Fluoroquinolone Resistance Score


The score predicts probability of fluoroquinolone-resistant gram-negative bacilli in patients with bloodstream infections (BSI) and complicated urinary tract infections (cUTI).

It is particularly useful in patients with gram-negative BSI who have severe β-lactam allergy and in patients with acute pyelonephritis who do not otherwise require hospitalization.

Fluoroquinolones are not recommended for acute cystitis.
