Accessing Siloed EMR Systems with FHIR: Connecting to Multiple EMRs

In today’s healthcare landscape, the ability to connect to multiple EMRs (Electronic Medical Records) seamlessly has become crucial for improving patient care, reducing administrative overhead, and driving innovation. However, the diversity in EMR systems, proprietary data formats, and communication protocols has historically made integration a daunting challenge. Enter FHIR (Fast Healthcare Interoperability Resources), the game-changing standard developed by HL7 (Health Level Seven International), which is paving the way for interoperability in healthcare.

The Problem: Siloed EMR Systems

Healthcare providers often use different EMR systems, each designed with unique data structures, interfaces, and workflows. While these systems are essential for managing patient information, they don’t “talk” to each other natively. This lack of interoperability creates data silos, leading to:

  1. Inefficiencies: Manual data entry and reconciliation slow down workflows.
  2. Fragmented Care: Providers may not have access to a complete patient history.
  3. Missed Opportunities: Innovations like patient-facing apps and decision-support tools struggle to integrate across multiple platforms.

The Solution: FHIR as a Universal Language

FHIR offers a standardized framework for accessing and exchanging healthcare information. By leveraging its RESTful API architecture and well-defined data models (resources), FHIR enables seamless integration across multiple EMRs. Here’s how:

  1. Unified Data Access via FHIR APIs Modern EMR systems like Epic, Cerner, and Allscripts have adopted FHIR APIs as part of their platforms. This standardization allows external applications to retrieve and interact with data like patient demographics, medications, and lab results without requiring custom integration for each EMR.
  2. Standardized Resources FHIR resources—such as Patient, Observation, Encounter, and Medication—act as reusable data models. These resources provide a consistent structure across systems, making it easier for developers to query and update data in a predictable way, regardless of the underlying EMR.
  3. SMART on FHIR for Authentication The SMART on FHIR framework adds an additional layer by standardizing the way apps authenticate and gain authorized access to EMR data using OAuth 2.0. This ensures secure, scalable integration while respecting patient privacy and data security regulations like HIPAA.

Benefits of Connecting to Multiple EMRs

  1. Streamlined Care Coordination FHIR enables providers to access and share patient data across different healthcare systems. A specialist in one hospital can view relevant records from another provider’s EMR, ensuring continuity of care.
  2. Simplified Integration for Developers Developers can create third-party applications, such as telehealth platforms or chronic disease management tools, that work with multiple EMRs out of the box. Instead of writing custom connectors for each system, developers interact with a single FHIR-based API.
  3. Empowering Patients Patient-facing apps can use FHIR to aggregate data from multiple EMRs, giving individuals a unified view of their health records. This transparency improves patient engagement and health outcomes.
  4. Faster Innovation The reduced complexity of integrating with EMRs allows startups and innovators to focus on building features that directly improve care delivery rather than wrestling with legacy integration challenges.

Challenges to Consider

While FHIR greatly simplifies the process of connecting to multiple EMRs, it’s not without challenges:

  • Vendor Variability: Not all EMRs implement FHIR in the same way. Developers may encounter slight differences in API behavior across systems.
  • Data Gaps: Older EMRs or smaller providers might not support FHIR, requiring fallback mechanisms.
  • Access Control: Even with FHIR, gaining authorized access to data involves navigating organizational policies and regulatory requirements.

The Future of EMR Connectivity

As FHIR adoption continues to grow, the dream of a truly interoperable healthcare ecosystem is becoming a reality. Initiatives like the 21st Century Cures Act in the United States mandate that EMR vendors provide FHIR APIs to improve data access and patient empowerment. This regulatory push, combined with advancements in technology, means that healthcare organizations can now leverage FHIR to unlock the full potential of their data.

Conclusion

Connecting to multiple EMRs is no longer an insurmountable challenge. With FHIR as the universal standard, healthcare providers, developers, and patients can break down data silos, enabling seamless information exchange and fostering innovation. Whether you’re building a new application or improving workflows in your organization, FHIR offers the tools to bridge the gaps between EMRs and create a more connected healthcare future.

