[Antimicrobial prescription in family health units in Southern Brazil].
This paper describes antimicrobial prescription, clinical indications, and seasonal characteristics in primary health care. We performed a cross-sectional study in family health units in Bagé, Rio Grande do Sul State, Brazil, in July 2005 and January 2006. All medical prescriptions (n = 2,877) were analyzed, and the prevalence rates for antimicrobial prescription in winter and summer were 30.4% (95%CI: 28.5-32.4) and 21% (95%CI: 19.1-22.9), respectively. The most frequently prescribed antimicrobials were amoxicillin and sulfamethoxazole-trimethoprim. The main clinical indications for antimicrobial prescription were non-specific upper respiratory tract infections (22.5%), throat infections (20.8%), urinary tract infections (13.3%), otitis (8.5%), and sinusitis (7.5%). We observed differences between summer and winter in prescriptions for the same diseases. Seasonal differences between treatment profiles for the same diseases show the absence of a consistent antimicrobial prescription pattern in primary health care, contrary to World Health Organization guidelines, which advocate the establishment of protocols for antimicrobial use at all levels of care, as a strategy to prevent inadequate usage and the occurrence of strains that are resistant to available antimicrobials.
