Factors associated with the hospital admission of consumer product-related injuries treated in U.S. hospital emergency departments

While unintentional injuries and hazard patterns involving consumer products have been studied extensively in recent years, little attention has focused on the characteristics of those who are hospitalized after treatment in emergency departments, as opposed to those treated and released. This study quantifies the impact of the age and sex of the injury victims, and other factors, on the likelihood of hospitalization. The analysis focuses on consumer product injuries, and was based on approximately 400,000 injury cases reported through the U.S. Consumer Product Safety Commission's National Electronic Injury Surveillance System, a national probability sample of U.S. hospital emergency departments. Logistic regression was used to quantify the factors associated with the likelihood of hospitalization. The analysis suggests a smooth U-shaped relationship between the age of the victim and the likelihood of hospitalization, declining from about 3.4% for children under age 5 years to 1.9% for 15-24 year-olds, but then rising to more than 25% for those ages 75 years and older. The likelihood of hospitalization was also significantly affected by the victim's sex, as well as by the types of products involved, fire involvement, and the size and type of hospital at which the injury was treated. This study shows that the probability of hospitalization is strongly correlated with the characteristics of those who are injured, as well as other factors.
