Clinical Scenario A
A 35 y/o G3P3 female calls the clinic with a complaint of burning with urination and increased frequency. She denies any fever, chills or new onset back pain. She notes that this “feels like a UTI.” The patient speaks with the nurse over the phone, and the call is routed to the physician. The physician reviews her records, notes she is otherwise healthy, without any recent UTIs and prescribes a 5-day course of nitrofurantoin over the phone with instructions to call if her symptoms persist or worsen. The patient agrees and confirms understanding of the plan.
Clinical Scenario B
A 35 y/o G3P3 female calls the clinic with a complaint of burning with urination and increased frequency. She denies any fever, chills or new onset back pain. She notes that this “feels like a UTI.” The patient speaks with the nurse over the phone, and the nurse asks the patient to come to the clinic. On arrival in the clinic, the patient is asked for a clean-catch urine sample. The sample is tested by dipstick, and is found to have 3+ leukocytes, positive for nitrites, and otherwise negative. The patient waits 15 minutes to see the physician. Meanwhile, given that the urine was positive by dipstick, the urine sample is sent for urinalysis and urine culture, per clinic policy. The patient then sees the physician who prescribes the patient a 5-day course of nitrofurantoin. She is instructed to call if her symptoms persist or worsen. The patient is sent home after 30 minutes. The physician calls the patient 4 days later to let her know her culture returned E.coli positive and is susceptible to nitrofurantoin. The patient states she is feeling much better.
- Was a urine culture indicated in this patient?
- Can an uncomplicated UTI be treated over the phone?

The patient presented in the case above has acute uncomplicated cystitis, defined by the symptoms presented. Treatment is a course of nitrofurantoin. Further laboratory testing does not give information that would change initial management. A urine culture is only needed if the patient’s symptoms are not relieved by treatment or worsened despite treatment. Furthermore, the patient does not even need to be seen in the office; if she had complained of fever, chills, back pain or other symptoms suggestive of a more systemic infection (i.e. pyelonephritis), an office visit would be warranted, with urine culture and susceptibility testing done. Pregnancy is another indication for being seen in the office. Studies have shown that urine culture does not decrease follow-up clinic visits. There is no need for a medical visit or labs when treating an episode of acute uncomplicated cystitis.
