Introduction
In May 2018, World Health Organization member countries passed WHA Resolution 71.7 at the World Health Assembly, addressing Digital Health. The resolution highlights the potential of digital technologies to achieve the Sustainable Development Goals (SDGs) of the 2030 Agenda, recognizing these technologies as essential tools to promote comprehensiveness and expand access to health services (1).
This resolution emphasizes the importance of all member countries promoting and utilizing digital technology as a means of strengthening public health resilience. This includes improving access to and monitoring, sharing and use of quality data, promoting direct engagement of citizens, health workers, and government, building capacities for rapid response to public health incidents and emergencies, harnessing the potential of digital information and communication technology to enable multidirectional communications, feedback loops, and data-driven adaptive management (2). The spread of connected devices and applications and technological advances in healthcare are changing the way medical institutions and their patients relate to each other. Currently, it is possible to rely on automated mechanisms to increase the productivity and safety of health processes. In addition, these technological innovations have the potential to impact the reduction of costs for the system, optimizing tasks and services, increasing the quality of care and expanding access to health care (3).
The integration of advanced digital technologies in the healthcare industry, known as Health 4.0, has the potential to profoundly transform healthcare delivery. This concept emerges from the Fourth Industrial Revolution, which uses technologies such as the Internet of Things (IoT), Big Data, Artificial Intelligence, and Augmented Reality to optimize operations and improve the patient experience (4). The adoption of these technologies allows for a more personalized and predictive approach to health care, providing better management of resources and reducing operating costs (4).
Health 4.0 is based on creating an intelligent and interconnected ecosystem where medical devices, information systems, and healthcare professionals collaborate in an integrated manner. This ecosystem facilitates the collection, processing, and analysis of large volumes of data, allowing for faster and more accurate medical interventions (5). The digitalization of health processes, therefore, not only improves operational efficiency but also promotes the accessibility of services, benefiting both patients and health professionals (3).
One of the main benefits of Health 4.0 is the improvement of patient safety and the optimization of clinical processes. Technologies such as cyber-physical medical systems (MCPS) enable the automation of routine tasks and continuous monitoring of patients, while Big Data analytics help identify health trends and make informed decisions (4). These innovations increase operational efficiency and provide a more patient-centric experience with real-time, personalized care (5).
Despite the numerous benefits, the transition to Health 4.0 presents significant challenges. Issues such as data security and privacy, interoperability between different systems and devices, and the need to train health professionals to use these new technologies are barriers that need to be overcome (4). Additionally, implementing these technologies requires substantial investments in infrastructure and training, which can be an obstacle for many healthcare organizations (5).
The adoption of Industry 4.0 technologies in the healthcare industry also faces regulatory and ethical issues, especially related to the use of sensitive personal data. The need to ensure compliance with data protection standards and the construction of an environment of trust between patients and health professionals are critical aspects for the success of Health 4.0 (3).
In addition, it is important to consider the role of international collaboration and knowledge exchange in promoting Health 4.0. Partnerships between governments, academic institutions, and private companies can accelerate the development and implementation of advanced health technologies. These collaborations can facilitate the sharing of best practices and the standardization of processes, helping to overcome cultural and technical barriers that may hinder the widespread adoption of Health 4.0 (5).
The objective of this article is to identify the barriers and challenges that impact the implementation of Health 4.0 concepts and principles, in addition to exploring and proposing solutions to mitigate them. The systematic investigation of the barriers to the implementation of Health 4.0 technologies contributes to a comprehensive understanding of the challenges that need to be overcome.
The identification of these barriers, along with the proposal of viable solutions, seeks not only to facilitate the adoption of these innovative technologies in the field of health, but also to promote a significant transformation in the quality and efficiency of the health care provided.
Methods
A systematic review of the literature was carried out, following rigorous stages of selection, analysis and synthesis of the selected studies. The systematic review allowed the identification of the best available scientific evidence on the subject, critical evaluation and synthesis of the results obtained. Four steps were defined as illustrated in Figure 1:
The first stage is the characterization of the study and six activities take place. The first is the definition of the theme, with Health 4.0 as its focus. Next, the keywords that were used for the elaboration of the search term "string" were defined, which were then applied to the search platforms chosen because they are already known as important sources of data for the research developed.
The selection criterion was defined as the extraction of works such as articles, journals, theses and book chapters, published in the period from 2018 to 2023.
The keywords and synonyms used in the search were: Health 4.0, Healthcare 4.0, Barrier, Challenges. Implantation and Implementation. The selected databases were: Scopus, IEEE, Pubmed, Science direct, Web of Science and Google scholar. The search terms used in each search platform were: ("health 4.0" OR "healthcare 4.0") AND ("barriers" OR "challenges" OR "deployment" OR "Implementation").
In the next stage, data collection, two activities took place. The first was the identification of the studies, which consisted of searching for the studies using the terms defined in the previous stage and applying the filters available on each platform regarding the type of work and the year of publication. Thus, the following amounts of papers were obtained: IEEE (225), Scopus (131), Web of Science (81), PubMed (51), Google Academic (169), Science Direct (215), totaling 872 articles.
Then, the metadata of each work was extracted. This process was carried out by selecting the works found and exporting in text files with the extension bibtex (*.bib) the information such as title, abstract, keywords, authors' names, year of publications, among other data, which does not include the content of the work.
In the data analysis stage, two software programs were used, StArt and Mendeley, divided into seven activities. The first was with planning, that is, with the completion of the protocol established by StArt, where the problem, the objectives of the work, the research question, the data sources, the exclusion/inclusion criteria, the keywords and their synonyms were indicated.
In the second activity, which consisted of identifying the studies, the metadata from the databases of 872 studies were imported using text files (*.bib), where duplication (same works) was identified in 191 studies, leaving 681 articles for the next stages.
The criterion of scoring the works is a prerequisite of the StArt software, through which the number of times in which each keyword was mentioned in the title (15 points), abstract (10 points) or in the keywords (05 points), receives a final score.
Then, in the third activity, selection, the inclusion and exclusion criteria were applied as shown in Chart 1:
As a result of this stage, 492 papers were automatically excluded by the StArt software, leaving 189 papers selected to be analyzed in the next stage.
In the fourth and final stage, performed with StArt, all 189 titles and abstracts were read and the quality criteria established in the protocol were applied. As a result of this stage, 78 papers that were directly related to the research theme were sent to Mendeley for the next activities.
The fifth stage corresponded to the recognition of studies at Mendeley. The work files were imported and inserted into the software in the "pdf" extension. Next, the details of the files were examined, this included the metadata, which includes the title, author, place and year of publication, abstracts, keywords, digital object identifiers (DOI) and the uniform resource locations (URL) of the files on the Internet.
Finally, the sixth and seventh activities of this stage were completed. These included identifying studies and making selections using Mendeley.
50 studies were selected that not only met the objectives and content of the present study, but also met the criteria of document details verified in the previous activity. In the next step, the details of each job were exported to the ".xml" extension using Microsoft Excel for an analysis.
We conclude this section with the two tasks of identifying the studies using Microsoft Excel and summarization with the aid of the artificial intelligence software Quillboat. The file originated from Mendeley and was open in spreadsheet format, with the metadata organized in database format. Then, the information was gathered and organized according to the objective of the work. By reading these articles, topics pointed out by the authors that indicated the focus of the article in question were extracted, and the topics were classified into barriers or challenges.
