研究目的:

本项研究旨在评估CO2点阵激光治疗对增生性瘢痕的有效性和安全性,进一步分析CO2点阵激光治疗在不同性别、年龄、部位、瘢痕面积、瘢痕厚度、介入时期、受伤原因和前期治疗之间的疗效差异,为CO2点阵激光治疗对增生性瘢痕治疗提供临床证据,为个体化激光治疗提供循证依据,优化临床干预策略。  

Objectives of Study:

This study aims to assess the efficacy and safety of CO2 fractional laser therapy in the treatment of hypertrophic scars (HS). Furthermore, it seeks to analyze potential differences in therapeutic outcomes based on gender, age, lesion location, scar area, scar thickness, intervention timing, etiology, and prior treatments. The findings are expected to provide clinical evidence supporting the application of CO2 fractional laser therapy for HS, establish an evidence-based foundation for personalized laser treatment protocols, and optimize clinical intervention strategies.

The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url):

Raw data will not be shared in this project, but may be shared privately upon appropriate request with the consent of the principal investigatorand may not be used for commercial purposes. The protocol and metadata will also be shared accordingly.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

根据西南医院住院病例系统获取收集数据并输入到Excel表格中。所有病例记录表格将去除姓名等个人信息,并分配一个唯一的研究编号以保护电者隐私。所有数据记录将上报质控PI保存,用于数据验证。原数据将存储在PI锁定的位置,一直到研究结束和分析完成后至少三年。如果本研究的任何信息和成果在会议或期刊上发表,将不使用受试者姓名和个人信息,我们将组建数据安全监测委员会(DSMB)。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data were collected from the inpatient case system of Southwest Hospital and entered into Excel spreadsheets. All case record forms were anonymized by removing personal identifiers such as names and were assigned unique study identification numbers to protect patient privacy. All data records were submitted to the principal investigator (PI) for quality control and archival purposes to ensure data validation. The original datasets were stored in a PI-secured location for a minimum of three years following study completion and final analysis. Should any research findings be presented at conferences or published in journals, no participant names or personally identifiable information would be disclosed. A Data Safety Monitoring Board (DSMB) was established to oversee data security protocols.
