Brief summary

The main objective of this study is to establish the postoperative pain pathways observed from D1 to D7 in the context of the current management after orthopedic, digestive, obstetrics and gynecology, urology, neurosurgery, vascular and thoracicn surgeries.

Detailed description

The secondary objectives of this study are: A. To assess the incidence of Post-Surgical Chronic Pain (PSCP) Chronic 3 months post intervention. B. To asses the incidence of neuropathic type pain (DN4 Questionnaire) at 3 months post intervention. C. To study the potential links between pain trajectories and the presence or absence of PSCP. D. To study the potential links between the presence or absence of PSCP and known risk factors for PSCP (patient-related data, data on the surgery, anesthesia data).

Interventions

OTHERTelephone conctact at 3 months

Patients will be contacted at 3 months post-surgery for pain questionnaires.

Patients will evaluate their pain levels via a verbal numerical scale on days 1(or-1), 2, 3, 4, 5, 6 & 7.

Patients are required to fill out the HADS and PCS questionnaires between on day -1 or +1.

Design outcomes

Primary

MeasureTime frameDescription
The pain trajectory for the first 7 post-operative days.Day 7 post-surgeryThe pain trajectory is the vector of 7 verbal numerical pain estimates (from 0 to 10) taken over 7 days (days 1 (or -1), 2, 3, 4, 5, 6 & 7). Day 0 is the day of surgery.

Secondary

MeasureTime frame
Since the surgery, do you have persistent pain? yes/nomonth 3
