Wearable AF Screening Algorithms Face Stricter Real-World Study Framework
Regulatory draft requires real-world false positive rates and follow-up cost reporting; smaller vendors concerned about compliance burden.
Wearable atrial fibrillation screening algorithms face stricter regulatory requirements, with real-world data becoming a new threshold.
Draft Requirements
1. Real-World False Positive Rate
Definition: Proportion of algorithm-predicted AF that was actually sinus rhythm
Reporting content:
- Median false positive rate and percentiles (50%/75%/90%)
- Follow-up confirmation rate
- Follow-up examination cost percentiles
2. Follow-up Cost Assessment
Cost components:
- ECG re-examination fees
- 24-hour Holter monitoring
- Doctor consultation fees
- Patient transportation and time costs
Industry Reactions
Large Enterprises
Large medical device companies have health economics teams ready.
Small/Medium Vendor Concerns
- Broken data chains: Historical data not systematically collected
- High follow-up costs: Active follow-up requires dedicated staff
- Indication contraction: May be required to restrict applicable populations
