The health sector is considered one of the areas that are most vulnerable to technological development, so it is being affected by digitization, trans- forming the way healthcare is providing, from the communication between patients and healthcare providers to the government and the interested parties [1]. As the estab- lishment tools grow, eHealth is next alongside. Therefore, the specific description of the term has experienced radical modifications and technical specifications, the latest available ones concerning the concept referred to as the industry 4.0. In its broader 116 http://www.i-jim.org https://doi.org/10.3991/ijim.v15i18.25531 mailto:Ishamuddin@unikl Paper—Impact of Industry 4.0 on Healthcare: A Systematic Literature Review (SLR) from the Last Decade meaning, the concept of IR 4.0 can be viewed as an explicit legislative pledge to nur- ture a set of technology to enhance the overall progress [2]. According to [3], they are launching IR 4.0 concept established enormous possibilities for many industry sectors to enhance their processes. Consequently, they can increase their productivity, cost efficiency, consistency, excellence, and suppleness. One crucial area that can efficiently take advantage of this concept is healthcare. Emerging requirements of healthcare worldwide demand effi- cient and effective medical services that can manage the requirements. Technologies enhance the abilities of traditional healthcare infrastructure worldwide, and digitali- zation is a prominent enabler in the current healthcare crisis [4]. Industry 4.0 enables many new technologies, like blockchain, big data, cloud computing, and IoTs, to track patients’ medical records. That more accessible for the healthcare professionals to understand the patient’s history and deal accordingly [5]. However, the COVID-19 pandemic challenges the healthcare robustness around the globe, and healthcare facili- ties are failed to perform. Developed and underdeveloped countries’ healthcare is fully occupied during the pandemic. However, technological advancement plays a pivotal role during a disaster [6]. Healthcare professionals used the IR 4.0 technologies to test the suspects and control the transmission. Recent healthcare requirements lead to more efficient services that can provide medical services for distant residents and reduce the loads on the hospitals [7]. Healthcare applications also enhance medical awareness among the users, especially elderly patients who require more attention. The current study aims to identify the impacts of Industry Revolution 4.0 (IR 4.0) on healthcare. The recent development and requirements for healthcare infrastructure and future technologies in the published research are analyzed in the current study. The current study included articles related to IR 4.0 and healthcare. 2 Materials and methods During the reporting of the findings and the development of the research structure, authors worldwide use PRISMA statement 2015. The systematic literature review (SLR) is a manual to improve the reliability of the reviews and meta-analysis. The PRISMA statement guide describes the overall research procedure for picking and refusing articles in the systematic review. This SLR ground research is restricted to available information on industry 4.0 and healthcare systems—Scopus’s database, applied for the literature mining. The keywords are used “industry 4.0 AND healthcare” in the search bar. The database’s total results are 297, and the subject is selected for the current study engineering, computer science, medicine, social science, nursing, health professional, business, management and accounting, economics, econometrics, and finance. The subject selections shrink the results to 285 articles. Some critical inclusion and exclusion criteria for this review were published articles in English and industry 4.0 and healthcare. The review papers and articles are included in the review. Later, a careful screening was performed for each identified classification to determine relevant records, and only 48 studies were selected to be included to synthesize the review., Figure 1 shows the overall PRISMA statement 2015 selection and rejection process of the current study in detail. iJIM ‒ Vol. 15, No. 18, 2021 117 Paper—Impact of Industry 4.0 on Healthcare: A Systematic Literature Review (SLR) from the Last Decade Fig. 1.

