Supermarket/Hypermarket Opportunistic Screening for Atrial Fibrillation (SHOPS-AF): A Mixed Methods Feasibility Study...

Area of Science:

• Cardiology
• Public Health
• Medical Technology

Background:

• Atrial fibrillation (AF) is a common heart arrhythmia and a major risk factor for ischemic stroke.
• Oral anticoagulation significantly reduces stroke risk in AF patients.
• Hand-held electrocardiogram (ECG) devices offer potential for routine AF screening.

Purpose of the Study:

• To evaluate the effectiveness of a hand-held ECG sensor (MyDiagnostick) for AF screening when integrated into supermarket trolley handles.
• To assess the feasibility of embedding AF detection technology into everyday objects for opportunistic screening.

Main Methods:

• A mixed-methods approach involving a two-phase study.
• Phase 1: Quantitative assessment with 2000 participants using MyDiagnostick-equipped trolleys in supermarkets.
• Phase 2: Qualitative interviews with pharmacists and store managers to explore staff perceptions.

Main Results:

• The study will determine the sensitivity, specificity, and predictive values of the MyDiagnostick sensor for AF detection.
• Data will be collected on participant engagement and the practicalities of in-store screening.
• Pharmacist and manager feedback will provide insights into the implementation of this screening strategy.

Conclusions:

• This feasibility study is designed to inform a larger, definitive trial on AF screening using integrated technology.
• The findings will guide the development of innovative, routine screening programs for atrial fibrillation.
