Förskrivningsmönster och kostnader för läkemedel undersöktes vid Växsjös åtta apotek från 1990 till 1996. Allmänläkarnas läkemedelsförskrivning var mindre kostsam och har bättre följsamhet till läkemedelskommitténs rekommendationer än förskrivningen från andra läkarkategorier. En orsak till dessa skillnader kan ha varit lokala utbildningsaktiviteter kring en rationell läkemedelsförskrivning.

BACKGROUND: In southern Sweden, many general practitioners (GPs) participate in an extensive postgraduate drug education programme, and many health centres are also fed back crude local drug statistics from pharmacists in the area. Private physicians and hospital physicians have not participated in these programmes. 

OBJECTIVE: The drug prescribing habits and costs of GPs, hospital physicians and private physicians were compared. 

METHODS: Each March, from 1990 to 1997, all prescriptions dispensed at the eight pharmacies in Vaxjo, a city and municipality in southern Sweden, were registered, specifying drug(s) prescribed, price, patient's age, sex and area of residence, and prescriber's place of work and category. 

RESULTS: Overall, the costs of prescribed drugs increased with time, even in 1997 when the prescribing volume was reduced due to changes in the reimbursement system. The cost increase was caused by increased prescribing of newer, more expensive drug alternatives. However, within each of the eleven major drug groups, the drugs prescribed by GPs were less expensive than those prescribed by hospital physicians and, particularly, private physicians. Moreover, even though GPs prescribed more and a wider range of drugs, they also had a higher degree of adherence to the recommendations by the formulary committee. 

CONCLUSION: GPs prescribed less expensive drugs and had a higher degree of adherence to the recommendations by the formulary committee than other categories of physicians. One reason for these differences may be that the GPs participated in regional and local educational activities aimed at the rationalisation of drug prescribing.
