Reducing alert fatigue in remote patient monitoring by 73%
Threshold-only RPM alerts bury care teams in false positives; adding per-patient baselines and trend analysis cut non-actionable alerts by 73% without missing deterioration.

Why threshold alerts fail
A single blood-pressure cut-off treats a patient whose normal systolic is 100 the same as one whose normal is 150. It fires constantly for one and misses meaningful change in the other.
Care coordinators receiving dozens of non-actionable alerts a day learn to dismiss them, which is how a real event gets missed.
The trend-analysis approach
Establish a rolling baseline per patient per metric. Alert on deviation from that baseline and on the rate of change, not on a population threshold.
Cross-reference metrics — a weight trend plus a heart-rate trend plus reduced activity is a stronger signal than any one reading. Then route by acuity: dashboard flag, coordinator task, or immediate call.
Frequently asked questions
- What causes alert fatigue in remote patient monitoring?
- Population-level thresholds that ignore each patient's individual baseline, producing a high volume of non-actionable alerts that care teams learn to ignore.
- How do you reduce RPM false positives without missing real events?
- Use per-patient rolling baselines and trend detection instead of static thresholds, combine multiple metrics into one signal, and route alerts by acuity.
- Does RPM trend analysis support CPT billing?
- Yes. The platform still records the device-supplied data and interactive-communication time needed for CPT 99453, 99454 and 99457 documentation.
