Effectiveness of Digital-Based Interventions on Physical and Psychological Outcomes Among Cancer Patients: A...

Evolving digital technology has paved the way for endless potentiality. Leveraging on digital technology for healthcare purposes can target cancer patients, thus improving physical and psychological symptoms. Nevertheless, there is limited consolidated evidence on the effectiveness of virtual reality (VR) and mobile applications. This review aimed to synthesize evidence concerning the effectiveness of VR and mobile-based interventions on physical (pain, fatigue, and sleep) and psychological (anxiety and depression) outcomes among cancer patients.

A comprehensive literature search was conducted on ten electronic databases, ongoing trials, and grey literature, reported between 2013 to 2023. All randomized controlled trials (RCTs) examining VR and mobile-based interventions on the physical or psychological outcomes among people with cancer were included. Two independent reviewers screened records for eligibility, appraised methodological quality, and extracted data from included studies. The Cochrane Risk of Bias tool was used for data appraisal, and a modified Cochrane data extraction form was used for data extraction. Meta-analysis and subgroup analysis were used to analyze data.

In total, 43 studies were included. VR relaxation videos and game-based activities were efficacious in improving cancer-related pain. Mobile applications with educational content, symptom monitoring, relaxation videos, teleconsultation, and regular reminders contributed to positive effects on all outcomes. Mindfulness practice appeared to improve sleep quality, anxiety, and depression. Intervention effects sustained at least 6 months for all outcomes, except sleep.

VR and mobile-based interventions had the potential to improve pain, fatigue, sleep, anxiety, and depression at post-intervention. Future RCTs are required to further test both digital interventions on specific types of cancer on multiple research settings.

VR and mobile-based interventions can be offered in clinical settings to help cancer manage their pain, fatigue, sleep, anxiety, and depression. VR relaxation videos, game-based activities, teleconferences, mindfulness, education, and system reminders can be included.
