Determinants of prescribing patterns for type II diabetes at Primary Care Trust level.
OBJECTIVE
To estimate the effect of demography, deprivation and ethnicity on variations in prescribing of oral antidiabetics at the Primary Care Trust level.


METHODS
Cross-sectional survey.


METHODS
All Primary Care Trusts in England.


METHODS
Percentage of variance explained.


RESULTS
A model using measures of demography, ethnicity, deprivation and use of thiazolidinediones explained 59% of the variation in cost per registered patient although individual variables explained far less.


CONCLUSIONS
This study shows the importance of using a multivariate approach in modelling the drivers of cost. The high use of thiazolidinediones is of concern in the light of NICE guidance.
