Personal health records (PHRs) have the potential to improve health outcomes but face challenges regarding interoperability, security, and privacy. PHRs could allow individuals to manage their own healthcare by communicating with providers and accessing health information. However, PHRs currently lack standardization and the ability to exchange information between different systems. Addressing issues such as determining security protocols, exchanging data between health information exchanges, and clarifying legal policies will help realize the full benefits of PHRs. Widespread adoption also requires resolving questions over who pays for and controls PHR data. Further research is needed to understand how to best design PHRs and incentivize their use.
