Official title
Clinical Prediction of Post-surgical Pain: External Validation
Overview
This study aims to externally validate two clinical prediction models for moderate-to-severe acute post-surgical pain and chronic post-surgical pain. This multi-centre, prospective cohort study will be conducted in Denmark and will include adult patients undergoing various types of elective or sub-acute surgical procedures.
Detailed description
Based on sample size calculations for prediction model validation, a total of 482 patients are required validation of the acute post-surgical pain model and 748 (575 + 30% for loss to follow-up) patients are required for validation of the chronic post-surgical pain model. Therefore, we will aim to recruit 748 patients in total.
Primary outcome measures
- Moderate-to-severe acute post-surgical pain [Time frame: First 3 postoperative hours or until discharge from the PACU]
- Chronic post-surgical pain [Time frame: 3 months post-surgery]
Secondary outcome measures (1)
- Severe acute post-surgical pain [Time frame: First 3 postoperative hours or until discharge from the PACU]
