At discharge one additional interview was conducted with those participants who were studied more closely in order to hold on to their experiences (Table 2).

In addition, to further contextualise and understand the response, a number of additional interviews were then conducted with stakeholders who were not available during the visit and, in some cases, with key experts in a particular field.
