What Is a Health Information Exchange?
Health Information Exchange (HIE) is a system that enables healthcare professionals and organizations to share and access crucial patient medical information securely.
In this article, we will talk about why health information exchange is important, its properties, and practical examples.
Why Health Information Exchange is Important
Health information exchange is crucial because it empowers doctors and care systems to share vital medical information digitally. It improves access to data and patient records. It also supports better coordination.
Other important reasons include:
Improves access to data and patient information
Providers and clinicians benefit from improved data access, as it enables the sharing of critical information needed to make informed decisions about diagnostics and treatment plans.
Furthermore, HIE reduces the need for repetitive testing, helping minimize duplicate imaging and unnecessary procedures. This leads to lower healthcare costs and reduced exposure to risks, such as radiation, for patients.
In addition, anonymized Protected Health Information (PHI) is valuable for healthcare and population health researchers, as it provides detailed insights into a patient’s overall health. Across healthcare systems, improving access to this data supports better understanding of care patterns and outcomes.
For example, in the US, increased adoption of HIE has enabled greater access to PHI in emergency departments. It is where patients most frequently access test reports and discharge summaries.
Lessens medication errors
Access to a complete medication list allows doctors to avoid prescribing drugs that could adversely react with each other and/or with the patient (i.e. allergies). Clinical outcomes, such as the elimination of 70% of adverse drug events become possible.
Safeguards public health
Health information exchange identifies patient data patterns and trends to help public officials track and contain infectious diseases. Two-thirds of health information organizations (HIOs) send electronic lab results and records to health agencies.
As a result, they can better monitor vaccine coverage and reduce missed cases, especially for notifiable diseases such as TB and HIV.
If public health connects systems, then it is the health information exchange that connects data as well. The value of health information exchange is felt most when care seamlessly transitions into different contexts. With its help, clinicians need to document and act in real time without strain, especially in emergency settings.
This is the context from which My Emergency Doctor (MED) comes. They struggled with a rising demand for mental health services, long travel time for patients seeking medical help, and burnout. “There has to be a better way,” their founder realized.
So My Emergency Doctor was born, offering a core telehealth platform and flexibility in booking different specialists. Care teams can access specialist support instantly, without fixed staffing overhead. Now, with Heidi by their side, MED enjoys its benefits Heidi and has bigger plans to bring the best possible care to every patient.
“Heidi is easy to work with; the training required is minimal. And seeing a professional medical summary created after an encounter with a patient, which filters out all the unnecessary details and includes clear plans and patient instructions… is a game changer,” recounted Tatiana Lowe, Medical Director.
“If the patient encounter time has already reduced by just three minutes each call, that adds up fast across hundreds of daily ones,” observed Chantel Gallagher, MED Operations Manager.
Characteristics of Health Information Exchange (HIE)
In the United States, 75% of hospitals that participate in an HIO have a shared time and real-time view of clinical information. It has resulted in more informed medical decisions, such as immunization reporting. A recent study indicates that HIOs connected to public health agencies are more likely to support immunization reporting.
It makes them crucial for overall regional health and safety.
Real-time access to HIE is characterized by the sharing of structured data and patient records. It can lead to an overall improvement in care quality. Other characteristics include:
Data Exchange
Globally, the market for HIEs, which allow doctors, hospitals, and pharmacies to securely share patient information, is a leading segment, as noted in a recent market analysis. The core principle behind HIEs is to offer better control over sensitive health information, ensuring its management adheres to all regulatory requirements.
Regional exchanges also benefit, especially with differing laws and infrastructure. For example, if a hospital retrieves a patient’s complete medical history from external providers, when the patient is unable to provide it.
To allow for this, a secure query-based exchange at the emergency department will be used. HIE will enforce privacy rules and consent policies with the exchange happening in an encrypted setting with strict access controls and audit logs, especially in different regions.
Regional Focus
Regional Health Information Organizations (RHIOs) support the secure exchange of health information across hospitals and other care providers. They operate within a defined region, and that region may be a country, state, or city, depending on how care is locally organized.
The goal is simple: ensure the right information is available when and where it is needed to support patient care.
One example is Health Current, which operates in Arizona. Like many successful RHIOs, it brings together clinical stakeholders and funding models to sustain information exchange and sharing across care systems.
Health Information Exchange Examples
According to a recent study on HIOs and their connections with Public Health Agencies (PHAs), common health information exchange examples, particularly during the COVID-19 pandemic response, were heavy on the following:
- Hospitalization information (93%)
- Patient demographics (91%)
- Chronic health conditions (88%)
- Laboratory results (88%)
Other examples are presented below:
Directed Exchange
Direct exchange secures the stable conveyance of health data between providers. This type of exchange is practical for sharing results quickly. Examples include referrals, care coordination, and discharge summaries.
A recent HIO survey shares that 92% of respondents connect directly with independent and health system practices via synchronized, two-way communication. Meanwhile, 89% link up with private hospitals and community health centers or federally qualified health centers. Lastly, 79% have established links with long-term care providers, like skilled nursing facilities.
Query-based Exchange
Query-based HIE uses a “pull” method that allows providers to search, and retrieve clinical information when it is needed. It also reduces avoidable utilizations and was associated with a lower chance of experiencing an ambulatory care sensitive hospitalizations (ACSH).
Emergency room visits and unplanned care encounters, such as sudden illness during vacation, are examples of query-based exchanges. In Canada, the Canadian Health InfoWay facilitates FHIR-based querying to document repositories.
Consumer-mediated Exchange
Patient-controlled Health Information Exchange (HIE) allows patients to manage and share their consolidated health data (e.g., MyHealthRecord in Australia) with providers, payers, and researchers.
Effective HIE is vital for timely, quality care, as it prevents fragmented records that impede informed clinical decisions. This exchange empowers patients by increasing their engagement and enabling them to identify and correct inaccuracies.
Currently, some data transmission relies on less efficient means like faxes or email.
