Violence, dissatisfaction and rapid tranquillisation in psychiatric intensive care

We examined the associations of violence, patient dissatisfaction and occurrence of rapid tranquillisation in psychiatric intensive care, using an on-line nurse-based computerised database over a two-year period. Non-Caucasians were over-represented in violent incidents with physical threat, and previous forensic history was associated with more violent means of attack. Dissatisfaction related to non-understandable provocation and the total number of violent incidents. There was no correlation between rapid tranquillisations or side-effects and dissatisfaction. Remedial action and education in the psychiatric intensive care unit may reduce violence, and better prescribing habits, avoiding anti-psychotic polypharmacy in rapid tranquillisation, should be encouraged.
