Abstract
OBJECTIVES: To investigate the number of different drugs prescribed per dispensing unit and to analyse the influence of practice characteristics on this number. DESIGN: Register analysis based on the Odense Pharmacoepidemiological Database (OPED). SETTING: General practices in the County of Funen, Demnark. SUBJECTS: 173 general practices (99 single-handed and 74 group practices). MAIN OUTCOME MEASURES: Number of different drugs prescribed per dispensing unit. RESULTS: The number of different drugs prescribed per dispensing unit varied nearly fourfold (range 102-381) and four practice characteristics were able to predict 74% of this variation. Practices with several doctors, a high number of patients listed per doctor, a high percentage of elderly individuals, and a heavy workload showed the highest number of different drugs prescribed. CONCLUSION: As the quality of drug prescribing is associated with the use of a limited number of drugs, it is suggested that GPs should agree on a formulary containing the most essential drugs in primary health care.
