National estimations of airway foreign bodies in children in the United States, 2000 to 2009

Abstract

Objective

Identify risk factors associated with airway foreign bodies in children in the United States and report observed trends over time.

Data source

KID database (2000‐2009).

Methods

ICD‐9‐CM codes for airway foreign bodies were used to identify patients. Risk factors were used for univariate analysis and a multivariate model to identify any increased risk of mortality. These factors were then also trended over time.

Results

Children with airway foreign bodies demonstrate similar risk factors as previously reported, such as male gender, age less than five years old, and lack of private insurance. The weighted mortality rate for pediatric inpatients with airway foreign bodies was about 2.75%. Fortunately, the rate remained relatively unchanged from 2000 to 2009. Geographically, urban hospital settings appeared to be more affected. Increased risks of mortality were noted for older age, urban hospital setting, and teaching hospital status.

Conclusions

Our findings confirm previous findings and identified that the diagnosis of airway foreign bodies in children were associated with male gender, age less than five years old, lack of private insurance, and geographic location in an urban setting. Further investigation may be warranted to provide clarity on other factors found to have increased association with mortality for quality improvement.
