Tele‐mental health during the COVID‐19 pandemic: A systematic review of the literature focused on technical aspects and challenges

INTRODUCTION: Mental disorders are the leading cause of disability and the second leading cause of death worldwide, which leads to the death of more than 9 million people annually. The global impact of the Coronavirus epidemic on mental health includes insomnia, anxiety, and depression. Therefore, given the current situation, innovations such as telemedicine to provide prevention and treatment services for people with mental disorders seem necessary. METHODS: A literature review was performed according to the preferred items to report in systematic reviews and meta‐analyses (PRISMA). Covering a period from January 2020 to July 2023, we conducted a systematic literature search on five electronic databases (PubMed‐Mesh, Scopus, Web of Science, Science direct, and PsycInfo). The search strategy included three categories of keywords: Mental health, Tele, COVID‐19. RESULTS: A total of 112 articles were identified by searching the databases of published articles, 13 articles met our inclusion criteria. A total of 76.2% of them were related to patients with stress, anxiety, and depression issues. We found that the real‐time method has been the most common method used to communicate between the physician and the patient (92.3%). The communication technologies used also included telephone, video call, video conference, and E‐mail. During these communications, data was exchanged in text, voice, and video formats. In three studies (27%), interoperability with other systems was mentioned. In addition, 69.2% of the studies reported challenges, the most important of which were access to electronic and communication devices, network connection problems, audio and video problems, and privacy issues. CONCLUSIONS: Considering the many advantages of telemedicine technology in the field of mental health, the need to use this technology in developing countries, including our country, is obvious. But the application of these technologies requires the investigation of technical aspects and challenges related to them as much as possible, which have been seen in few studies.
