The goal is to define a set of clinical pathways for heart failure patients, reflecting the period from prior to admission to the post-discharge period following hospitalisation, under the current system that exists at the two clinical sites [as mentioned previously, the main site is at St Vincent's University Hospital in Dublin, but to ensure generalizability the project team will also carry out similar work Portsmouth Hospital, United Kingdom]. These pathways have been drawn up using the experience of the clinical investigators, using an interactive workshop approach and a pilot study.
