Injury Region and Risk of Hospital-Acquired Pneumonia Among Pediatric Trauma Patients

Abstract

OBJECTIVE: To describe the relationship between injury region and risk of hospital-acquired pneumonia (HAP) in pediatric trauma patients. METHODS: Analyses included patients <19 years of age from the National Trauma Data Bank, during 2009–2011. Multivariable logistic regression was used to examine the association between injury region and odds of developing HAP stratified by age group. RESULTS: A total of 71 377 patients were eligible for analysis, and 1818 patients developed pneumonia. In adjusted regression models both younger (11–15 years) and older (16–18 years) adolescents with multisite injuries including the head and neck had higher odds of developing HAP compared with adolescents with isolated head and neck injuries (odds ratio [OR] = 2.04, 95% confidence interval [CI] 1.34–3.10; OR = 1.47, 95% CI 1.14–1.89, respectively), and younger adolescents with multisite injuries not involving the head and neck also had higher odds of developing HAP (OR = 1.97, 95% CI 1.08–3.60). We found no significant association between injury region and risk of HAP in children <11 years of age. Younger and older adolescents with firearm (OR = 1.85, 95% CI 1.00–3.42; OR = 1.39, 95% CI 1.02–1.88, respectively) or pulmonary (OR = 3.78, 95% CI 1.26–11.3; OR = 2.56, 95% CI 1.01–6.51, respectively) injuries had higher odds of developing HAP compared with those with motor vehicle collision injuries. CONCLUSIONS: Adolescent trauma patients with multisite injuries including the head and neck have a higher risk of developing HAP compared with those with isolated head and neck injuries. We identified several risk factors that can be used to inform future research focused on identifying subgroups at high risk for the development of HAP.
