Data collection: Ward level data Mean number of inpatient days, mean number of inpatient days with compulsory care and mean number of involuntary treatment interventions (involuntary injections, medical restraint) for pre- and post intervention periods will be derived from the clinic's administrative database. Overall care burden is measured at each ward with an instrument developed by the Psychosis Clinic for quality monitoring. The instrument includes objective items (number of admissions and discharges, number of involuntary treatments during the shift etc), followed by a subjective item on the overall level of burden perceived during the shift. The form is filled out by one staff member on each ward once a day according to clinical routine.
