To estimate the cost of implementing lay health worker delivered print-based photonovella intervention and iPad-based tailored interactive multimedia intervention (TIMI) to promote Human Papillomavirus (HPV) vaccine uptake and completion among Hispanic parents of daughters 9–17 years old.
We recruited 301 participants in control, 422 in photonovella, and 239 in TIMI clinics. Intervention costs were estimated using micro-costing from the societal perspective. Cost included time spent planning, training the promotoras, recruiting study participants, and delivering the interventions. Overhead for utilities and project administration was estimated at 30% of direct costs.
The total cost per person for the photonovella and TIMI interventions were $88 and $108, respectively. Less than 10% of costs were fixed and therefore the average cost estimates were insensitive to the size of the target groups.
The electronic medium for HPV vaccine education was 23% more costly than the standard low-tech print based approach. The cost difference should be considered relative to the effectiveness of these methods in achieving increases in immunization rates. The cost estimates provide information for cost-effectiveness and budget impact assessments of new HPV immunization intervention programs.
