AI-enabled ECG potassium monitoring for people with stage 3b–5 chronic kidney disease

Monitoring Hyperkalemia Using Point-of-care AI-enabled ECG Device Among Patients With Chronic Kidney Disease Stages 3b-5 to Reduce Rate of Hyperkalemia - a Practical Randomized Clinical Trial

Not applicable Interventional Peking University First Hospital · NCT06901960

What this trial studies

In an outpatient setting, participants with moderate-to-advanced chronic kidney disease will use a point-of-care AI-enhanced ECG device at least twice weekly to estimate their serum potassium category over six months. The device classifies potassium into four bands (<5.0, 5.0–<5.5, 5.5–<6.0, and ≥6.0 mmol/L) and delivers health-education prompts when readings are abnormal. Persistent abnormal readings trigger alerts advising participants to visit their nephrology clinic. The study will measure whether this frequent, patient-led monitoring reduces the occurrence of serum potassium ≥5.0 mmol/L and will track participant adherence to the monitoring regimen.

Who should consider this trial

Good fit: Ideal candidates are adults with CKD stages 3b–5 (eGFR 10–<45 mL/min/1.73 m2) who have regular visits at the participating sites and are willing and able to use a mobile ECG device, and who are not on kidney replacement therapy.

Not a fit: Patients already on dialysis or expected to start kidney replacement within six months, those with implanted pacemakers, or those unable or unwilling to use the device are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, this approach could reduce episodes of high potassium and prompt earlier clinic care to prevent complications from hyperkalemia.

How similar studies have performed: Prior studies have demonstrated that AI applied to ECGs can estimate serum potassium with reasonable accuracy, but deploying a patient-facing home AI-ECG program to reduce hyperkalemia events remains largely untested in routine clinical practice.
