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:

数据采集包括患者年龄、性别、基础疾病、症状和体征,检查结果(CTPA、D二聚体、肌钙蛋白、BNP/NT-proBNP )等数据。对所有患者进行为期3个月随访,记录患者的住院时间、并发症发生情况、30天内死亡率以及3个月内的总死亡率等预后指标。将上述指标详细填写于病例记录表。通过ResMan平台对数据进行电子采集和管理。

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

Data collection will encompass patient age, gender, underlying diseases, symptoms and signs, as well as test results (CTPA, D-dimer, troponin, BNP/NT-proBNP, etc.). All patients will undergo a 3-month follow-up to document prognostic indicators such as hospital stay duration, occurrence of complications, 30-day mortality rate, and total mortality rate within 3 months. These indicators will be meticulously recorded on the case report form. Data will be electronically collected and managed via the ResMan platform.
