Low-quality. Evidence suggests no benefits of antimicrobial prophylaxis in patients undergoing short-term catheterization.This was based on heterogeneous results for SUTI and bacteriuria / unspecified UTI and no adverse events related to antimicrobial.Lack of consistency in specific factors,such as patient protection,antimicrobial agents,timing of administration,and duration of follow-up,didnot allow for a summary of evidence of the effect of antimicrobial prophylaxis on CAUTI in patients undergoing short-term catheterization.Only two studies evaluated adverse events related to antimicrobial.
