Application of STRONGkids to screen infants with lower respiratory tract infection and its possible influence on clinical outcome

Objective To investigate the incidence of nutritional risk in infants with lower respiratory tract infection, and to compare the effects of different nutritional risks on clinical outcomes, and to provide evidence for clinical nutritional management of infantile lower respiratory tract infection. Methods Infants and young children with lower respiratory tract infection who were hospitalized in our hospital from January 2013 to March 2016 were selected as subjects. Nutritional risk screening was performed using the Nutritional Status and Growth Risk Screening Tool (STRONGkids). Results A total of 957 infants with lower respiratory tract infections were included in the study. The incidence of high nutrition risk and low and medium nutritional risk were 17.6% and 82.4%, respectively. The clinical cure rate was 68.5% and 71.4% respectively. The children with pneumonia and bronchitis had high nutritional risk. The incidence rates were 20.60% and 4.87%, respectively, and the difference was statistically significant (χ2=25.52, P=0.000). Time-effect single factor analysis (Kaplan-Meier method): The hospitalization time for infants with low nutritional risk and high nutritional risk was 9.3(0.3) d and 13.3(1.0) d, respectively. The difference between the two groups was statistically significant. (χ2=28.33, P=0.000), the total hospitalization expenses were 5 653.5(224.8) yuan and 10 079.5(1 755.8) yuan respectively. The difference between the two groups was statistically significant (χ2=4.47, P=0.034). Multivariate COX regression analysis: High nutritional risk was a risk factor for hospitalization of hospitalized infants with lower respiratory tract infection (RR=1.57, P=0.024). Conclusion There is a high incidence of high nutritional risk in infants with lower respiratory tract infection. Compared with children with low and moderate nutritional risk, the hospitalization time is longer, the hospitalization cost is increased, and the clinical cure rate is lower, which is the risk of clinical outcome. factor. Therefore, it is necessary to conduct nutrition risk screening for infants with lower respiratory tract infections, and provide a theoretical basis for clinical nutrition evaluation and nutritional intervention.
