Prescribing data, metrics or supporting resources
The selection of metrics to support key therapeutic topics is overseen by the NHS England Medicines Optimisation Intelligence Group, and work is ongoing in this area. At this point, the following resources have been identified by this group to support this topic.
The National dementia and antipsychotic prescribing audit from 2012 suggests that there has been an encouraging overall reduction in the proportion of people with dementia being prescribed antipsychotics in recent years. See the National Dementia and Antipsychotic Prescribing Audit for more details.
Based on data from 46% of GP practices across England, the audit found that the number of people newly diagnosed each year with dementia increased by 68% in relative terms from 2006 to 2011. However, there was an absolute decrease of 10.25% in the number of people with dementia receiving prescriptions for antipsychotic medication over that time (from 17.05% in 2006 to 6.80% of people in 2011, a 60% reduction in relative terms). The proportion of people receiving a prescription for an antipsychotic within a year of being diagnosed with dementia also decreased by 9.79% in absolute terms from 2006 to 2011 (from 14.25% to 4.46%, a 69% reduction in relative terms). Nevertheless, although reductions in prescribing rates were seen across all geographical areas of England, there was still considerable variation in the percentage of people diagnosed with dementia prescribed an antipsychotic.
The Prescribing Observatory for Mental Health-UK (POMH-UK) audit, Prescribing antipsychotic medication for people with dementia, suggests that the prevalence of antipsychotic use in mental health trusts or healthcare organisations for behavioural and psychological symptoms of dementia decreased between 2011 and 2012 (by 23%) and this decrease was maintained in 2016 (19% down from 2011).
