Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Total Sleep Time (TST) on the Night Before Surgery | Night before surgery | Total sleep time measured by a wrist-worn sleep monitoring device (Huawei smart band) during the night before brain tumor surgery. TST is defined as the total duration of sleep from sleep onset to final awakening, reported in minutes. |
| Secondary | Subjective sleep quality | Preoperative day 1, Postoperative days 1-3 (assessed at 8:00-10:00 AM) | Richards-Campbell Sleep Questionnaire (RCSQ) score. The RCSQ is a 5-item visual analog scale assessing sleep depth, sleep onset latency, awakenings, time spent awake, and overall sleep quality. Each item scored 0-100, total score is the mean of 5 items, range 0-100, higher scores indicate better sleep. |
| Secondary | Objective sleep quality | Postoperative night 0 (20:00 to 08:00 next day) and Postoperative night 2 (20:00 to 08:00 next day) | Total sleep time measured by a wrist-worn sleep monitoring device (Huawei smart band) during the night of postoperative day 0. Reported in minutes. |
| Secondary | Time to Extubation | Immediately after surgery | Time from the end of surgery to extubation, defined as removal of the endotracheal tube. Reported in minutes. |
| Secondary | Time to Awakening | Immediately after surgery | Time from the end of anesthesia to the first response to verbal command. Reported in minutes. |
| Secondary | Perioperative Anxiety Visual Analog Scale (VAS-A) Score | Perioperative [Upon entry to the operating room (before induction of anesthesia), and 1 hour after surgery] | Anxiety Visual Analog Scale (VAS-A) score. The VAS-A is a 100-mm horizontal line anchored at 0 (no anxiety) and 100 (worst possible anxiety). The participant marks a point on the line corresponding to their anxiety level. Higher scores indicate greater anxiety. VAS-A score assessed upon entry to the operating room (before induction of anesthesia) and 1 hour after surgery. |
| Secondary | Postoperative Hospital Anxiety and Depression Scale (HADS) Score | Postoperative day 1 and 3 (assessed at 8:00-10:00 AM) | The Hospital Anxiety and Depression Scale (HADS) is a 14-item self-rated questionnaire comprising two 7-item subscales: anxiety (HADS-A) and depression (HADS-D). Each item is scored from 0 to 3. Each subscale score ranges from 0 to 21, with higher scores indicating greater symptom severity. |
| Secondary | Postoperative pain measured by Pain Numeric Rating Scale (NRS) score | 1 hour after surgery, 24 hours, 48 hours and 72 hours after surgery. | Pain Numeric Rating Scale (NRS) score. The NRS is an 11-point scale ranging from 0 (no pain) to 10 (worst possible pain). Higher scores indicate greater pain intensity. |
| Secondary | Postoperative Quality of Recovery-15 (QoR-15) | Postoperative day 1 | Quality of Recovery-15 (QoR-15) score. The QoR-15 is a 15-item questionnaire assessing postoperative recovery across physical comfort, emotional state, and physical independence. Each item scored 0-10, total range 0-150, higher scores indicate better recovery quality. |
| Secondary | Incidence of Postoperative Delirium | Within 3 days after surgery (assessed twice daily) | Postoperative delirium will be assessed using the 3-Dimensional Confusion Assessment Method (3D-CAM). The 3D-CAM is a structured diagnostic interview that determines the presence or absence of CAM-defined delirium. Delirium incidence is the number of participants with at least one positive 3D-CAM assessment. |
