Article:

This study aimed to examine the process of establishing a telenursing service for COVID-19 patients with mild or no symptoms admitted to a community treatment center (CTC). The process of establishing the service was reviewed, and the degree of satisfaction with the provided service was investigated based on the medical records the patients submitted at their discharge from the CTC. A total of 113 patients were admitted; the patients themselves entered the self-measured vital signs and symptoms of COVID-19 infection to the electronic questionnaires and mobile application. The nurses implemented remote nursing based on the patients' input data. The educational materials, including the video for self-measuring vital signs and the living guidelines, were prepared and arranged in advance. The telenursing protocol regarding the whole process from the patients' admission to their discharge was used and applied to five other CTCs. The non-contact counseling service's satisfaction and convenience scores were 4.65 points and 4.62 points, respectively, out of 5 points. The non-contact nursing counseling service played an important role in monitoring patients' medical conditions during the spread of COVID-19. This experience of establishing telenursing services to the CTC provides a clear direction to innovate healthcare services in future disasters.
