The Quest for a Sustainable, Patient-Centric Healthcare System

In today's rapidly evolving healthcare landscape, the push for a sustainable and patient-centered system hinges on the ability to integrate supply chains using cutting-edge information technologies. Yet, the challenge of achieving interoperability between various healthcare devices and systems remains a daunting obstacle. Recent research underscores a crucial need for systematic reviews to address this complex and multifaceted domain.

The Research Gap: A Call for Comprehensive Understanding

Alarmingly, there is a distinct lack of studies that have outlined the structure of healthcare interoperability or developed a robust, high-order taxonomy framed within the context of supply or value chains. This groundbreaking study set out to fill that void, aiming to clarify the intricate knowledge landscape of healthcare interoperability while identifying trending themes and critical issues.

Methodology: A Dual Approach to Discovery

Employing a combination of quantitative and qualitative methodologies, this research was meticulously guided by the PRISMA framework. An extensive review of six leading databases—Scopus, Web of Science, IEEE Xplore, Embase, Cochrane, and PubMed—was conducted, focusing on journal articles and gray literature from 2011 onwards. Through a careful screening process using stringent eligibility criteria, 370 articles were identified for quantitative analysis.

Revealing Insights: Clusters of Knowledge

The bibliometric analysis uncovered two primary clusters of knowledge. The first cluster, emphasizing terms like interoperability, electronic health records, and eHealth, showcased significant centralities, marking its importance in the discourse. Meanwhile, the second cluster revealed emerging concepts such as IoT, blockchain, and healthcare, indicating the innovative trajectory of the field.

Crafting a New Taxonomy: A Deeper Understanding

Factor analysis revealed that a two-factor model accounted for a remarkable 59.46% of variance, highlighting the importance of these clusters. Additionally, a qualitative review of 79 articles led to the development of a new taxonomy encompassing four higher-order facets: object (what is shared), source (mechanism of sharing), ambit (scope of application), and content (primarily involved technology). Each facet expands into a third level, offering a nuanced classification that could reshape our approach to interoperability.

A Step Towards the Future of Healthcare

This study is not just academic; it represents a vital stepping stone toward creating a more connected, efficient, and patient-centered healthcare system. By addressing the gaps in understanding healthcare interoperability, we pave the way for innovations that could radically transform patient care and operational efficiencies across the healthcare ecosystem.
