The top stakeholders participating in data exchange are ambulatory practices, hospitals, and public health departments. Clinical summaries, test results, discharge lists, medication information, and problem lists are all being exchanged among providers at high rates, and the number of organizations reporting exchange of patient summary care records increased from 52 in 2011 to 70 in 2012.
Of the advanced HIE initiatives surveyed, 86% were exchanging test results, while the exchange of inpatient, outpatient, and summary of care records reached just over 80%. However, public health data reporting hovered around 32%, indicating a need to increase collaboration between providers and public health initiatives.
HIE is not only gaining in numbers, but also in complexity and usefulness. As meaningful use requirements demand more patient engagement and greater information exchange, HIEs are increasingly adapting to facilitate “bi-directional exchange”, which is the ability to both “push” and “pull” patient information. The “push” model simply involves unidirectional messaging between entities, such as a clinician requesting another provider to send over a patient’s record. It is giving way to the “pull” exchange, a query/retrieve model that allows data to be automatically retrieved from other sources without any other entity being involved.
“Bi-directional exchange is critical to the daily needs of providers and hospitals alike,” say the authors of the study, “both of which regularly need to push and pull patient data to and from other systems. Today, many HIE initiatives provide both of these capabilities in response to the priorities and needs of participating stakeholder entities.” Of the HIE initiatives surveyed, 104 use a push model, while 112 use a query model. Eighty-seven report using an end-to-end integration model, which interfaces between systems to create a seamless exchange, enabling the automatic synchronization of data without any user effort involved.
2012 was a year of significant growth for HIE in the United States, and the trend towards interoperability is likely to continue at a rapid pace. As HIE initiatives move through the seven stages of development towards true sustainability, innovation and the quality and variety of services offered will increase. HIEs will become more comprehensive as exchange technology improves and more healthcare organizations join the initiatives.
