This study validated hypertension (ICD-8: 401.99) in The National Inpatient Register with reference to the use of the diagnosis in the Occupational Hospitalization Register. A university hospital and a regional hospital were chosen for the evaluation. A sample of case records with the discharge diagnosis essential hypertension and additional case records with other diagnoses were re-coded blindly and independently by two doctors. Cause of admission or admission diagnosis was recorded for essential hypertension cases. The agreement with The National Inpatient Register ranged from 60 to 40%. About half of the cases with the discharge diagnosis "essential hypertension" were admitted to hospital due to hypertension, about a quarter due to diagnoses within "other arteriosclerotic diseases" (ICD-8: 400, 402-440). The misclassification may lead to an underestimation of risks of hypertension in various occupations in the Occupational Hospitalization Register or bias the occupational risk pattern of essential hypertension to become more alike that of arteriosclerotic diseases.
本研究参照职业住院登记册中诊断的使用情况，在国家住院登记册中验证了高血压（国际疾病分类第八版：401.99）。选择了一家大学医院和一家地区医院进行评估。两名医生对一组出院诊断为原发性高血压的病例记录样本以及另一组有其他诊断的病例记录进行了盲法独立重新编码。记录了原发性高血压病例的入院原因或入院诊断。与国家住院登记册的一致性在60%至40%之间。约一半出院诊断为“原发性高血压”的病例因高血压入院，约四分之一因“其他动脉硬化性疾病”（国际疾病分类第八版：400、402 - 440）内的诊断入院。这种错误分类可能导致职业住院登记册中对各种职业中高血压风险的低估，或者使原发性高血压的职业风险模式偏向于更类似于动脉硬化性疾病的模式。
