Evaluation of Immunobiological Cold Chain Costs.

Background and Purpose: Studies assessing the costs of the immunobiological cold chain (CC) are scarce. Therefore, the factors that influence the allocation of resources in this process are not known. The objective of this study is to determine the cost of the immunobiological CC. Methods: The Health Economic Assessment study was carried out in Minas Gerais, Brazil, between 2021 and 2022. The unit of analysis was the municipal level of the CC. The perspective of the Public Health System (Sistema Único de Saúde) was considered as a funder, the year 2021 was considered as the time frame, and the period of 1 year was considered as the time horizon of the analysis. Direct medical, nonmedical, and indirect costs were included. A mixed technique was used involving micro- and macrocosting and sensitivity analysis to identify the influence of the main categories on the final cost. Results: The total cost was USD 20,014,545, with nonmedical direct costs being the most representative (61.24%). Human resources were the most influential items, representing 76.43% of the total cost. Conclusions: The most influential items should be those of greatest concern and planned by managers to make the CC more efficient.
