研究三级管理体系对住院手术儿童感染的预防效果。

选取2013年1月至2014年12月于本院进行手术的2 000例住院儿童为研究对象，其中2013年1～12月收治的1 000例儿童为对照组，2014年1～12月收治的1 000例儿童为观察组。对照组患儿采用常规管理体系，观察组则采用三级管理体系，比较两组医护人员感染知识知晓度、预防态度合格率以及两组住院手术儿童院内感染率，并对感染多重耐药菌进行分析。

观察组医护人员感染知识知晓度为84.55%，预防态度合格率为90.00%，均显著高于对照组，差异具有统计学意义（χ² = 8.561、11.269，P = 0.019、0.008）；观察组患儿院内感染率为5.40%，显著低于对照组（14.60%）（χ² = 6.148、P = 0.026）；共分离出124株病原菌，其中68株凝固酶阴性葡萄球菌构成比最高（占54.84%），其次是链球菌和气球菌等。

三级管理体系可以有效预防住院手术儿童发生院内感染，提高医护人员的感染知识知晓度和预防态度合格率。

To investigate the effects of three-grade management system on preventing the children with infection after ambulatory surgery.

Total of 2 000 hospitalized children with surgery from January 2013 to December 2014 in our hospital were selected. Among whom, 1 000 cases collected from January to December 2013 were collected as the control group, given conventional management system; while 1 000 cases collected from January to December 2014 were collected as the observation group, given three-grade management system. The rates of health care workers’ infection knowledge, prevention attitudes and hospitalized surgical children’s infection rates of two groups were compared, respectively and the multi-drug resistant infections were analyzed.

The rates of health care workers’ infection knowledge and prevention attitudes of the observation group were 84.55% and 90.00%, respectively, significantly higher than those of the control group (χ² = 8.561, 11.269; P = 0.019, 0.008). The infection rate of patients in observation group was 5.40%, significantly lower than that (14.60%) of the control group (χ² = 6.148, P = 0.026). Total of 124 pathogens were isolated, including 68 strains of MRCNS, as the highest ratio of 54.84%, followed by Streptococcus and Balloons.

Three-grade management system coule be effective in preventing the infection of hospital inpatient after surgery, and improving the rates of health care workers’ infection prevention attitudes and knowledge about infection.
