As we move into an increasingly digital age, healthcare organizations have changed many things about their practices. From new treatment options to the explosion of health data available thanks to smart devices, your doctor’s visit may look a little different today when compared to 10 years ago. But this overlooks one of the biggest changes yet – the adoption of electronic health records.
Shifting to electronic health record systems has shown many benefits! By digitizing patient information, providers can track data over time, identify trends, monitor patients, and more. If done correctly, the migration to an electronic health records system can improve both patient data protection and process efficiency.
With the potential to make patient care seamless, the goal of electronic health information is to provide easier access to care and to better coordinate care delivery for a patient across multiple providers.
Ideally, patient health information can follow a patient throughout their care: from their annual physical to displaying previous imaging when a patient is in the hospital. This enables a patient’s care team, regardless of clinic or location, to provide care that is informed and comprehensive.
Making the transition from paper records to digital health systems can initially seem like a daunting task. There are many facets of making this transition to take into account:
- Data Migration: The time and effort required to move existing data to the new digital system. Make sure you’re allocating sufficient time and resources for data entry, verification, and quality control for the amount of data your practice needs to enter.
- Training: Shifting from a paper system to a digital system can require additional, comprehensive training for clinicians and staff alike. Spend time both exploring the new hospital information system and ensuring that your team understands the importance of patient safety and how it can relate to HIPAA.
- Cost Consideration: In addition to upfront costs, there are also maintenance, upgrades, and future data security measures to take into account when planning a long-term budget for this.
Arguably, one of the most important factors to consider in order to streamline your practice and delivery of care is interoperability and maintaining data exchange standards in telehealth services.
What is Health Information Exchange and Data Sharing (Interoperability)?
Before we can delve into why interoperability and data exchange standards in telehealth software are so important to healthcare providers, we first have to define health information exchange and interoperability.
Health information exchange (HIE) refers to the electronic sharing of patient health information across different healthcare organizations and systems. It enables the secure exchange of health information, such as medical records, lab results, medication history, and imaging reports, among healthcare providers, hospitals, clinics, laboratories, and other authorized entities in the health system involved in a patient’s care.
Health information exchange allows healthcare professionals to access relevant patient information at the point of care, regardless of where the patient’s health information originated. This seamless exchange of information facilitates coordinated and informed decision-making, improves care quality, reduces medical errors, and enhances patient outcomes.
HIE systems typically utilize standardized formats and protocols to ensure compatibility and secure transmission of data.
Data sharing, or interoperability, on the other hand, refers to the ability of different health systems, applications, or devices to exchange and use health information technology effectively. It involves the integration and compatibility of various electronic health records (EHR) systems, telehealth platforms, wearable devices, and other health technologies.
Interoperability in healthcare enables the seamless flow of data across disparate systems, ensuring that healthcare providers have access to comprehensive patient information when and where they need it. It allows for the integration of data from different sources, such as hospitals, pharmacies, laboratories, and imaging centers, eliminating information silos and promoting holistic patient care.
Interoperability can be achieved through the use of standardized data formats, such as Fast Healthcare Interoperability Resources from HL7 International (HL7 FHIR) or US Core Data for Interoperability (USCDI), which facilitate the exchange of structured data. Additionally, interoperability standards ensure data privacy and security, establishing protocols for authentication, authorization, and encryption to protect patient information during transmission and storage.
The Current Standards in Interoperability for Healthcare Technology
In the realm of healthcare technology, several standards have emerged to facilitate interoperability and seamless health information exchange between different systems. Here are some of the key standards used in interoperability for healthcare technology:
- Health Level Seven International (HL7): HL7 is one of the most widely adopted standards for interoperability in healthcare. It provides a framework and a set of messaging standards for the exchange, integration, sharing, and retrieval of electronic health information. HL7 encompasses various messaging standards which define message structures, data types, and communication protocols.
- Fast Healthcare Interoperability Resources (FHIR): FHIR is a modern and rapidly growing interoperability standard developed by HL7. It uses a web-based API to enable the exchange of health information in a fast, flexible, and developer-friendly manner. FHIR resources are granular data elements that can represent clinical data, administrative information, and other healthcare-related content. FHIR is designed to be easily implementable and supports both human-readable and machine-processable data formats.
