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:

1. 总体框架:CRF + EDC。 (1)病例记录表(CRF):依据研究方案统一设计并培训使用,核心字段包括研究编号、就诊日期与类型(门诊/急诊)、性别、年龄、诊断名称与ICD-10编码、诊断科室、病种分型(牙周脓肿/根尖脓肿/智齿冠周炎等),以及用于暴露赋值所需的最小定位信息(如院区/行政区)。 (2)电子数据采集与管理系统(EDC):院内部署,角色与权限分级,开启审计追踪。内置数据字典与逻辑校验(日期格式、年龄范围、性别取值、诊断—ICD一致性),自动触发**数据疑问(Query)**并记录处理闭环。 2. 数据来源与整合 (1)临床就诊数据:提取上海市口腔医院2016–2025年门/急诊HIS/EHR记录;按诊断名称与ICD-10识别急性口腔炎症病例。 (2)暴露数据:对接同期气象(日均气温、相对湿度)与空气质量(PM?.?、NO? 等)数据,采用1 km×1 km或同等精度的时空栅格进行匹配。 (3)链接方法:以就诊日为索引日,生成与之匹配的对照日(time-stratified,同年同月同星期几);依据院区/行政区与栅格中心点进行空间匹配,构建暴露与滞后矩阵供DLNM分析。 3. 数据清洗与去重 依据预设的“安全周期”判定同一急性发作期间的重复就诊,仅保留首诊记录;对缺失/异常值进行范围检查与极端值核对;保留清洗与更改的日志。 4. 质量控制(QC) 双人核查与抽样复核(≥10%);月度数据质控报告;程序化校验脚本(R/Python)定期运行,包含:缺失率、重复率、分布/离群点、诊断—ICD一致性与时间分层匹配正确性检查。 5. 隐私保护与安全 全流程去标识化,仅保留研究ID;数据静态与传输加密;院内服务器白名单访问与多因素认证;每日增量 + 每周全量备份与异地容灾;按伦理批准的期限保存与销毁。 6. 文档化与版本管理 建立数据字典、CRF版本与分析脚本(DLNM/GAM、条件Logistic)的版本库;记录所有变更与再现性说明;对外仅发布汇总层面结果。

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

1. Overall framework: CRF + EDC. (1) Case Record Form (CRF): standardized fields (study ID, visit date/type, sex, age, diagnosis name and ICD-10 code, department, phenotype: periodontal abscess / periapical abscess / pericoronitis, and minimal location for exposure assignment such as campus/district). Staff are trained before data entry. (2) Electronic Data Capture (EDC): hospital-hosted with role-based access control and audit trails. Built-in data dictionary and logic checks (date formats, age ranges, sex codes, diagnosis–ICD consistency). Automatic queries are raised and resolved within the system. 2. Sources and linkage (1) Clinical data: outpatient/emergency HIS/EHR records from 2016–2025; acute oral inflammatory cases identified by diagnosis names and ICD-10 codes. (2) Exposure data: meteorological (daily mean temperature, relative humidity) and air-quality (PM?.?, NO?, etc.) datasets; matched on a 1 km×1 km (or comparable) spatiotemporal grid. (3)Linkage method: the index day is the visit day; control days are selected using a time-stratified scheme (same year/month/day-of-week). Spatial matching uses hospital campus/district to grid centroids; exposure lag matrices are generated for DLNM. 3. Cleaning and de-duplication Apply the protocol-specified “safe period” to identify repeat visits within the same acute episode and retain only the index/first visit. Perform range checks, outlier review, and keep a full change log. 4. Quality control (QC) Dual review with ≥10% sample re-checks; monthly QC reports; routine script-based checks (R/Python) covering missingness, duplicates, distribution/outliers, diagnosis–ICD consistency, and correctness of time-stratified matching. 5. Privacy and security Full de-identification (research ID only); encryption at rest and in transit; allow-listed access with MFA; daily incremental + weekly full backups and off-site disaster recovery; retention and destruction per ethics approval. 6. Documentation and versioning Maintain the data dictionary and CRF versions, plus analysis code repositories (DLNM/GAM, conditional logistic models); record all changes for reproducibility; only aggregated results are released externally.
