Emergency Department Discharges for TBI Occurrences by Diagnosis
NOTE: The total numbers here are slightly higher than the total count of patients
because some patients had more than one type of head injury. These data have been
de-duplicated as much as possible.

Total ED discharges of total TBI diagnoses are different than Inpatient discharges. Head
injuries, unspecified are the largest category. This may be due to insufficient detail in the
medical record resulting in a large number of diagnoses being coded in the unspecified
category. Again, the annual numbers for other skull fractures and abusive head trauma
are too small to generate statistically significant information.
