Fragmentation in global healthcare systems arises from a lack of interoperability among various organizations, leading to issues such as misdiagnosis and service duplication, which negatively impact patient outcomes and add economic burdens. A solution to this problem is the implementation of longitudinal patient records (LPRs), which provide a comprehensive view of a patient's healthcare history and facilitate effective data sharing across healthcare entities. Fast Healthcare Interoperability Resources (FHIR) is a schema that supports semantic interoperability by defining standards for healthcare data exchange, allowing for effective communication between independent institutions. MongoDB, with its JSON-based document model, is well-suited for developing FHIR applications, offering tools like the Exafluence FHIR API to enhance real-time data interchange and improve project velocity. The move towards digital healthcare necessitates cloud adoption, and MongoDB Atlas supports this with a secure, multi-cloud platform compliant with industry regulations like HIPAA and GDPR. By promoting interoperable healthcare records, MongoDB aims to provide a holistic view of patient care and address the challenges of transforming legacy systems into agile, modern data platforms.
