研究目的:

本项目旨在将数字化鼻牙槽突矫治(DPNAM)技术引入贵州地区,建立适合当地医疗条件的唇腭裂早期干预模式。贵州唇腭裂发病率较高,但传统PNAM技术依赖手工塑形和频繁复诊,难以在基层推广。本项目结合3D打印、AI辅助设计及远程随访,优化矫治流程,降低技术门槛,使更多患儿受益。  

Objectives of Study:

This project aims to introduce the digital nasal-sinus-slab correction (DPNAM) technique to Guizhou region, and establish an early intervention model for cleft lip and palate suitable for local medical conditions. The incidence of cleft lip and palate in Guizhou is relatively high, but the traditional PNAM technique relies on manual shaping and frequent follow-ups, making it difficult to be promoted at the grassroots level. This project combines 3D printing, AI-assisted design, and remote follow-up to optimize the treatment process, reduce the technical threshold, and benefit more children.

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:

一、数据采集工具:定制化的电子病例记录表 1.复诊检查表:用于记录每次随访的关键临床指标。 2.不良事件记录表:用于标准化记录和分级处理治疗过程中的不良事件。 3.基线评估表:记录入组时的牙槽突裂隙宽度、鼻部对称性指数等。 4.其他记录:如知情同意书、随机化信封记录、患者随访依从性记录等。 二、数据管理系统:电子化数据库 + 标准化流程 1.数据录入: 1.方式:双人录入核对,即由两名独立的研究人员分别将纸质CRF数据录入电子数据库,并进行比对,以确保录入的准确性。 2.工具:电子化管理。 3.数据质量控制: 标准化培训:对数据采集者进行统一测量规范的培训,并由3名医师进行校准。 质控抽查:建立质控抽查制度,对 20%的病例进行数据复核(第6页)。 逻辑核查:虽然没有明说,但规范的数据库通常会设置逻辑核查规则(如数值范围检查、必填项检查)。 4.数据存储与安全: 建立网络数据库,方便访问。 安全措施应包括:密码保护、定期备份、权限分级管理(如仅项目负责人和统计人员有修改权限)。

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

I. Data Collection Tools: Customized Electronic Case Record Sheets 1. Follow-up Examination Form: Used to record key clinical indicators for each follow-up visit. 2. Adverse Event Record Form: Used to standardize the recording and grading of adverse events during the treatment process. 3. Baseline Assessment Form: Records the width of the alveolar cleft and the nasal symmetry index at the time of enrollment. 4. Other Records: Such as informed consent forms, randomization envelope records, and patient follow-up compliance records, etc. II. Data Management System: Electronic Database + Standardized Procedures 1. Data Entry: 1. Method: Double-entry verification, that is, two independent researchers separately enter the paper CRF data into the electronic database and compare them to ensure the accuracy of the entry. 2. Tools: Electronic management. 3. Data Quality Control: Standardized training: Provide unified measurement standards training to data collectors and have 3 physicians calibrate. Quality control: Establish a quality control system to review 20% of the cases (page 6). Logical Verification: Although not explicitly stated, standard databases usually set logical verification rules (such as value range checks, mandatory item checks). 4. Data Storage and Security: Establish a network database for convenient access. Security measures should include: password protection, regular backups, and hierarchical permission management (such as only the project leader and statisticians have modification permissions).
