To test the hypothesis that technology availability, staffing, and diagnostic diversity in an intensive care unit (ICU) are associated with the ability to decrease hospital mortality.
Prospective multicenter descriptive cohort study.
Ten Brazilian medical-surgical ICUs.
1734 consecutive adult ICU admissions.
We recorded the amount of technology, number of diagnoses, and availability of nurses at each ICU. We also used demographic, clinical and physiologic information for an average of 173 admissions to each ICU to calculate standardized mortality ratios (SMRs) for each ICU. The mean SMR for the ten ICUs was 1.67 (range 1.01-2.30). A greater availability of ICU equipment and services was significantly (p < 0.001) associated with a lower SMR.
The ability of Brazilian ICUs to reduce hospital mortality is associated with the amount of technology available in these units.
检验重症监护病房（ICU）中的技术设备可用性、人员配备和诊断多样性与降低医院死亡率的能力相关这一假设。
前瞻性多中心描述性队列研究。
巴西的10个内科-外科ICU。
1734例连续入住成人ICU的患者。
我们记录了每个ICU的技术设备数量、诊断数量和护士配备情况。我们还使用了每个ICU平均173例入院患者的人口统计学、临床和生理学信息来计算每个ICU的标准化死亡率（SMR）。10个ICU的平均SMR为1.67（范围为1.01 - 2.30）。ICU设备和服务的可用性越高，与较低的SMR显著相关（p < 0.001）。
巴西ICU降低医院死亡率的能力与这些科室可用的技术设备数量相关。