VOS Viewer software analyses the content of published literature—data clus- ters generated on the text to cluster related ideas. The current study found that authors’ terms and keywords defined further in the publications’ indexing process detailed in the databases are perfectly appropriate for bibliometric analysis aiming to disclose the exam- ining field’s structure. As a result, we used both types of keywords for the co-occurrence analysis within the study region related to digital fintech services. The investigation had 48 records in total, with 179 keywords provided by the dataset. Only the most frequent 96 keywords occurring in a total of 10 documents were firmly defined and picked. The content analysis findings are depicted in Figure 4—the cluster is divided into three large clusters, depicted in distinct colors. Digital technology and COVID-19 are all associated with the blue cluster. Cloud computing, hospital, and algorithm IOTs represent green clusters—finally, the purple cluster healthcare system, algorithm, and security. In the following part, each cluster is further investigated to find the finch services. Fig. 4. The classification of literature using the VOS viewer 120 http://www.i-jim.org Paper—Impact of Industry 4.0 on Healthcare: A Systematic Literature Review (SLR) from the Last Decade 2.3 Healthcare system The healthcare sector evolved from 1.0 to 4.0, where healthcare 1.0 was the more significant the doctor oriented, and Healthcare 2.0 substituted instruction manual records with an electronic healthcare record (EHRs). Healthcare 3.0 was patient-cen- tric, and Healthcare 4.0 manages cloud computing (CC), fog computing (F.C.), Internet of things (IoT), and telehealthcare technologies available to share data between the various stakeholders [8]. Setting up a safe and secure procedure for healthcare 4.0 has always been a difficult task. Collaboration between doctors is improved, as health care professionals can efficiently come together, organize their events, share their infor- mation about the patients, and guarantee to deliver the best-synchronized care [9]. According to [10], medication 4.0 has brought about an enhanced attempt to build the platform, both on the hardware level in Addition to the underlying software point. Such a vision has resulted in the development of healthcare IoT (H-IoT) methods. The funda- mental facilitating technologies consist of the interaction systems sandwiched between the detecting nodules and the CPUs and the processing procedures for producing a production from the data gathered by the devices. These devices continuously measure, progress, detain, and store biometric data such as body position, weight, and move- ments, sleep quality, blood pressure, blood oxygen saturation, body temperature, heart rhythm and rate, blood oxygen, fatigue levels, and respiration rate [11]. However, some challenges remain in the framework of primary health systems, such as exchanging electronic health records, but have yet to be fixed [12]. According to [13], breakthroughs in blockchain technology have improved transactions involving medical records, insurance billing, and smart contracts, permitting permanent access to and security of data while still providing a distributed database of transactions. Blockchain technologies and considerable data involvement enhance the abilities of the healthcare system in recent times. Big data has the potential to support a variety of medicinal and healthcare operations, including disease control and patient care. Big data is a large amount of data saved due to enhancements in various cloud comput- ing and wireless communication technologies [14]. Focus On the identified issues, the Internet is a backbone for delay mitigation using 5G networks for future ultra-reliable low-latency applications such as Healthcare 4.0, Business 4.0, virtual world and artifi- cial intelligence, and intelligent education [15]. The healthcare system in industry 4.0 is mainly dependent on digital technologies, and high-speed Internet is bringing changes with effectiveness in the healthcare system. The old, dated technologies are now fully cloud computing-centric in recent times. Table 2 is showing the details of the author, segment, and settings for the research. Table 2.

According to [17] Instead, Healthcare 4.0 is defined by the adoption of three major paradigms: the Internet of Things, Big Data, and Cloud Computing, which are revolutionizing eHealth and its entire ecosystem in the same way that Industry 4.0 is revolutionizing the manufacturing sector. The rapid adoption and evolution of cloud/edge computing, Internet of Things (IoT), and big data technologies are transforming eHealth and the entire Industry 4.0 in healthcare applications [18]. Healthcare Industry 4.0 allows for increased productivity, Flexibility in various areas, including production and speed. Both manufacturing and market processes are improved product quality and productivity and changing business models by altering interactions with the value chain and competitors and customers [19]. The edge computing framework has piqued many people’s attention in recent years as a viable alternative to traditional cloud-based approaches for reducing interac- tion timing and the massive amount of data flowing from the Internet of Things (IoT) devices to the Internet [20]. According to several academics, Edge Computing collects computers, devices, and network resources that generate and collect data and send it to remote data centers in the cloud. The works of these researchers depict Edge Computing from a variety of perspectives, including frameworks, skills, software technologies, and characteristics [21]. The Cloud-centric execution of IoT applications barely meets such requirements because Cloud datacentres are located several hops away from IoT devices. Fog com- puting, a Cloud at the Edge network extension, can run these applications closer to data sources. As a result, fog computing can improve application service delivery time while avoiding network congestion [20]. Traditional healthcare is transforming into virtual, distributed care that heavily relies on cutting-edge technologies such as artificial intelli- gence (A.I.), deep learning, data analytics, genomics, home-based healthcare, robotics, and 3D printing of tissue and implants. In the future, fundamental shifts will reshape Table 2.

