Garau, María LauraVukotich, ClaudiaRoitman, Adriel Jonas2023-05-222023-05-222024978958763721210.58863/20.500.12424/4284655http://hdl.handle.net/20.500.12424/4284655Including health research in a publicly accessible registry provides transparency and reliability for all stakeholders. With this in mind, a transformation process was carried out in the way Research Ethics Committees (RECs) perform their activity in Buenos Aires City, Argentina. In 2019 the Computerized Registry Platform for Health Research of the City of Buenos Aires (PRIISA.BA) was developed. Through it, the ethical and methodological evaluation of the protocols is managed, until the effective issuance of the Committees’ opinion.The platform allows REC to make observations and interact with principal investigators and sponsors. After a study is approved or rejected, it is incorporated into a public access registry. Since its use is mandatory, experience has shown that underreporting has been eliminated, providing the RECs with a management and communication tool, which facilitates their activity. The objective of this work is to share the experience and review the different stages of the process, through which the use of the platform was developed, implemented and consolidated for all the research ethics committees of the public and private sector, from the Ministry of Health of the City of Buenos Aires.spaEditorial Bonaventuriana, Universidad de San Buenaventura Colombia & Globethics PublicationsAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/ethics committeeshealth researchresearch registrymanagementaccess to informationBioethicsBook chapter
