Effects of using WeChat/WhatsApp on physical and psychosocial health outcomes among oncology patients: A systematic review.

The purpose of this systematic review is to summarize the potential effects of the WeChat and WhatsApp mobile applications in cancer management. This systematic review was written in accordance with PRISMA guidelines. CINAHL, PubMed, ProQuest Nursing and Allied Health Database, PsycINFO, PsycARTICLES, and ERIC were utilized for the literature search. Articles were included if they evaluated the outcomes of using WeChat/WhatsApp for cancer management, and excluded if they were qualitative studies, not published in peer-reviewed journals, protocols for a future study, or conference abstracts. 20 studies were included in this systematic review, with a total sample of 3110 participants. Interventions were utilized to share educational information with participants, follow-up after surgical operations, and in clinical communication. Outcomes, including pain, medication adherence, self-efficacy, quality of life, and depression, were statistically significantly improved in the WeChat/WhatsApp intervention groups in comparison to the control groups or to baseline measurements of the study participants. Outcomes of sleep and rehospitalization rate were improved without reaching statistical significance. Outcomes of anxiety, fatigue, and adverse drug reactions were found to be conflictive among included studies. This systematic review suggested that use of WeChat/WhatsApp on cancer management might improve various physical and psychosocial health outcomes among oncological patients. Limitations of the study include solely reviewing English language articles published in academic journals and most of the studies being from one country. Future research should be conducted in various countries among diverse communities, including rural areas, to ascertain the effects of WeChat/WhatsApp in different populations.
