The effectiveness of checklists, daily goal assessments, and clinician prompts as quality improvement interventions in intensive care units (ICUs) is uncertain.
To determine whether a multifaceted quality improvement intervention reduces the mortality of critically ill adults.
DESIGN, SETTING, AND PARTICIPANTS: This study had 2 phases. Phase 1 was an observational study to assess baseline data on work climate, care processes, and clinical outcomes, conducted between August 2013 and March 2014 in 118 Brazilian ICUs. Phase 2 was a cluster randomized trial conducted between April and November 2014 with the same ICUs. The first 60 admissions of longer than 48 hours per ICU were enrolled in each phase.
Intensive care units were randomized to a quality improvement intervention, including a daily checklist and goal setting during multidisciplinary rounds with follow-up clinician prompting for 11 care processes, or to routine care.
In-hospital mortality truncated at 60 days (primary outcome) was analyzed using a random-effects logistic regression model, adjusted for patients' severity and the ICU's baseline standardized mortality ratio. Exploratory secondary outcomes included adherence to care processes, safety climate, and clinical events.
A total of 6877 patients (mean age, 59.7 years; 3218 [46.8%] women) were enrolled in the baseline (observational) phase and 6761 (mean age, 59.6 years; 3098 [45.8%] women) in the randomized phase, with 3327 patients enrolled in ICUs (n = 59) assigned to the intervention group and 3434 patients in ICUs (n = 59) assigned to routine care. There was no significant difference in in-hospital mortality between the intervention group and the usual care group, with 1096 deaths (32.9%) and 1196 deaths (34.8%), respectively (odds ratio, 1.02; 95% CI, 0.82-1.26; P = .88). Among 20 prespecified secondary outcomes not adjusted for multiple comparisons, 6 were significantly improved in the intervention group (use of low tidal volumes, avoidance of heavy sedation, use of central venous catheters, use of urinary catheters, perception of team work, and perception of patient safety climate), whereas there were no significant differences between the intervention group and the control group for 14 outcomes (ICU mortality, central line-associated bloodstream infection, ventilator-associated pneumonia, urinary tract infection, mean ventilator-free days, mean ICU length of stay, mean hospital length of stay, bed elevation to ≥30°, venous thromboembolism prophylaxis, diet administration, job satisfaction, stress reduction, perception of management, and perception of working conditions).
Among critically ill patients treated in ICUs in Brazil, implementation of a multifaceted quality improvement intervention with daily checklists, goal setting, and clinician prompting did not reduce in-hospital mortality.

在重症监护病房(ICU)中,检查表、日常目标评估和临床医生提示作为质量改进干预措施的有效性尚不确定。
确定多方面的质量改进干预是否可以降低危重症成年人的死亡率。
设计、地点和参与者:本研究分为 2 个阶段。第 1 阶段是一项观察性研究,评估工作氛围、护理过程和临床结果的基线数据,于 2013 年 8 月至 2014 年 3 月在 118 家巴西 ICU 中进行。第 2 阶段是在 2014 年 4 月至 11 月间与相同的 ICU 进行的一项集群随机试验。每个阶段每个 ICU 均有 60 例超过 48 小时的首诊患者纳入研究。
将 ICU 随机分配到质量改进干预组,包括多学科轮值期间的每日检查表和目标设定,以及 11 项护理流程的临床医生后续提示,或常规护理。
采用随机效应逻辑回归模型分析住院 60 天内(主要结局)的死亡率,调整患者的严重程度和 ICU 的基线标准化死亡率比。探索性次要结局包括护理流程的依从性、安全氛围和临床事件。
共有 6877 例患者(平均年龄,59.7 岁;3218 [46.8%] 例女性)入组基线(观察)阶段,6761 例(平均年龄,59.6 岁;3098 [45.8%] 例女性)入组随机阶段,3327 例患者入组干预组 ICU(n=59),3434 例患者入组常规护理组 ICU(n=59)。干预组和常规护理组的院内死亡率无显著差异,分别为 1096 例(32.9%)和 1196 例(34.8%)(比值比,1.02;95%置信区间,0.82-1.26;P=0.88)。在未经多次比较调整的 20 项预设次要结局中,有 6 项在干预组中得到显著改善(低潮气量使用、避免深度镇静、使用中心静脉导管、使用导尿管、团队合作感知、患者安全氛围感知),而干预组和对照组之间的 14 项结局无显著差异(ICU 死亡率、中心静脉相关血流感染、呼吸机相关性肺炎、尿路感染、无呼吸机天数、ICU 住院时间、医院住院时间、床头抬高至≥30°、静脉血栓栓塞预防、饮食管理、工作满意度、压力减轻、管理层感知和工作条件感知)。
在巴西 ICU 中治疗的危重症患者中,实施多方面的质量改进干预措施,包括每日检查表、目标设定和临床医生提示,并未降低院内死亡率。
