Characterization of Post-operative Pain Trajectories Over Seven Days and Links With Chronicity

Study Overview
=================
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).

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| The study population<br>The study population consists of adult surgery patients at the Nîmes University Hospital, with recruitment based on the operating theater program for a predefined six month period and for a predefined list of surgeries. The latter list of surgical acts was established according to the Medicalization of Information Systems Progam (PMSI) database. Patients are recruited either the day before or the day after surgery, in their respective departments. Interventions: In hospital pain evaluation In hospital questionnaires Telephone conctact at 3 months | Other: Telephone conctact at 3 months<br>* Patients will be contacted at 3 months post-surgery for pain questionnaires.<br>Other: In hospital pain evaluation<br>* Patients will evaluate their pain levels via a verbal numerical scale on days 1(or-1), 2, 3, 4, 5, 6 & 7.<br>Other: In hospital questionnaires<br>* Patients are required to fill out the HADS and PCS questionnaires between on day -1 or +1.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The pain trajectory for the first 7 post-operative days. | The 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. | Day 7 post-surgery | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The DN4 questionnaire |  | month 3 | 
| Since the surgery, do you have persistent pain? yes/no |  | month 3 | 
| Is it the same pain before the surgery? yes/no |  | month 3 | 
| Verbal numberical scale for pain (ranging from 0 to 10) |  | month 3 | 
| Have you had complications from your surgery? yes/no |  | month 3 | 
| Hospital Anxiety and Depression Scale (HADS) |  | day -1 or day +1 | 
| Pain Catastrophizing Scale (PCS) |  | day -1 or day +1 | 
| Cumulative consumption of antalgic drugs |  | day -1 or day +1 | 
| Cumulative consumption of antalgic drugs |  | day 2 | 
| Cumulative consumption of antalgic drugs |  | day 3 | 
| Cumulative consumption of antalgic drugs |  | day 4 | 
| Cumulative consumption of antalgic drugs |  | day 5 | 
| Cumulative consumption of antalgic drugs |  | day 6 | 
| Cumulative consumption of antalgic drugs |  | day 7 |
