Lack of availability of medicine may results in fatalities and excess of availability generate waste. In order to achieve a balance, public institutions can and should invest in innovative solutions that in turn are economical, efficient and in the public interest. The implementation of the National System of Medicine Control, in 2022, presents an opportunity for the Brazilian Navy to use Datamatrix s bidimensional barcodes to track and control medicines in an efficient and effective manner. However, how do you adapt an already mature supply chain to this change in technology? In this context, the following study has the objective to propose a new model for the Brazilian Navy s Medicines Chain, for which it was necessary to describe the current model, in terms of structure and processes, and to identify the failures of this model that made it unfeasible the proposed adaptation. From these findings, conclusions were generated, which served as the basis for the proposed model. In addition, the study presents the advantages and benefits that the proposed adaptations may represent for the Brazilian Navy s Medicines Chain, especially for its personnel. With the adaptation of its Medicine Chain to the National System of Medicine Control, the Brazilian Navy will become a pioneer, within the scope of the Executive Branch, in the search for drug traceability, improving the quality of the use of public resources and effectively incorporating into the health system the concept of patient safety.
