The quality of recovery score QoR-40 is a recovery-specific and patient-rated questionnaire to assess the early postoperative health status of patients. However, the Japanese version of the QoR40 has not been established. The aim of this study was to validate the quality of recovery 40 Japanese version (the QoR-40J) according to the methods adopted by the International Quality of Life Assessment (IQOLA) project.
After obtaining ethics committee approval and consent, 192 general and otological surgical patients were studied. The QoR-40J was used to measure postoperative health status on day 3 and 1 month after surgery. The level of quality of life was also evaluated using a general, health-related quality of life questionnaire (Short-Form Health Survey-36 sub-scales; SF-36), at 1 month after the surgery. Psychometric analysis including the following properties: test-retest reliability, internal consistency, predictive validity, and measurement of responsiveness, was performed to validate the QoR-40J.
Test-retest reliability (Spearman's correlation coefficient) and internal consistency (Cronbach's α) of the QoR-40J were 0.887 and 0.91, respectively. A significant relationship was observed between the total QoR-40J score and duration of hospitalization (r = -0.291) and between the global QoR-40J score and postoperative scores of the SF-36 sub-scales (physical function, ρ = 0.287; vital score, ρ = 0.349). The standardized mean of the QoR-40J, a measurement of responsiveness, was 0.70.
The results of the psychometric analysis indicated that the QoR-40J has characteristics of acceptable validity, reliability, and responsiveness in clinical practice in Japan. The QoR-40J may aid in evaluating the quality of recovery after surgery or the quality of methods of anesthesia.

- "Responsiveness, or sensitivity to clinical change, was measured by evaluating the standardized response mean (SRM). The SRM is calculated by dividing the mean change in the score by the standard deviation (SD) of the change [13,14]. "

ABSTRACT: The Quality of Recovery-40 questionnaire (QoR-40) is a self-rated questionnaire used to assess the postoperative recovery quality and health status of patients in the early stages following surgery; however, there is no Turkish version of the QoR-40. The aim of this study was to assess the reliability, validity, and responsiveness of the Turkish version of the QoR-40 (QoR-40 T).
After the approval of the ethics committee, a total of 137 patients completed the questionnaire during the preoperative period, on the third day, and one month after surgery. The quality of life was evaluated by using a health-related quality of life questionnaire (Short-Form Health Survey-36; SF-36) on the third day and one month after surgery. Reliability, feasibility, and validity were assessed to validate the QoR-40 T.
The Cronbach's alpha of the global QoR-40 T on the third day after surgery was 0.936. A positive moderate correlation was obtained between the physical comfort, emotional state, physical independence, and pain dimensions of the QoR-40 T and the physical component summary, mental health, physical functioning, and bodily pain subscales of the SF-36 on the third day after surgery, respectively (physical comfort - physical component summary, rho = 0.292, p = 0.001; emotional state - mental health, rho = 0.252, p = 0.003; physical independence - physical functioning, rho = 0.340, p < 0.01; pain - bodily pain, rho = 0.381, p < 0.01). The standardized responsive mean of the total QoR-40 T was 0.62.
The QoR-40 T showed satisfactory reliability and validity in evaluating the quality of recovery after surgery in the Turkish population.

ABSTRACT: A system of preoperative anesthesia evaluation clinic can provide a chance to evaluate the surgical patients effectively and to obtain an informed consent for anesthesia from the patients with their family. To organize this system effectively, communications with the doctors, nurses and comedical staffs in other departments/ sections are necessary. Postoperative anesthesia evaluation can be performed to gather information about patient satisfaction and postoperative anesthesia-related complications. This information can be used as a feedback to each anesthesiologist to improve anesthetic management. Establishment of anesthesia evaluation clinic can improve the safety and quality of anesthesia as well as efficiency of hospital management.

ABSTRACT: After introducing "BOKUTOH enhanced recvery after surgery (ERAS)" protocol for colorectal surgery in our hospital, the hospital stay after surgery was reduced from 10 days to 7. However, the patients' quality of life (QOL) throughout the perioperative period was not quantified. We assessed the QOL of these patients by using QoR-40J and SF-36v2J (Japanese versions of QoR-40 and SF-36v2) questionnaires.
Twenty-seven colorectal cancer patients undergoing surgery and "BOKUTOH ERAS" protocol management were asked to answer both QoR-40 J and SF-36v2J questionnaires pre- and post-operatively. The scores were evaluated by using Mann-Whitney U-test.
From preoperative score (183.5), the scores of QoR-40 J differed significantly on post-operating day (POD) 1 and POD3 (150.9 [15.7] and 168.1 [17.5] points, respectively). Before leaving the hospital (POD6) and after one month from surgery, both QoR40 J and SF-36v2J scores were similar to preoperative ones.
Under "BOKUTOH ERAS" protocol management, patients who had had colorectal surgery were able to recover their QOL within 6 days. Thus, leaving hospital by 7 days after surgery was appropriate to our patients.
