In the age of artificial intelligence and advanced cloud computing, it’s surprising how one relic from the past continues to hold its ground in healthcare—fax machines. Despite the digital transformation sweeping across industries, faxing still plays a major role in medical communication. As of 2025, approximately 70% of healthcare providers continue to use fax machines to exchange medical information. This creates an interesting paradox: the industry striving for real-time interoperability still relies on paper-based systems.
So, how can healthcare systems bridge the gap between legacy fax communications and modern digital standards like FHIR? The answer lies in fax-to-FHIR integration, which transforms traditional faxed documents into structured, usable data within interoperable health systems.
Let’s explore how this integration works, why it’s a critical step for true interoperability, and how FHIR-based data standardisation is turning static documents into actionable information.

Why Healthcare Still Relies on Fax
Faxing remains prevalent in hospitals, clinics, and physician offices for several reasons. These include:
- Legal familiarity: Faxed documents are often considered secure and admissible in court.
- Lack of digital infrastructure: Not all providers have advanced EHRs or interoperability solutions, especially in smaller practices.
- Wide compatibility: Fax machines can send and receive documents from nearly any healthcare facility, regardless of their digital capabilities.
But faxes are notoriously inefficient for data processing. They are static, non-structured, and require manual entry, which increases administrative burden and the risk of errors.
The Interoperability Roadblock
Interoperability in healthcare means patient data flows seamlessly across systems, enabling care teams to collaborate effectively. However, faxed documents create a bottleneck where:
- Manual workflows slow down decision-making
- Critical data buried in images or text blocks
- Lack of structured formats blocks integration with EHRS and HIEs
This is where the shift from paper to structured electronic data becomes vital. And that’s where FHIR-based data standardisation comes into play. It converts disparate formats—PDFS, faxes, even handwritten notes—into FHIR-compliant data objects. This allows interoperability tools to:
- Index data correctly in EHRS
- Trigger workflows automatically
- Feed insights into clinical decision support systems
By mapping faxed content into standardized FHIR resources, healthcare providers can access accurate, structured data that can move freely across platforms.
How Fax-to-FHIR Integration Works
Bridging the gap between paper-based faxing and digital FHIR data involves multiple steps. Here’s a simplified flow:
1. Fax Reception and Digitization
Incoming faxes are received via electronic fax systems or cloud fax APIs. These digitized versions are then passed to Optical Character Recognition (OCR) software.
2. OCR and NLP Processing
OCR extracts text from fax images, while Natural Language Processing (NLP) tools identify key medical entities such as patient names, medications, diagnoses, or lab values.
3. Data Mapping to FHIR Resources
The parsed data is structured into FHIR resources like Patient, Observation, Condition, or MedicationRequest. For example:
- A lab result in the fax → FHIR “Observation”
- A prescription refill note → FHIR “MedicationRequest”
4. Validation and Integration
These FHIR resources are validated against schema and business rules before being pushed into EHRs or shared across HIEs (Health Information Exchanges).
Benefits of Fax-to-FHIR Integration
Transforming static faxes into interoperable data delivers measurable improvements in clinical and administrative workflows:
1. Reduced Manual Data Entry
By automating data extraction, clinicians no longer need to retype faxed lab results or referrals into EHRs. This frees up staff time and lowers error rates.
2. Faster Care Coordination
Because structured data is instantly usable by other systems, it can trigger alerts or notifications for care teams to follow up, ultimately reducing care delays.
3. Improved Patient Safety
Important information such as allergy data or medication changes can be processed faster, which minimizes the risk of adverse drug interactions.
Long-Term Digital Transformation
This approach allows healthcare organisations to modernise without completely overhauling legacy systems. By doing so, Fax-to-FHIR acts as a bridge toward full interoperability.
Emerging Technologies Powering Fax-to-FHIR
The growing demand for interoperability is driving innovation in fax-to-FHIR tools. Some of the technologies making this possible include:
- AI-Powered NLP Engines: Recognize medical terms and context in free text
- FHIR Mappers: Automatically convert parsed data into FHIR-compliant resources
- Cloud Fax APIs: Seamlessly receive faxes in digital format, such as via eFax or SRFax
These technologies allow healthcare providers to convert decades-old communication methods into actionable digital records.
Fax-to-FHIR as a Stepping Stone
While many organizations dream of fully digital, cloud-native systems, the reality is that healthcare transformation happens in stages. Fax-to-FHIR isn’t a final destination—it’s a transitional phase that helps organizations move from legacy systems to modern interoperability.
By adopting FHIR-based data standardisation, organisations can:
- Build longitudinal patient records
- Enable predictive analytics
- Share care plans across different providers
- Support value-based care models
Fax-to-FHIR, therefore, is not just a workaround—it’s a meaningful first step toward a more connected healthcare ecosystem.
