Electronic Health Records (EHRs) contain information such as diagnoses, medications, and allergies of individuals stored in a digital manner.Given the sensitive nature of these information, EHR systems with improper access control may be vulnerable to attacks leading to a breach of confidentiality.Those with strict security controls, on the other hand, limit the accessibility of the records, making them difficult to share said records among various medical institutions and professionals.One approach to addressing the accessibility of EHRs, while not compromising confidentiality and access control, is by utilizing blockchain technol-ogy.The inherent security of blockchains allow it to strengthen existing EHR systems by addressing the limitations previously mentioned.In this research, an Application Programming Interface (API) was developed to integrate an EHR system to a blockchain network.The API includes functionalities such as adding records, sharing and retrieving records, and access control.