Example Patient Data Stored in a MySQL Database in SQL Format

By Stephen Fitzmeyer, MD

here is an example of patient data stored in a MySQL database in SQL format:

CREATE TABLE patients (

    patient_id INT AUTO_INCREMENT PRIMARY KEY,

    name VARCHAR(50) NOT NULL,

    age INT NOT NULL,

    gender VARCHAR(10) NOT NULL,

    diagnosis VARCHAR(100),

    medication VARCHAR(100),

    medication_start_date DATE,

    medication_end_date DATE

);

INSERT INTO patients (name, age, gender, diagnosis, medication, medication_start_date, medication_end_date)

VALUES (‘John Smith’, 45, ‘Male’, ‘Diabetes’, ‘Metformin’, ‘2021-01-01’, ‘2022-01-01’),

       (‘Jane Doe’, 35, ‘Female’, ‘Hypertension’, ‘Lisinopril’, ‘2021-02-01’, ‘2022-02-01’),

       (‘Mike Johnson’, 50, ‘Male’, ‘Chronic Obstructive Pulmonary Disease’, ‘Albuterol’, ‘2021-03-01’, ‘2022-03-01’),

       (‘Sarah Lee’, 28, ‘Female’, ‘Anxiety’, ‘Sertraline’, ‘2021-04-01’, ‘2022-04-01’);

This creates a table called “patients” with columns for patient_id, name, age, gender, diagnosis, medication, medication_start_date, and medication_end_date. The INSERT statements add four patient records to the table, each with a name, age, gender, diagnosis, medication, medication start date, and medication end date. This is just an example, and the table structure and data can be customized to suit your specific healthcare application.

Understanding the Continuity of Care Document (CCD) in Healthcare

Stephen Fitzmeyer, MD

In healthcare, it is crucial to have an accurate and complete medical history for patients in order to provide the best possible care. The Continuity of Care Document (CCD) is a standard format for summarizing a patient’s medical history and care plan. It contains a concise summary of the patient’s health status, including medical conditions, medications, allergies, and other relevant information. In this article, we will explore the CCD in more detail, including its structure and use cases.

The CCD is based on the HL7 Clinical Document Architecture (CDA) standard, which provides a framework for structuring clinical documents. The CCD is designed to be a concise, easy-to-read summary of a patient’s health status that can be shared among healthcare providers. It includes information about the patient’s medical conditions, medications, allergies, immunizations, procedures, and laboratory results. The CCD also includes information about the patient’s care plan, such as goals, instructions, and recommended follow-up visits.

The CCD can be used in a variety of settings to improve care coordination and continuity. For example, a patient might be referred from a primary care physician to a specialist. By sharing the CCD, the specialist can quickly get up to speed on the patient’s medical history and current care plan, which can improve the quality of care and reduce the risk of medical errors. The CCD can also be used in emergency situations, where a patient might not be able to provide a complete medical history.

Here are some examples of how the CCD can be used:

Referrals: When a patient is referred from one healthcare provider to another, the referring provider can send a CCD to the receiving provider. This ensures that the receiving provider has all the necessary information to provide appropriate care.

Transitions of Care: When a patient is discharged from a hospital or other healthcare facility, a CCD can be sent to the patient’s primary care provider. This ensures that the primary care provider has all the necessary information to manage the patient’s care after discharge.

Emergency Situations: When a patient is brought to an emergency department, a CCD can be used to provide important medical information to the emergency department staff. This can help ensure that the patient receives appropriate care and treatment.

Patient Portals: Some healthcare organizations offer patient portals that allow patients to access their medical records online. The CCD can be used to provide a summary of the patient’s medical history and care plan in a format that is easy for patients to understand.

In conclusion, the CCD is a standard format for summarizing a patient’s medical history and care plan. It includes information about the patient’s medical conditions, medications, allergies, immunizations, procedures, and laboratory results. The CCD can be used in a variety of settings to improve care coordination and continuity, including referrals, transitions of care, emergency situations, and patient portals. By using the CCD, healthcare providers can improve the quality of care and reduce the risk of medical errors.

