Carrillo, Jorge Alberto | 2015-12-02
Objective. Assess whether the most common imaging findings can predict the hospitalization of a pediatric patient aged 1 month to 5 years.
Materials and method. A prospective type was performed for 1 year in patients with acute lower respiratory tract infection, hospitalized in the Hospital San Jose. Patients were between 1 month and 5 years old, and should have a chest radiograph within 48 hours of admission. Dichotomous variables including the presence or absence of thickening of bronchial walls, consolidation, and atelectasis pleural fluid were used. They were taken as dependent variables of hospital stay, admission to PICU and the requirement for oxygen at home.
59 patients hospitalized during the months of August 2014 to August 2015, the average age was 18.2 months, the population was composed of 30 boys and 29 girls were obtained. Linear regression model was adjusted, finding that consolidation it is the only imagenological alteration statistically significant predictor of hospital stay, presenting the following model.
Hospital Stay = 1.40*consolidation+4.125+ϵ
Where consolidation took values of 1 for presence and 0 for absence of consolidation
Discussion and conclusions.
Hospitalization patient with consolidation had more hospital stay than the patient without consolidation ,
found similar results in the different studies that assessed hospital days compared with findings on chest radiograph.
