Study goals
This study aims to systematically review technologies applicable to Healthcare 4.0 and 5.0 in Brazil’s SUS, analyzing applications, benefits, and limitations in patient support, and identifying technical, organizational, political, and socioeconomic challenges for their implementation in the country.
Relevance / originality
This research contributes by integrating Healthcare 4.0 and 5.0 paradigms into Brazil’s SUS context, providing an original analysis of patient support technologies and mapping socio-technical barriers, guiding public policies and strategies for an equitable digital transformation in healthcare.
Methodology / approach
The study adopts a systematic literature review, following PRISMA 2020 guidelines, with searches in Scopus and Web of Science databases, covering 2011–2025. The analysis includes narrative synthesis and thematic analysis to identify patterns, applications, and challenges of technologies in Brazil’s SUS.
Main results
The analysis identified an evolution from Healthcare 4.0, focused on operational efficiency, to Healthcare 5.0, emphasizing personalization and sustainability. Technologies such as IoMT, AI, Big Data, Blockchain, and Digital Twins show potential but face technical, financial, cultural, and political barriers in SUS.
Theoretical / methodological contributions
The study expands the debate on integrating Healthcare 4.0 and 5.0 paradigms in the public sector, providing an analytical framework to assess technologies in SUS and highlighting methodological gaps in cost-effectiveness studies and regulatory impacts on digital health transformation.
Social / management contributions
The study guides managers and policymakers in the gradual adoption of digital technologies in SUS, balancing investments in infrastructure, training, and governance, aiming for digital inclusion, equitable access, and strengthening of the National Health Data Network (RNDS).
