研究目的:

主要目的:明确 PFA 术后严重溶血性肾脏应激事件的累积发生率;验证“BSA 校正的脉冲负荷指数”预测该复合终点的效能,并确立最佳截断值(Cut-off value)。 次要及探索性目的: 构建包含 PFA 导管参数与患者基线特征的多因素临床风险评分模型;评估围术期体重标准化水化率(WAHR)对“脉冲负荷-肾损伤”风险轴的修饰/保护效应。  

Objectives of Study:

Primary Objectives: 1. To determine the cumulative incidence of severe hemolytic kidney stress events following pulsed field ablation (PFA). 2. To validate the predictive performance of the body surface area (BSA)-adjusted pulse load index for this composite endpoint and establish its optimal cut-off value. Secondary and Exploratory Objectives: 1.To develop a multivariable clinical risk prediction model incorporating PFA catheter parameters and patient baseline characteristics. 2.To evaluate the modifying/protective effect of the perioperative weight-adjusted hydration rate (WAHR) on the "pulse load–kidney injury" risk axis.

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:

数据采集: 1. CRF 设计: 本研究将根据研究方案设计标准化的纸质或电子病例报告表(Case Report Form, CRF)。CRF 涵盖人口学特征(身高、体重、性别、年龄)、PFA 手术参数(导管构型、脉冲计数、接触情况)、术中血流动力学记录(低血压负荷)、围术期关键实验室指标(fHb, LDH, Cystatin C, SCr 等)及围术期液体管理量。 2. 源数据采集: 由经过统一培训的护士或医师负责数据采集。源数据主要来源于医院信息系统(HIS)、实验室信息系统、医学影像系统及 PFA手术记录。 数据管理: 1. 数据库构建: 本研究将建立专用的电子数据库。数据库结构将设置逻辑查错程序(Range Check),以限制异常值(如血压 < 0 或 > 300)的录入,确保数据逻辑的一致性。 2. 数据标准化: 所有实验室指标统一单位标准;连续变量(如时间、剂量)录入精确数值,分类变量进行标准化编码(Coding)。 3. 数据录入与核查 (1) 录入机制: 实行 “双人独立录入与核对”或“单人录入+第二人全量核查”制度。数据录入员在 CRF 填写完成后 1 周内将数据录入电子数据库。 (2)数据清洗: 每月进行一次数据核查。针对缺失值(Missing Data)、离群值(Outliers)或逻辑错误(Logical Errors),数据管理员将向主要研究者发出数据疑问表,由研究者核查源文件后予以更正或确认。 4 数据存储与安全 (1) 隐私保护: 遵循《个人信息保护法》,数据库中不得出现受试者姓名、身份证号等直接识别信息,所有受试者均通过病案号进行识别。 (2)存储介质: 电子数据库存储于医院内网指定的专用科研电脑中,设置强密码访问权限(仅限主要研究者及指定统计人员访问)。 (3)备份机制: 每周进行一次数据备份,备份文件加密后存储于独立的离线移动硬盘中,由专人保管,防止数据丢失或被篡改。

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

Data Collection: 1. CRF Design: This study will design standardized paper or electronic Case Report Forms (CRFs) according to the study protocol. The CRFs will cover demographic characteristics (height, weight, sex, age), PFA procedure parameters (catheter configuration, pulse count, contact status), intraoperative hemodynamic recordings (hypotension burden), perioperative key laboratory indicators (fHb, LDH, Cystatin C, SCr, etc.), and perioperative fluid management volume. 2. Source Data Collection: Data collection will be performed by uniformly trained nurses or physicians. Source data will be mainly derived from the Hospital Information System (HIS), Laboratory Information System, Medical Imaging System, and PFA procedure records. Data Management: 1. Database Construction: A dedicated electronic database will be established for this study. The database structure will include a logical error checking routine (Range Check) to restrict entry of abnormal values (e.g., blood pressure < 0 or > 300), ensuring logical consistency of the data. 2. Data Standardization: All laboratory indicators will be standardized to uniform units; continuous variables (e.g., time, dose) will be entered as precise values, and categorical variables will be standardized using coding. 3. Data Entry and Verification: (1) Entry Mechanism: A "dual independent entry and cross-check" or "single entry plus full verification by a second person" system will be implemented. Data entry personnel will enter the data into the electronic database within one week after the CRF is completed. (2) Data Cleaning: Data verification will be performed monthly. For missing data, outliers, or logical errors, the data administrator will issue a data query form to the principal investigator, who will verify the source documents and make corrections or confirmations accordingly. 4. Data Storage and Security: (1) Privacy Protection: In compliance with the Personal Information Protection Law, no directly identifiable information (e.g., patient names, ID numbers) will appear in the database. All subjects will be identified solely by their medical record numbers. (2) Storage Medium: The electronic database will be stored on a designated research computer within the hospital’s intranet, with strong password-protected access restricted to the principal investigator and designated statistical personnel only. (3) Backup Mechanism: A weekly data backup will be performed. Backup files, encrypted, will be stored on a separate offline external hard drive, kept by a designated person to prevent data loss or tampering.
