AbstractThe prevalence of violent behaviour within acute psychiatric services is about 10%.AimTo identify the pharmacological management of acutely disturbed behaviour in patients requiring rapid tranquillisation (RT) on a psychiatric intensive care unit (PICU). Socio-demographic and clinical characteristics were also identified in these patients.Method and objectivesA retrospective cohort examination was carried out of 24 patients receiving RT, average age of 38.8 years (7 women and 17 men), admitted to the PICU between 1 January 2011 and 31 December 2011. Patient records and hospital incident reporting system were used to obtain relevant data for analysis.ResultsThe majority of patients were detained (95%); suffering from schizophrenia (45.8%); bipolar disorder (25%) and substance misuse disorders (12.5%). Verbal aggression (58.3%) and threatening behaviour (29.2%) were the most common factors leading to RT. Fourteen patients (58.3%) were medicated with a combination of haloperidol and lorazepam; nine (37.5%) with zuclopenthixol acetate only; and one (4.2%) with a combination of zuclopenthixol and promethazine.ConclusionHaloperidol in combination with lorazepam was the most common medication utilised for RT. Nevertheless, zuclopenthixol acetate alone, or combined with other drugs, was used in over 40% of cases. This finding is in considerable variation with recommended guidelines.
