BACKGROUND
Hospital length of stay and discharge destination are important outcome measures in evaluating effectiveness and efficiency of health services. Although hospital administrative data are readily used as a data collection source in health services research, no research has assessed this data collection method against other commonly used methods.
OBJECTIVE
Determine if administrative data from electronic patient management programs are an effective data collection method for key hospital outcome measures when compared with alternative hospital data collection methods.
METHOD
Prospective observational study comparing the completeness of data capture and level of agreement between three data collection methods; manual data collection from ward-based sources, administrative data from an electronic patient management program (i.PM), and inpatient medical record review (gold standard) for hospital length of stay and discharge destination.
RESULTS
Manual data collection from ward-based sources captured only 376 (69%) of the 542 inpatient episodes captured from the hospital administrative electronic patient management program. Administrative data from the electronic patient management program had the highest levels of agreement with inpatient medical record review for both length of stay (93.4%) and discharge destination (91%) data.
CONCLUSION
This is the first paper to demonstrate differences between data collection methods for hospital length of stay and discharge destination. Administrative data from an electronic patient management program showed the highest level of completeness of capture and level of agreement with the gold standard of inpatient medical record review for both length of stay and discharge destination, and therefore may be an acceptable data collection method for these measures.
背景
住院时间和出院去向是评估医疗服务有效性和效率的重要结果指标。尽管医院行政数据在医疗服务研究中很容易被用作数据收集来源，但尚无研究将这种数据收集方法与其他常用方法进行比较评估。
目的
确定与其他医院数据收集方法相比，电子患者管理程序中的行政数据是否是一种用于关键医院结果指标的有效数据收集方法。
方法
前瞻性观察性研究，比较三种数据收集方法在数据捕获完整性和一致性水平方面的差异；从病房来源进行手动数据收集、从电子患者管理程序（i.PM）获取行政数据以及对住院时间和出院去向进行住院病历审查（金标准）。
结果
从病房来源进行的手动数据收集仅获取了医院行政电子患者管理程序捕获的542例住院病例中的376例（69%）。电子患者管理程序的行政数据在住院时间（93.4%）和出院去向（91%）数据方面与住院病历审查的一致性水平最高。
结论
这是第一篇展示住院时间和出院去向数据收集方法之间差异的论文。电子患者管理程序的行政数据在住院时间和出院去向方面显示出最高的捕获完整性水平以及与住院病历审查金标准的一致性水平，因此可能是这些指标可接受的数据收集方法。
