Abstract
BACKGROUND: There is no conclusive evidence that either high doses or combinations of antipsychotics are more effective than standard doses or monotherapy alone. Nonetheless, prescription of both remains prevalent in the UK. In 2006 the South London and Maudsley NHS Foundation Trust (SLAM) participated in a national survey of prescription of antipsychotic medications, organized by the Prescribing Observatory for Mental Health. Over half of the patients on SLAM inpatient or psychiatric intensive care units were prescribed a high-dose antipsychotic or a combination of antipsychotics. Prescribing high-dose antipsychotics and polypharmacy in SLAM was found to be among the highest in the UK. AIM: To assess the impact of a 6-year quality improvement programme aimed at reducing the rates of prescribing high-dose antipsychotics and polypharmacy on SLAM inpatients and psychiatric intensive care units. RESULTS: There was a significant reduction between baseline and final survey in the rates of prescription of both high-dose antipsychotics and polypharmacy on SLAM inpatients and intensive care units (58% versus 10% p < 0.0001 and 57% versus 16%, p < 0.0001 respectively). The proportion of patients at final survey prescribed a high-dose antipsychotic and a combination was substantially lower in SLAM than in the national sample (10% versus 28%, p < 0.0001 and 16% versus 38%, p < 0.0001 respectively). CLINICAL IMPLICATIONS: A sustained change in the prescribing culture of an organization can be achieved through a targeted improvement programme.
