What Is Health Information Exchange and Why Is It Important With HL7

HL7 Health Information Exchange Organizations

HL7, or more precisely the Health Level 7 International organization, is a “not-for-profit, ANSI-accredited standards developing organization that offers a comprehensive framework and related standards for the exchange, integration, sharing, and retrieval of electronic health information that supports clinical practice and the management, delivery and evaluation of health services”.

Before the advent of HL7, Radiology information system (RIS), lab information system (LIS), hospital information system (HIS), and electronic medical record (EMR), had no way of communicating with each other seamlessly. Each system used to speak its own language. However, Health information exchanges, such as the HL7, facilitate safe and reliable exchange of patient health data between healthcare organizations, doctors, insurance companies, and other organizations that are involved in a patient’s chain of care, while maintaining the meaning of the information being exchanged. These exchanges form the foundation for multi-stakeholder partnership, where disparate organizations can collaborate on patient cases to improve healthcare outcomes and enhance patient care.

There are several kinds of Health information exchanges that are possible with HL7 across the US, such as regional, statewide, nationwide, and vendor to vendor. However, regardless of the type, you can think of these organizations as unbiased data trustees that don’t provide care, but leverage cutting-edge technology to deliver clinically relevant, cross-institutional clinical information, improve efficiency, cost-effectiveness, quality, and safety of healthcare delivery, and lower the time and cost of providing clinical information to researchers.

Why Is Health Information Exchange Important With HL7?

Virtually anyone who has ever visited a healthcare provider has experienced the need for interoperability. Providers within a single healthcare organization may be able to share data and patient history through a shared EHR, but if the patient needs to visit a provider outside the scope of that EHR, they find themselves filling medical history forms again. On the other hand, most providers still use fax machines as the means for information exchange within the healthcare industry and feel a deeper need for interoperability.

HIEs play an important role in standardizing information and facilitating exchange between healthcare organizations, making it effortless to share Clinical results, Clinical information, clinical documentation such as transcription and care summary notes, ED notes, discharge summaries, referrals, consulting notes, Medication history, Immunizations, public health data, and Electronic prescribing and refill information. HIEs form a basic level of interoperability among electronic health records (EHRs) maintained by individual physicians and organizations. In fact, most EMR/EHR vendors have already incorporated HIE features and capabilities into their systems with the help of EHR/EMR integration services. Real-time access to patient data enhances the quality of care delivery, curtail hospital readmissions, compromised patient safety, or other unintended consequence, and improve the quality of care coordination.

Standardized health information exchange with HL7 helps alleviate myriad errors prevalent in patient care, and improve quality care. For example, since all healthcare providers within a patient’s line of care can view their medication list through the HIE, it reduces medication errors and eliminates the need for redundant tests or procedures. HIEs eliminates the need for duplicate tests and unnecessary paperwork, and allow caregivers to get access to clinical notes that allow for more effective care and treatment.

Healthcare exchange using HL7 also finds application in research, since it is a reliable source of cross-institutional clinical information. All healthcare information is shared synchronously with HL7, potentially decreasing the time and cost of providing clinical information to researchers.

Lastly, HIEs allow Public health agencies to conduct disease prevention activities with the help of data collected through public health screening and treatment services, as well as data that comes from labs, pharmacies, emergency medical services, local public health agencies, and healthcare providers. Since HIE organizations ensure robust and timely data collection, HIE using HL7 can serve to improve population health.

Types of Health Information Exchange HL7

1.      Directed Exchange

Through directed exchange, health care providers have a secure and timely way of sending alerts and sharing patient data, such as laboratory orders and results, patient referrals, or discharge summaries, with other providers. The data is securely encrypted and is only share between providers who already know and trust each other. Providers can also communicate with each other through a secure messaging format, much like Email. This helps to support use cases such as referrals, care coordination, and transitions of care. For instance, a primary care provider can directly send patient information, such as list of medications, diagnosis, and lab results to another provider when referring their patients. This information reduces duplication of tests, redundant collection of information from the patient, unnecessary visits, and medication errors. HL7 integration solutions facilitate directed exchange by providers.

2.      Query-based Exchange

Query-based exchange in a healthcare information exchange organization that lets providers search for and find information on a patient from other providers. This is generally needed when a healthcare provider encounters a new patient or when the provider hopes to uncover some important information in previous patient records. This form of exchange is especially beneficial for delivering unplanned care. For instance, if an unconscious person comes into the ER, the physician can use this query-based exchange system to access critical pieces of data about that patient, such as medications, recent radiology images, and list of allergens, health complications, contraindication, and so on. If a pregnant woman visits a new doctor, the healthcare provider can easily obtain her pregnancy care record, to ensure the health of both the mother and the child.

3.      Consumer Mediated Exchange

This form of exchange encourages patients to collect and maintain control of their personal health information and access their records online. This form of exchange is used to provide patient centric care, hereby increasing their involvement in their own healthcare and increasing their knowledge and understanding of their health. Patients may need to access their records when they want to share their healthcare providers with vital information, correct inaccurate demographic, medical, or billing information, and keep tabs on their health and insurance information.

HL7 Health Information Exchange Examples

Some examples of HIE through HL7 includes:

ADMISSION, DISCHARGE, TRANSFER (ADT)

These types of health data messages include information pertaining to a patient’s admission, transfer, or discharge status from clinical care settings. These messages keep the patient’s providers alert as to the patient’s current status and are helpful in care coordination and care management. For instance, let’s say that a patient who was present for a non-admitted visit is being admitted after an evaluation. This event changes a patient’s status from non-admitted to admit.

DEMOGRAPHICS

Patient demographics, such as patient name, DOB, gender, preferred language, and race, help to identify each patient. Demographics are a key part of the Continuity of Care Document (CCD) that is used to exchange patient health information.

ALLERGIES

A list of the patient’s medication allergies are included in the CCD to help avoid an adverse reaction with any medications they are currently taking.

MEDICATION LIST

A person’s complete medication list helps providers keep track of medication allergies and adverse reactions. These messages help avoid over-prescription or drug abuse.

ORM

The HL7 ORM message serves to transmit information about an order. This message responds to events that involve changes to an order such as new orders, cancellations, information updates, discontinuation, etc.

RESULTS (ORU)

ORU messages are transmitted in response to an order to provide clinical observations. ORU messages incorporate multiple observations, such as imaging study reports, clinical lab results, EKG pulmonary functions study results, or patient conditions.

HISTORY AND PHYSICAL

A patient’s medical history includes details such as the patient demographics, chief complaints, past health condition, complete medical and family history, list of allergens, medication lists, diagnosis, and physical examination.

IMAGE EXCHANGE

These messages facilitate the exchange of a patient’s diagnostic imaging results among the care team. These exchanges prove to be a bliss in telemedicine and remote monitoring to patients. Not to mention, they reduce costs by preventing test redundancy.
