Mergers in the healthcare industry sound promising—improved patient care, reduced operational costs, and broader reach. But for anyone who’s been through one, you know it’s not all smooth sailing. One of the biggest headaches? Data incompatibility. When two hospitals or health systems merge, they often use different Electronic Health Record (EHR) systems. That’s where chaos begins. Imagine trying to align two entirely different patient record formats, different coding systems, and distinct workflows—all while maintaining HIPAA compliance and patient safety.
And the worst part? This isn’t a one-time issue. Every new partnership can reignite the same data drama. That’s why Fusion’s FHIR implementation in healthcare is becoming a game-changer. With a well-structured FHIR server, organizations can bridge data silos, enable smooth EHR integration in mergers, and support real-time interoperability in healthcare.
In this blog, we’ll break down how Fusion’s FHIR for data sharing works, why it matters in mergers, and how it tackles your real-world data problems.

The Messy Reality of Healthcare Mergers
Let’s say Hospital A and Hospital B decide to merge. Their vision? Unified care. Their reality? Systems that refuse to talk to each other. Hospital A uses Epic. Hospital B uses Cerner. The IT teams are pulling all-nighters just to get patient histories, medication lists, and imaging data to sync.
Here’s what typically goes wrong:
- Duplicate records due to incompatible formats.
- Lost or inaccessible patient data.
- Delays in care due to manual data entry.
- Compliance issues with data security protocols.
That’s not just inefficient—it’s dangerous. When patient records aren’t accurate or accessible in real-time, it can lead to medical errors. This is exactly why FHIR implementation in healthcare has taken center stage.
Common Data Incompatibilities in Healthcare Mergers
Here are the common types of data incompatibilities that occur:
1. Different Data Formats
- One system might store dates as DD-MM-YYYY, another as MM/DD/YYYY.
- One EHR might use XML, another JSON, or even flat files (CSV, TXT).
- Lab results, diagnoses, or images may be stored and structured differently.
2. Varying Data Models and Schemas
- Hospital A might store patient allergies under one field, while Hospital B has it split across multiple fields.
- Medication lists might be structured differently: one may separate dosage, route, and frequency, while the other bundles them together.
- One EHR might allow free text for “diagnosis,” while another requires structured ICD-10 codes.
3. Inconsistent Terminologies and Coding Standards
- Different use of medical vocabularies like ICD-10, SNOMED CT, LOINC, or CPT.
- One system might refer to “Myocardial Infarction,” another as “Heart Attack,” and another by ICD-10 code “I21.”
- This makes matching or comparing data extremely difficult without standardization.
4. Data Access and Security Protocols
- Different authorization/authentication mechanisms (OAuth, SAML, etc.).
- Some systems may encrypt data differently or limit API access to specific endpoints.
- During a merger, these differences block smooth data flow or even full access.
5. Duplicate or Incomplete Records
- A single patient might be listed multiple times across systems under different IDs.
- Demographic information (e.g., name, address, phone) may be outdated or missing in one system but current in another.
- Merging records without introducing errors becomes difficult.
6. Workflow Incompatibilities
- Some data is created or updated based on workflows unique to a specific system.
- For instance, lab orders, radiology reports, or discharge summaries might be triggered differently, resulting in missing or mismatched data during integration.
7. Lack of Interoperable Interfaces
- Legacy systems may not have APIs or web services at all.
- Others might have proprietary APIs that don’t conform to open standards like FHIR.
- This makes real-time communication and integration very hard.
8. Time Zone and Locale Issues
- Systems across regions might store timestamps in different formats or time zones.
- Medication timings, appointment records, or treatment durations might get misaligned if not normalized.
9. Patient Matching Errors
- If two systems don’t follow the same identifiers or master patient index (MPI), it can lead to:
- Mismatched patients
- Missing records
- Privacy issues
These incompatibilities don’t just slow down the merger process—they can have real clinical consequences: duplicated tests, misdiagnosis, delayed treatment, or in the worst case, patient harm.
This is exactly why FHIR implementation in healthcare is such a critical solution. FHIR standardizes data, offers APIs for integration, and helps unify different systems under one interoperable framework
What is FHIR, and Why Is It a Big Deal?
FHIR implementation in healthcare is a data standard developed by HL7 to simplify the exchange of healthcare information across systems. But what makes it different from older standards like HL7 v2 or CDA?
It’s modern, modular, and API-friendly—think of it as the “Spotify of FHIR for data sharing” compared to the “cassette tape” of old-school EHR systems.
Here’s what makes FHIR implementation in healthcare awesome:
- It uses web standards like REST, JSON, and XML.
- It allows developers to create lightweight APIs for easy integration.
- It’s extensible, so it adapts to your organization’s unique data needs.
- It enables real-time access to patient data across different platforms.
So, when it comes to EHR integration in mergers, FHIR implementation in healthcare eliminates much of the manual rework that bogs teams down.
FHIR Servers: The Backbone of Integration
A FHIR server is like the interpreter in a multilingual meeting. It stores healthcare data in FHIR format and enables systems to exchange that data effortlessly, regardless of their original architecture.
During a merger, when you’ve got different EHRs trying to “talk,” a FHIR server becomes the central hub. It translates and shares data between systems using standardized FHIR resources (like Patient, Observation, AllergyIntolerance, etc.).
Key Features of a FHIR Server:
- Data normalization: It brings all incoming data into a common format.
- APIs for sharing: It lets EHRs fetch or send data through secure, RESTful APIs.
- Scalability: Whether you’re integrating two clinics or ten hospitals, it scales easily.
- Security & Compliance: Built-in access control ensures HIPAA compliance.
Without a FHIR server, FHIR implementation in healthcare can’t deliver its full potential. With it, you can rapidly achieve interoperability in healthcare—which, let’s face it, is the holy grail in mergers.
