The purpose of this study was to determine if pediatric specialty pediatric team (SPT) interfacility-transported children from community emergency departments to a pediatric intensive care unit (PICU) have improved 48-hour mortality.
This is a multicenter, historic cohort analysis of the VPS, LLC PICU clinical database (VPS, LLC, Los Angeles, CA) for all PICU directly admitted pediatric patients ≤ 18 years of age from January 1, 2007, to March 31, 2009. Categoric variables were analyzed by the chi-square and Mann-Whitney tests for non-normally distributed continuous variables. The propensity score was determined by multiple logistic regression analysis. Nearest neighbor matching developed emergency medical services SPT pairs by similar propensity score. Multiple regression analyses of the matched pairs determined the association of SPT with 48-hour PICU mortality. P values < .05 were considered significant.
This study included 3,795 PICU discharges from 12 hospitals. SPT-transported children were more severely ill, younger in age, and more likely to have a respiratory diagnosis (P < .0001). Unadjusted 48-hour PICU mortality was statistically significantly higher for SPT transports (2.04% vs. 0.070%, P = .0028). Multiple regressions adjusted for propensity score, illness severity, and PICU site showed no significant difference in 48-hour PICU mortality.
No significant difference in adjusted 48-hour PICU mortality for children transported by transport team type was discovered.
本研究旨在确定由儿科专科团队(SPT)从社区急诊科转运至儿科重症监护病房(PICU)的儿童,其48小时死亡率是否有所改善。
这是一项对VPS有限责任公司PICU临床数据库(VPS有限责任公司,加利福尼亚州洛杉矶)进行的多中心历史性队列分析,研究对象为2007年1月1日至2009年3月31日期间所有直接入住PICU的18岁及以下儿科患者。分类变量采用卡方检验分析,非正态分布的连续变量采用曼-惠特尼检验分析。通过多元逻辑回归分析确定倾向得分。最近邻匹配根据相似的倾向得分生成急诊医疗服务SPT配对。对匹配后的配对进行多元回归分析,以确定SPT与48小时PICU死亡率之间的关联。P值<0.05被认为具有统计学意义。
本研究纳入了12家医院的3795例PICU出院病例。由SPT转运的儿童病情更严重,年龄更小,且更有可能有呼吸系统诊断(P<0.0001)。未经调整的SPT转运患者48小时PICU死亡率在统计学上显著更高(2.04%对0.070%,P = 0.0028)。对倾向得分、疾病严重程度和PICU地点进行调整的多元回归分析显示,48小时PICU死亡率无显著差异。
未发现不同转运团队类型转运的儿童在调整后的48小时PICU死亡率上存在显著差异。
