Quality of cardiovascular drugs prescribing in Croatia 2003-2008.

The aim of the study was to determine cardiovascular drugs utilization and quality of prescribing in Croatia from 2003 to 2008. Data on the outpatient utilization of cardiovascular drugs in Croatia were collected during 2003-2008. Data on the size and number of packages, were obtained from Croatian institute for Health Insurance (CIHI). Based on the data obtained, the numbers of DDD and DDD per 1000 inhabitants per day (DDD/1000/day) were calculated for all cardiovascular drugs. Quality of drugs prescribing was assessing using Drug Utilization 90% (DU90%) method. Renin-angiotensin system agents showed highest share in the utilization of group C drugs, followed by calcium channel blockers. These two groups of drugs accounted for half of the overall cardiovascular drug utilization. Greatest changes were observed in the groups of renin-angiotensin system agents and hypolipemics. The number of drugs within DU90% segment increased between 2003 and 2008. In the same period Cost/DDD decreased.
