158. Impact of Fluoroquinolone Cascade Reporting of Urine Samples on Antibiotic Prescribing Rates in a Network of Urgent Care Clinics

Results Immediately following the change to cascade reporting, FQ prescribing decreased by 38% (incidence rate ratio [IRR] 1.38; 95% confidence interval [CI] 0.50-0.77 p < 0.0001) and no change in trend was subsequently seen (IRR 1.01, 95% CI 0.98-1.04; p =0.59) (Figure 1).Cephalexin prescribing did not immediately change following the intervention (IRR 1.20, 95% CI 1.00-1.33; p =0.05) but subsequently showed a trend towards increase use (IRR 1.04, 95% CI 1.02-1.06; p < 0.0001) (Figure 1).
