Healthcare delivery relies heavily on sophisticated digital systems to manage, exchange, and protect patient information. As technology advances, understanding how these systems communicate becomes essential for healthcare professionals, administrators, and IT specialists alike. This article explores the critical roles played by Application Programming Interfaces (APIs) and HL7 standards in creating seamless data flow across healthcare platforms, ultimately improving patient outcomes and operational efficiency.
In a healthcare environment where timely and accurate information exchange is vital, the deployment of robust data standards and interfaces is not just a technical concern but a fundamental component of quality care. Whether integrating electronic health records (EHRs), enabling remote patient monitoring, or facilitating inter-provider communication, APIs and HL7 protocols form the backbone of modern health IT infrastructure. They help bridge diverse applications, ensuring vital health data is accessible, secure, and usable wherever and whenever needed.
What Does API Stand for in Healthcare?
A common question among healthcare professionals is, “What does API stand for in healthcare?” The term API, or Application Programming Interface, refers to a set of rules and protocols that enable different software applications to communicate with each other. According to the Journal of AHIMA, an API effectively acts as a digital bridge—allowing disparate systems to share data regardless of their underlying design or architecture.
APIs are ubiquitous in modern technology, powering everything from social media integrations to financial transactions. In healthcare, APIs facilitate the real-time sharing of information, such as updating a patient’s electronic health record or retrieving lab results from a laboratory system. This capability significantly enhances workflow efficiency, reduces manual data entry errors, and promotes interoperability among various healthcare platforms.
ADSC employs API technology in our MedicsPremiere interface, which sources data from multiple external systems. Instead of relying solely on traditional electronic data interchange (EDI), APIs enable direct data processing, simplifying integration and improving response times. Security measures like static gateway keys and HMAC signatures safeguard data exchanges, while features like IP and device ID filtering help control access. This approach ensures that healthcare providers can access comprehensive patient data swiftly and securely, streamlining clinical decision-making.
What Is HL7 in Healthcare?
Many of our clients inquire about HL7 in healthcare systems. HL7, or Health Level Seven International, is a globally recognized organization dedicated to developing standards that support the exchange, integration, sharing, and retrieval of electronic health information. Established in 1987 and accredited by the American National Standards Institute (ANSI), HL7 focuses on creating frameworks that improve healthcare interoperability.
The organization’s name derives from the seven layers of the OSI (Open Systems Interconnection) model, with “Level Seven” representing the application layer responsible for direct interaction with software applications. HL7 standards provide a uniform language for healthcare data, enabling diverse systems—such as hospital information systems, laboratory systems, and pharmacy management platforms—to communicate seamlessly.
The overarching goal of HL7 is to foster a healthcare ecosystem where data can flow effortlessly across boundaries. This is critical in scenarios like transferring patient information from a primary care provider to a specialist in another state, or enabling patients to access their health records through mobile apps. For example, an HL7 interface standardizes how patient details are transmitted between different electronic health record platforms, making sure all parties see consistent, accurate data.

What Is the Difference Between HL7 and FHIR?
Understanding the distinction between HL7 and FHIR (Fast Healthcare Interoperability Resources) is crucial for grasping how healthcare data exchange continues to evolve. FHIR, pronounced “fire,” is a modern, web-based standard developed by HL7 that leverages APIs to facilitate the exchange of healthcare information. Unlike traditional HL7 messages, which often involve complex and rigid formats, FHIR uses simple, standardized resources that can be easily accessed and manipulated via RESTful APIs.
FHIR was designed to fulfill the promise of APIs in healthcare, enabling real-time, secure data sharing between diverse EHR systems. Its flexible structure supports mobile applications, cloud-based services, and other innovative solutions, making healthcare data more accessible to both providers and patients. For instance, a patient might use a smartphone app to view their latest lab results or medication list, thanks to FHIR-enabled data exchange.
By adopting FHIR alongside HL7 standards, healthcare organizations can achieve a higher level of interoperability, ensuring that data flows smoothly across systems and platforms.

Work With a Healthcare Software Provider That Is Well Versed in API and HL7 Technical Requirements
Gaining a clear understanding of what APIs and HL7 standards entail empowers healthcare providers to leverage these tools more effectively. Partnering with a software provider experienced in these technologies ensures that your organization can implement and maintain interoperable systems efficiently. It’s essential to work with experts who comprehend the technical nuances, security protocols, and compliance requirements involved in healthcare data exchange.
Integrating advanced API and HL7 capabilities can significantly enhance operational workflows, improve patient care, and reduce costs. For example, APIs can enable the connection of a hospital’s EHR with third-party applications, such as telehealth platforms or AI-powered diagnostic tools. Similarly, HL7 standards streamline the transfer of clinical data between different healthcare entities, fostering continuity of care.
