Measuring quality of recovery-15 after day case surgery

Abstract

Background: 'Quality of recovery' scores are patient-reported outcome measures evaluating recovery after surgery and anaesthesia. However, they are not widely used in the clinical or research setting. The Quality of Recovery-15 (QoR-15) is a recently developed, psychometrically tested and validated questionnaire.

Methods: We conducted a prospective study of all adult patients undergoing orthopaedic day case surgery over a period of six months (June 2013-November 2013). Patients completed the QoR-15 score preoperatively, and then were asked to repeat the score by telephone at 24 h, 48 h and seven days after surgery.

Results: 633 patients from a possible 714 (89%) completed the preoperative questionnaire and data from 437 patients who completed scores at all four time points were analysed. Most patients returned to their preoperative score by 48 h, and had exceeded it by seven days. Construct validity was supported by a negative correlation with duration of surgery and total inpatient opioid use. There was also excellent internal consistency (Cronbach's alpha 0.80-0.83).

Conclusion: The QoR-15 is a clinically acceptable and feasible patient-centred outcome measure after day case surgery. The score demonstrated good validity, reliability and responsiveness. However, measurement of the QoR-15 score on the day of surgery may not provide a true baseline value. We suggest one follow-up call at 48 h would enable an adequate patient-centred assessment of postoperative recovery after day case orthopaedic surgery.
