| OBJECTIVE: Correlate the evolution of the resistance of Staphylococcus aureus collected from healthcare workers with the local consumption of antibiotics. MATERIAN AND METHODS: Open prospective research.Study Site. General Reference Hospital with 200 beds in a 700,000 inhabitant region, in Ponta Grossa, Paraná, Brazil. RESULTS: Two collections (samples) of Staphylococcus aureus isolates were obtained from healthcare-workers during an approximate four-year interval. Samples 1 (n= 200) and 2 (n= 270) had this bacterium in 63 (32%) and 90 (33%) of the patients, respectively. At the same time, the annual consumption of antibiotics in DDD/1,000 patient-days was determined. The variation of resistance was significantly smaller (m.s.d.=12.11) for gentamycin... |
