[Budget impact analysis of the implementation of a bone tissue bank in a Chilean health service]. / Análisis de impacto presupuestario de un banco de tejido óseo en un servicio de salud de Chile.

ABSTRACT

This research aimed to analyze the costs of bone grafting through a bone tissue bank in a Chilean regional health service. Methods: First, we developed a preliminary epidemiological study to obtain the necessary data for the analysis, specifically on bone graft procedures in a local health service (Servicio Salud Concepción). Next, we performed a budget impact analysis. Results: We analyzed a total of 6,252 cc of bone grafts, with a total cost of USD$156,000 per year. We found a potential recovering capacity of 302 ± 16 femoral heads per year from the total hip replacement procedures. Based on these results, bone tissue banks could save USD$145,000 hospital costs annually. Studying a representative health service from Chile, this analysis revealed a dependency on imported bone substitutes and autografts. These requirements can be supplied sustainably by a bone tissue bank based on donations of femoral heads under the current legislation of the Chilean health authority.
