Hospital patients with nosocomial bacteremia and matched hospital control patients without this infection were used to determine the excess hospital costs and mortality attributed to nosocomial bacteremias. Mortality was 14 times greater in patients with nosocomial bacteremia than in matched members of the control group with the same primary diagnoses. An itemized cost analysis, based on 81 case-control pairs, showed an average excess of approximately $3,600 in direct hospital costs for patients who had nosocomial bacteremias. It is estimated that only 24% of the total excess costs to these hospital patients are preventable. Patients with nosocomial bacteremia had an average hospitalization period that was 14 days longer than the average hospital stay for members of the control group.
患有医院获得性菌血症的住院患者以及与之匹配的无此感染的医院对照患者被用于确定医院获得性菌血症所致的额外医院成本和死亡率。医院获得性菌血症患者的死亡率比具有相同原发性诊断的对照组匹配成员高14倍。基于81对病例对照的详细成本分析显示，患有医院获得性菌血症的患者的直接医院成本平均多出约3600美元。据估计，这些住院患者的总额外成本中只有24%是可预防的。医院获得性菌血症患者的平均住院时间比对照组成员的平均住院时间长14天。
