Underprescribing of Clozapine and Unexplained Variation in Use Across Hospitals and Regions in the Canadian Province of Qu茅bec
Clinical guidelines recommend a trial of clozapine for schizophrenia patients who are refractory to other antipsychotics; its benefits for this population, including a reduction in suicide rates, have been documented in numerous studies.聽聽 This paper uses Qu茅bec government administrative data (RAMQ and Med-Echo) to show that, in 2004, fewer than 7% of people with schizophrenia in Qu茅bec were receiving clozapine.聽 A rate of 12% would be considered closer to optimal.聽 Moreover, rates of clozapine prescribing vary greatly across hospitals, with 8% of 61 hospitals in the province showing no patients at all on clozapine.聽 It is doubtful if the situation has changed much since then.聽 Several specific measures, including increasing access to community-based teams such as those following the Assertive Community Treatment model (which facilitate the regular blood monitoring required with clozapine) and the setting up of clozapine clinics in each hospital, and of a provincial clozapine resource center such as one that used to exist in British Columbia, would likely help to increase access to this medication for patients who would benefit from it.聽