- Digital Imaging and Communications in Medicine (DICOM): DICOM is standard for the exchange, storage, and transmission of medical images and related information. It ensures compatibility and interoperability between different imaging devices, Picture Archiving and Communication Systems (PACS), and other healthcare systems. DICOM allows for the seamless sharing of medical images and associated data, enabling clinicians to view, analyze, and exchange diagnostic images across various platforms and healthcare settings.
- International Classification of Diseases (ICD) and Systematized Nomenclature of Medicine – Clinical Terms (SNOWMED CT): ICD is a standard classification system for diseases, injuries, and related health conditions. It provides a standardized way to categorize and code diagnoses and procedures, enabling consistent and interoperable communication of clinical information. SNOWMED CT is a comprehensive clinical terminology that provides standardized codes for clinical concepts, facilitating the accurate representation and exchange of clinical health information.
- Consolidated CDA (C-CDA): Another standard developed by HL7 and is mandated for use in the United States by the Centers for Medicare and Medicaid Services (CMS). It defines the structure and semantics of clinical documents, such as discharge summaries, progress notes, and clinical summaries. CCDA enables the exchange of structured patient health information in a format that is both human-readable and machine-readable.
- Integrating the Healthcare Enterprise (IHE): IHE is an initiative that promotes the use of existing standards to achieve interoperability in healthcare. IHE develops profiles that define specific integration capabilities and workflows for different healthcare domains, such as radiology, cardiology, and laboratory findings. These profiles specify how standards like HL7, FHIR, and DICOM can be implemented to solve specific interoperability challenges and enable seamless information exchange between systems.
It’s important to note that these standards continue to evolve and be updated as technology and healthcare practices advance. Additionally, regional variations and specific healthcare domains may have their own additional standards or profiles. Staying informed about the latest standards and ensuring compatibility with the required standards is crucial for successful interoperability in healthcare technologies.
The Four Levels of Interoperability
The four levels of interoperability, often referred to as the Interoperability Maturity Model, provide a framework for understanding the progression and complexity of interoperability. Each level represents a stage of interoperability, building upon the previous level to achieve more advanced and comprehensive health information exchange capabilities. Let’s explore each level in detail:
Foundational Level
At the foundational level, interoperability focuses on the ability of different systems to exchange data. It establishes the basic infrastructure and technical framework required for health information exchange. This level ensures that systems can send and receive information but does not involve any interpretation or understanding of the data being exchanged. Common protocols, messaging standards, and transport mechanisms enable health information exchange, such as using standard file formats or basic messaging protocols.
Structural Level
Structural interoperability involves the agreement on the format and structure of the exchanged data. It ensures that data can be interpreted accurately by receiving systems. This level defines the syntax and organization of data elements, including the use of standardized data models, data dictionaries, and coding systems. For example, using standardized data models like HL7 or FHIR to represent clinical information ensures that the data can be understood and processed consistently across systems.
Semantic Level
Semantic interoperability goes beyond the structure and format of data to achieve a common understanding of the meaning and context of the information being exchanged. It involves the use of standardized terminologies, ontologies, and clinical vocabularies to ensure that data elements have agreed-upon definitions and can be interpreted correctly. This level enables systems to share and interpret data in a way that supports clinical decision-making and meaningful exchange of patient information.
Organizational Level
Organizational interoperability encompasses the highest level of interoperability. It focuses on the coordination and collaboration between different healthcare organizations and stakeholders involved in healthcare delivery. This level involves the alignment of policies, workflows, governance structures, and business processes to support seamless health information exchange and care coordination across organizational boundaries. Organizational interoperability requires agreements, protocols, and shared standards to ensure effective data sharing, care transitions, and coordinated patient care.
It is important to note that achieving higher levels of interoperability requires an incremental approach, starting with foundational interoperability and progressively advancing toward organizational interoperability. Each level builds upon the previous one, enabling more comprehensive and meaningful data exchange and ultimately improving patient care, care coordination, and healthcare outcomes.
