Analysis of Publications on Health Information Management Using the Science Mapping Method: A Holistic Perspective

Objective: In the age of digital transformation, there is a need for a sustainable information management vision in health. Understanding the accumulation of health information management (HIM) knowledge from the past to the present and building a new vision to meet this need reveals the importance of understanding the available scientific knowledge. With this research, it is aimed to examine the scientific documents of the last 40 years of HIM literature with a holistic approach using science mapping techniques and to guide future research. Methods: This study used a bibliometric analysis method for science mapping. Co-citation and co-occurrence document analyses were performed on 630 academic publications selected from the Web of Science core collection (WoSCC) database using the keyword “Health Information Management” and inclusion criteria. The analyses were performed using the R-based software Bibliometrix (Version 4.0; K-Synth Srl), Python (Version 3.12.1; The Python Software Foundation), and Microsoft® Excel® 2016. Results: Co-occurrence analyses revealed the themes of personal health records, clinical coding and data quality, and health information management. The HIM theme consisted of five subthemes: “electronic records”, “medical informatics”, “e-health and telemedicine”, “health education and awareness”, and “health information systems (HISs)”. As a result of the co-citation analysis, the prominent themes were technology acceptance, standardized clinical coding, the success of HISs, types of electronic records, people with HIM, health informatics used by consumers, e-health, e-mobile health technologies, and countries’ frameworks and standards for HISs. Conclusions: This comprehensive bibliometric study shows that structured information can be helpful in understanding research trends in HIM. This study identified critical issues in HIM, identified meaningful themes, and explained the topic from a holistic perspective for all health system actors and stakeholders who want to work in the field of HIM.


Introduction
The healthcare industry is rapidly evolving to meet the demands and opportunities of digital transformation [1][2][3].This evolutionary process includes some headlines such as "technology adoption" [4], "standardized clinical coding" [5], "health information system success" [6], "electronic record types" [7], "personal health information management" [8], "consumer health informatics" [9], "eHealth and eMobile health technologies" [10], "country frameworks and standards for HIS" [11], and "critical health information management".The acceptance of technology is the foundation of HIM [12].How healthcare professionals and managers approach technology is critical to the successful functioning of HIM systems [13].This acceptance process increases the effectiveness of clinical coding systems that provide a standardized language and methodology [14,15].For example, international coding systems such as the International Classification of Diseases (ICD)-10 positively impact the effectiveness and efficiency of HISs [16].
The effectiveness of HISs requires accurate data collection, analysis, and exchange processes.This means that the standardization of clinical coding has a direct impact on the success of HISs [17,18].Electronic health records and e-health technologies are essential for measuring and improving the success of systems.These platforms are used to improve the quality of patient care and ensure effective data management [19].These systems, which allow individuals to manage their own health information with effective data management, are critical to health informatics for all health system stakeholders.The ability of individuals to manage their health information more effectively enables faster and more informed health decisions [20].In this context, national and international standards and frameworks are of great importance to ensure efficiency and harmonization in HIM, integration between different topics, improvement of the overall quality of health services, increased efficiency, and cost control [11].
When it comes to HIM, many different terms and abbreviations are often encountered.Many different types of electronic records are kept during the delivery of healthcare services.Electronic medical records and electronic health records are the most important.Other types of records include personal health records, genomic point-of-care records, oncology patient records, and records for drug/pharmaceutical networks [21].Of all the record types, the ones that have undergone the most research are electronic health records (EHRs), electronic medical records (EMRs), and personal health records (PHRs) [22].Clearly defining these record types as terms is critical to establishing standards and more effectively implementing HIM [23].
These terms represent different functions, capabilities, and requirements, and there are clear differences between them.Clarity of definitions avoids confusion among all healthcare stakeholders, facilitates data exchange, and improves the overall quality of healthcare.In addition, these definitions are important for policymakers, as national and international standards and frameworks require an understanding of what these terms mean.In this context, a clear and precise definition of terms contributes to a better understanding of the different dimensions of HIM and to more effective work in this area.The text box in Appendix A defines the most important terms by compiling them from various sources.
HISs play a critical role in planning, monitoring, and evaluating health services.The effectiveness and efficient use of HISs can influence the quality of health services [24,25].HIS components such as health information technology (HIT) and electronic health records (EHRs) have significant potential to improve the efficiency and quality of healthcare [26,27].For example, Blumenthal and Tavenner (2010) [28] discussed the "meaningful use" regulation of EHRs, highlighting how this technology can add value for healthcare providers and patients.
HISs provide a critical infrastructure for the efficiency and effectiveness of healthcare services and facilitate communication and collaboration among healthcare providers, patients, and policymakers.The effective design and implementation of health information technology can improve the quality and reduce the cost of healthcare.Healthcare providers rely on HISs to organize and store patient information, plan treatment, and communicate effectively with patients.At the same time, HISs play an important role in areas such as patient safety and the prevention of medical errors [29].Several studies have examined the impact of HIT on the quality and efficiency of healthcare services.Researchers such as Chaudhry et al. (2006) [25] and Buntin et al. (2011) [24] have shown that HIT can positively affect the quality, efficiency, and cost of healthcare services.In addition to these benefits of HIM, it is important to consider the costs of installing these systems, Internet usage, data security, and training staff to use these systems.
According to the HIM literature, there is an evolution in the process of resource management and adaptation to technological change [30].Although previous reviews have traced these developments [30], it is clear that there is a need for a more comprehensive analysis of this rapidly evolving area of research, whose contribution to the health sector is increasing in parallel with the use of technology.Based on this gap, the aim of this study is to conduct a bibliometric analysis of publications on HIM using science mapping techniques.Within this framework, this study seeks to answer the following three main questions: 1. What are the most prolific authors, most cited journals and articles, and most prominent institutions, countries, and trending topics in HIM?
2. What are the most critical studies in HIM?What are the dynamics in the development of the intellectual structure of the field?
3. Can the conceptual structure of HIM be identified?It is expected that the research will make two major contributions to the literature.First, this research is considered to be the first research that examines HIM from a holistic perspective using the science mapping technique.Second, it is envisioned that this research will guide future research and fill the gap in the field by providing valuable information about the common citation analysis themes and common keyword analysis themes in the field of HIM through bibliometric and document analysis.
This paper is divided into five sections.The first section provides general information about the subject and the second section outlines the research technique.The results of the analysis, performance analysis, bibliometric analysis, and prominent types of electronic records in the field of HIM are presented in the third section.The fourth section discusses the findings and limitations of the research, and the fifth section concludes the research.

