Welcome to Health Level Seven HL7 interview questions. HL7 is an international standard that facilitates a secure way to handle & exchange medical data and acts as a guide for healthcare data handling software.
If you are someone who closely works with healthcare data & implements software to integrate and exchange clinical data, you should know of HL7's importance. If you are about to attend any HL7 or electronic medical records data management interview, your knowledge can be tested with the HL7 interview questions below.
Let's deep dive into the frequently asked Hl7 interview questions and answers.
Clinical data is a pool of health data collected, stored, and used for clinical research. Generally, the clinical data can be collected during the medical course of a patient or clinical trials.
The following are the elements that constitute clinical data:
Clinical data is classified into six major types:
Clinical Data Management (CDM) is one of the essential aspects of the Healthcare system. Clinical data is sensitive information and must comply with many healthcare regulatory standards. The Core aim of clinical data management is to collect high-quality data & meet state, federal, and local regulations.
Health Level 7 is one of the international healthcare standards, and it offers a framework to manage & exchange medical information electronically. It is a framework with predefined standards to collect, store, integrate, and exchange clinical data across different healthcare systems.
In HL7, Z segments are the message segments that store patient or clinical data. Mainly, Z segments are used to exchange proprietary or custom data in HL7 messages related to an organization or system.
The following are the most common HL7 message types:
ADT means patient admit, Discharge & Transfer and it is one of the widely used HL7 message types. It is a primary source for many trigger events such as patient registrations, admissions, discharges, updates, cancellations, patient data merges, etc.
Following are the widely used ADT messages:
ORM is abbreviated as Order Message (ORM), one of the significant HL7 messages. It denotes order for service (ex., Blood panel) or Material (ex., tablets, saline bottle), etc.
Following is the typical information that an ORM message contains:
HL7 ORU message is a widely used HL& message type for sharing observational data. The ORU (Observation Result) 6 results include clinical, lab, and other patient test results.
Non-HL7 messages are extended messages created when customizations are required to meet HL7 standards.
The core difference between HL7 V2 & V3 is that V2 is more flexible and easy to use, whereas HL7 V3 is stricter and focuses more on interoperability.
In healthcare, interoperability is the process that facilitates easy and secure data exchange between healthcare systems. Health Level Seven is a nonprofit organization that develops frameworks to exchange clinical data electronically.
