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.
