[A model for monitoring drug prescribing in general practice]

When prescribing drugs, general practitioners at the same should satisfy the requirements of medical science and their vocation, being aware of their task of a rational disposal of the limited resources allocated for health care. The aim of the paper was to determine the characteristics of monitoring model for drug prescription in general practice, taking into consideration the characteristics of the population, morbidity, drugs and physicians. A prospective monitoring of prescribing drug during one month was carried out in six doctor's offices of general practice/family medicine at the Dugave-Travno Health Station of the Novi Zagreb Health Center. In processing data on patients, drugs and physicians the following were used: distribution description and analysis, pair's tests and General Factorial Anova. Out of 3397 patients who visited the above mentioned doctor's offices, 2320 (68.3%) patients were prescribed 4796 prescriptions--an average of 2.07 prescriptions per patient (from 2.00 to 2.42). The total cost of drug prescription was 360,117.33 kunas (from 43,632 to 77,910 kunas). The number of prescriptions and the cost of prescribed drugs increased significantly in terms of statistics with the age of patients (Spearman's correlation coefficient 0.2263; p < 0.001). By General Factorial Anova statistically significant difference was determined in the cost variable among the physicians with the impact of covariate age and number of prescriptions. Professionally, the most appropriate and most rational prescribing was observed among physicians who had the highest educational level and the longest experience in practice. In order to analyze and assess the appropriatness of drug prescription in general practice, the first essential step is to collect data on what is being prescribed, for whom it is being prescribed, and to enable access to data for physicians. This paper has indicated some of the characteristics of a monitoring model for drug prescription in general practice. Formulation and implementation of this model would considerably promote the professional appropriateness and rationality in drug prescription in general practice.
