To characterize ventilator-associated pneumonia (VAP) in our pediatric intensive care unit (PICU), implement an evidence-based pediatric VAP prevention bundle, and reduce VAP rates.
The setting is a 25-bed PICU in a 475-bed free-standing pediatric academic medical center. VAP was diagnosed according to Centers for Disease Control and National Nosocomial Infections Surveillance System definitions. A pediatric VAP prevention bundle was established and implemented. Baseline VAP rates were compared with implementation and post-bundle-implementation periods.
VAP is significantly associated with increased PICU length of stay, mechanical ventilator days, and mortality rates (length of stay VAP 19.5+/-15.0 vs non-VAP 7.5+/-9.2, P< .001; ventilator days VAP 16.3+/-14.7 vs non-VAP 5.3+/-8.4, P< .001; mortality VAP 19.1% vs non-VAP 7.2%, P= .01). The VAP rate was reduced from 5.6 (baseline) to 0.3 infections per 1000 ventilator days after bundle implementation; P< .0001. Subglottic/tracheal stenosis, trauma, and tracheostomy are significantly associated with VAP.
PICU VAP is associated with increased morbidity and mortality rates. A multidisciplinary improvement team can implement a sustainable pediatric-specific VAP prevention bundle, resulting in VAP rate reduction.
描述我们儿科重症监护病房(PICU)中呼吸机相关性肺炎(VAP)的特征,实施基于证据的儿科VAP预防综合措施,并降低VAP发生率。
研究地点为一家拥有475张床位的独立儿科教学医疗中心内的一间有25张床位的PICU。VAP根据疾病控制中心和国家医院感染监测系统的定义进行诊断。建立并实施了儿科VAP预防综合措施。将VAP的基线发生率与实施综合措施期间及综合措施实施后的发生率进行比较。
VAP与PICU住院时间延长、机械通气天数增加及死亡率显著相关(VAP组住院时间19.5±15.0天,非VAP组7.5±9.2天,P<0.001;VAP组通气天数16.3±14.7天,非VAP组5.3±8.4天,P<0.001;VAP组死亡率19.1%,非VAP组7.2%,P = 0.01)。综合措施实施后,VAP发生率从每1000个机械通气日5.6例(基线)降至0.3例感染;P<0.0001。声门下/气管狭窄、创伤和气管切开与VAP显著相关。
PICU中的VAP与发病率和死亡率增加相关。一个多学科改进团队可以实施一项可持续的针对儿科的VAP预防综合措施,从而降低VAP发生率。
