*The training cost was amortized over 3 years using 5% discount rate, and therefore the training cost for each calendar year was $3,883.20, as shown in the additional file 1. This training cost for five facilitators would be totally fixed for a 3-year period. Even if these 5 facilitators were to conduct this activity for the entire flu season, and thus serve more than 53 practices, this cost would not change.

¹ Costs for the 5-week intervention based on the actual 5-week length of the project.

²Assume that intervention lasts 3 months (13 weeks) during flu season. All figures except the training cost were obtained by converting the 5-week totals (that apply to our particular intervention) listed in third column to weekly rates and then multiplying by 13.

³Assume that intervention lasts one year (52 weeks). All figures except the training cost were obtained by converting the 5-week totals (that apply to our particular intervention) listed in third column to weekly rates and then multiplying by 52.

⁴ Costs for the 5-week intervention based on the actual 5-week length of the project and the training cost was not amortized.
