The RE-AIM framework was used to evaluate the implementation experience of 14 organizations in Minnesota over 4 years as they adopted an evidence-based intervention for spousal caregivers. Purpose: To examine the implementation experience and describe sustainability issues. Methods: Mixed-methods using data from qualitative interviews, cost data, and caregiver experience data. Findings: Although the intervention was valued, most organizations were not able to continue providing the program. Conclusion: The results indicate a need for further translation or technical support to identify readiness and prepare the interventionist to offer the program, more robust recruitment methods, and additional funding strategies.
