Sistema blockchain para gerenciamento de solicitação de medicamentos por via judicial

Abstract

Judicial demand for medication overloads the Brazilian Unified Health System (SUS), and duplicate requests may occur due to different possibilities in the flow of care. The patient of the Unified Health System (SUS) who needs medication and cannot find it in the public assistance network, can acquire it through the opening of a judicial process at the Public Defender’s Office. After the petition, the process is forwarded to one of the health departments where the drug is purchased and provided to the citizen. To provide the service, the organizations work together. According to exploratory research carried out at the Municipal Health Department of Salvador with pharmaceutical management, there is no integration between the information systems of the judicial body and the health departments. This lack of communication causes some problems in the execution of the service, such as duplicate requests and consequent loss of revenue, as the patient can request from more than one office and obtain the drug. The fragile audit is another problem in this context, as each organization maintains its own system and database with a centralized architecture, where information can be deleted or changed with relative ease. The use of blockchain can allow better traceability, making the management of petitions decentralized, secure, resilient and auditable, providing the economy and transparency necessary for the process. The objective of this work is to present the JudMed blockchain system that works through a smart contract that will manage tokens associated with the lawsuits on screen. It is a unified system to integrate organizations in a safe, resilient, decentralized, highly auditable way and capable of guaranteeing that each public entity performs only the operations inherent to its work process. As a result of the integration, the lawsuit gains traceability and the data obtained provide metrics to improve the service and the service to the citizen who waits for more than 900 days to obtain their remedy. The final product of this proposal is composed of the network between organizations, web API for the operations interface, web system for the execution of functions and a smart contract that works like the digital contract to guarantee the correct execution of the business rules that govern the service. . A proof of concept was carried out in a simulated environment and validated with managers and specialists from the Salvador Health Department, and the perception of this proof indicates that the use of JudMed can provide better control of the movement and management of the medication request with significant gains to the process of the Health Unic System.
