Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Study aims
1. Investigate the incidence of chronic post-surgical pain in Chinese population who received video-assisted thoracic surgery by carrying out a multi-center, perspective cohort study
2. Perform regression analysis to evaluate the risk factors for chronic post-surgical pain in video-assisted thoracoscopic surgery.
3. Establish a risk-prediction model for CPSP after VATS
Time frame:
We plan to recruit patients from Aug 1st, 2022 to Sept 1st, 2022. And our follow-up will be performed at 1 month, 3 months and 6 months after the surgeries. After completing the follow-up of all patients, we are going to build a risk-prediction model and have it validated.
Study subjects Our research focuses on the incidence of CPSP after VATS in Chinese population. To select an accessible population that can well represent the target population, we set geographic criteria as regional medical centers in all seven geographical subregions of China, namely northwestern China, northern China, northeastern China, central China, southern China, southwestern China and southeastern China. Considering the needed sample size and the cost, we set time criteria as one month.
Plan for sampling As described before, our study plans to sample all the patients receiving VATS in participating medical centers across China for one month.
Plan for recruitment All patients receiving VATS in our participating centers will be examined for recruitment by the local coordinators according to our inclusion and exclusion criteria.
Plan for retaining subjects We are going to follow up the patients for at least 6 months after the surgery. At the pre-Op visit, the patient will be informed of the study time frame and he/she will be called by researcher in PUMCH during their follow-up. After their discharge, we will contact the patients and call them at 1, 3, 6 months after surgery.
Patient Registries We will use standard case report form (CRF) and electronic data capture (EDC) system for patient registries. All the data required in this study will be obtained by patient interview and medical records and recorded in our CRF and uploaded into EDC system. Researchers in participating centers will collect patient information by interview during their stay at the hospital. An SOP and interviewer training session will be developed for the study. The EDC system will help with data check, data dictionary. And our data monitoring board in PUMCH will check the uploaded data while follow-up telephoning the patients.
Statistical analysis plan Sample size Expected incidence: 30% Comment: the average reported incidence of CPSP after VATS Desired precision: 10% (total width) Confidence level: 95% Therefore, the estimated sample size with the above-mentioned parameters is 323 The risk factors will be analyzed by Logistics regression.
