An insight in the future of healthcare: integrating digital twin for personalized medicine

Purpose: An increasingly popular concept in numerous fields is a digital twin, which is a virtual counterpart of an object. This technology is causing important advances for the benefit of patients in the context of healthcare. A digital twin is a computer-generated depiction of an actual product that mimics its information model, action, interaction processes, and product, as well as examines how they might be used to improve the organization of health care and the constraints linked to this innovative technology. This paper will investigate the utilization of Digital Twin systems, processes, and products, as well as examine how they might be used to improve the organization of health care and the constraints linked to this innovative technology. Methods: For research on Digital Twins and their use in healthcare published recently, a brief overview of the literature was reported. The databases of this study are published from 2002 to 2023 and the review was written in English. The Digital twin technology which does not support the Healthcare studies was excluded. This assessment is focused on their contribution to the Digital Twin, which aims to enhance user experience in healthcare from a system engineering and human aspects perspective. Results: The Digital Twin in healthcare has been growing since 2002 from 0 studies to 25 in 2023, with 15 studies available in 2023(N = 15 studies). The knowledge reported on the contributions or applications of each Digital Twin in healthcare, and its roles. The four main roles of digital twins in healthcare systems are health management and well-being promotion (n = 3), operational control (n = 12), information management (n = 5), and safety management (n = 4). The usage of digital twins in healthcare has the potential to stop unanticipated harm from occurring to patients while providing care. They may also be utilized to distinguish and manage the systemic concerns posed by crises. All stakeholders' access to real-time information and privacy are guaranteed by digital twins in the healthcare industry. Additionally, by enabling healthcare practices and fostering high levels of system efficiency by ensuring that healthcare facilities function properly and provide every patient with high-quality care, they help enhance self-care capacities. Conclusion: This assessment is focused on their contribution to the Digital Twin, which aims to enhance user experience in healthcare from a system engineering and human aspects perspective. This review explores and analyses opportunities for implementing digital twin technology in the Industrial Revolution 4.0 by considering various functionalities.
