Non-hospitalized Traumatic Brain Injury (TBI): Michigan Incidence, Impact and Cost

Funding Source: Centers for Disease Control and Prevention

Project Period: October 1, 2003 - September 30, 2007

Project Coordinator: Cheribeth Tan-Schriner, PhD

CDMTR-MPHI in collaboration with the University of Michigan conducted this research project funded by CDC which aimed to 1) determine the incidence and characteristics of non-hospitalized mild traumatic brain injury (MTBI) patients; 2) determine the outcomes associated with non-hospitalized MTBI, in particular post concussive syndrome (PCS); 3) evaluate the level of agreement between case identification of non-hospitalized MTBI using surveillance ICD-9-CM criteria versus case identification protocols in the emergency department (ED) cohort study, and determine the costs & services associated with non-hospitalized MTBI.

Two broad study designs were used:

1) analysis of secondary data using Michigan emergency department (ED) data and Medicaid and private insurers data systems;

2) a cohort study of a sample of adults treated at an ED for TBI and subsequently discharged home from the ED who were surveyed four times within a period of one year after their injury event. Self-reported survey measures included: demographic information, health status, PCS and cognitive symptoms, health service utilization and needs, adaptive functioning, community integration and an alcohol-related assessment. Study findings have been disseminated at several national and local conferences. Academic articles have also been submitted to peer-reviewed journals for publication.
