Each site will identify 12 patients from their practice who will be asked to participate in the study. With their consent, the patient's contact details will be passed to the researcher who will contact them over the phone and inform them of what the study entails. Prior to this phone call, the patients will have received a written information and a consent sheet through email, post or in person at their practice. The signed consent sheet can be returned the in same way. Once recruited, the participants will be randomly allocated to either the intervention group (24 patients) or the control group (24 patients).
