Background. Increasing antimicrobial resistance is a major threat to public health.
Antimicrobial stewardship programs (ASPs) have shown to reduce antimicrobial utilization and resistance, improve patient outcomes, and decrease healthcare-associated
infections. Most ASPs target antimicrobial use in the acute care setting, however, the
bulk of antimicrobial prescribing occurs at ambulatory care sites making these a critical
target for ASPs. We describe a baseline needs assessment for antimicrobial stewardship
efforts focused on appropriate diagnosis and prescribing for urinary tract infections
(UTIs) at ambulatory care sites.
Methods. A retrospective cohort study was conducted of adult patients treated at
three ambulatory care sites providing express care between 1 January 2014 and 30 September 2014 to assess guideline-concordant prescribing (GCP) of empiric therapy for
UTIs. Patients were eligible for inclusion if they had a diagnosis of dysuria, pyuria,
cystitis, pyelonephritis or asymptomatic bacteriuria. Patients were excluded if they
were pregnant, neutropenic, or had a history of renal transplant. Data collected included patient and diagnostic characteristics, appropriateness of therapy, and patient outcomes including office revisits within 30 days and adverse effects. Therapy was
considered GCP if it met national and local health system guidelines for empiric therapy based on drug selection, dose, and duration of therapy.
Results. A total of 1838 patients were eligible for the study; 388 patients were randomly selected for inclusion. Patients were mostly female (91.2%) with an average age
of 50 ± 18 years. Three hundred seventy-six patients (96.9%) had a dipstick urinalysis
performed in the outpatient office while 249 (64.2%) had a urine culture performed.
Escherichia coli was the most commonly identified organism, n = 109 (43.7%), whereas
95 patients (38.1%) had a negative culture. Two hundred ninety-four (75.8%) patients
received antimicrobial therapy. Ciprofloxacin was the most commonly prescribed antibiotic (33.3%), followed by sulfamethoxazole/trimethoprim (29.4%), and nitrofurantoin (12.9%). Total GCP was achieved in only 28.6% (n = 111) of cases with only 31%
of patient receiving the most appropriate drug.
Conclusion. This study supports the need for outpatient ASP interventions targeting appropriate UTI diagnosis and prescribing.
