This study examines hospital characteristics that affect the differential in hospital mortality. Death rates for 1984 Medicare inpatients in acute care hospitals, released by the Health Care Financing Administration in 1986, were analyzed. A confirmatory statistical approach to organizational determinants of hospital mortality was formulated and validated through an empirical examination of 239 hospitals. The findings suggest that the effect of hospital size and specialization on mortality was a spurious one when the effects of other variables were simultaneously controlled. A positive association existed between service intensity and hospital mortality: the more hospital services consumed, the higher the mortality rate. Community attributes accounted for more variance in hospital mortality rates than did organizational attributes. The organizational and community factors studied explained 27 percent of the total variance in hospital mortality.
本研究考察了影响医院死亡率差异的医院特征。分析了医疗保健财务管理局于1986年公布的1984年急性护理医院中医疗保险住院患者的死亡率。通过对239家医院的实证检验，制定并验证了一种关于医院死亡率组织决定因素的验证性统计方法。研究结果表明，在同时控制其他变量的影响时，医院规模和专科化对死亡率的影响是虚假的。服务强度与医院死亡率之间存在正相关关系：医院消耗的服务越多，死亡率越高。社区属性在医院死亡率方面比组织属性解释了更多的方差。所研究的组织和社区因素解释了医院死亡率总方差的27%。
