Urinary Tract Infection
Antibiotic selection for each population presented depends on susceptibility of prior urinary isolates, patient circumstances (such as allergies or expected tolerability, history of prior antimicrobial use), potential toxicities, interactions, local community resistance patterns, availability, and cost.
A positive urinalysis (presence of WBC (>10/hpf), nitrite+ and/or LE>trace) alone cannot be used to rule in UTI in patients with non-specific symptoms due to the prevalence of asymptomatic bacteriuria.
A change in mental status alone is not sufficient to diagnose UTI in patients with pyuria and/or bacteriuria. Due to the risks of unnecessary antibiotic treatment, routine UA is not recommended without clear signs and symptoms of infection in hemodynamically stable patients.
