The purpose of this study was to examine the outcome implications of implementing a severe sepsis bundle in an emergency department as a quality indicator set with feedback to modify physician behavior related to the early management of severe sepsis and septic shock.
Two-year prospective observational cohort.
Academic tertiary care facility.
Patients were 330 patients presenting to the emergency department who met criteria for severe sepsis or septic shock.
Five quality indicators comprised the bundle for severe sepsis management in the emergency department: a) initiate central venous pressure (CVP)/central venous oxygen saturation (Scvo2) monitoring within 2 hrs; b) give broad-spectrum antibiotics within 4 hrs; c) complete early goal-directed therapy at 6 hrs; d) give corticosteroid if the patient is on vasopressor or if adrenal insufficiency is suspected; and e) monitor for lactate clearance.
Patients had a mean age of 63.8 +/- 18.5 yrs, Acute Physiology and Chronic Health Evaluation II score 29.6 +/- 10.6, emergency department length of stay 8.5 +/- 4.4 hrs, hospital length of stay 11.3 +/- 12.9 days, and in-hospital mortality 35.2%. Bundle compliance increased from zero to 51.2% at the end of the study period. During the emergency department stay, patients with the bundle completed received more CVP/Scvo2 monitoring (100.0 vs. 64.8%, p < .01), more antibiotics (100.0 vs. 89.7%, p = .04), and more corticosteroid (29.9 vs. 16.2%, p = .01) compared with patients with the bundle not completed. In a multivariate regression analysis including the five quality indicators, completion of early goal-directed therapy was significantly associated with decreased mortality (odds ratio, 0.36; 95% confidence interval, 0.17-0.79; p = .01). In-hospital mortality was less in patients with the bundle completed compared with patients with the bundle not completed (20.8 vs. 39.5%, p < .01).
Implementation of a severe sepsis bundle using a quality improvement feedback to modify physician behavior in the emergency department setting was feasible and was associated with decreased in-hospital mortality.
本研究旨在探讨在急诊科实施严重脓毒症集束化治疗作为一种质量指标集,并通过反馈来改变医生与严重脓毒症和脓毒性休克早期管理相关行为的结果影响。
为期两年的前瞻性观察队列研究。
学术性三级医疗设施。
330例就诊于急诊科且符合严重脓毒症或脓毒性休克标准的患者。
五项质量指标构成了急诊科严重脓毒症管理的集束化治疗:a)在2小时内开始中心静脉压(CVP)/中心静脉血氧饱和度(Scvo2)监测;b)在4小时内给予广谱抗生素;c)在6小时内完成早期目标导向治疗;d)如果患者使用血管活性药物或怀疑有肾上腺功能不全,则给予皮质类固醇;e)监测乳酸清除率。
患者的平均年龄为63.8±18.5岁,急性生理与慢性健康状况评分系统II评分为29.6±10.6,急诊科住院时间为8.5±4.4小时,住院时间为11.3±12.9天,住院死亡率为35.2%。在研究期结束时,集束化治疗的依从性从零增加到51.2%。在急诊科住院期间,与未完成集束化治疗的患者相比,完成集束化治疗的患者接受了更多的CVP/Scvo2监测(100.0%对64.8%,p<.01)、更多的抗生素(100.0%对89.7%,p=.04)和更多的皮质类固醇(29.9%对16.2%,p=.01)。在一项包括五项质量指标的多变量回归分析中,早期目标导向治疗的完成与死亡率降低显著相关(比值比,0.36;95%置信区间为0.17 - 0.79;p=.01)。与未完成集束化治疗的患者相比,完成集束化治疗的患者住院死亡率更低(20.8%对39.5%,p<.01)。
在急诊科环境中,通过质量改进反馈来实施严重脓毒症集束化治疗以改变医生行为是可行的,且与住院死亡率降低相关。
