment in this hospital are from low socio-economic standard who live mainly in rural areas. These results are contradicted with Yaghoobi et al, (2015) [16] who stated that nearly three quarters of patients were from urban areas, while one quarter from rural, and the mean of BMI of patients was 27.14 ± 15.56.…”

“…This result is in accordance with Berg, Kjellgren, Unosson, & Årestedt, (2012) [18] who stated that more than two thirds of patients were employed, but is contradicted with Yaghoobi et al, (2015) [16] who mentioned that more than half of patients under study were divorced or widowed. The results revealed that half of patients were educated (21% secondary, 29% bachelor), while the others were illiterate or read and write.…”

“…The maximum score of the scale is 200 degree which represents excellent quality of recovery from anesthesia and surgery, while the minimum score is 40 and represents extremely poor quality of recovery. The QoR-40 is known to be valid and reliable questionnaire with Cronbach's alpha scores for postoperative QoR-40 subscales ranged from 0.89 to 0.93 and the global QoR-40 had an α value of 0.89 [16].…”

“…This questionnaire was developed by the researchers in an Arabic language based on the review of related literatures [16] to assess postoperative patient's medical data such as type of surgery, date and duration of surgery, type of anesthesia, weight and height (body mass index) and presence of other diseases.…”

“…Nonetheless, measurements obtained from the patients' records are vital for appropriate monitoring of this period. (3) Several assessment instruments of postoperative recovery have been developed. Among these, the Quality of Recovery-40 Item (QoR-40) stands out, because it is widely indicated for this purpose, presents good results regarding its psychometric properties, is the most commonly used in clinical trials and has been translated into several languages.…”
