Self-Sovereign Identity (SSI), a Blockchain-based technology for digital\nidentity management, is a promising concept for handling health data. It could\nrepresent a step forward in empowering users, granting them control over their\ndata. This work conducts a systematic literature review to investigate\nstate-of-the-art measures based on SSI and Blockchain technologies for dealing\nwith electronic health records (EHRs), identifying gaps, and determining the\nkey questions for future research. As a result, this review shows a growing\ninterest in Blockchain methods to handle EHRs, but few works consider using the\nself-sovereign identity approaches. The results obtained in this work also\nsuggest that: Blockchain technologies provide a viable alternative to deliver\nEHR solutions such as patient monitoring, healthcare data trading, and\nprescription control; consolidated Blockchain technologies are the preferred\ncore components of most effective strategies; keeping raw health data off-chain\nhelps to create scalable solutions; health data standards make searching\nmedical records in Blockchain structures feasible; Smart Contracts are\nessential components of Blockchain-based EHR solutions; the concepts of data\nownership and Self-Sovereign Identity have been neither adequately defined nor\nemployed in the health context.\n
