Months of May: Mental health presentations and the impact of a psychiatric emergency care centre on an inner-city emergency department.

OBJECTIVES: The impact of psychiatric emergency care centres (PECCs) on ED mental health (MH) presentations has not been presented. We aim to compare demographics, diagnosis and admission frequency of patients presenting to an inner-city ED with MH complaints, before and for several years after the opening of a PECC. METHODS: We collected ED patient data for the first 200 'mental health' presentations during the month of May in 2005-2007, and 2015-2017. Data included demographics, diagnosis, post-ED disposition, length of stay in ED, use of the Mental Health Act, and the presence of expressed suicidality and psychotic disorders. RESULTS: The days to reach 200 MH presentations decreased from 43 days in 2005 to 17 days in 2017. The mean length of ED stay approximately halved with PECC's introduction, with 20% of patients being admitted to PECC. Prior to PECC, 75% of suicidal patients were discharged from ED; after the opening of PECC, 84% of patients expressing suicidality were admitted to PECC; and 73% of patients admitted with psychotic symptoms went to the acute psychiatric ward. CONCLUSIONS: Between 2005 and 2017, MH presentations to ED became significantly more frequent. The opening of PECC reduced length of stay in ED and provided an admission trajectory for patients expressing suicidality, while retaining the pathway to the acute psychiatric ward for those patients presenting with psychosis.
