Nosocomial infection is an important contributor to morbidity and mortality in pediatric solid organ transplantation. The relative effect of protective gown and glove isolation was compared with strict handwashing in pediatric intensive care unit (PICU) patients with solid organ transplantation.
DESIGN/SETTING: A prospective, randomized design was used; children in a 23-bed PICU with solid organ transplantation were enrolled into a gown and glove protective isolation protocol or a strict handwashing protocol.
All children admitted to the PICU immediately after solid organ transplantation, excluding renal transplantation, and at subsequent readmissions to the PICU were eligible for the study. Children with current infection or known exposure to varicella were excluded from the study initially or at readmission.
By using a block randomization design based on organ transplanted, age, and initial admission vs. readmission, each patient was randomized to either strict handwashing or protective gown and glove isolation intervention groups.
We analyzed demographics, infection outcomes (defined according to Centers for Disease Control criteria), and monitoring of patient contacts in compliance with protocols.
The infection rate in the overall PICU population did not change significantly from the year before the study compared with during the study (2.1 per 100 vs. 1.95 per 100 patient days; p =.4) The infection rate in the gown and glove group (2.3 per 100 patient days) was reduced significantly compared with the prestudy infection rate in the transplant population (4.9 per 100 patient days; p =.0008). Strict handwashing also significantly reduced the infection rate in the transplant population (3.0 per 100 patient days; p =.008). Compliance with gowning and gloving was 82% and compliance with handwashing was 76% (compared with 22% before study [p <.0001] and 52% after the study [p <.0001]). Despite an increased mean length of stay in the PICU in the gown and glove group (p =.014), there was a trend toward reduction in the incidence of infection (Fisher's exact test, p =.07; odds ratio,.76) in the gown and glove group.
Increased compliance with handwashing was associated with a reduction in nosocomial infections, and gown and glove isolation appeared to have an additional protective effect. Some nosocomial infections may be preventable in the pediatric solid organ transplantation population.
医院感染是小儿实体器官移植中发病和死亡的重要原因。比较了防护服和手套隔离与严格洗手对小儿实体器官移植重症监护病房(PICU)患者的相对效果。
设计/场所:采用前瞻性随机设计;将拥有23张床位的PICU中接受实体器官移植的儿童纳入防护服和手套防护隔离方案或严格洗手方案。
所有在实体器官移植后立即入住PICU(肾移植除外)以及随后再次入住PICU的儿童均符合研究条件。目前有感染或已知接触水痘的儿童在初次入院或再次入院时被排除在研究之外。
采用基于移植器官、年龄以及初次入院与再次入院的区组随机设计,将每位患者随机分为严格洗手组或防护服和手套隔离干预组。
我们分析了人口统计学数据、感染结局(根据疾病控制中心标准定义)以及对符合方案的患者接触情况进行监测。
与研究前一年相比,研究期间整个PICU人群的感染率无显著变化(每100个患者日分别为2.1例和1.95例;p = 0.4)。防护服和手套组的感染率(每100个患者日2.3例)与移植人群研究前的感染率(每100个患者日4.9例;p = 0.0008)相比显著降低。严格洗手也显著降低了移植人群的感染率(每100个患者日3.0例;p = 0.008)。穿防护服和戴手套的依从率为82%,洗手依从率为76%(与研究前的22%[p < 0.0001]和研究后的52%[p < 0.0001]相比)。尽管防护服和手套组在PICU的平均住院时间有所延长(p = 0.014),但该组感染发生率有降低趋势(Fisher精确检验,p = 0.07;优势比为0.76)。
洗手依从性的提高与医院感染的减少相关,防护服和手套隔离似乎具有额外的保护作用。小儿实体器官移植人群中的一些医院感染可能是可预防的。
