Consent- Prospective service user participants will be approached by their nurses. Consent to participation will be obtained by a qualified member of staff who is aware of the Mental Capacity Act 2005. For those without capacity to consent, as this is not a CTIMP, their consultees will be approached for advice regarding involvement. For many participants the consultee is a relative in regular contact; however, some service users have no regular visitors, and rely on professional support. Information sheets (in English and Welsh) and verbal information will be offered and potential participants will be given at least a week to decide whether to be observed or interviewed. Residents (or their family or consultees) to be observed will be asked to sign consent to non-participant observation and review of case notes.