HL7: The Technicalities and Use Cases in Healthcare

By Stephen Fitzmeyer, MD

HL7 (Health Level Seven) is a widely adopted standard in healthcare for exchanging information between various healthcare applications, such as electronic health record systems, laboratory information systems, and radiology information systems. The standard defines a set of rules and formats for the exchange of clinical and administrative data. In this article, we will explore the technicalities of HL7 and provide examples of how it can be used in healthcare.

HL7 is composed of several messages, each containing one or more segments. Segments are made up of fields, and fields can contain subfields. Each segment contains information about a specific aspect of a patient’s clinical or administrative data. The most common message types in HL7 are the ADT (Admit, Discharge, Transfer), ORM (Order), and ORU (Observation Result) messages.

For example, an ADT message might contain information about a patient’s admission to the hospital, including their demographic information, admission date and time, and the admitting physician’s name. An ORM message might contain information about a laboratory test order, including the test name, patient’s name, and date and time the test was ordered. An ORU message might contain information about the results of a laboratory test, including the test name, patient’s name, and the actual test results.

HL7 can be used in a variety of ways to exchange data between healthcare applications. For example, a laboratory information system might send an ORU message to an electronic health record system when the results of a laboratory test are ready. The electronic health record system can then display the results to the provider, allowing them to make informed decisions about the patient’s care.

Another example is the use of HL7 in medical billing. A hospital’s billing system might receive ADT messages from an electronic health record system when a patient is admitted, transferred, or discharged. The billing system can then use this information to generate a claim for payment from the patient’s insurance company.

In addition to facilitating data exchange between healthcare applications, HL7 can also be used to integrate clinical decision support systems (CDSS) into electronic health record systems. CDSS systems can analyze patient data and provide recommendations to providers, such as suggesting alternative medications or highlighting potential drug interactions. By integrating CDSS systems with electronic health record systems using HL7, providers can make more informed decisions and improve patient outcomes.

In conclusion, HL7 is a widely adopted standard in healthcare for exchanging clinical and administrative data between various healthcare applications. HL7 messages contain segments and fields that contain patient data, and there are several message types used for different purposes. HL7 can be used to exchange data between applications, integrate CDSS systems into electronic health record systems, and facilitate medical billing. By adopting HL7, healthcare providers can improve patient outcomes and streamline administrative processes.

The next step is to choose a programming language for coding the PHR. There are many programming languages to choose from, including Java, Python, Ruby, and PHP. The choice of programming language will depend on the developer’s expertise, the features required, and the platform on which the PHR will be deployed.

Step 3: Design the user interface

The user interface (UI) is the part of the PHR that patients will interact with. The UI should be intuitive and easy to use. It should allow patients to input and view their health information, as well as update and share it with healthcare providers. The design of the UI should be based on best practices for user experience (UX) and accessibility.

Step 4: Develop the back-end

The back-end of the PHR is the part of the application that handles the storage and retrieval of data. The back-end should be designed to ensure the security and confidentiality of patient health information. It should also be scalable and efficient, to handle large volumes of data and support future expansion.

Step 5: Integrate with other systems

PHRs need to integrate with other healthcare systems, such as electronic health records (EHRs), health information exchanges (HIEs), and patient portals. Integration with these systems will allow patients to access their health information from different sources, and share it with healthcare providers as needed.

Step 6: Test and deploy

Before deploying the PHR, it is essential to test it thoroughly to ensure that it works as expected and meets the needs of patients and healthcare providers. Testing should include functionality testing, performance testing, security testing, and user acceptance testing. Once testing is complete, the PHR can be deployed on a secure platform, such as a cloud-based server or a local server.

Conclusion

Coding a PHR requires careful planning and attention to detail. By following the steps outlined in this article, developers can create a PHR that is secure, scalable, and user-friendly. A well-designed PHR can empower patients to take control of their health information, improve healthcare outcomes, and support the delivery of personalized and coordinated healthcare services.
