Reducing overprescribing of antibiotics for suspected urinary tract infections in a health sciences campus student health service.

Recommendations for the management of women with suspected uncomplicated lower urinary tract infections (UTIs) include presumptive antibiotics with or without obtaining a urine culture (UCx). However, with increasing antibiotic resistance, efforts to decrease antibiotic usage are vital. Therefore, the objective of this study was to determine if the presumptive treatment of women with suspected uncomplicated UTIs is contributing to unnecessary antibiotic usage. We retrospectively reviewed all nonpregnant female patients presenting to our student health services clinic with UTI symptoms from December 2016 to May 2017 who had UCx sent. Clinical information, symptoms, office urine dip, and UCx results were reviewed. Patients with positive and negative UCx were compared. A total of 67 patients were included for analysis. Presenting symptoms included dysuria (59/60, 98%), frequency (41/45, 91%), and urgency (27/27, 100%). Office urine dip was performed on 33 of 67 (49%) patients. Dips were positive for leukocytes (88%), blood (79%), and nitrites (18%). All patients in the study were prescribed antibiotics, most commonly nitrofurantoin (82%). Culture results were negative in 29 of 67 (43%). There were no significant differences in duration of symptoms, presenting symptoms, or urine dip results between patients with a negative UCx and those with a positive UCx. In our study, we found a significant negative UCx rate in women with symptoms of uncomplicated UTI, representing a cohort of patients who were exposed to antibiotics unnecessarily. In addition, we found no difference in presenting symptoms or urine dip results to help distinguish patients with a positive UCx.
