[Surveillance of antibiotic utilization and bacterial resistance profiles in tertiary level hospitals in Mexico City]

Abstract

Objective: To identify the levels of antibiotic utilization and the resistance profiles of nosocomial bacteria, as well as the strategies to diminish resistance to antibiotics.

Materials and methods: A descriptive, retrospective (1994-1995) study was conducted in six tertiary level hospitals in Mexico City.

Results: A total of 86% antibiotic resistance was observed in these hospitals. The overall consumption of antibiotics per hospital ranged between 44 and 195 Defined Daily Doses/100 day-beds.

Conclusions: We identified the components to frame an integral surveillance system aimed at improving the use of antibiotics and the quality of the bacterial resistance assessment in these hospitals.
