Lower retention rate for Hispanics indicates need for targeted retention strategies for longitudinal rehabilitation research in traumatic brain injury
East Hanover, NJ – August 22, 2018 –Researchers analyzed data from the Traumatic Brain Injury Model System National Data and Statistical Center (TBIMSDSC) to study the contribution of race and ethnicity to retention of participants in TBI research. Their article: Sander A, (doi: 10.1097/HTR.0000000000000395) was published ahead of print by the Journal of Head Trauma Rehabilitation on July 1., Ketchum JM, Hammond FM, Williams Gary K, Pappadis MR, ER Felix, D Johnson-Greene, T Bushnik:
A national team of investigators looked at TBIMS data for 7685 individuals who self-identified as white, black, or Hispanic. Among this group of 5548 whites, 1347 blacks and 790 Hispanics, researchers found that the retention rate at one to two years post-injury for Hispanics (85.2%) was lower than the rates for blacks (90.5%) or whites (98.5%). Other variables adversely affecting retention included substance abuse, age, lower education level, violent cause of injury, and discharge to an institution vs a private residence.
“These findings illustrate the pitfalls associated with grouping different minorities when looking at retention rates in TBI research,” noted co-authorco-investigator with the . “The validity of our research depends upon the participation of individuals of all races and ethnicities,” he said. “Clearly, race/ethnicity is important to consider when developing strategies for retaining participants in our longitudinal rehabilitation research. We need to develop retention strategies that engage Hispanic individuals, and continue to monitor their ongoing participation.”
The scientists acknowledged the need for prospective studies, and the importance of addressing the impact of the spectrum of environmental and socio-economic factors and their complex interactions with race and ethnicity.

About the TBI Model System
The Traumatic Brain Injury Model Systems (TBIMS) program, sponsored by the, Administration for Community Living, U.S. Department of Health and Human Services, supports innovative projects and research in the delivery, demonstration, and evaluation of medical, rehabilitation, vocational, and other services designed to meet the needs of individuals with traumatic brain injury. NIDILRR awards TBI Model Systems grants to institutions that are national leaders in medical research and patient care; these institutions provide the highest level of comprehensive specialty services from the point of injury through eventual re-entry into full community life. The current grant cycle supports 15 regional TBI Model Systems across the U.S. Each TBI Model System contributes to the , participates in independent and collaborative research, and provides information and resources to individuals with TBI; their families, caregivers, and friends; health care professionals; and the general public. Nancy Chiaravalloti, PhD, is the project director of the Northern New Jersey TBI Model System at Kessler Foundation.