Method
The bibliometric analysis method was used for science mapping in this study.Bibliometric analysis is considered a valuable tool for gaining an in depth understanding of large amounts of data, uncovering connections between publications in the field, exploring new avenues of research, and building a solid foundation in the field [31][32][33].Especially in academic circles, such analyses are often used to evaluate article and journal performance, identify collaborative networks, and identify trends in the field [34][35][36].
This article uses the R Studio library Bibliometrix, which is free and open-source and was developed by Aria and Cuccurullo (2017) [37], as well as Python and Microsoft Excel.This software allows the direct import of bibliographic information from Scopus, Clarivate Analytics Web of Science, Dimensions, Lens.org,PubMed, or Cochrane Library to take place.It also allows one to create matrices to perform co-citation, merging, collaboration, and common word analysis.It can also provide a static picture of the field under study, with the option to divide the research period into different time periods when needed [37][38][39][40].
The research followed a scientific mapping process consisting of 5 stages, as proposed by Zupic and Čater (2015) [36].These are (1) study design, (2) data collection, (3) data analysis, (4) data visualization, and (5) interpretation [37].The study design and data collection followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) principles, as shown in Figure 1.

Data
In this study, publications on "health information management" were searched in the WoSCC database on 25 October 2023.The WoSCC contains a large collection of bibliographic lists, citation networks, and full-text articles [34][35][36].It is known as an important source for bibliometric and sub-metric analysis and is preferred by researchers due to its clear advantages.It is also a fundamental data source for bibliometric analysis and information mapping, covering a large part of the medical literature.It acts as a citation index and provides information on citations in publications.The WoSCC features, such as detailed records, data sets suitable for bibliometric analysis, and indexed prestigious publications, make it one of the most widely used sources for bibliometric analysis.The research data in the WoSCC database were obtained with these advantages in mind.

Data Analysis and Visualizing
Using bibliometrics, it is possible to identify the key quantitative variables of a given research stream.It is also possible to follow the proposed five steps of the science mapping workflow.The data were analyzed using the R-based open-source software Bibliometrix [37][38][39][40].First, a performance analysis of these articles was performed, including basic statistics, authors, number of publications, journals, institutions, and countries.
Data analysis requires descriptive analysis and network inference.Different approaches have been developed to extract networks using different units of analysis.In this study, co-occurrence and co-citation analyses were used.Co-occurrence analysis creates networks using keywords such as a common author, word, country, etc.For example, cooccurrence analysis uses the most important words or keywords in documents to examine the conceptual structure of a research area.It is the only method that uses the actual content of documents to create a measure of similarity.Paraphrase analysis produces semantic maps that facilitate an understanding of the cognitive structure of a domain.It can be applied to document keywords, abstracts, or full texts.The unit of analysis Is usually not a document, author, or journal, but a concept or keyword [37].
The co-citation link is established by the authors citing the documents under review.It examines the cited documents and helps to identify changes in paradigms and schools of thought when analyzed over time.The co-citation of two articles occurs when both are cited in a third article.Thus, co-citation is the counterpart of bibliographic coupling [37].
The Bibliometrix R-package allowed us to use the conceptual structure function to perform a multiple correspondence analysis (MCA) to draw a conceptual structure of the field and K-means clustering to identify clusters of documents that express common concepts.In this study, MCA was used for data reduction."Biblioshiny" was also used as an application that provides a web interface for Bibliometrix to create a scientific map, including a co-citation network and co-word analysis.In the final stage, the most prominent types of electronic records were analyzed through a document analysis.

