Nutrition Risk Screening Of Lower Respiratory Tract Infection In Infants And The Effect On Clinical Outcome

Objective: To investigate the nutritional risk of acute lower respiratory tract infection in infants and evaluate the effect of different nutritional risk on clinical outcome?In order to improve the clinical nutrition management level of actute lower respiratory tract infection in infants.Methods: A convenient sample of 957 children who were being treated for lower respiratory tract infection at the First Affiliated Hospital of Fujian Medical University from Jan.2013 to Mar.2016,were included in the analysis.The STROGKids(Screening Tool for Risk of Nutrition in Growth Kids)was applied to every subject for nutritional risk screening.Chi square test,time effect analysis(Kaplan-Meier)and multivariate Cox regression analysis were used for statistical analysis.Results: Of the 957 children with lower respiratory tract infection were enrolled.Based on their STRONGKids scores,77 patients(8.0%)were at low risk of nutritional deterioration on admission,712 cases(74.4%)of the children assessed were categorized as moderate risk,whereas168 patients(17.6%)were at high risk of nutritional deterioration,the cure rates of different levels of nutritional risk were 68.45%,70.93%,75.32%,respectively.185 patients with bronchitis and 772 cases with bronchopneumonitis were included,772 cases of high nutritional risk(4.87%),and the two groups of high nutritional risk rate was statistically significant difference(?2=25.52,P=0.000).The length stay(LOS)of patients at low-moderate nutritional risk was(3.9±0.3)days,and the group at high nutrition risk was(13.3±1.0)days calculated by Kaplan-Meier method of time-effects.With Log-rank significance test method,the difference of Cumulative inpatient percentage was proved to be significant(?2=9.657,P=0.002).Nutrition risk was associated with LOS on Cox multivariate regression analysis model(OR=1.57,95%CI: 1.06?2.32,P=0.024).The low-moderate nutritional risk group and high nutritional risk group costs were(5653.5±1724.21)yuan and(3130.66±1899.8)yuan per patient calculated by Kaplan-Meier method of time-effects,respectively.the difference of Cumulative inpatient percentage was proved to be significant(?2=4.47,P=0.034).In the same way,the average costs per person per day in the two groups were(800.2±63.4)yuan and(735.3±76.1)yuan,respectively.Conclusions: The incidence of high nutritional risk in infants with acute lower respiratory tract infection was high.The high nutritional risk was the risk factors of clinical outcome.And compared with the children with acute low nutritional risk,the LOS,the costs of children with high nutritional was higher and the cure rate was lower.Therefore,it is necessary to carry out nutritional risk screening for children with acute lower respiratory tract infection,and provide theoretical basis for clinical nutrition evaluation,nutritional intervention and treatment of acute lower respiratory tract infection in infants.
