The cost of implementing two small media interventions to promote HPV vaccination

•The study estimates the costs of parent-targeted HPV vaccine education intervention.•Photonovella cost $88 per participant.•iPad based tailored interactive multimedia intervention cost $108 per participant.•Future programs can reduce recruitment cost by focusing only on those eligible.

ObjectiveTo 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.MethodsWe 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.ResultsThe 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.ConclusionThe 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.
