Telehealth access in remote areas has been a focus for improving chronic disease management through remote monitoring programmes. Not applicable to this review article as it focuses on existing studies rather than conducting new empirical research. Remote monitoring via telehealth showed a significant reduction (P < 0.05) in healthcare costs by $23 per patient annually, with a confidence interval of (18, 28). The review highlights the potential for telehealth to improve chronic disease management and reduce healthcare expenses in remote areas. Further research should evaluate scalability and long-term sustainability of these programmes in different geographical contexts. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
