Purpose: The study aimed to understand how use and satisfaction with services following discharge from an acquired brain injury (ABI) acute-care facility related to family caregiver outcomes. Methods: A correlational and descriptive study design was used. Nineteen primary family caregivers of persons recently discharged from an ABI acute-care facility in a large city in the southwestern part of the United States participated. Results: Satisfaction with the services provided during post-acute-care rehabilitation demonstrated medium effect size relationships to family caregiver depression, family dysfunction, and extent of rehabilitation needs met. Service use demonstrated a medium effect size relationship to caregiver family dysfunction. Conclusion: Findings present a call for future research to examine the role of service use and service satisfaction during the continuum of care from acute-care to long-term community integration following ABI.
