Effects of digital psychological interventions on physical symptoms in cancer patients: A systematic review and meta-analysis

摘要

Purpose: This meta-analysis was to assess the efficacy of digital psychological interventions to improve physical symptoms (i.e., fatigue, pain, disturbed sleep, and physical well-being) among cancer patients, as well as to evaluate the variables that possibly moderate intervention effects.Methods: Nine databases were searched for the literature up to February 2023. Two reviewers independently conducted a quality assessment. Effect sizes were reported as the standardized mean difference (Hedge's g) and estimated using a random-effects model. Results: The meta-analysis included 44 randomized clinical trials comprising 7200 adults with cancer. Digital psychological interventions were associated with significant improvements in short-term fatigue (g =-0.33; 95% CI,-0.58 to-0.07) and disturbed sleep (g =-0.36; 95% CI,-0.57 to-0.15), but with non-significant changes in pain (g =-0.23; 95% CI,-0.68 to 0.21) and physical well-being (g = 0.31; 95% CI,-0.18 to 0.80). Additionally, no alleviation in long-term physical symptoms was observed. In subgroup analysis, results suggest that the country significantly moderated the effectiveness of digital psychological interventions in alleviating fatigue.Conclusions: Digital psychological interventions can be effective for improving short-term fatigue and disturbed sleep in patients with cancer. Clinicians could consider digital psychological interventions as a possible and efficient addition to better manage some of the physical symptoms during and after cancer treatment.
