In the evaluation of a hypertension treatment program, the end-point surveillance included incidence of acute myocardial infarction and acute stroke identified from hospital in-patient registers and the national mortality register. To ascertain the validity, in-patient records containing the ICD-codes 410-411 and 430-438 were validated. First event of acute myocardial infarction and acute stroke suggested in the in-patient register could be confirmed in 96% and 94%, respectively. In-patient diagnoses of suspected acute myocardial infarction or other acute or subacute ischemic heart diseases, transient ischemic attack and unspecified heart diseases, transient ischemic attack and unspecified cerebrovascular disease revealed high proportions of what in fact turned out to be definite events (11%, 24% and 53% respectively). It is concluded that disease ascertainment for this cohort study claims validation of register data with hospital records.
在一项高血压治疗项目的评估中，终点监测包括从医院住院登记册和国家死亡率登记册中确定的急性心肌梗死和急性中风的发病率。为确定有效性，对包含国际疾病分类代码410 - 411和430 - 438的住院记录进行了验证。住院登记册中提示的急性心肌梗死和急性中风的首发事件分别有96%和94%得到了确认。对疑似急性心肌梗死或其他急性或亚急性缺血性心脏病、短暂性脑缺血发作和未特指的心脏病、短暂性脑缺血发作和未特指的脑血管疾病的住院诊断显示，实际上最终确诊为明确事件的比例很高（分别为11%、24%和53%）。得出的结论是，该队列研究的疾病确诊需要用医院记录对登记数据进行验证。
