Electronic health records (EHR) aim to improve healthcare and processes for providers and patients on a number of fronts. In an ideal situation according to HealthIT.gov, the clinician benefits by having quick access to patient records and alerts, the ability to quickly and accurately report, and a path to safer prescribing. Patients should be able to spend less time filling out duplicative forms at clinics, have prescriptions sent automatically to pharmacies, and gain easier access to specialist referrals.
The International Journal of Innovation and Applied Studies points out that interoperability can work toward a resolution to several current problems including patient record accessibility and consolidation, and healthcare costs. As far as getting patient information and all available information when it’s needed, the report “estimated that 18% of medical errors that result in an adverse drug event were due to inadequate availability of patients’ information.” Healthcare costs are reduced when different entities can share and communicate common data and could save up to $77.8 billion annually.
Given the potential benefits, there are still opportunities to achieve interoperability. For example, not all healthcare organizations are using EHRs so data isn’t being collected consistently across the board. In 2014 there was an increase in the percentage of hospitals with EHRs. However, only 39% of physicians reported that they share data with other providers. Even though the data is available to share, some EHR users may still be living in a silo and haven’t reached full adoption. In addition, existing specification standards have not promoted interoperability. Even though there is data is available to share, few providers are tapping into that information.
To help increase data sharing, more attention is being paid to FHIR, or Fast Healthcare Interoperability Resources. FHIR stems from HL7 (Health Level Seven) data exchange and information modeling standards. HL7 has been around since 1987 to develop families of standards used to automate healthcare data sharing with the goal to improve patient care. FHIR builds upon the interoperability uses of HL7 and takes into consideration the changes in technology and requirements. According to the Office of the National Coordinator for Health Information Technology (ONC), FHIR is used to enable data access, is used as the container to return query results, and will be used to build necessary security and privacy controls.
FHIR combines what are called “resources” — also known as an instance of data – that define data and are used for specific content. Within a resource are characteristics including “a common way to define and represent them, building them from data types that define common reusable patterns of elements, a common set of metadata, and a human readable Read more from originating source…
