Supermarket/hypermarket opportunistic screening for atrial fibrillation (SHOPS-AF) using sensors embedded in the handles of supermarket trolleys: A feasibility study
Authors' conclusion
The study demonstrates that the public will engage with AF screening undertaken as part of their daily routines using hand-held devices.
Study context
- Population
- Supermarket shoppers in four supermarkets in Northwest England203 analysed
- Participants
- 2,155 participants
- Outcome
- AF detection
Methodological detailsobservational, 4 supermarkets
- Observational
- 4 supermarkets
Main finding
As reported in the abstract
- Confirmed or suspected atrial fibrillation (AF)
- 59
- Known AF
- 20
- Previously undiagnosed AF
- 39
- No evidence of AF
- 115
- Non-diagnostic recordings, mainly artefact
- 46
Observational data: associations, not effects.
Further findings
Diagnostic accuracy of the sensor (range across 3 analyses of non-diagnostic ECGs)
- Sensitivity
- 0.70 to 0.93
- Specificity
- 0.15 to 0.97
- PPV
- 0.24 to 0.56
- NPV
- 0.55 to 1.00
- Non-diagnostic ECGs n = 46; analyses excluding them, assuming all AF, assuming all not AF
- Interpret with caution: reference standard on 1934 participants imperfect
Newly diagnosed AF by sex and age
- Men and older participants significantly more likely to have newly diagnosed AF
