Health Technology Assessment (HTA) is a multidisciplinary field of policy analysis that examines the clinical, social, ethical, and economic implications of the development, diffusion, and use of technology in healthcare, taking into consideration aspects such as efficiency, effectiveness, safety, cost, and cost-effectiveness, among others. Although HTA should primarily consider the social, ethical, and legal impacts associated with technology, other basic attributes (efficacy, effectiveness, safety, and cost) end up taking precedence over the previous ones.  But with the increasing emphasis on the engagement of patients as full partners in taking care of their own health, there is a need to establish effective means for their involvement in the decision-making process. The participation of society in HTA is crucial and needs to be implemented.  In Brazil, community participation is one of the guidelines of the Brazilian Public Health System (SUS) present in the Federal Constitution of 1988.  It’s also one of the principles outlined in Laws 8,080/1990 and 8,142/1990, that provide for community participation in the SUS.  In 2011, Law 12,401 was enacted, officializing the participation of civil society in the process of incorporating technologies in the health system.  However, it is necessary to analyze, discuss, and question how to actually introduce the patient and public preferences into HTA processes and in the process of incorporating new health technologies within the current Brazilian context (SUS perspective), given how important the broad suitability of new health technologies is. This is the aim of an ongoing study that will provide guidance to support HTA units in the Brazilian Ministry of Health and abroad in their decisions regarding patient participation.
