The uncomplicated, symptomatic lower urinary tract infection (UTI; acute bacterial cystitis) is a common and costly reason for physician referral and hospital visits. In the year 2000, 8.27 million physician visits for UTIs were reported (1.41 million men, 6.86 million women), with an estimated cost of $3.5 billion for evaluation and treatment.1 UTIs are more prevalent in women; of the 429,000 hospital stays due to UTIs, approximately 75% are attributed to women.1


The most common causative pathogen in uncomplicated, symptomatic lower UTIs is Escherichia coli, which accounts for 75% to 90% of infections. Staphylococcus saprophyticus follows, causing 5% to 15% of UTIs. The remaining infections are caused by enterococci, Klebsiella species, and Proteus mirabilis.2,3

Signs and Symptoms

The bladder is the most common site of lower UTIs. Common signs and symptoms of acute, uncomplicated lower UTIs in nonpregnant women include dysuria, frequency, or urgency. 2-4 Urine also may appear dark, cloudy, or pinktinged. Acute cystitis is more common in young, sexually active women with a history of UTIs.2,3 Complicated upper UTIs (eg, pyelonephritis) occur in the kidneys, are associated with systemic symptoms (eg, patients with fever, chills, flank pain), and are found more often in high-risk populations (eg, patients with diabetes, pregnancy, immunosuppression, previous pyelonephritis, symptoms lasting >14 days, or structural abnormalities of the urinary tract).2,3

Pharmacist?s Role in the Management of Acute, Uncomplicated UTIs in Women

  • Recommend the appropriate empiric antimicrobial agent based on local E coli resistance (antibiogram) and the patient?s drug allergies, renal function, and insurance coverage
  • Monitor the duration of antimicrobial therapy for patient safety and cost-effectiveness
  • Recommend the conversion from intravenous antimicrobial therapy to an appropriate oral product in the hospitalized patient who has improved and is tolerating orals
  • Provide counseling on antimicrobial dosing and administration, duration of therapy, and adverse drug events
