Impact of Postoperative Transitional Pain on Recovery After Thoracic Surgery

Study Overview
=================
Brief Summary
-----------------
Postoperative transitional pain corresponds to the pain occuring between acute postoperative pain and chronic postsurgical pain (defined as pain persisting for at least 3 months after surgery). We hypothesized that both trajectory and neuropathic component of transitional pain may influence the quality of recovery after thoracic surgery. To test this, we designed an observational study to identify risk factors for incomplete recovery assessed through the QoR-15 questionnaire.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Consecutive patients scheduled for thoracic surgery<br> | Other: QoR-15 questionnaire<br>* The QoR-15 is a 15-item questionnaire on postoperative quality of recovery. The DN4 is a 10-item questionnaire on neuropathic pain. Both questionnaires will be given to the patients preoperatively, on postoperative days 2 and 3, and 1, 3 and 6 months after surgery.<br>* Other names: DN4 questionnaire;|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Impact of pain trajectory and neuropathic component of pain on quality of recovery. | An incomplete recovery will be defined as a postoperative QoR-15 score of at least 8 points lower than the preoperative QoR-15 value. The association between both trajectory and neuropathic component of postoperative transitional pain and incomplete recovery will be evaluated. | 3 months after surgery. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Description of trajectory and neuropathic component of postoperative transitional pain. | To describe the trajectory and neuropathic component of postoperative transitional pain according to QoR-15 and DN4 successive values. | Between postoperative day 2 and 3 months after surgery. | 
| Impact of the type of surgery on quality of recovery. | To assess the impact of thoracotomy or video-assisted thoracic on quality of recovery. | 3 months after surgery. | 
| Impact of pain trajectory, neuropathic component of pain and type of surgery on chronic postsurgical pain prevalence. | To assess the impact pain trajectory, neuropathic component of pain and type of surgery on chronic postsurgical pain prevalence. | 3 and 6 months after surgery. | 
| Predictive accuracy of neuropathic pain trajectory on incomplete recovery and chronic postsurgical pain prevalence. | To assess the predictive accuracy of neuropathic pain trajectory on incomplete recovery and chronic postsurgical pain prevalence. | 3 and 6 months after surgery. | 
| Correlation between neuropathic componente of chronic postsurgical pain and quality of recovery. | To assess the correlation between neuropathic componente of chronic postsurgical pain and quality of recovery. | 3 and 6 months after surgery. |
