Measured using the self-reported quality of recovery score (QoR)-15. The 15-item questionnaire patient satisfaction survey over the last 24 hours on 11 point Likert scale for positive items, 0 = "none of the time" to 10 = "all of the time"; for negative items the scoring was reversed. Total score range 0 to 150, with higher scores indicating better quality of recovery.
