Epidemiological studies often rely on self-reported cardiovascular disease (CVD) information, but this may be inaccurate. We investigated the accuracy of self-reported CVD (myocardial infarction, stroke, coronary artery bypass surgery and coronary artery angioplasty) during the follow up of the Australian Diabetes, Obesity and Lifestyle (AusDiab) study. Self-reported CVD events, including the date of the event and hospital admission details, were collected with an interviewer-administered questionnaire. Of the 276 self-reported CVD events, 188 (68.1%) were verified by adjudication of medical records. Furthermore, linkage to the statewide Western Australian Hospital Morbidity Database (WAHMD) showed that CVD events were unlikely to be missed, with only 0.2% of those denying any CVD event being recorded as having had an event on the WAHMD. The adjudication of medical records was as accurate as record linkage to the WAHMD for validation of self-reported CVD, but combining the results from both methods of ascertainment improved CVD event identification.
流行病学研究常常依赖自我报告的心血管疾病（CVD）信息，但这可能不准确。我们在澳大利亚糖尿病、肥胖与生活方式（AusDiab）研究的随访期间，调查了自我报告的CVD（心肌梗死、中风、冠状动脉搭桥手术和冠状动脉血管成形术）的准确性。通过访谈式问卷收集自我报告的CVD事件，包括事件发生日期和住院详情。在276例自我报告的CVD事件中，188例（68.1%）经医疗记录判定得到证实。此外，与西澳大利亚州全州医院发病率数据库（WAHMD）的关联显示，CVD事件不太可能被遗漏，在WAHMD中，否认有任何CVD事件的人中只有0.2%被记录为发生过事件。对于自我报告的CVD验证，医疗记录判定与与WAHMD的记录关联一样准确，但将两种确定方法的结果结合起来可改善CVD事件识别。
