背景：出院数据是护理质量的潜在信息来源;但是，在此情况下，他们缺乏详细的临床数据。目的。评估出院数据描述护理模式的有用性。研究设计。队列研究比较出院数据与从病历和患者收集的数据。患者。马萨诸塞州和明尼苏达州诊断为早期乳腺癌的妇女（1993-1995）.测量.原始数据集中与出院数据集中的记录不匹配的患者的百分比，以及出院数据集中与原始数据集中的记录不匹配的患者的百分比。根据患者和医院的特征，在一个数据集中出现而在另一个数据集中不出现的比值比。结果：对于原始数据集中的患者，26.9%来自马萨诸塞州和13.2%来自明尼苏达州的患者与出院数据集中的记录不匹配。在这两个州，与出院数据不匹配的相关因素包括接受保乳手术、住院时间较短和治疗医院。对于出院数据集中的患者，马萨诸塞州有43.4%和明尼苏达州有30.3%与原始数据集中的患者不匹配。在这两个国家，相关因素未能匹配的主要data.Conclusions治疗医院和存在的阳性lymph nodes.Conclusions的。出院数据是相当敏感的，当与早期乳腺癌患者谁被确定通过医院记录。然而，出院数据缺乏特异性。如果出院数据用于表征早期疾病住院患者的护理模式，则估计值可能不准确，因为用于计算手术率的分母中包含了不合适的患者。
Background.Hospital discharge data are a potential source of information for quality of care; however, they lack detailed clinical data.Objectives.To assess the usefulness of hospital discharge data for describing patterns of care.Research Design.Cohort study comparing hospital discharge data with data collected from medical records and patients.Patients.Women diagnosed with early-stage breast cancer in Massachusetts and Minnesota (1993–1995).Measures.The percentage of patients in the primary data set who did not match a record in the discharge data set, and the percentage of patients in the discharge data set who did not match a record in the primary data set. Odds ratios for appearing in one data set, but not the other according to patient and hospital characteristics.Results.For patients in the primary data set, 26.9% from Massachusetts and 13.2% from Minnesota did not match a record in the discharge data set. In both states, factors associated with failure to match to the discharge data included receipt of breast conserving surgery, shorter length of stay, and treatment hospital. For patients in the discharge data set, 43.4% in Massachusetts and 30.3% in Minnesota did not match a patient in the primary data set. In both states, factors associated with failure to match to the primary data included treatment hospital and the presence of positive lymph nodes.Conclusions.Hospital discharge data were fairly sensitive when linked to patients with early-stage breast cancer who were identified through hospital records. The discharge data lacked specificity, however. If discharge data are used to characterize patterns care for inpatients with early stage disease, estimates are likely to be inaccurate due to the inclusion of unsuitable patients in the denominator used to calculate procedure rates.
