APIs vs HL7
EHRs have used HL7 technology for formatting information to share data. Since it is limited as it relies on data messages, configuring it with a more advanced interface is necessary. Since its creation took place in 1989, it is not surprising that HL7 is clunky, time-consuming, and does not produce the desired results. Today, EHRs need more advanced systems for sharing data even with non-clinical applications such as cloud patient portals and mobile health portals; HL7 is not compatible with all the apps.
APIs allow easy sharing of data within the systems’ databases. It provides an easy-to-use interface, so an authorized application can send and receive data properly. It enables the third party to exchange data with EHR. It makes APIs more agile and facilitates data sharing.
Fast Healthcare Interoperability Resources: What is it?
FHIR (Fast Healthcare Interoperability Resources) development began in 2012 to tackle market needs for easier, better, and faster methods to exchange the ever-growing healthcare data. It is an interoperability standard and defines how health data can be transferred between systems securely, regardless of its storage place.
With FHIR, medical software developers can leverage major vendors such as Google, Apple, or Microsoft to build applications. They can also use free, downloadable tools, along with libraries and reference servers. Furthermore, FHIR uses REST (Representational State Transfer) as the basis of API and for data transfer. FHIR RESTful API is designed to retrieve only the desired electronic data from the system, rather than returning an entire bundle of ePHI.
Third-party applications can be integrated by using FHIR API into healthcare software such as EHR, and then the medical data can be fed directly into the provider’s workflow. Apart from this, SMART on FHIR is another approach to assemble data longitudinally so that healthcare providers no longer have to switch between different apps to view the complete patient history.
SMART (Substitutable Medical Applications and Reusable Technologies) is a standard to solve interoperability issues, similar to FHIR. Now, SMART on FHIR is built to offer a platform to develop, launch, and access FHIR applications.
Challenges of APIs in Healthcare
Some challenges come along with all the benefits that APIs provide to the healthcare sector. Healthcare facilities use a complex combination of apps, systems, and technology. Since these systems are more hostile to change, it has become challenging, as the systems may turn old-fashioned with time because they fail to be compatible with modern technology.
Moreover, data sources, technologies, and attributes can change when updated, which creates the need to reinvent ETL– extract/transform/load scripts. If any system uses numerous APIs, transforming data to a readable format may take months and years.
Another major drawback of APIs in healthcare is the lack of design, proper testing, and monitoring tools. It also lacks continuous feedback. These are significant reasons that stop developers from designing a more efficient healthcare API system to solve the challenges faced.
Since testing is a challenge, coordinating tests with companies and agencies is another hassle. Healthcare systems have a complicated data flow that may be difficult to replicate. Therefore, developers must determine an efficient method of testing the API to ensure it provides accurate results.
What Barriers Do Healthcare Brands Face While Introducing APIs?
