Objectives:
This study sought to estimate charges associated with USA hospital visits for traumatic brain injury (TBI), compare charges from 2006-2010 and evaluate factors associated with higher charges.
Methods:
The Nationwide Emergency Department Sample database, 2006-2010, was used to estimate charges for emergency department visits and inpatient hospital stays associated with TBI and trends in charges over time were compared. Multivariable linear regression was used to evaluate factors associated with visit charges.
Results:
In 2010, there were $21.4 billion (95% confidence interval (CI) = $17.7-$25.2 billion) in charges for TBI-related admissions, an increase of 22% from 2006. Charges for ED visits resulting in discharge or transfer were $8.2 billion (95% CI = $7.4-$8.9 billion), an increase of 94% from 2006. The proportion of charges for TBI-related visits was disproportionately higher than the proportion of visits for TBI across all years of the study (p < 0.001). Patient age and gender, West region, trauma centre status, non-paediatric hospital designation, metropolitan location and hospital ownership were independently associated with higher charges.
Conclusions:
There was a substantial charge burden from TBI-related hospital visits and charges increased disproportionately to visit volume. There are patient and hospital factors independently associated with higher charges. These findings, as well as methods to reduce the charge burden and charge disparities, deserve further study.
