eHealth and mHealth Interventions in the Treatment of Fatigued Cancer Survivors: A Systematic Review and Meta-Analysis

Abstract

Objectives

To (1) evaluate existing eHealth/mHealth interventions developed to help manage cancer-related fatigue (CRF); and (2) summarize the best available evidence on their effectiveness.

Methods

A comprehensive literature search of PubMed, MEDLINE, EMBASE and the Cochrane Library up to November 2016 was conducted. Study outcomes were extracted, tabulated and summarized. Random effects meta-analyses were conducted for the primary outcome (fatigue), and the secondary outcomes quality of life and depression, yielding pooled effect sizes (r) and 95% confidence intervals (CI).

Results

For eHealth interventions, our search of published papers identified nine completed studies and six protocols for funded projects underway. No studies were identified for mHealth interventions that met our inclusion criteria. A meta-analysis of the nine completed eHealth studies revealed a statistically-significant beneficial effect of eHealth interventions on CRF (r = .27, 95% CI [.1109 – .4218], p < 0.01). Therapist-guided eHealth interventions were more efficacious then self-guided interventions (r = .58, 95% CI: [.3136 – .5985, p < .001). Small to moderate therapeutic effects were also observed for HRQoL (r = .17, 95% CI [.0384 – .3085], p < 0.05) and depression (r = .24, 95% CI [.1431 – .3334], p < 0.001).

Conclusions

eHealth interventions appear to be effective for managing fatigue in cancer survivors with CRF. Continuous development of eHealth interventions for the treatment of CRF in cancer survivors and their testing in long-term, large-scale efficacy outcome studies is encouraged. The degree to which mHealth interventions can change CRF in cancer survivors need to be assessed systematically and empirically.
