A survey of prescribing of psychotropic drugs in a Birmingham psychiatric hospital.

Of 603 patients receiving in-patient or day-patient psychiatric care, one-sixth were taking no psychotropic drugs, but nearly 50% of those receiving medication had a combination of two or more such drugs. Hypnotics and minor tranquillisers were frequently prescribed together with neuroleptics and antidepressants. One-third of all patients receiving neuroleptics received a combination of oral and depot preparations, while half of all patients on neuroleptics were prescribed anti-parkinsonian drugs. One-fifth of patients treated with neuroleptics had a diagnosis other than schizophrenia, and one-third of patients treated with antidepressants had a diagnosis other than affective disorder. A comparison of our findings with those from Oxford show some significant differences, particularly in the use of depot, oral, of combined neuroleptic drugs. An analysis of prescribing could be a useful part of self-audit for hospitals.
