Interoperable Data Systems

Definition:  

Interoperability is the capacity for information systems to seamlessly access, exchange, integrate, and leverage data. As technological advancement has opened doors to the integration of data from disparate sources, new opportunities exist to build seamless data flow across individual systems. Although historically systems within public health were implemented in isolation without capacity for interoperability, these challenges are being addressed by the ongoing development of data and message standards and technological approaches to facilitate swift and secure exchange of critical public health data among systems, both within and across organizations and geographies. 

National Picture:  

Prior to the COVID-19 pandemic, nearly 70 percent of hospitals were using fax or mail to send patient data, as reported in 2019 by the Office of the National Coordinator for Health Information Technology. As one of public health’s largest data partners, lack of interoperability with hospitals led to data quality issues and required substantial manual efforts to clean and gather complete data. Interoperability with these external systems was enabled via electronic laboratory reporting and electronic case reporting, utilizing message standards for efficient electronic data sharing. Public health agencies are confronting similar scenarios, with many internal programs operating standalone systems for single purposes. Many state, local, tribal, and territorial health departments are actively working to enhance interoperability among internal systems, databases, and external data sources to enable the secure and rapid exchange of more complete data. This work aligns with a goal in the Centers for Disease Control and Prevention’s Public Health Data Strategy to ensure a response-ready public health system.
