Interoperability between healthcare systems is crucial for delivering quality services to patients and providers, as it enables the secure exchange of health information across separate entities. However, many healthcare payers face technical challenges in implementing interoperability due to siloed data and legacy communication methods, which can lead to higher administrative costs and limited member experiences. To address these challenges, data streaming technology such as Apache Kafka and Confluent has been used to decouple proprietary monolithic applications and unlock real-time data for use in event-driven microservices. By leveraging data streaming, healthcare payers can improve care coordination, increase efficiency, better analyze data, prevent fraud and abuse, and provide a better member experience, ultimately delivering better patient outcomes.
