NHS mental health services' policies on leave for detained patients in England and Wales: A national audit.

Unlabelled: WHAT IS KNOWN ON THE SUBJECT?: 'Leave' is a common occurrence for patients detained in mental health settings. The term covers multiple scenarios, for example short periods to get off the ward through to extended periods at home prior to discharge. Despite the frequency and importance of leave, there is very little research about how it is implemented and whether, and in what circumstances, it is effective.

Effectiveness and experiences of mental health nurses in cases of medical emergency and severe physiological deterioration: A systematic review.

Background: From a baseline of near zero, there has in recent years been a growing number of empirical studies related to mental health nurses' delivery of healthcare for severely physically deteriorating patients or in medical emergency situations. To date, this evidence-base has not been systematically identified, appraised, and integrated.

Objectives: To systematically identify, appraise and synthesise the available empirical evidence about mental health nurses, medical emergencies, and the severely physiologically deteriorating patient.

Systematic review of therapeutic leave in inpatient mental health services.

Aim: To identify, critically evaluate, and synthesise the empirical evidence about therapeutic leave from mental health inpatient settings.

Background: "Leave" occurs when a mental health inpatient exits the hospital ward with the appropriate authorisation alone, or accompanied by staff, family, or friends. Limited research has previously addressed therapeutic as opposed to unauthorised leave, and the evidence-base has not been systematically evaluated.
