Introduction and background

In modern healthcare systems, Electronic Health Records (EHRs) and Health Information Exchange (HIE) are critical components. The Health Information Technology for Economic and Clinical Health (HITECH) Act of 2009 boosted hospital use of Electronic Health Records (EHR) [1]. EHRs contain multifaceted, diverse, multimodal, infrequent data and time series, such as laboratory test results, doctor's written notes, patient prescriptions, demographic details, diagnoses, epidemiological studies, behavioral data, etc. Clinical responsibilities based on this enormous data set can range from acute care to long-range planning. Also, information from electronic health records can aid in therapy selection, identifying patient similarities, incorporating genetic data for customized treatment, forecasting hospital length of stay (LoS), and predicting patients' readmission risks [2].

The HIE is an essential element of the Health Information Technology (HIT) architecture designed to ease the electronic transfer of patient information between medical institutions throughout the treatment process [3]. HIE can increase the effectiveness, safety, and quality of healthcare services. Despite their potential benefits, EHRs and HIE are accompanied by technological limitations, monetary constraints, a lack of compatibility, and security and privacy challenges, which are the most frequently mentioned hurdles [4]. In addition, there are a variety of healthcare stakeholders who might be both vendors and consumers of health information. Coordination among all parties involved might be complex due to legal, security, confidentiality, and operational concerns [5,6]. Healthcare patients are essential stakeholders since their agreement is required to share their personal medical information. Patients' views about revealing confidential medical data may impact the design of forthcoming health information systems [5,6].

Artificial intelligence (AI) methods have been widely utilized in numerous domains of the ‎healthcare field, encompassing personalized treatment plans, offering evidence-based ‎recommendations derived from analyses of patient data, error identification, and accurate ‎disease diagnosis [7]. Additionally, AI can play a pivotal role in EHR systems, smoothing the path for exchange ‎and synergy of health data in diverse healthcare environments, which is vital for integrated ‎care coordination. However, given the AI's limitations, exercising utmost care and caution ‎becomes vital when embracing an AI chatbot in this context [8]. Moreover, it is essential to identify and use a suitable tool that can effectively help ‎standardize the evaluation process for assessing the accuracy and reliability of health ‎information generated by AI-based models. Ensuring the responsible and cautious ‎implementation of AI technologies in healthcare systems is essential, ultimately delivering ‎benefits to patients and healthcare providers alike [9].

Bibliometric analysis is a computer-based method utilized in scientific research to quantitatively evaluate publications within a specific field or subject matter [10-12]. This technique not only identifies key authors and core research but also elucidates the connections between them through the statistical analysis of books, journals, and other publications. Essential for tracking an author's output and influence, bibliometric analysis is also instrumental in determining journal impact factors and visualizing publication linkages to better understand scholarly networks [13-15]. Serving multiple purposes, it pinpoints seminal works and core literature, monitors the evolution of research trends, and assesses the impact of individual researchers and institutions. Widely applied in science and technology studies, library and information science, and research policy-making, bibliometric analysis supports strategic planning and funding decisions. The methodology encompasses data collection from bibliographic databases like Web of Science, Scopus, or Google Scholar, followed by data cleaning to eradicate duplicates and rectify inaccuracies, and comprehensive data analysis [16,17]. This analysis may include mapping scientific fields, performing citation analysis to trace influence and knowledge flows, and conducting network analysis to explore relationships among authors, institutions, and countries. Techniques such as co-citation and co-authorship analysis are frequently employed to identify research clusters and collaborative patterns [18]. Overall, bibliometric methods provide an empirical foundation for comprehending the dynamics of scientific research, offering crucial insights for scholars, policymakers, and librarians alike, thereby enabling stakeholders to effectively and strategically navigate the vast landscapes of scientific output [19-22].

RStudio is a software program that provides an integrated environment for working with R, a programming language used for statistical computing and graphics. RStudio comes in two flavors: RStudio Desktop, a standard desktop application, and RStudio Server, which runs on a remote server and can be accessed via a web-based browser [23]. Bibliometrix is a free and open-source application for visually representing scientific literature. It was written in R to use with other analytical and graphical applications [24]. As a result, Bibliometrix has become extremely user-friendly, even for individuals with no programming experience. Bibliometrix contains routines for importing bibliographic information from SCOPUS, Clarivate Analytics' Web of Science, PubMed, Digital Science Dimensions, as well as Cochrane databases, performing bibliometric analysis and generating data matrices for co-citation, association, collaborative research analysis, and co-word analysis. Users can input bibliographic data in a wide range of formats, including BibTeX, RIS, and EndNote XML, and conduct various studies, such as network analysis, bibliometric analysis, and keyword mining. The application provides multiple visualization options, such as network schematics, word clouds, and heat maps, to help users better understand their data and communicate the results they explore [23,25]. It is an indispensable tool for scholars, librarians, and other specialists who work with bibliographic information because it helps them to obtain different perspectives and make well-informed decisions based on their findings.

VOSviewer, a versatile and user-friendly software tool, plays a pivotal role in visualizing and analyzing bibliometric data, facilitating a deeper understanding of scholarly landscapes. Leveraging innovative algorithms, VOSviewer enables researchers to construct and visualize co-authorship networks, co-citation networks, and keyword co-occurrence networks with remarkable clarity and precision. Its intuitive interface empowers users to explore complex relationships among documents, authors, and keywords, thereby uncovering hidden patterns and trends within vast bibliographic databases [26,27]. Moreover, VOSviewer offers customizable visualization options, allowing users to tailor visual representations to their specific research objectives. With its robust features and user-centric design, VOSviewer continues to serve as an indispensable tool for bibliometric analysis, contributing to the advancement of scientific inquiry across diverse disciplines.

The study's research objectives in the field of Electronic Health Records (EHR) and Health Information Exchange (HIE) encompass a comprehensive analysis spanning from 2005 to 2024. The goals include assessing trends in scholarly output to identify and evaluate the publication dynamics over the years, including periods of growth and decline. It also aims to identify key publications and journals by analyzing the volume of documents they have published, which will highlight the most prolific sources in the field. Another significant objective is to evaluate the impact of individual researchers by examining the extent of their contributions and their association with specific research topics. This study will also map the research landscape through keyword co-occurrence analysis, which will uncover central themes, technological focuses, and socio-economic considerations within the literature. Additionally, it intends to analyze international collaboration by studying the network of co-authorship globally to understand collaboration patterns and the roles different countries play. Lastly, the research will explore interdisciplinary connections to pinpoint potential areas for innovative research and development across different research areas within the field.

The scientific literature for this study was systematically sourced from the Scopus database as of April 7, 2024.
