Data-driven disruption in healthcare enables advanced analytical capabilities for near-real-time monitoring, prediction, and prevention. However, existing interoperability standards remain inadequate for large-scale operational systems. An innovative event-driven architectural pattern addresses the requirements for near-real-time healthcare data streaming and corresponding data models. Key streams in acute care and telemetry from medical devices illustrate the application of these concepts.
Research demonstrates that many common event-driven architectural patterns well-known in business domains apply equally to near-real-time infrastructures in healthcare. Data-driven technologies are rapidly disrupting business and government sectors. Purpose-built data pipelines collect, curate, and stage data for near-real-time operational insights into customer and environmental factors. Emerging analytical techniques such as complex event processing, predictive analytics, and machine learning rely on these data streams for service innovation, business performance and resilience, fraud detection, and automated response. Similar capabilities are desirable in healthcare, whether for monitoring ICU patients, predicting hospital readmissions, preventing clinical deterioration, detecting adverse events, optimizing resource allocation, or curtailing the spread of disease. Nevertheless, the healthcare sector has not yet realized these advanced operational insights. The primary reason is the lack of sufficiently low-latency, scalable healthcare data streams. Drivers of change include research demonstrating suboptimal patient outcomes resulting from failure to act on existing evidence, the infectious nature of COVID-19, concerns regarding healthcare system capacity, and a growing risk of influenza-H1N1 co-infection.
