A. Live Counselor Delivered Booster-based InterventionB. SMS Delivered Booster-based InterventionC. IVR Delivered Booster-based InterventionVariation in the distribution of types of costs across models was similar for each intervention. All four implementation scenarios have similar start-up and participant-level costs. The NGO scenarios have higher intervention-level recurring costs (i.e., program oversight, staff salaries and benefits, connectivity and recurring office expenses) compared to the MOH scenarios. Counselor-level costs (i.e., counselor salaries and benefits, as well as office furniture and supplies for counselors) differed across all scenarios and were higher for NGO scenarios compared with MOH scenarios and higher for stand-alone scenarios compared to integrated scenarios.
