RE-AIM (Reach, Efficacy/Effectiveness, Adoption, Implementation, and Maintenance)

RE-AIM is a conceptual model to help identify key factors to implementation. It is a systematic way for evaluating public health interventions that assesses 5 dimensions: Reach, Efficacy/Effectiveness, Adoption, Implementation, and Maintenance.

Reach is the absolute number, proportion, and representativeness of individuals who participate in a given program.

Efficacy/Effectiveness is the impact of an intervention on important outcomes. This includes potential negative effects, quality of life, and costs.

Adoption is the absolute number, proportion, and representativeness of settings and staff who are willing to offer a program.

Implementation, at the setting level, refers to the how closely staff members follow the program that the developers provide. This includes consistency of delivery as intended and the time and cost of the program.

Maintenance is the extent to which a program or policy becomes part of the routine organizational practices and policies. Within the RE-AIM framework, maintenance also applies at the individual level.

These dimensions occur at multiple levels (e.g., individual, clinic, organization, community) and interact to determine the public health or population based impact of a program or policy.