The study of [23] concluded that every nation’s global news is dominated by Industry 4.0, which is ushering in the fourth generation of indus- trialization. Digitalization is an essential factor in this process, and the prospects of Augmented Reality (A.R.) and Virtual Reality (V.R.) are closely monitored by various business houses from all sectors around the world. Cloud technologies are enhancing the healthcare system’s abilities and patient care [24]. Many advancements in tech- nology nations are evolving healthcare infrastructure using these technologies under IR 4.0.

For addressing the numerous problems associated with this viral pandemic, various advanced technologies must be introduced. Industry 4.0 consists of advanced health- care and information technologies used to meet the customized needs of various human beings in less time [25]. According to [26], during the COVID-19 pandemic, disrup- tive technologies reduce the burden on the healthcare team. Innovative devices can be used to monitor patients infected with COVID-19. For COVID-19, public health organizations recommend that disruptive technologies play a critical role in public health. Industry 4.0 technologies offer an intelligent solution to complex services and care. Using these technologies, organizations can create a better hospital management system and make human life more comfortable by reducing errors in the treatment process. So, this allows for quick and much more real-time assessment, as well as minor irritation throughout the entire testing process [27]. During the COID-19 pan- demic, technologies play a vital role in detecting the suspects of virus transmission. Initially, it was difficult for healthcare professionals and many healthcare profession- als. Digital technologies create an atmosphere secure for healthcare workers [28]. Mobile applications, robots, Wi-Fi cameras, scanners, and drones are used to control iJIM ‒ Vol. 15, No. 18, 2021 123 Paper—Impact of Industry 4.0 on Healthcare: A Systematic Literature Review (SLR) from the Last Decade the transmission of the virus. Industry 4.0 influenced digital technologies’ significant contribution to pandemic control [29]. However, Hospitals deployed a complete automation system/platform for accessing healthcare services because of the deep convergence of automation technologies and health informatics driven by Industry 4.0. Mainly, online appointment services can be accessed directly from the Internet by using an automation booking device, a mobile app, or a permitted platform. It has dramatically facilitated the lives of young patients who are adept at using the Internet [30]. According to [31], healthcare 4.0 is a rela- tively new term derived from Industry 4.0. Innovative health, mHealth (mobile health), wireless health, eHealth, online health, medical I.T., telehealth/telemedicine, digital medicine, health informatics, pervasive health, and health information systems are examples of data-driven digital health technologies in healthcare 4.0. That influenced the fourth paradigm, which is data-intensive technological innovation. It also discusses digital frontiers and disruptive technologies propelling new business opportunities and value chains in the healthcare industry. Digital technologies are equally effective for young and adults’ health perspectives. New business models for delivering healthcare, behavior support, and health information via social media are driven by technology and consumer behavior [32]. This new situation has the potential to increase patient safety. Before they can effectively incorporate social media into their business model, businesses must achieve certain levels of knowledge, sophistication, and social media strategy integration [33].

The keywords “Industry 4.0 AND healthcare” were decided to enter the search bar for the early extracting data. The literature was chosen systematically to avoid duplication and irrelevant records. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) create the plan of what data should have been included and excluded from system- atic reviews and meta-analyses. The primary data is derived from Scopus. The filtra- tion method is the same, and the data is finally merged on a single Microsoft Excel sheet. The present study classifies the healthcare facilities reported in the literature as being influenced by Industry 4.0. Researchers cover various topics, including Industrial Internet, digital technologies, healthcare systems, healthcare 4.0, and cloud computing. Used For categorization of literature, the author’s keywords and VOS viewer results yield the same results. The VOS viewer was used for data mining in the current study. We also count the number of times the terms appear together to identify fintech-related literature. Figure 5 is showing the outcomes of industry 4.0 and the healthcare system. Fig. 5.
