Abstract: Objective To explore effect of quality control circle (QCC) activity in the screening of nutritional risks in hospitalized children. Methods Based on QCC procedure, we established the activity theme as "improving the screening rate of nutrition risk in hospitalized children". Targeted questions were designed for multiple divisions to carry out surveys, including Division of General Surgery, Division of Gastroenterology, Division of Rheumatology Immunology and Division of Neurology. The factors were analyzed and discussed in detail concerning why nutritional risk screening was not performed for hospitalized children. Subsequently, the rate of conducting nutritional risk screening before and after QCC was compared in the above mentioned four divisions. Results In view of the improvement focus, through the implementation of QCC protocol, the improvement rate of Pareto comparing before with after the activity was 88.83%, and the goal achievement rate was 93.35%. The rate of nutritional risk screening in hospitalized children was significantly improved. The screening rate after the activity was 84.4%(1 207/1 430), higher than that before the activity(40.5%，530/1 309), and the difference was statistically significant(P<0.05). Intangible results showed positive growth, the circle members were more skilled in the use of quality control techniques, and team cohesion was also significantly improved. Conclusion QCC can effectively increase the rate of nutritional risk screening in hospitalized children. The PDCA based QCC protocol can effectively improve the screening rate of nutrition risk in hospitalized children, thus solve the clinical practical problems. While improving the rate of nutritional risk screening in hospitalized children, nutritional intervention and nutrition management should be provided for children with nutritional risks, so as to provide evidence for clinical nutritional support.
