Relationship between mental fatigue and burnout syndrome in remote workers during the COVID-19 pandemic: an integrative review.

This study aimed to analyze the scientific evidence available in the literature addressing the relationship between mental fatigue and burnout associated with teleworking during the COVID-19 pandemic through an integrative review. This review searched the following databases: PubMed, Scopus, Taylor & Francis, Embase, ScienceDirect, and SciELO using the DeCS and MeSH health sciences descriptors. The included articles were published between March and December 2021, during the pandemic. Of a total of 224 results, 215 articles were excluded and 9 were considered for the preparation of this integrative review. Mental fatigue was related to technostress, somatic symptoms such as anxiety and insomnia (p < 0.05), and loss of motivation (p < 0.05). Burnout was positively associated with work overload, high interdependence, and lower role clarity. The presence of a stressful factor and a protective factor was evidenced in burnout: intrusive leadership and workaholism, respectively. Greater exhaustion was observed in workers belonging to generation X (41 to 55 years old). Mental fatigue is related to exhaustion in the productive, physical, and psychological dimensions of individuals. Addiction to work has moderated this phenomenon, however, it is urgent to limit and optimize work hours as well as promote disconnection and rest among workers within the framework of a healthy work policy.
