Telemedicine service can effectively improve the diagnosis and treatment, rationally allocate medical resources, and fully reduce medical expenditure, so as to meet people′s health care needs. As introduced by the authors, Beijing Geriatric Hospital provides telemedicine services for chronic diseases guidance, medical consultation and home care services through mobile App, realizing hierarchical medical services, resource sharing and service collaboration in the region, and making up for the shortcomings of time and space in conventional model of face-to-face services. However, in the process of promotion and application, a series of ethical issues have also been found, such as the change of doctor-patient relationship, the protection of patient privacy, the safety of data and information, and the management of medical quality. By discussing the ethical risks in the telemedicine environment and thinking about the relevant countermeasures, we can promote the establishment of a corresponding medical ethics system and promote the sustainable development of telemedicine.
