The assumption that discharge diagnoses of chronic obstructive pulmonary disease and other allied conditions accurately reflect patient medical records was tested using a sample of 553 hospital discharges from the Pittsburgh, Pennsylvania area. Three validation criteria were used in reviewing patient hospital records: 1) the presence of abnormal spirometry test results; 2) reference made to a previous diagnosis of one of the conditions; and 3) reports of respiratory symptoms consistent with these conditions. The findings were that 1 per cent of the 432 cases with a primary diagnosis in this disease category and 10 per cent of the 121 cases with a primary diagnosis of heart disease and a secondary diagnosis in this disease category were not supported by any of the selected criteria.
利用宾夕法尼亚州匹兹堡地区553份医院出院记录样本，对慢性阻塞性肺疾病及其他相关病症的出院诊断能否准确反映患者病历这一假设进行了检验。在审查患者医院记录时采用了三项验证标准：1）存在异常肺功能测试结果；2）提及先前对其中一种病症的诊断；3）报告与这些病症相符的呼吸道症状。研究结果显示，在该疾病类别中以原发性诊断的432例病例中，有1%以及在该疾病类别中以原发性诊断为心脏病且以继发性诊断为该疾病的121例病例中，有10%未得到任何所选标准的支持。
