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.
Study Type
OBSERVATIONAL
Enrollment
200
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.

SF-36 Physical Component Summary (PCS) score at 3 months
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.
Time frame: 3 months after index surgery (day 90 to day 120)
SF-36 Mental Component Summary (MCS) score at 3 months
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.
Time frame: 3 months after index surgery (day 90 to day 120)
Persistent postsurgical pain at 3 months
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.
Time frame: 3 months after index surgery (day 90 to day 120)
