If you’re interviewing for a position in healthcare IT, you may be asked questions about Fast Healthcare Interoperability Resources (FHIR). FHIR is a set of standards that define how electronic health information should be exchanged between systems. It’s designed to improve patient care by making it easier for different healthcare organizations to share data.
Knowing how to answer questions about FHIR can help you impress the hiring manager and land the job. In this article, we’ll discuss some common FHIR interview questions and provide tips on how to answer them.
HL7 Interview Questions 1
ORM messages are chosen to obtain information that comprises any request for clinical components. The transmission of ORM information occurs amongst the software application system putting the order and the health care application loading the purchase. The device that acquires the message for the HIS software plan is generally considered the ‘filler’ of the purchase.
ORUs, or even observational record notifications, are usually the outcome information from the “filler” utilization of the ORM message. They include sizes and beliefs from operations, identical to checking out outcomes from the lab or the radiology division. ORU messages can also be used for connecting demands and results to medical preliminaries.
It is utilized to ‘astound for’ truths that don’t live well-balanced right into the HL7 Standard information definitions. Z segments may be embedded into any message. There are no limitations to the records consisting of in Z segments or inside the style of Z segments bore in mind for HL7 information.
HL7 established character sequences indicate “special” characters that aren’t allowed in average HL7 messages. These sequences comprise an identifying symbol followed by zero or more characters and begin and finish with the message’s escape. The escape of the HL7 characters mentioned above is the most typical usage of these escape sequences.
HL7 Interface Engines are software systems tuned to exchange healthcare information in huge varieties of use cases involving disparate systems communicating over different protocols. HL7 Interfaces Engines must adeptly handle data transformation and exchange of not only large batch-oriented data and all versions of HL7 messaging but also highly conversational XML and JSON APIs – including HL7 FHIR.
Healthcare data interoperability is key to the ability of healthcare data to flow securely from one internal or external system to another, as needed, for patient care and patient use. Interoperability in healthcare must handle patient identification and privacy issues, complexities of messaging standards, data silos, legacy systems and technologies, and adaptation to modern applications.
The HL7 Standard specifies a data structure based on trigger events, segments, fields, and data types. Non-standard HL7 messages are created when different systems and applications require customizing and extending the standard. HL7’s structure allows optional fields or additional portions of messages. HL7 allows Z-segments (miscellaneous) for data elements defined locally.
Each HL7 message indicates the healthcare trigger event defined by the HL7 Standard. It defines the specific healthcare information being exchanged in each message type. The HL7 Standard identifies hundreds of data elements for communicating patient demographic, clinical, and financial information and describes the specific set or combination of segments that make up a properly formed message.
HL7 refers to data formats and standards used to structure and share medical data and patient health information (PHI). HL7 messages include information about specific medical or administrative events and are fundamental to interoperability. HL7 standards (e.g., V2, V3, CDA, FHIR) are created and supported by the non-profit standards organization Health Level Seven International. HL7 V2 is the most widely used version of the standard in healthcare.
Yes, it is possible to store or create documents from XML, JSON, RDF, or any other file format using FHIR. This is because FHIR defines a set of resources that can be used to represent any kind of data. So, if you have a document in XML, JSON, or RDF format, you can simply create a FHIR resource that corresponds to that document.
FHIR is a set of standards for exchanging healthcare information electronically. It includes a data model, an XML-based encoding system, and a set of rules for how information should be exchanged. FHIR is designed to be used by a wide variety of healthcare applications, making it easier for different systems to share data.
FHIR defines a number of different resource types that can be used to represent different kinds of data. This includes everything from patient information to clinical observations and diagnostic reports. FHIR also defines a number of different ways that this data can be shared, including via RESTful APIs and HL7 messaging.
FHIR provides a number of benefits for health information exchange, including its ability to support a wide range of clinical and administrative data, its use of standard formats and vocabularies, and its ability to be easily integrated into existing health information systems. FHIR also supports real-time data exchange, which can help to improve the quality and timeliness of care.
FHIR defines the structure of where data should live and how it should look. This standardization makes it possible for different healthcare applications to share data with each other, because they can all reference the same FHIR structure. This interoperability is crucial in ensuring that patients receive the best possible care, as it allows for a more complete picture of a patient’s health history.
8 common questions about HL7 Interoperability: the ‘ultimate IT goal of the modern healthcare system’
As recent talks have Health Level Seven International (HL7) moving beyond IT professionals, the standards process is setting the stage to make a significant impact on usability and workflow. And as more communities are embracing HL7, learning the basic ins-and-outs of the standards process is more important than ever.
Rob Brull, product manager at Corepoint Health, answers eight common questions about HL7.
1. What is HL7? Interoperability, or the back-and-forth exchange of patient health data among different organizations, is seen as the “ultimate IT goal of the modern healthcare system,” when discussing meaningful use, HITECH and the Affordable Care Act, said Brull. “One of the major challenges to healthcare interoperability is defining common standards for structured content of healthcare data and the transport of that data between different systems, created by different vendors,” he said. Creating consensus behind a common healthcare standard is the mission of HL7, which was founded in 1987. “The HL7 Standard was created and has since become widely adopted by vendors worldwide to define content,” said Brull.
2. What is the difference between HL7 version 2 and HL7 version 3? According to Brull, HL7 version 3 (v3) isnt all that similar to HL7 version 2 (v2). “While v2 provides a negotiated framework for developers to easily use and adapt, v3 was targeted to be a stricter standard that aimed to eliminate variances, in an effort to improve interoperability between all users of the standard,” he said. From a technical standpoint, he added, typical HL7 structure data uses “pipes” (|) and “hats” (^), while HL7 v3 is based on XML. “Due to a large embedded v2 base, adoption of v3 is still very slow in the U.S., with [more than] 90 percent of systems and applications still using some form of HL7 v2,” he said. HL7 v3 includes both messages and documents, he added, with v3 documents being called CDA, or clinical document architecture. “While a move to v3 message doesnt appear to be on the horizon, CDA documents have been adopted in meaningful use standards for both Stages 1 and 2,” Brull said.
3. What are Z segments? Z segments contain clinical or patient data that may not be a good fit for other segments of the HL7 v2 standard, said Brull. “Essentially, its used as the catch all for data that doesnt fit into the HL7 Standard message definitions – Z segments can be inserted into any message.” Theyre also one reason why the HL7 Standard is sometimes called a “flexible standard,” he added. “There literally are no limits to the data contained in a Z segment, or in the number of Z segments included in an HL7 message,” said Brull.
