About

Between 2013-2014, our study network of U.S. emergency departments, EMERGEncy ID NET, found that the rate of fluoroquinolone-resistant E. coli was 11.7% among all patients, 6.3% in uncomplicated and 19.9% in complicated. ESBL-producing Enterobacteriaceae were found in 7.7% of all cases, 2.6% in uncomplicated and 12.2% in complicated. More recently, Enterobactericeae and gram-negative non fermenting bacteria have started to show resistance to carbapenems (CREs and CR-NF). Patients hospitalized with UTI and urosepsis represent a higher risk population for infections due to multi-drug resistant bacteria and experience serious adverse outcomes, including death. EMERGEncy ID NET will conduct a study to determine the prevalence of ESBL-producing, CREs and CR-NFs among this high risk population of patients admitted for UTI from U.S. emergency departments.

Enrollment: 801 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Age greater than or equal to 18 years;
2. Admitted to the hospital through the ED;
3. Primary reason for admission is treatment of UTI with or without sepsis (i.e., ED diagnosis of UTI and/or sepsis); and
4. Provide verbal or written consent to participate in the study or if patient is unable to provide consent (e.g., altered mental status), consent obtained from a legal authorized representative.

Exclusion criteria

• patients will be later excluded if :

  1. they are unable to provide a urine specimen for culture; or
  2. their urine culture yields no growth or is contaminated (see definition of positive urine culture below). Note: If participant's urine culture is contaminated but their blood culture is positive for a uropathogen, they will not be excluded.
