In 2022, the Ministry of Health and the National Supplementary Health Agency (ANS) launched an initiative to standardize data sharing between supplementary health service providers in Brazil. It's called Open Health.  

Inspired by data sharing experiences proposed by bodies in other regulated markets, such as Open Finance, developed by the Central Bank of Brazil (BACEN), the proponents of Open Health aim to stimulate competition between supplementary health service providers and improve the quality of services in this sector. It is assumed that reducing information asymmetry between agents in this market will try to make services more efficient and stimulate the development of solutions that benefit the population. 

The initiative has prioritized axes to be worked on, such as transparency of open data and improving the user experience. Given that Open Health is still an initiative in its infancy in Brazil, it is appropriate for academic research to look at the model that is being developed in order to critically evaluate it. In addition, academic research can contribute to the creation of the model by developing proposals and guidelines aimed at improving it, based on similar successful national and international experiences, especially initiatives linked to data sharing in the financial sector (Open Finance), which are taking place in Brazil.
