[Initial management of the patients with psychiatric involvement in hospital emergency departments: a systematic review].

This article is a systematic review of studies that have investigated the initial management of patients with psychiatric conditions in hospital emergencies services in order to establish practical recommendations. A systematic review of the literature was carried out, consisting of studies published from 2010 to 2020, available in any language, consulting Cochrane Library Plus, PubMed, IBECS, LILACS and MEDLINE. The quality of the studies included in this review was assessed by the AMSTAR2 tool and the FCL 3.0 platform, together with the PRISMA statement. Results from the eleven papers selected showed that improvements in staff training, available resources, appropriate use of restraint and appropriate choice of medication can help to improve the care of patients with mental pathology in hospital emergency services. The same management for any other patient is recommended. However, if the patient is agitated or uncooperative, verbal, pharmacological and/or mechanical restraint (in this order) may be necessary.
