A Prospective Programmatic Cost Analysis of Fuel Your Life: A Worksite Translation of DPP.

Objective: An accounting of the resources necessary for implementation of efficacious programs is important for economic evaluations and dissemination.

Methods: A programmatic costs analysis was conducted prospectively in conjunction with an efficacy trial of Fuel Your Life (FYL), a worksite translation of the Diabetes Prevention Program. FYL was implemented through three different modalities, Group, Phone, and Self-study, using a micro-costing approach from both the employer and societal perspectives.

Results: The Phone modality was the most costly at $354.6 per participant, compared with $154.6 and $75.5 for the Group and Self-study modalities, respectively. With the inclusion of participant-related costs, the Phone modality was still more expensive than the Group modality but with a smaller incremental difference ($461.4 vs $368.1).

Conclusions: This level of cost-related detail for a preventive intervention is rare, and our analysis can aid in the transparency of future economic evaluations.
