The authors examine the effectiveness of using hospital discharge data in assessing trends and geographic variations in the occurrence of selected chronic diseases. The Chronic Disease Surveillance System, in place from 1987 to 1991, used hospital discharge data, and Cancer Registry data to tract selected chronic diseases. The authors reviewed data on three diseases: breast cancer, cervical cancer, and lung cancer. A computerized algorithm was used to link multiple records representing a single disease occurrence. To estimate disease occurrence rates from hospital discharge data, repeat admissions for the same disease in any given calendar year were discounted. All rates were directly age-adjusted to the 1985 Maine state population. For all three diseases, the rates obtained from hospital discharge data were higher than Cancer Registry rates. Possible causes for the discrepancies and suggestions for improving the utility of hospital discharge data for chronic disease surveillance are discussed.
作者们研究了利用医院出院数据评估特定慢性病发生趋势和地理差异的有效性。1987年至1991年实施的慢性病监测系统使用医院出院数据和癌症登记数据来追踪特定慢性病。作者们审查了三种疾病的数据：乳腺癌、宫颈癌和肺癌。使用一种计算机算法来链接代表单一疾病发生的多个记录。为了从医院出院数据中估计疾病发生率，在任何给定日历年度内同一种疾病的再次入院情况不予计算。所有发病率均直接按年龄调整至1985年缅因州人口。对于所有这三种疾病，从医院出院数据获得的发病率高于癌症登记发病率。文中讨论了差异的可能原因以及提高医院出院数据在慢性病监测中效用的建议。
