Urinary Tract Infections (UTI)
Top Ten Myths Regarding the Diagnosis and Treatment
Lucas Schulz, PHARMD; Robert J. Hoffman, MD; Jeffrey Pothof, MD; Barry Fox, MD
J Emerg Med. 2016;51(1):25-30.

Selon les auteurs les bactériuries asymptomatiques sont banales dans tous les groupes d'âge et sont trop souvent surtraitée. Un diagnostic d'infection urinaire (UTI) devrait être basé sur une combinaison des symptômes cliniques et des résultats de laboratoire. Ces deux volets permettront aux prescripteurs de démasquer les pièges courants dans le diagnostic des infections urinaires.

Background:
Urinary tract infections (UTI) are the most common type of infection in the United States. A Centers for Disease Control and Prevention report in March 2014 regarding antibiotic use in hospitals reported "UTI" treatment was avoidable at least 39% of the time. The accurate diagnosis and treatment of UTI plays an important role in cost-effective medical care and appropriate antimicrobial utilization.

Objective:
We summarize the most common misperceptions of UTI that result in extraneous testing and excessive antimicrobial treatment. We present 10 myths associated with the diagnosis and treatment of UTI and succinctly review the literature pertaining to each myth. We explore the myths associated with pyuria, asymptomatic bacteriuria, candiduria, and the elderly and catheterized patients. We attempt to give guidance for clinicians facing these clinical scenarios.

Discussion:
From our ambulatory, emergency department, and hospital experiences, patients often have urine cultures ordered without an appropriate indication, or receive unnecessary antibiotic therapy due to over-interpretation of the urinalysis.

Conclusions:
Asymptomatic bacteriuria is common in all age groups and is frequently over-treated. A UTI diagnosis should be based on a combination of clinical symptoms with supportive laboratory information. This review will assist providers in navigating common pitfalls in the diagnosis of UTI.
