What is Interoperability?
We live in an interconnected world where businesses and organizations rely on complex networks of systems and devices to support their operations. Certainly, today, with cell phones, the Internet, and all the gadgets that we use, you might say people are more connected with each other than ever. In this 
In an increasingly connected world, information flows between us and the organizations and companies we deal with every day. This is also true for the computers and other electronic gadgets that we use.
Interoperability is crucial in today's connected world, where many systems, devices, and applications support various processes and activities. Interoperable systems, devices, and applications enable organizations to streamline operations, increase efficiency, and provide better customer service.
The prevalence of interoperability has increased in recent years due to the growth of digital technologies and the increasing demand for seamless and efficient data exchange. The development of standardized protocols and APIs, such as HL7, FHIR, and REST, has also helped to promote interoperability across different systems, devices, and applications.
Interoperability is the ability of different information technology systems, devices, or software applications to seamlessly communicate, exchange, and use data, ensuring information can be easily shared between systems regardless of their technology, architecture, or vendor.
In summary, interoperability is essential to today's interconnected world, as it enables organizations to communicate and exchange data effectively and efficiently. It significantly benefits organizations, including improved data sharing and collaboration, enhanced data quality, increased efficiency, lower costs, improved user experience, and better security and privacy. To maximize the benefits of interoperability, organizations must focus on creating a culture of collaboration and data sharing and investing in technology solutions that enable seamless data exchange between different systems and devices.
Types of Interoperability
Systems not only need to have the ability to exchange information, but they must also be able to interpret and present the information to the recipient in an intelligent way. Each component, as defined by the HIMSS, demonstrates the types of exchange that different organizations may participate in, as well as data sharing that may occur concurrently within an individual setting. This three-tiered model includes:
Foundational Interoperability
This is the initial tier of data sharing between disparate systems. It ensures that one software system has the ability to connect to a separate software system to share and receive data between the two. It does not take into account the ability of the receiving system to be able to interpret the data without technology.
Structural Interoperability
This intermediate tier defines the structure or format of data to be exchanged. Healthcare data should be exchanged standard or uniformly from one system to another. This is also known as syntactic or technical interoperability, and it ensures that sharing can be interpreted at the data field level. The HIMMS states that “the clinical or operational purpose and meaning of the data must be preserved and unaltered.”
Semantic Interoperability
This highest tier ensures the ability of two or more systems to share, interpret and use the information that is exchanged. Semantic interoperability utilizes both the structuring and codification of the data (including standard vocabulary) in order to support the electronic exchange of patient data and information. In healthcare, semantic interoperability is vital to potentially eliminate the technology and terminology gaps that currently exist between the numerous software systems and data sources.
Interoperability in Healthcare
When applied to healthcare, Interoperability is the ability of different healthcare information technology systems and software applications to communicate, seamlessly exchange, and use electronic health data to enhance health outcomes for individuals, populations, and healthcare systems. In simpler terms, interoperability allows different healthcare systems to work together seamlessly and share information meaningfully to avoid duplication of tests, reduce medical errors, and improve care coordination. The underlying technology, architecture, or vendor used to exchange data is not material
From a technology perspective, what makes it happen includes data exchange schemas and standards that permit data to be shared across clinicians, labs, hospitals, pharmacies, and patients regardless of the application or application vendor.
Imagine that a doctor's office uses a different computer system than the hospital where a patient had a recent procedure. Without interoperability, you would not have access to important information about your patient's procedure and could make decisions based on incomplete information.
Current State of Interoperability in Healthcare
As of 2023, significant strides have been made in improving interoperability among healthcare systems, driven by technological advancements, regulatory mandates, and industry-wide initiatives. However, challenges such as data silos, inconsistent data standards, and varying levels of technology adoption continue to hinder full-scale interoperability.
In recent years, the 21st Century Cures Act, enacted in 2016 and further enforced through the Office of the National Coordinator for Health Information Technology (ONC) has played a critical role in advancing interoperability. The Act mandates that healthcare providers and payers adopt standardized APIs (Application Programming Interfaces) for seamless data exchange, prohibiting information-blocking practices. This has led to greater adoption of Fast Healthcare Interoperability Resources (FHIR) standards, enabling more efficient and secure data sharing across different systems. According to a 2022 ONC report, the adoption of FHIR-based APIs has increased significantly, with nearly 70% of hospitals in the United States now using these standards for health information exchange.
Despite these advancements, achieving true interoperability remains an ongoing challenge. The healthcare ecosystem is vast and complex, encompassing many stakeholders including hospitals, clinics, insurance providers, and patients. The lack of uniform data standards and the prevalence of legacy systems further complicate the integration efforts. Nevertheless, industry collaborations, such as the Common Well Health Alliance and the Care Quality Interoperability Framework, foster greater cooperation and set the stage for a more connected and interoperable healthcare system. As we move forward, continued focus on standardization, technological innovation, and regulatory compliance will be crucial in overcoming these barriers and realizing the full potential of interoperability in healthcare.

Looking Ahead
The ever-changing and technologically advancing field of medicine poses specific challenges to the role of interoperability for small practices and medical providers. Regardless of the size of the practice, federal and state regulations apply to all. This push to share data is close to reaching its goal, but there are bumps in the road for some providers. Even though the technical means exist, not all providers use interoperable technology components. A large part of this is due to the lack of resources that smaller and single practices have. However, many of these providers are realizing that interoperability is a crucial strategy for maintaining independence.
