The effectiveness of e-healthcare interventions for mental health of nurses: A PRISMA-compliant systematic review of randomized controlled trials

BACKGROUND: Mental health problems, including burnout among nurses, are common and important. With the rapid development of information and communication technologies and the rise in use of smartphones, the use of e-mental health strategies is increasing in public and clinical settings, and initial clinical trials using this intervention have been conducted. This systematic review evaluated whether e-healthcare interventions improve burnout and other mental health aspects in nurses. METHODS: Six electronic databases including MEDLINE (via PubMed), EMBASE (via Elsevier), the Cochrane Library Central Register of Controlled Trials, the Cumulative Index of Nursing and Allied Health Literature, the Allied and Complementary Medicine Database, and PsycARTICLES were searched to collect relevant randomized controlled trials up to January 28, 2021, using e-healthcare interventions for mental health in nurses. The e-healthcare intervention was classified as web-based, smartphone-based, and real-time online interventions. The primary outcome was burnout in this population. Due to the heterogeneity of the interventions used in the included studies, quantitative synthesis was not performed, but included studies were analyzed qualitatively. Also, the details of e-healthcare for the mental health of nurses were analyzed. The methodological quality of included studies was assessed using Cochrane's Risk of Bias tool. RESULTS: Seven randomized controlled trials were included in this study. The 20-minute session of an online form of the emotional freedom technique was reported to significantly improve burnout severity compared to no intervention (P < .001). Other outcomes, such as career identity, quality of work life, workplace bullying, job stress, turnover intention, distress, anxiety, and resilience in nurses, were also reported to be improved by e-healthcare interventions. The methodological quality of the included studies was generally poor. CONCLUSIONS: In conclusion, there was some evidence that e-healthcare interventions may improve mental health outcomes, including burnout in nurses, compared with no intervention. However, due to the poor methodological quality and wide heterogeneity of the interventions and outcomes in the included studies, we were not able to reach sufficiently reliable conclusions. E-healthcare intervention for nurses in the new coronavirus disease era was discussed. High-quality clinical trials in this area should be conducted in the future.
