Validity and Reliability of the Turkish Quality of Recovery-15 (QoR-15T) Scale in Cardiac Surgery Patients: A Prospective Observational Cohort Study

The objective of this prospective observational cohort study is to evaluate the validity, reliability, and responsiveness of the Turkish version of the Quality of Recovery-15 (QoR-15T) scale in adult patients undergoing elective cardiac surgery. While the QoR-15T has been validated for general surgery in Turkey, its performance remains to be established in high-risk cardiac surgery populations involving cardiopulmonary bypass and intensive care stays.Approximately 150 patients at Kocaeli City Hospital will be enrolled. The study will compare the patients' QoR-15T scores-recorded preoperatively and on the 7th postoperative day-with the Global Recovery Visual Analog Scale (VAS) to determine construct validity.
