Comparison of data quality and monitoring completion rates between clinic and self-applied electrocardiogram (ECG) patches
Authors' conclusion
Self-applied ECG patches were returned at a lower rate and had a statistically lower percentage of analyzable time than clinic-applied patches. However, there were no differences between groups in mean percentages of prescribed wear time, and mean percentages of analyzable time were >95% in all groups.
Study context
- Population
- Patients prescribed an ECG patch
- Participants
- 29,093 ECG patch prescriptions
- Exposure
- Self-applied vs clinic-applied ECG patches, pre-COVID and COVID years
- Outcome
- ECG patch return rate, mean % analyzable time, mean % prescribed wear time
Main finding
As reported in the abstract
ECG patch return rate
P < 0.001
Observational data: associations, not effects.

|---|---|---|---|---|
| Mean % analyzable time (returned patches)COVID self-applied vs clinic-applied groups | 96.6% (SD 7.4%) | 96.6% (SD 6.6%) | 95.9% (SD 8.2%) | P < 0.001 |

- Mean % analyzable time (returned patches): 28,048 returned patches (17.5% self-applied)
