Purpose: This study systematically reviewed and synthesized the evidence on the effectiveness of mobile health (mHealth) interventions in improving medication adherence among patients with cardiovascular disease. Methods: This systematic review included randomized controlled trials that evaluated the effects of mHealth interventions on medication adherence among patients with cardiovascular disease. PubMed, the Cochrane Library, CINAHL, and Embase were searched for peer-reviewed studies and grey literature published in English between January 1, 2013, and July 31, 2025. The Cochrane Risk of Bias 2 (RoB 2) tool was used to assess the risk of bias in the included studies. R software ver. 4.5.2 was used to perform the meta-analysis. Results: Fifty-two studies were included in the systematic review, of which 20 were included in the meta-analysis. The pooled analysis demonstrated a significant improvement in medication adherence among patients with cardiovascular disease receiving mHealth interventions, with a moderate to large effect size (Hedges’ g=0.72; 95% confidence interval, 0.20–1.25; p<.001), despite substantial heterogeneity (I2=97%). However, a considerable proportion of the included studies were assessed as having a high risk of bias, which may limit the internal validity of the findings. Subgroup analyses indicated that the effects of mHealth interventions on medication adherence did not differ significantly according to intervention type, duration, or outcome measurement tools. Conclusion mHealth interventions appear to be effective in improving medication adherence among patients with cardiovascular disease. However, these findings should be interpreted with caution because of the high risk of bias and substantial heterogeneity among the included studies. Future research should explore the use of emerging technologies, such as artificial intelligence and virtual reality, to address medication non-adherence (PROSPERO registration number: CRD42023450502).

Purpose: Awareness of environmental control is considered a major influence on the performance of asthma self-management behaviors that are involved in maintaining effective control of asthma. The aim of this study was to investigate whether immersive virtual reality (VR) education is effective in environmental control education for asthmatic children. Methods: Thirty asthmatic children aged 9 to 13 years with aeroallergen sensitization were enrolled. Environmental control education for asthmatic subjects were performed using either immersive VR (VR group) or conventional leaflets provided by asthma specialists (control group). Five questionnaires, such as awareness of environmental control, memory, assessment of intent to act, satisfaction test, and asthma control test (ACT) questionnaires were used for estimating the effects of education. Results: Awareness of environmental control, memory, and intent to act scores were significantly increased after education in both groups and the scores were maintained high until 4 weeks after education. In both group, ACT scores were maintained high scores before and 4 weeks after education. Satisfaction scores were very high in the VR group. Conclusion The increased scores in awareness of environmental control and intent to act indicate that the environmental control education using VR is worthy of attention as an effective educational tool for asthma management. Application of further developed techniques, including active environmental intervention by participants in VR, could be applied to effective asthma management.
