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. 数据来源:通过衢州市人民医院病历管理系统及康复医学科数据库,提取2022年12月1日至2026年1月31日期间所有主要诊断为急性脑卒中(包括脑梗死、脑出血、蛛网膜下腔出血)的住院患者信息。根据纳入排除标准对提取的病例进行筛选,确定最终纳入的患者。 2. 数据收集:构建统一的表格模板,使用Excel 2021收集并整理数据,对患者隐私数据进行脱敏处理。通过电子病历系统收集纳入患者的人口学与基线特征、检验检查指标、康复治疗明细及其他可能的混杂因素,回溯并确定关键时间节点:(1)时间零点:患者因本次卒中导致连续卧床的第1天;(2)康复启动时间:患者首次接受任何标准化康复治疗(包括物理治疗、低频电刺激、床边蹬车、电动起立床等)的具体日期。(3)观察终点定义为以下任一事件的首发:确诊DVT、死亡、脱离卧床状态,或满90天观察期。 3. 数据管理计划与质量控制:为了确保收集信息的完整性和准确性,本研究实施过程中采取以下措施。 首先在本院内进行了预调查,以此判断本院内就诊的因神经系统疾病导致卧床的患者的数量及所需病历资料完整程度是否满足研究内容,并根据预调查结果及时调整研究方案。 按照修正后的研究设计方案明确信息收集表格,以减少资料收集过程中可能产生的信息偏倚。样本的纳入排除及患者的资料信息收集均由双人背对背开展,有争议的由两人讨论决定,数据收集完毕后,检查是否有遗漏的信息,并对极值和逻辑错误的信息进行核查,查阅原始病历资料进行核对,如遗漏信息无法补充,或极值和逻辑错误无法解释,则该病例予以排除。

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

1. Data Source:Patient information was extracted from the Medical Record Management System of Quzhou People's Hospital and the Rehabilitation Medicine Department Database. All hospitalized patients with a primary diagnosis of acute stroke (including cerebral infarction, intracerebral hemorrhage, and subarachnoid hemorrhage) admitted between December 1, 2022, and January 31, 2026, were identified. Eligible cases were screened according to the inclusion and exclusion criteria to determine the final study population.2.Data Collection:A standardized data collection form was developed, and data were collected and organized using Excel 2021. Patient privacy information was de-identified. Demographic and baseline characteristics, laboratory and examination findings, details of rehabilitation therapy, and other potential confounding factors were collected from the electronic medical record system. Key time points were retrospectively determined as follows:(1) Time zero (T₀): The first day of continuous bed rest due to the current stroke event.(2) Rehabilitation initiation time (T_start): The date of the first standardized rehabilitation therapy (including physical therapy, low-frequency electrical stimulation, bedside ergometry, electric standing bed, etc.).(3) Observation endpoint was defined as the first occurrence of any of the following events: diagnosis of deep vein thrombosis (DVT), death, discontinuation of bed rest, or completion of the 90-day observation period. 3. Data Management Plan and Quality Control:To ensure the completeness and accuracy of the collected information, the following measures were implemented during the study.A pre-investigation was conducted within the hospital to assess the number of patients with bed rest due to neurological disorders and the completeness of the required medical records, ensuring that the study objectives could be met. The study protocol was adjusted accordingly based on the pre-investigation results.A standardized data collection form was established according to the revised study protocol to minimize potential information bias during data collection. Patient screening (inclusion/exclusion) and data collection were performed independently by two researchers. Any discrepancies were resolved through discussion. After data collection was completed, missing information was checked, and extreme values or logical errors were verified against the original medical records. Cases with missing information that could not be supplemented, or with extreme values or logical errors that could not be resolved, were excluded from the study.
