Emergencies, Postoperative Pain, Quality of Life
Conditions
Brief summary
The aim of this study is to evaluate the impact of implementing a national surgical emergency classification system in the emergency operating room in Nice on patients' quality of life and persistent pain 3 months after surgery. This work is a local ancillary study of the CLASSE trial conducted by the French Society of Anaesthesia and Intensive Care Medicine (SFAR). The primary hypothesis is that implementing a decision-support tool incorporating recommended time-to-surgery targets will improve patients' health status 3 months after surgery, as reflected by higher SF-36 Physical Component Summary (PCS) scores, a lower incidence of persistent and neuropathic pain, and greater patient satisfaction.
Interventions
OTHERUsual-practice emergency-surgery triage
Participants were included locally in CLASSES at CHU de Nice from March 9 to March 22, 2026, when emergency surgical cases were triaged according to usual local practice. No exposure was assigned by the investigators.
OTHERNational surgical-emergency classification-based triage
Participants are included during the corresponding weeks of March 2027, after local implementation of the national surgical-emergency classification and its recommended time-to-surgery targets. No individual exposure is assigned by the investigators.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| SF-36 Physical Component Summary (PCS) score at 3 months | 3 months after index surgery (day 90 to day 120) | PCS calculated from SF-36 responses using the validated scoring algorithm prespecified in the analysis plan. Higher scores indicate better physical health-related quality of life. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| SF-36 Mental Component Summary (MCS) score at 3 months | 3 months after index surgery (day 90 to day 120) | MCS calculated from SF-36 responses using the validated scoring algorithm prespecified in the analysis plan. Higher scores indicate better mental health-related quality of life. |
| Persistent postsurgical pain at 3 months | 3 months after index surgery (day 90 to day 120) | Proportion of participants reporting current pain in or around the operated area or relevant territory that was absent before surgery or was clearly worsened or changed after surgery. |
