Registered outcomes2
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Agreement Between Patient-Reported Pain Intensity (NRS) and Observer-Rated Pain Behavior Score | Postoperative 2, 6, and 24 hours | Observer-rated pain behavior is scored with a standardized behavioral pain assessment adapted from CPOT and FLACC: facial expression, body movements, and vocal expressions, each scored 0-2 (total 0-6; higher scores indicate more pronounced pain behavior). Correlation/agreement with simultaneous NRS scores will be analyzed. |
| Secondary | Association Between Patient-Reported Pain Intensity (NRS) and Analgesic Request | Postoperative 2, 6, and 24 hours | Patients rate their current pain on the Numeric Rating Scale (NRS; 0 = no pain, 10 = worst pain imaginable) and are asked whether they need additional analgesia (yes/no) at each time point. The association/agreement between NRS scores and analgesic request will be analyzed (e.g., point-biserial/Spearman correlation and comparison of NRS scores between patients who do and do not request analgesia). |
