研究目的: |
构建并验证一个基于 XGBoost 机器学习算法的老年慢病共病住院患者跌倒风险预测模型,明确其独立危险因素,并与传统 Logistic 回归模型进行比较,为临床提供高精度、可解释的跌倒风险预警工具,助力跌倒预防管理体系的建立。 |

|
Objectives of Study: |
Develop and validate a fall risk prediction model for elderly patients hospitalized with multiple chronic diseases based on the XGBoost machine learning algorithm, identify its independent risk factors, and compare it with the traditional logistic regression model, providing clinicians with a high-precision, interpretable fall risk warning tool to support the establishment of a fall prevention management system. |

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、采集方式: 系统提取:通过医院电子病历系统(HIS)及老年综合智慧评估系统自动抓取结构化数据。 人工录入:针对非结构化数据(如护理记录中的自由文本),由两名研究人员独立提取并录入《老年慢病共病跌倒危险因素数据提取表》。 采集范围: 覆盖全院老年医学科、综合内科等慢病共病高发科室,纳入筛查阳性的住院患者(通过老年综合评估确定)。 采集流程: 步骤1:制订标准化数据提取表,明确各字段定义及录入规范。 步骤2:由两名课题组研究人员从医院电子病历系统及老年综合智慧评估系统提取数据,包括:基本信息、疾病信息(慢性病种类及数量、共病指数)、用药记录、护理记录、护理措施、环境因素等相关临床信息,确保数据完整性。 步骤3:按跌倒发生情况分组(跌倒组/未跌倒组),标记事件时间(跌倒发生日期)。 步骤4:数据清洗(处理异常值、填补缺失值)、转换(分类变量虚拟化)、标准化(Z-score处理连续变量)。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
I. Data Collection Method:- System Extraction: Structured data is automatically captured through the Hospital Electronic Medical Record System (HIS) and the Comprehensive Geriatric Smart Assessment System.Manual Entry: For unstructured data (e.g., free-text nursing records), two researchers independently extract and enter the data into the "Fall Risk Factor Data Extraction Form for Elderly Patients with Multimorbidity."**II. Collection Scope:**The collection covers departments with high prevalence of multimorbidity, such as Geriatrics and General Internal Medicine, across the hospital. Hospitalized patients who screen positive (identified via comprehensive geriatric assessment) are included.III. Collection Process:Step 1:Develop a standardized data extraction form with clear definitions and entry protocols for each field.- Step 2:Two researchers from the project team extract data from the Hospital Electronic Medical Record System and the Comprehensive Geriatric Smart Assessment System. The data includes: basic information, disease information (types and counts of chronic diseases, multimorbidity index), medication records, nursing records, nursing interventions, environmental factors, and other relevant clinical information to ensure data completeness.- Step 3: Group data based on fall occurrence (fall group/non-fall group) and mark the event time (date of fall occurrence).- Step 4:Perform data cleaning (handling outliers, imputing missing values), transformation (dummy variable creation for categorical variables), and standardization (Z-score normalization for continuous variables).IV. Data Archiving Plan:The data will be archived in the "Zhejiang Provincial Medical Research Database." |
