Most research on regional differences in hospital stays focuses on systemwide influences, the relative availability of hospital beds, and utilization control mechanisms. In this study, we used a different approach to account for utilization differences between Sacramento, California, and Syracuse, New York: by comparing hospital mean stays at the aggregate level and by diagnosis related groups. We conclude that the shorter mean stays in Sacramento, at both the aggregate and the DRG-specific levels, were produced by a complex variety of factors rather than by systemwide differences in demographics, institutional bed availability, or health maintenance organization penetration. We also found that the largest differences between stays in the two areas were associated with DRGs containing large numbers of elderly, nonsurgical patients.
大多数关于住院时间地区差异的研究都集中在全系统影响、医院床位的相对可获得性以及利用控制机制上。在本研究中，我们采用了一种不同的方法来解释加利福尼亚州萨克拉门托市和纽约州锡拉丘兹市之间的利用差异：通过在总体水平和按诊断相关组比较医院平均住院时间。我们得出结论，萨克拉门托市在总体和特定诊断相关组水平上较短的平均住院时间是由多种复杂因素造成的，而不是人口统计学、机构床位可获得性或健康维护组织渗透率方面的全系统差异。我们还发现，两个地区住院时间的最大差异与包含大量老年非手术患者的诊断相关组有关。
