Technology is now an inseparable part of our lives, and that holds true for businesses as well. In fact, many businesses require multiple technological devices to work harmoniously with each other for them to function effectively.
Making these separate technological devices work seamlessly with each other is broadly what interoperability is. As the healthcare industry quickly adapts to newer technologies to increase efficiency and offer better patient outcomes, interoperability of healthcare technology has become essential.
So much so that HIPAA supports interoperability, and that interoperability in healthcare as an industry is projected to grow at a CAGR of 11.31%, from $4.07 billion in 2023 to $6.96 billion by 2028.
What is Interoperability in Healthcare?
Interoperability in healthcare is the capability of various healthcare systems, software, and devices to seamlessly share and utilize patient information. This involves the smooth exchange of critical data like medical records, test results, and treatment plans among different healthcare entities, such as hospitals, clinics, pharmacies, and laboratories.
When these systems work together effectively, healthcare providers gain access to a complete and up-to-date view of a patient’s health. This comprehensive access helps them make better-informed decisions and ultimately leads to improved patient outcomes.
To achieve interoperability, there are four key levels to consider:
- Foundational Level: This is about ensuring that the basic infrastructure for communication and data security is in place. It’s like setting up a secure network for data exchange.
- Structural Level: This involves organizing and formatting the data so that it can be easily shared and understood across different systems. Think of it as putting data into a standard format that everyone can read.
- Semantic Level: Here, standardized data elements and coding systems are used to ensure that the data has a consistent meaning across different platforms. This level ensures that everyone interprets the data the same way.
- Organizational Level: This covers the legal, social, and administrative aspects necessary for the secure and effective use of shared data. It deals with policies and practices that support seamless data exchange within and between organizations.
Effective interoperability not only enhances the ability of healthcare providers to access complete patient information but also supports researchers and public health officials in tracking and responding to health trends. For patients, it means having easier access to their own health data, while for clinicians, it provides a fuller picture of patient history, leading to better care. Despite the challenges involved, the benefits of interoperability in improving healthcare quality and system efficiency make it a crucial goal.
What Are the Four Levels of Interoperability in Healthcare?
The Healthcare Information and Management Systems Society (HIMSS) identifies four levels of healthcare interoperability.

This level ensures data is transmitted in a consistent format, allowing systems to recognize and receive the information. It addresses the technical compatibility needed to send and receive data without loss or corruption, essentially “opening the pipes” for data flow. Foundational interoperability is crucial as it lays the groundwork for more advanced interoperability, which will require additional technological and process innovations.
Structural Interoperability
The next level, structural interoperability, ensures that data exchanged between systems follows a standardized format and structure. It defines how data elements are organized and how they relate to each other, allowing different systems to accurately interpret and process the data. This level uses standards like HL7 FHIR (Fast Healthcare Interoperability Resources), DICOM (Digital Imaging and Communications in Medicine), and CDA (Clinical Document Architecture) to ensure data is formatted in a way that supports seamless integration and interpretation. Adhering to these standards improves data usability, reduces the need for manual intervention, and enables healthcare providers to identify care gaps and integrate recommendations into the patient’s longitudinal record, thus enhancing overall efficiency and quality of care.
Semantic Interoperability
Semantic interoperability, the highest level of interoperability, goes beyond basic data exchange to ensure that the meaning and context of the data are preserved. This level focuses on harmonizing the interpretation of data elements across different systems by using common terminology, codes, and definitions. It involves establishing a shared vocabulary that enables consistent data interpretation, such as ICD-10 codes for mortality statistics and SNOMED CT for clinical terminology. Achieving semantic interoperability allows for accurate machine-to-machine communication, enhances clinical decision-making, and supports advanced analytics and research. Despite its potential, the industry faces challenges with scattered systems and inconsistent terminologies, necessitating ongoing efforts to standardize and normalize data to ensure clear, actionable insights.
Cross-Enterprise Interoperability
The fourth level, organizational interoperability, focuses on aligning processes, policies, and governance structures to enable seamless data exchange and collaboration across healthcare entities. It involves establishing agreements, protocols, and workflows that govern data sharing among providers, payers, and public health agencies. This level requires clear leadership, effective communication, and robust governance frameworks to address legal, privacy, and security issues while promoting data sharing for better care coordination and population health management. Organizational interoperability integrates technical and regulatory aspects to ensure comprehensive data governance and privacy, exemplified by frameworks like the Trusted Exchange Framework and Common Agreement from the US Office of the National Coordinator for Health Information Technology.
