Health Information Exchange: Understanding the Policy Landscape and Future of Data Interoperability

Abstract

Objectives: To review recent literature on health information exchange (HIE), focusing on the policy approach of five case study nations: the United States of America, the United Kingdom, Germany, Israel, and Portugal, as well as synthesize lessons learned across countries and provide recommendations for future research. Methods: A narrative review of each nation’s HIE policy frameworks, current state, and future HIE strategy. Results: Key themes that emerged include the importance of both central decision-making as well as local innovation, the multiple and complex challenges of broad HIE adoption, and the varying role of HIE across different national health system structures. Conclusion: HIE is an increasingly important capability and policy priority as electronic health record (EHR) adoption becomes more common and care delivery is increasingly digitized. While all five case study nations have adopted some level of HIE, there are significant differences across their level of data sharing infrastructure and maturity, and each nation took a different policy approach. While identifying generalizable strategies across disparate international systems is challenging, there are several common themes across successful HIE policy frameworks, such as the importance of central government prioritization of data sharing. Finally, we make several recommendations for future research to expand the breadth and depth of the literature on HIE and guide future decision-making by policymakers and practitioners.

Digital Anti-Aging Healthcare: An Overview of the Applications of Digital Technologies in Diet Management

“…The healthcare industry has witnessed the development of a multitude of personal health applications and remote monitoring devices to directly address the challenges related to healthcare facilities and the availability of service delivery, enabling on-demand and automated vital signs monitoring, medication tracking, and personalized health recommendations that are fundamental for effective and efficient self-management of potential diseases [ 72 , 73 ]. The interoperability of healthcare data and secure data transmission through Health Information Exchange (HIE) platforms has facilitated data sharing, thus enabling fast and reliable data analysis from a distance, reducing redundancies in data, and enhancing care coordination [ 74 ]. However, digital technologies have transformed healthcare delivery modes by expanding the landscape and improving outcomes.…”

Informatics for One Health

“…In the survey paper of the Health Information Exchange (HIE) section, Holmgren et al presented the policy of five different countries (USA, UK, Germany, Israel and Portugal) in terms of HIE [24]. For each country, the authors reported the existing frameworks and the remaining considerations to be considered.…”

A review of the challenges and opportunities in implementing health informatics in rural healthcare settings

“…Interoperability Issues Achieving interoperability between different health IT systems is crucial for seamless data exchange and continuity of care , Aturamu, Thompson & Akintuyi, 2021. However, rural healthcare providers may use disparate systems that are not interoperable, leading to data silos and inefficiencies in information sharing between providers, hospitals, and other healthcare stakeholders (Holmgren et al, 2023). Data Security and Privacy Concerns, Rural healthcare organizations must comply with strict regulations regarding the security and privacy of patient health information, such as HIPAA (Health Insurance Portability and Accountability Act).…”
