Abstract
BACKGROUND: Prescribing is the most common therapeutic intervention in primary care, and there is substantial variation in prescribing practice across England. We investigate broad patterns of prescribing across Health Authorities in England, concentrating on ethnically diverse populations. METHODS: Initially we examined the association between a number of prescribing indicators from the Prescribing Support Unit Prescribing Toolkit and 'Needs Profiles'. We then considered whether the observed patterns of prescribing were appropriate, that is, could be largely explained by variations in the prevalence of a medical condition for which the corresponding group of drugs would be prescribed. RESULTS: The volume and cost of prescribing was generally lower in more ethnically diverse Health Authority populations when compared with more elderly or deprived populations. There was a significant negative association between ethnic composition and net-ingredient-cost per patient of cardiovascular drugs, but this disappeared upon adjusting for mortality from coronary heart disease. CONCLUSIONS: The volume and cost of prescribing was generally lower in more ethnically diverse Health Authority populations relative to other high-need population profiles. Further work on this subject matter is merited, particularly if individual level data is available.
