The effective management of acute postoperative pain remains a daily challenge despite the organizational efforts made and the techniques put in place.

Thirty percent of patients who undergo surgery suffer from chronic post-surgical pain, of which 5 to 10% are of severe intensity. Many preoperative, intraoperative, and postoperative factors, related to the patient, the surgical procedure, or the anesthetic technique, have been incriminated as risk factors for chronic post-surgical pain. The severity of acute postoperative pain is recognized as one of the risk factors for the occurrence of chronic post-surgical pain on which we can hope to interact during the peri-operative period.

In this cohort study, we wish to define the typologies of postoperative pain trajectories observed from Day 0 to Day 7 and to estimate the proportion of patients with an abnormal resolution of pain in a model of organization such as that of our institution, in classic hospitalization and in ambulatory care.

The study population consists of adult surgery patients at the Nîmes University Hospital, with recruitment based on the operating theater program ffor a predefined list of surgeries.
