The text discusses the issue of fragmentation in healthcare systems, where different organizations struggle to share and access patient data effectively. To address this problem, it highlights the importance of interoperability and communication standards, such as Fast Healthcare Interoperability Resources (FHIR). FHIR enables semantic interoperability between independent healthcare institutions, allowing for effective communication and exchange of healthcare data. MongoDB is mentioned as a document database that can be used to build FHIR applications, providing a natural fit for storing and retrieving data in a JSON schema. The text also touches on the trend of healthcare app-ification, which clashes with legacy architectures, but notes that MongoDB's iterative approach to modernization can help reduce risks and unlock developer productivity. Finally, it emphasizes the need for a holistic view of patient care, where interoperable healthcare records and communication standards enable longitudinal patient records and transform legacy infrastructures into modern data platforms.
