the use of antibiotics among outpatients in the different health areas of
Methods: Study of the prescription of antibiotics in the health areas
of Aragon in 2008. Data were extracted from theAragon Pharmaceutical
Consumption Database, a complete register of all dispensed prescriptions.
Prescription rates per 1000 individuals adjusted by sex and age
were calculated using a direct and indirect standardization method. The
subgroups utilization were calculated in Defined Daily Dose per 1000
inhabitants per day (DID). In the variation analysis were used: extremal
quotient (EQ), coefficient of variation (CV), weighted coefficient of
variation (CVw).
Results: The adjusted rate of antibiotic varied between 279,8 and
382 per 1000 inhabitants, showing a CVw=0,12. The utilization rate in
women was 364.9 per 1,000 and in men 300.0 per 1,000. Cephalosporins
have a EQ=2,42 and CVw=0,37; and quinolones have EQ=1,84 and
Conclusions: The utilization rate was higher in women than men.
