  Industry 4.0 in health care has evolved drastically over the past century. In
fact, it is evolving every day, with new tools and strategies being developed
by physicians and researchers alike. Health care and technology have been
intertwined together with the advancement of cloud computing and big data. This
study aims to analyze the impact of industry 4.0 in health care systems. To do
so, a systematic literature review was carried out considering peer-reviewed
articles extracted from the two popular databases: Scopus and Web of Science
(WoS). PRISMA statement 2015 was used to include and exclude that data. At
first, a bibliometric analysis was carried out using 346 articles considering
the following factors: publication by year, journal, authors, countries,
institutions, authors' keywords, and citations. Finally, qualitative analysis
was carried out based on selected 32 articles considering the following
factors: a conceptual framework, schedule problems, security, COVID-19, digital
supply chain, and blockchain technology. Study finding suggests that during the
onset of COVID-19, health care and industry 4.0 has been merged and evolved
jointly, considering various crisis such as data security, resource allocation,
and data transparency. Industry 4.0 enables many technologies such as the
internet of things (IoT), blockchain, big data, cloud computing, machine
learning, deep learning, information, and communication technologies (ICT) to
track patients' records and helps reduce social transmission COVID-19 and so
on. The study findings will give future researchers and practitioners some
insights regarding the integration of health care and Industry 4.0.
