Recruitment and sample
RECRUITMENT
During the process evaluation, health and social care stakeholders in each triad where the intervention was delivered, were invited to take part in a semistructured interview at the end of each 6 month phase: PIPs n=23 (2 withdrew and contact details not available), GPs n=25 and CH managers n=38. A reminder invitation email was sent after 2 weeks. CH managers provided recruitment information to staff, residents and relatives. Those interested in participating returned expressions of interest to study researchers. A purposive sampling framework was designed to ensure representation across stakeholder roles, location and phases of the intervention. However, response rates were low and therefore all those replying were invited to interview.