The dataset records the total number of citations received from 1983 to 2023.The low number of citations between 1983 and 1993 suggests a lack of interest in the subject during that time.Citations show an irregular increase from 1994 to 2005, with 2006 and 2017 experiencing exceptionally high numbers.The recent decline in citations during 2022 and 2023 can be attributed to the large volume of new publications.Between 1983 and 1993 only one publication per year was recorded, suggesting minimal attention towards the research area during this time period.However, the number of publications has surged since 2012 and has reached its peak in the past two years, as depicted in Scheme 1.

The studies listed in Table 1, which have been cited the most in the field of HIM address several significant matters.The study by Mandel et al. (2016) [41] addresses the integration of medical applications across HISs through the Substitutable Medical Applications and Reusable Technologies (SMART) on the Fast Health Interoperability Resources (FHIR) platform.The objective of this research is to facilitate more effective communication between information systems and a more efficient management of patient information [41].Kraemer et al. (2017) [42] examined the application of fog computing in the healthcare industry.They found that fog computing can perform a variety of tasks from wireless devices to high network layers, and that it offers a balance between privacy and reliability concerns.The studies listed in Table 1, which have been cited the most in the field of HIM, address several significant matters.The study by Mandel et al.

(2017) [42] examined the application of fog computing in the healthcare industry.They found that fog computing can perform a variety of tasks, from wireless devices to high network layers, and that it offers a balance between privacy and reliability concerns.The "All Aspects of Health Literacy Scale (AAHLS)" [43] describes an instrument's development and pilot that aims to measure health literacy in a multidimensional way.This scale provides critical dimensions for HIM, including the effective use of health information, effective communication with healthcare providers, and the management and evaluation of health information.Thus, the study aims to quantify the essential skills that are necessary for patients and healthcare professionals to make informed and impactful decisions [43].
The study by Kim et al. (2009) [44] focuses on the use and effectiveness of PHRs in a low-income and elderly population.In terms of HIM, the study highlights that PHR systems often fail to reach those that are the most in need but the least able to use them.Several factors such as limited access to technology, limited proficiency in computer and internet usage, an inadequate comprehension of health information, and restricted physical or cognitive abilities impair this population's effective use of PHR systems.The study indicates that the use PHRs is restricted to only 13% of the population, and mostly during times when personal assistance is available.This implies that in order to create and implement effective HIM tools, socio-economic and age-related factors must be taken into consideration [44].
Lustria's (2011) [45] study examines the digital divide in the use of eHealth technologies in the US and proposes solutions, such as web-based tools, to bridge this gap.Giakoumaki et al. (2006) [46] discuss the potential of digital watermarking technology in HIM to provide a solution for the safe and efficient storage and distribution of medical data.Ancker et al. (2015) [47] investigated how people with multiple chronic conditions handle their health information.This process encompasses several interactions between patients and providers and involves numerous tasks related to HIM, known as the "invisible work" [47].Pratt et al. (2006) [48] explained how personal HIM helps individuals to take a more active role in their healthcare.Nouri et al. (2018) [49] provide criteria for assessing the quality of mobile health applications and discuss how these applications should follow a standard in terms of health services and information management.
The tenth most cited paper [50] examines the emergence of HIM in the household (HIMH) and its potential implications for consumer health informatics (CHI).The argument advanced in this paper proposes that a single individual is usually accountable for obtaining, handling, and arranging an assorted range of health information pertinent to HIM within the home.Paper-based tools continue to be extensively used, and households develop strategies to store information according to the urgency of their needs.This research highlights that the complex and robust strategies devised at home can effectively assist individuals in managing their personal health information, thereby contributing to consumer health innovations [50].
Overall, these studies address various dimensions of HIM, such as the role of technology, the need for standardization, personal and societal factors, and security and privacy.Technological approaches and methodologies are crucial in enhancing overall efficiency, security, and system accessibility.Nevertheless, these studies indicate that it is necessary to consider various cultural and social implications.
