GEEs linear model of the absolute increase or decrease in proportion of visits kept, intervention minus preintervention year, adjusting as reported in Table 1, including numbers of scheduled visits in each year.

Gained or lost in the intervention year. Calculated as the product of the number of scheduled visits in the intervention year × the adjusted difference in year–year proportion of kept visits.

For the individual sites, the dollar values of visits are calculated from revenue received from third-party payments for a 12-month period. Revenue was a mixture of FFS revenue and capitation payment revenue.

§

Includes training costs at $2400 [includes 2 trainers, preparation time, and delivery of training ($100 per hour, and travel costs)] and $250 to print 25 posters, 2000 brochures, and 50 pocket guide message reminders.

A hypothetical clinic that experiences 7466 scheduled visits in the intervention year (average of the 6 clinics), an average number of kept visits gained based on the 6 clinics, the median per-visit revenue across these clinics, and the average response to the intervention.
