To investigate the variation in prescribing among general practices by examining the contribution to this variation of fundholding, training status, partnership status, and the level of deprivation in the practice population and to investigate the extent to which fundholding has been responsible for any changes in prescribing.
Design-Analysis of prescribing data (PACT) for the years 1990-1 (before fundholding) and 1993-4 (after fundholding).
Use of multiple linear regressions to investigate the variation among practices in total prescribing costs (net ingredient cost per prescribing unit), prescribing volume (items per 1000 prescribing units), and mean cost per item in each of the two years and also the change in these variables between years.
The models developed explained the variation in cost per item (43% of variation explained for 1990-1,38% for 1993-4) and prescribing volume (34% for 1990-1,38% for 1993-4) better than the variation in total prescribing costs (3% for 1990-1,7% for 1993-4).
The models developed to explain the change in these variables between years did not explain more than 10% of the variation.
Most of the explained variation in the change in total prescribing costs was accounted for by fundholding.
Of the £3.71 saved by first wave fundholders compared with non-fundholders £3.57 was attributable to fundholding alone. (...)
