A Decision Support Alert for Promoting Prophylactic Laxative Use with Clozapine.

We investigated the effectiveness of a decision support alert to improve prophylactic laxative use with clozapine in hospital. Prescribing data for first clozapine and laxative prescriptions were extracted and linked. Proportions of first clozapine prescriptions for which a laxative was co-prescribed within 24 hours was compared before and after alert implementation. The alert was associated with increased and earlier laxative co-prescribing.
