Social engagement in health encompasses the idea of involving (parts of) society as full partners in the decision-making regarding both development and implementation of health technologies. Evidence shows that patient engagement is linked with fewer adverse events, better patient self-management, fewer diagnostic tests, decreased use of healthcare services and shorter lengths of stay in hospitals. Matching the escalating healthcare requirements to face the ongoing societal and economic challenges regarding access and coverage to (new) health technologies is not an easy task for health providers.

We conducted a systematic review (CRD42017068714) designed to address the institutional implementation of social engagement by the Brazilian Ministry of Health. All systematic reviews were evaluated using the new version of AMSTAR and, once all findings are synthesized, we will use the GRADE-CERQual approach to assess for confidence.

From 399 publications that met the inclusion criteria, 80 described the implementation of social engagement during the development and implementation of (new) health technologies at various levels (local, regional, national, supranational), countries and for different health technologies and social actors. The remaining 319 publications constitute case studies describing barriers and enablers to implementing social engagement in HTA and coverage decision-making processes. By mapping barriers and facilitators, we explored effectiveness and sustainability, further observing how citizen science-based strategies can ultimately reform health service delivery by innovating the social engagement in health technology development and implementation.

This systematic review addresses the know-do gap on social engagement in health technology development and implementation, from a global perspective, as a way of improving the Brazilian Ministry of Health's HTA activities and enabling a Brazilian strategy to reform health service delivery. Enabling social engagement as early as possible, during all the stages of the development cycle, grants a more effective and sustainable health care system.
