Registered outcomes9
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Postoperative Quality of Recovery-15 (QOR-15) score | postoperative day 1 | The 15-item Quality of Recovery-15 scale assessing postoperative recovery quality, total score ranges from 0 to 150; higher scores indicate better postoperative recovery quality. |
| Secondary | Quality of Recovery-15 (QOR-15) score | At postoperative day 2 and postoperative day 3, assessed up to 30 days after randomization. | The 15-item Quality of Recovery Scale (QoR-15). Total score ranges from 0 to 150. Higher scores indicate better postoperative recovery quality. |
| Secondary | Incidence of intraoperative awareness assessed by Brice interview | At postoperative day 1, postoperative day 2 and postoperative day 3, assessed up to 30 days after randomization. | Intraoperative awareness will be screened using the Brice interview questionnaire |
| Secondary | Incidence of postoperative delirium assessed by Confusion Assessment Method (CAM) | At postoperative day 1, postoperative day 2 and postoperative day 3, assessed up to 30 days after randomization. | Postoperative delirium will be screened using the Confusion Assessment Method (CAM). CAM is a validated tool to identify delirium. |
| Secondary | Hospital length of stay assessed by medical chart review | From the date of hospital admission to the date of hospital discharge, assessed up to 30 days after randomization | Hospital length of stay is calculated by reviewing electronic medical records |
| Secondary | Visual Analog Scale (VAS)-rest pain score | At postoperative day 1, postoperative day 2 and postoperative day 3, assessed up to 30 days after randomization. | Visual Analog Scale (VAS) for resting pain. Score ranges from 0 to 10. Higher scores indicate more severe pain. |
| Secondary | Incidence of postoperative nausea and vomiting (PONV) within postoperative 3 days assessed by clinical observation and medical chart review | At postoperative day 1, postoperative day 2 and postoperative day 3, assessed up to 30 days after randomization. | Postoperative nausea and vomiting events are identified through clinical bedside observation and review of electronic medical records. |
| Secondary | Visual Analog Scale (VAS)-activity pain score | At postoperative day 1, postoperative day 2 and postoperative day 3, assessed up to 30 days after randomization. | Visual Analog Scale (VAS) for activity-induced pain. Score ranges from 0 to 10. Higher scores indicate more severe pain. |
| Secondary | Richard-Campbell Sleep Questionnaire (RCSQ) score | At pre-operation, postoperative day 1 and postoperative day 3, assessed up to 30 days after randomization. | Richard-Campbell Sleep Questionnaire (RCSQ). Total score ranges from 0 to 100. Higher scores indicate better sleep quality. |
