Patients will consent to undertake qualitative research to evaluate the process of community stratification. A purposeful sample of patients completing the community biomarkers pathway will be invited to participate in qualitative follow up of their experiences of the pathway and any subsequent lifestyle change. A researcher, trained in qualitative research methods, will perform a semi-structured interview, which will assess any lifestyle changes occurring following liver pathway stratification. Specifically, changes in alcohol consumption, diet and exercise will be explored and evaluated, with assessment of the relationship to liver pathway stratification (both investigation results and lifestyle advice offered during the pathway). Interviews will performed either face-to-face, in which case this will be performed at the Nottingham Digestive Diseases Biomedical Research Unit, or over the telephone - in all cases voice recording will occur to allow analysis of information provided. An example interview proforma to be utilized for these qualitative interviews has been provided separately.
