The Question

Chronic diseases (diabetes, heart failure, COPD, CKD) account for 74% of global deaths and consume ~86% of US healthcare spending (and a substantial majority of healthcare spending in high-income countries more broadly). Traditional management relies on periodic clinic visits โ€” snapshots of health status separated by weeks or months. Wearable sensors and remote patient monitoring (RPM) promise continuous, real-time physiological data streams that could detect deterioration before symptoms appear and enable proactive intervention. But does continuous monitoring actually improve clinical outcomes, or does it merely generate data that overwhelms clinicians and creates false alarms?

Landscape

Ghadi et al. (2025) reviewed the integration of wearable technology with AI for remote patient care. Their analysis identifies key barriers to adoptionโ€”data privacy constraints, EHR integration challenges, digital literacy gaps, and data overloadโ€”and proposes AI-driven solutions including federated learning (for privacy-preserving model training across institutions) and deep learning frameworks (for intelligent alerting that filters clinically actionable signals from raw sensor streams). The core argument is that moving from "data transmission" to "intelligent alerting" is necessary to address alert fatigue and make RPM clinically sustainable.

Deng et al. (2025) reviewed digital health specifically for chronic kidney disease (CKD), where eGFR decline is gradual and often asymptomatic until advanced stages. They documented how wearable biosensors (continuous blood pressure monitors, hydration sensors) combined with mobile health apps and AI decision support can detect CKD progression earlier than quarterly lab visits, potentially slowing decline through timely medication adjustment.

Stradford et al. (2024) describe the WEAR study protocolโ€”a prospective observational study combining wearable activity trackers with electronic patient-reported outcomes (ePROs) in rheumatoid arthritis patients initiating upadacitinib or adalimumab. The study is designed to test whether objective activity data from wearables adds information beyond self-reported disease activity scores; results are forthcoming as data collection completes.

Daich Varela et al. (2024) extended RPM to ophthalmology, reviewing home-based monitoring devices for retinal diseases. For conditions like diabetic retinopathy and age-related macular degeneration, where visual function changes can be detected before irreversible damage occurs, home monitoring enables earlier treatment initiation.

Open Questions

  • Clinical outcome evidence: Most RPM studies measure process outcomes (hospitalisation rates, time to detection). Do they improve hard outcomes (mortality, disability-free survival)?
  • Health equity: Wearable RPM requires smartphones, internet access, and digital literacy. How should health systems ensure equitable access?
  • Data governance: Continuous health monitoring generates vast personal datasets. Who owns this data, and how should it be protected against commercial exploitation?
  • Reimbursement models: Healthcare payers are slowly adopting RPM reimbursement codes, but coverage varies widely. Can standardised cost-effectiveness evidence accelerate adoption?
