Economic and clinical impact of diagnostic sensitivity for the use of insertable cardiac monitors to detect atrial fibrillation in cryptogenic stroke patients in the United Kingdom

Insertable cardiac monitors (ICMs) are recommended by international clinical guidelines for prolonged cardiac monitoring in patients with cryptogenic stroke (CS). However, only LINQ ICM has been recognised as cost-effective by the National Institute for Health and Care Excellence (NICE) for this indication, as other ICMs may vary in diagnostic yield. It is unclear how this might impact patient outcomes and cost-effectiveness. This study aims to evaluate the clinical and economic impacts of diffe
