研究目的: |
本研究基于北京协和医院围术期患者安全数据库(POPS-PUMCH Database)所收集的临床数据,拟实现下述目的: 1. 构建基于病案静态特征的外科手术患者术后30天再入院风险预测模型(以下简称“静态特征模型”); 2. 构建融合病案静态特征与术中连续生命体征动态监测数据的多模态预测模型(以下简称“混合神经网络模型”),并量化术中动态监测数据相较于病案静态特征对预测性能的增量贡献; 3. 对上述两套模型进行内部验证,评估其区分度、校准度和可解释性,形成可纳入后续外部验证与系统集成工作的候选模型。 |
||||||||||||||||||||||
|
Objectives of Study: |
Using clinical data already collected within the POPS-PUMCH Database, this study aims to:(1) develop a prediction model for 30-day postoperative readmission in surgical patients based on static medical-record features (the "static-feature model");(2) develop a multi-modal model integrating static medical-record features and continuous intraoperative vital-sign monitoring data (the "hybrid neural network model"), and quantify the incremental predictive value of intraoperative dynamic monitoring over static features;(3) perform validation of both models, evaluating discrimination, calibration, and interpretability, and produce candidate models for subsequent external validation and system integration. |

数据治理:POPS-PUMCH数据库的数据治理流程已运行超过十年,具备成熟的质量控制机制,包括自动化数据导入时的强制逻辑核查、异常值定期监察与溯源核对、结构化数据定期质控抽样复核等。 去标识化:从POPS-PUMCH数据库向研究分析数据集的导出过程中,所有直接识别患者个体的字段(姓名、身份证号、联系方式、家庭住址、住院号等)在导出时即完成去标识化处理。研究分析人员所接触的数据集中仅保留研究编号,不含直接识别信息。去标识化对应关系映射表由数据治理团队单独保存于医院受控信息系统中,与研究分析数据物理隔离,仅在因研究进展确需进行数据核查时,经项目负责人书面申请并经数据治理责任人审核后方可有限度调用。 数据存储与访问控制:研究分析数据集仅存储在处于医院内部网络环境下的专用服务器中,不复制至移动存储设备,不上传至任何公有云服务。访问权限实行基于研究角色的分级授权,每位研究人员使用个人实名账号登录,所有对研究数据集的访问与操作均留有系统日志。 分析过程管理:数据清洗与建模脚本全程留痕,使用版本控制工具管理代码变更。所有统计分析在研究方案锁定后方开始执行。分析结果以最终分析报告与代码仓库形式归档保存。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data governance: the POPS-PUMCH Database has operated under a mature data governance pipeline for more than a decade, with automated logical integrity checks at ingestion, periodic surveillance and source-verification of extreme values, and periodic structured-data quality sampling.De-identification: during extraction from the POPS-PUMCH Database to the research analytic dataset, all directly identifying fields (name, national ID, contact, address, inpatient number) are de-identified at source. Analysts see only a study ID. The re-identification key is kept solely within a hospital-controlled information environment under the custody of the data governance team, physically isolated from the analytic dataset. Access to the key for data verification is granted on a restricted case-by-case basis, subject to written application from the principal investigator and approval by the data governance lead.Data storage and access control: the analytic dataset resides exclusively on a dedicated server within the National Facility of Translational Medicine (PUMCH) — Prevention and Early-Intervention Platform, behind the hospital internal network. No copies are created on removable media and no upload to any public cloud service is permitted. Role-based access authorisation is in force, with personal accounts and full audit trails of all data access and operations.Analytic process management: all data-cleaning and modelling scripts are version-controlled and fully logged. All analyses are performed only after the protocol is locked. Analytic artefacts (final report, code repository) are archived. |
