Few studies have described preventive strategies for central line-associated bloodstream infections (CLABSIs) in pediatric hematopoietic stem cell transplantation (HSCT) recipients.
We performed a pilot intervention study in our pediatric HSCT population in 2006-2008 and compared CLABSI rates before and after implementation of preventive strategies (ie, training staff and caregivers in procedures for dressing changes and drawing blood) in the inpatient, outpatient, and non-health care (ie, home) settings. We also studied the pathogens associated with hospital-onset versus community-onset CLABSIs.
During the study period, 90 children (median age, 10 years) underwent HSCT. Fifty-nine children (66%) developed a CLABSI; 18 in the hospital, 27 in the community, and 14 in both settings. After implementation of central line (CL) maintenance care strategies, the overall CLABSI rate declined from 10.03 to 3.00 CLABSIs per 1,000 CL-days (rate ratio, 0.3; 95% confidence interval, 0.2-0.5, P < .0001) and rates declined for both hospital- and community-onset CLABSIs. Gram negative pathogens caused more community-onset (45/65, 69%) than hospital-onset (22/46, 48%) CLABSIs (odds ratio, 2.5; 95% confidence interval, 1.1-5.4; P = .02).
Standardization of care practices for CL maintenance was associated with a reduction of CLABSIs in our pediatric HSCT population. A multicenter study is needed to confirm these observations.
鲜有研究描述过儿童造血干细胞移植(HSCT)受者中与中心静脉置管相关的血流感染(CLABSI)的预防策略。
我们在 2006-2008 年对我院的儿科 HSCT 人群进行了一项试点干预研究,并比较了在住院、门诊和非医疗(即家庭)环境中实施预防策略(即培训医护人员和护理人员进行换衣和采血操作)前后的 CLABSI 发生率。我们还研究了与医院获得性和社区获得性 CLABSI 相关的病原体。
在研究期间,90 名儿童(中位年龄,10 岁)接受了 HSCT。59 名儿童(66%)发生了 CLABSI;18 例发生在医院,27 例发生在社区,14 例同时发生在医院和社区。在实施中心静脉置管(CL)维护护理策略后,整体 CLABSI 发生率从每 1000 CL 天 10.03 例降至 3.00 例(发生率比,0.3;95%置信区间,0.2-0.5,P<.0001),且医院获得性和社区获得性 CLABSI 发生率均下降。革兰氏阴性病原体引起的社区获得性 CLABSI(65/45,69%)多于医院获得性 CLABSI(46/22,48%)(比值比,2.5;95%置信区间,1.1-5.4;P=0.02)。
CL 维护护理实践的标准化与我们儿科 HSCT 人群中 CLABSI 的减少相关。需要进行多中心研究来证实这些观察结果。
