OBJECTIVE: Antimicrobials are used interchangeably in medical practice, contributing to the emergence of resistant microbial strains. METHODS: This study describes the antimicrobial audit performed by forecasting analysis of medical records of 846 patients at the Hospital Santa Cruz, Santa Cruz do Sul - Rio Grande do Sul - Brazil. RESULTS: Of the patients studied, 134 (15.8%) received antimicrobials. The audit was conducted interactively, with intervention and discussion with the prescriber. Considering the presumptive diagnosis and prescribed drug, it was verified that 74.6% of patients on antimicrobials received what was considered the first choice treatment. Inadequate antimicrobial agent for clinical diagnosis (5.2%) and lack of adjustment for renal function (43.7%) were the most frequent errors. CONCLUSION: A strategic plan aimed at the rational use of antimicrobials based on educational and interventionist practices can help the infection control professional to adjust the routines to improve healthcare quality.
