Staff at iRhythm (the company of produces and provides the Zio Patch) who analyse the information contained in the patch will not be able to identify you. However, other members of staff working on the AMALFI study at Oxford can access personal data that directly identifies you, such as your name, address and date of birth. 

Information collected about you during the study may also be looked at, in confidence, by authorised individuals from the University of Oxford and regulatory authorities, to check that the study is being carried out correctly.

In addition, AMALFI has been invited to take part in an international collaboration that aims to better understand the impact of the patch on clinical events, such as strokes. The collaboration will pull together and analyse data from all similar atrial fibrillation screening trials that have taken place in different countries.  The University of Copenhagen, in Denmark has created a secure database specifically for this purpose. AMALFI plans to provide the collaboration with a limited subset of the data that has been collected as part of the study. This will not include any information that might identify you. You can opt out of having your data shared  by calling us on 0808 164 50 80, or via email on
