Abstract Objective To analyze the high risk factors of invasive fungal infection (IFI) in children with pediatric intensive care unit (PICU) and to establish a risk scoring system. Methods The clinical data of 65 hospitalized children with IFI diagnosis in PICU of Children’s Hospital of Hebei Province from January 2015 to June 2020 were analyzed and included in observation group; according to the principle of 1∶1 allocation, 65 cases of non-IFI hospitalized children with similar underlying diseases in the same period and ward were included in control group. The independent risk factors affecting the occurrence of IFI in children with PICU were analyzed and assigned, an IFI risk scoring system was established, and the ROC curve was drawn to verify the effectiveness of the scoring system. Results The length of hospitalization in observation group was longer than that of control group; and the proportion of indwelling gastric tube, indwelling urinary catheter, central venous catheter, mechanical ventilation >3 days, combination of two or more antibacterial drugs, hypoproteinemia, surgery of observation group were higher than those of control group, and the differences were statistically significant (P < 0.05). Hospitalization days (OR = 1.109, 95%CI: 1.048-1.174), central venous catheter (OR= 38.344, 95%CI: 5.354-274.609), combination of two or more antibacterial drugs (OR=6.194, 95%CI: 2.267-16.924) were independent risk factors for IFI in PICU children (P < 0.05). According to the regression coefficients of independent risk factors, the length of stay was 1, the central venous catheter was 36, and the combination of two or more antibacterial drugs was 18, and a scoring system was established. ROC curve showed that area under the curve was 0.875 (95%CI: 0.816-0.934, P < 0.001), the cut-off value was 0.615, corresponding to the critical value of 28, and the sensitivity was 0.754 and specificity was 0.862. Conclusion The scoring system has good excellent efficiency and good specificity, which is of certain significance for PICU in early identification of IFI high-risk children.
