Current Clinical Applications of Wearable Technology

Wearables now support a wide range of Patient Care scenarios. Below are core domains where they are already reshaping practice.

1. Continuous Vital Sign and Cardiac Rhythm Monitoring

Wearables have transformed how vital signs and cardiac rhythms are monitored:

• Smartwatches and Fitness Bands
  Many now measure:

  • Heart rate and heart rate variability (HRV)
  • Respiratory rate (derived)
  • Oxygen saturation (SpO₂)
  • Skin temperature trends

  Some devices can detect irregular rhythms and prompt ECG recordings to screen for atrial fibrillation (AF). These detections can be transmitted to clinicians for confirmation and follow-up.

• Medical-Grade Cardiac Patches and Monitors
  Devices like ambulatory ECG patches (e.g., Zio Patch) provide:

  • Long-term rhythm monitoring (up to 14+ days)
  • Higher signal quality than consumer devices
  • Algorithm-based arrhythmia detection

  For cardiology and primary care, such devices support AF detection, syncope workups, and evaluation of palpitations with greater convenience and compliance than traditional Holter monitors.

Clinical Pearl: As a clinician, you’ll increasingly see patients presenting with smartwatch alerts or rhythm strips. Understanding how to interpret these in context—and when to escalate to formal cardiac testing—is becoming a practical skill set.

2. Fitness, Activity, and Sleep Tracking

The wellness segment has important clinical implications:

• Physical Activity Monitoring

  • Daily step counts, activity time, intensity zones
  • Sedentary time and movement breaks
    Data from devices like Fitbit, Garmin, and Apple Watch can be integrated into care plans for obesity, cardiovascular disease, diabetes, and post-operative recovery.

• Sleep Tracking
  Wearables estimate:

  • Total sleep time
  • Sleep stages (light, deep, REM)
  • Sleep interruptions and efficiency

  While not equivalent to polysomnography, these trends can flag potential sleep disorders, inform behavioral counseling, and track response to interventions (e.g., CBT-I).

Practical Application: Some health systems and insurers are piloting programs where wearables are prescribed or subsidized for high-risk populations to promote lifestyle changes and to track outcomes for value-based care contracts.

3. Chronic Disease Management and Digital Therapeutics

Chronic Disease Management is one of the highest-yield use cases for wearables.

• Diabetes and Continuous Glucose Monitoring (CGM)
  Devices like Dexcom or FreeStyle Libre:

  • Provide near real-time glucose trends
  • Offer alerts for hypo- and hyperglycemia
  • Integrate with smartphone apps and insulin pumps
    Evidence shows that CGM improves time-in-range and reduces severe hypoglycemia, especially in type 1 and insulin-treated type 2 diabetes.

• Cardiovascular Disease and Heart Failure
  Wearables can:

  • Track resting heart rate and HRV as markers of autonomic function
  • Estimate cardiorespiratory fitness (VO₂ max equivalents)
  • Monitor weight, activity, and sometimes bioimpedance for fluid status
    In heart failure programs, combining wearable data with remote symptom reporting helps detect early decompensation and prevent hospitalizations.

• COPD and Asthma
  Smart inhalers, respiratory wearables, and phone-connected spirometers:

  • Track medication use, technique, adherence
  • Measure peak flow or FEV₁ surrogates
  • Correlate symptoms with triggers (activity, environment)

These systems enable more precise, proactive interventions and can provide objective data for treatment adjustments.

4. Mental Health, Stress, and Behavioral Monitoring

A growing class of wearables focuses on psychological well-being:

• Stress and Mood Indicators
  Devices analyze:

  • Heart rate variability (HRV)
  • Electrodermal activity (skin conductance)
  • Sleep and activity patterns
    to infer stress levels or autonomic imbalance.

• Behavioral Health Support
  Paired apps may:

  • Prompt breathing exercises during periods of increased physiologic stress
  • Nudges for breaks, mindfulness, or physical activity
  • Track mood, energy, and anxiety via symptom logs

While these tools don’t replace formal psychiatric assessment, they can assist early detection and provide objective correlates to patient-reported symptoms.

5. Remote Patient Monitoring (RPM) and Virtual Care

Remote Patient Monitoring has become central since the COVID-19 pandemic:

• Acute and Post-Acute Care at Home
  Wearable devices enable:

  • Post-surgical vital sign monitoring
  • Post-discharge heart failure weight and symptom tracking
  • Home-based COVID-19 or respiratory illness monitoring

• Chronic Care Management Programs
  RPM platforms integrate:

  • Blood pressure cuffs, scales, pulse oximeters, wearables
  • Nurse or care coordinator dashboards
    These allow early outreach when metrics fall outside individualized thresholds.

For clinicians entering practice, RPM offers new models of care delivery and may influence job descriptions, workload, and reimbursement structures.

Clinicians should be prepared to address patient questions about privacy and to work with organizations that implement robust encryption, access controls, and transparent data governance policies.

2. Accuracy, Validation, and Clinical-Grade Performance

Not all wearables are created equal:

• Consumer devices may have variable accuracy (especially at extremes of heart rate, in darker skin tones, or with motion artifact).
• Medical-grade devices undergo regulatory review and clinical validation but may be more expensive or less user-friendly.
• Over-reliance on imperfect metrics can lead to anxiety, over-testing, or false reassurance.

Clinicians should understand the evidence base and limitations of common devices, and integrate wearable data as one component of a broader clinical assessment—not as a standalone diagnostic tool.

3. Data Overload and Workflow Integration

Continuous monitoring can mean continuous data:

• Clinicians risk being overwhelmed if data feeds are not filtered, summarized, and intelligently prioritized.
• Many EHRs still struggle with seamless integration of wearable data into clinician workflows.
• Alert fatigue can become a serious issue if thresholds are poorly set.

A key future competency will be designing and working within systems that optimize signal-to-noise, using dashboards, AI triage, and team-based review workflows.

4. Equity, Digital Literacy, and Patient Compliance

• Not all patients can afford wearables or have smartphones or reliable internet access.
• Differences in digital literacy may exacerbate existing health disparities.
• Long-term adherence may drop due to discomfort, charging requirements, or waning interest.

Health systems and clinicians should consider:

• Subsidized or loaner programs for high-risk patients
• Simple user interfaces and multilingual support
• Education and coaching to build digital confidence

5. Professional Boundaries and Medicolegal Concerns

Continuous connectedness blurs traditional boundaries:

• Expectations around 24/7 monitoring and response must be clearly communicated.
• Liability concerns arise if concerning data is transmitted but not reviewed in a timely way.
• Policies need to define how often data is checked, by whom, and what constitutes a clinically actionable alert.

For new attendings and APPs, it’s essential to understand institutional policies and to advocate for well-defined RPM protocols and documentation standards.
