A local resistance proportion

A fictional hospital summarizes two hundred eligible urinary E. coli isolates from a defined period. Eighty are resistant to the proposed empirical fluoroquinolone. The report states its sampling rules and is not a culture result for the current patient. A clinician wants to ignore the summary and prescribe the drug before susceptibilities return. Another clinician notes that the patient is stable but needs an effective initial strategy selected through the appropriate local pathway. The case does not provide allergies, pregnancy status or a full list of suitable alternatives, so the task is to interpret the data rather than name a universal replacement drug.
