The current study used four dimensions of the RE-AIM framework (Reach, Adoption, Implementation, and Maintenance) to evaluate the implementation of a statewide abusive head trauma prevention program. Numerous methods, including telephone surveys, paper and pencil questionnaires, site visits, and program administrative data were used to conduct the process evaluation. Results indicate that the intervention was successfully implemented in all birthing hospitals (n=86) across the state with a high degree of fidelity. Furthermore, the majority of the hospitals reported incorporating the program into unit procedures and employee training. More than three-fourths indicated that they plan to continue the program after the study ends. The RE-AIM framework was applied and served as a useful guide for the process evaluation of a multifaceted, multi-system, universal public health intervention.
