Authorised leave from hospital, especially for those who are detained, can be used to check readiness for discharge and to maintain social connections that support a patient's recovery journey. Leave therefore often involves friends and family, or 'carers'. However, carer involvement in planning leave is limited, and carers struggle with feeling unsupported during the leave.</p><p><strong>Aims: </strong>This study aimed to explore carers' and mental health practitioners' subjective experiences of leave in the context of implementing a set of practice guidelines for involving carers in planning and undertaking leave from hospital.</p><p><strong>Method: </strong>Nine wards in six National Health Service trusts were recruited to implement the guidelines.
