In evaluating a health program using RE-AIM, which dimension assesses long-term viability and integration into practice?

• A. Reach
• B. Adoption
• C. Implementation
• D. Maintenance

Answer: (D)

Maintenance centers on whether a health program becomes a lasting part of routine practice and continues to deliver benefits over time. It looks at long-term viability by considering if outcomes are sustained after initial implementation, and whether the program becomes embedded in organizational systems, policies, and funding so it can continue with minimal external support. By contrast, Reach focuses on who is touched by the program, Adoption on how many settings or providers begin using it, and Implementation on how faithfully and efficiently the program is delivered. So the dimension that captures long-term integration into practice is Maintenance.
