Once upon a time, a patient was in the hospital for a routine procedure. Despite the hospital having access to their electronic health record (EHR), the patient's primary care doctor was unable to access the information they needed to properly care for their patient. This is a frustratingly common problem in healthcare, and it's one that I'm passionate about solving as a healthcare informatician.
Interoperability - the ability of different healthcare systems to share and use data - is a key factor in providing better patient care. Unfortunately, there are many barriers preventing healthcare providers from achieving interoperability. In this blog post, I will break down these barriers and discuss how we can work to overcome them.
Interoperability in healthcare the ability of different information systems, devices and applications (systems) to access, exchange, integrate and cooperatively use data in a coordinated manner, within and across organizational, regional and national boundaries, to provide timely and seamless portability of information and optimize the health of individuals and populations globally. This type of exchange allows for a more efficient and seamless healthcare experience for everyone involved.
Overview of Interoperability Challenges
Interoperability in healthcare is a complex process due to a number of factors, such as disparate IT systems, varying standards and protocols, lack of data governance, and privacy and security concerns. Additionally, the current healthcare system is often siloed, which can prevent the sharing of data between different organizations.
In order to address these challenges, healthcare organizations must invest in updated IT infrastructure and adopt standards and protocols that will enable seamless data exchange. Additionally, organizations must develop policies and procedures to ensure that data is shared in a secure and compliant manner while protecting the privacy of patients. Finally, healthcare organizations must foster collaboration among stakeholders to ensure that data is shared in a timely and efficient manner.
Barriers to Interoperability
There are numerous barriers that can prevent healthcare systems from being interoperable, and these can be classified into three main categories: technical challenges, organizational challenges, and regulatory challenges.
Technical Challenges
The most obvious barrier to interoperability is the technical challenge of connecting disparate systems. This can include incompatibilities in data formats or protocols, differences in system architectures, or difficulties in exchanging data between different organizations. Additionally, there can be challenges in ensuring data security and privacy when transferring data between systems.
Organizational Challenges
Interoperability can also be hampered due to organizational barriers, such as the cost of integrating disparate systems, the lack of standardization among different organizations, and the complexity of ensuring data accuracy. Additionally, organizations may be unwilling to share data due to competitive concerns or privacy considerations.
Without a proper standardization, healthcare systems cannot easily exchange data or access information from other systems. For example, a hospital may use one data structure to represent an allergy, while a different provider may use a different data structure. As a result, data transfer between these providers is difficult and time consuming.
Regulatory Challenges
Finally, regulatory challenges can also hinder interoperability in healthcare systems. Federal regulations such as the Health Insurance Portability and Accountability Act (HIPAA) and state regulations can create additional barriers to data sharing. Furthermore, different organizations may have different policies and procedures in place to protect the privacy and security of patient data, making it difficult to share this data.
Solutions to Interoperability Challenges
Interoperability challenges are a major obstacle to sharing healthcare data across organizations and platforms. To reduce these barriers, healthcare informaticians must develop and implement solutions to enable data exchange.
Standardization of Data Structures and Protocols
The most important step towards interoperability is to develop common sets of data structures and protocols. These standards should define the structure and format of data that is exchanged between systems, as well as the protocols for transferring the data. This will ensure that all data is interoperable, making it easier for systems to share information. Additionally, by creating a standard set of data structures and protocols, healthcare informaticians can reduce the cost and complexity of developing and maintaining interoperable systems.
An example of these standards includes the Health Level Seven (HL7) protocol, which is the most widely used standard in healthcare. HL7 is a set of rules and data formats used to create messages that can be sent and received between different healthcare systems. Some other created standards are, Systematized Nomenclature of Medicine (SNOMED) International, and the Clinical Data Interchange Standards Consortium (CDISC). By using this standard, healthcare providers are able to exchange data and access information quickly and easily.
Adopting Interoperability Standards
Once common data structures and protocols have been established, healthcare organizations must adopt these standards in order to enable interoperability. This means implementing the standards in their own systems and ensuring that all data is stored using the same format and protocols. This will ensure that data can be reliably exchanged between systems, reducing the barriers to data sharing.
Investing in Interoperability Infrastructure
Interoperability infrastructure is the foundation on which healthcare organizations can build successful data sharing initiatives. Investing in the right infrastructure is critical to enabling the secure exchange of data between healthcare systems. This includes investing in hardware and software that have the necessary security and authentication measures in place to protect patient data. Additionally, healthcare organizations should invest in the necessary training and support that staff need to effectively use the technology and ensure data accuracy.
Conclusion
Interoperability in healthcare systems is like a bridge connecting patients to their doctors and their health information. But in order to make sure this bridge is strong, it needs to be built on a foundation of trust, collaboration, and open standards. We must work together to break down the barriers that prevent interoperability and build a bridge that can withstand the test of time. Now is the time for healthcare providers, policy makers, and technologists to come together and find innovative solutions that will make true interoperability a reality. Let us take the first step in creating this bridge, so that all of us can be connected to better healthcare.
