Cefuroxime Resistance in Pyelonephritis

Plain-language summary

Resistance to empirical antibiotic treatment has resulted in increased mortality and morbidity in serious infections caused by certain common resistant pathogens in the community. The risk for increased mortality has been also the motivation for recent guidelines that suggest early empirical antimicrobial treatment with broad spectrum antibiotics within a few hours of suspecting sepsis, regardless of the potential microorganism or infection focus. Resistance to second-generation cephalosporins among patients with community-acquired urinary tract infection by E. coli has exceeded 20% in an increasing number of institutions and communities, without being clear about the impact of such resistance on the effectiveness of treatment. This is especially important in urinary infections, since, in general, mortality is very low. We expect to establish if there is a relationship between inappropriate empirical therapy and morbidity (in terms of length of stay or readmission) among hospitalized patients with pyelonephritis treated with empirical cefuroxime therapy to help to define the need for a change in the current guidelines. These guidelines will have application not only in Colombia, but also in other countries in Latin America or other countries that still use this empirical therapy. It will also define the need for use of broader spectrum antibiotics in this clinical scenario.
