Does Co-Occurring Traumatic Brain Injury Affect VHA Outpatient Health Service Utilization and Associated Costs Among Veterans With Posttraumatic Stress Disorder? An Examination Based on VHA Administrative Data.J Head Trauma Rehabil. 2017 Jan/Feb; 32(1):E16-E23.JH
OBJECTIVE
To examine whether a traumatic brain injury (TBI) diagnosis was associated with increased outpatient service utilization and associated costs among Iraq and Afghanistan (Operation Enduring Freedom [OEF]/Operation Iraqi Freedom [OIF]/Operation New Dawn [OND]) War veterans with posttraumatic stress disorder (PTSD) who used Veterans Health Affairs (VHA) care in a 1-year period.
SETTING
N/A.
PARTICIPANTS
OEF/OIF/OND veterans with a diagnosis of PTSD and/or TBI who utilized VHA services during fiscal year 2012 (N = 164 644).
DESIGN
Observational study using VHA administrative data.
MAIN MEASURES
Outpatient VHA utilization (total and by category of care) and associated costs (total and by VA Health Economic Resource Center cost category).
RESULTS
Veterans in the comorbid PTSD/TBI group had significantly more total outpatient appointment than veterans with PTSD but no TBI. This pattern held for all categories of care except orthopedics. The comorbid TBI/PTSD group ($5769) incurred greater median outpatient healthcare costs than the PTSD ($3168) or TBI-alone ($2815) group.
CONCLUSIONS
Co-occurring TBI increases the already high level of healthcare utilization by veterans with PTSD, suggesting that OEF/OIF/OND veterans with comorbid PTSD/TBI have complex and wide-ranging healthcare needs.
