This prospective, multicenter, comparative cohort observational study is to determine if Guidance® UTI pathway compared to traditional diagnostic pathways reduces the rates of empiric antibiotic therapy, adverse events, and improves therapeutic accuracy of treatment

We propose to conduct a multicenter, comparative cohort observational study to determine whether the use of Guidance® UTI Clinical Pathway compared with current traditional pathways for urine testing reduces the rates of empiric antibiotic therapy and improves therapeutic accuracy of treatment. Comparative outpatient Urology and urogynecology office cohorts will be allocated at an uneven 2:1 allocation ratio. Regardless of arm assignment, all outpatient offices have the option to order ANY diagnostic test for suspected UTI, this includes urine cultures and/or other molecular testing methods including Guidance® UTI. If a provider in the Guidance Clinical Pathway arm decides to order urine cultures instead of using the Guidance® UTI Clinical Pathway, those results will also be reported to the site lead, though TAT may take up to 72 hours to result per standard culture protocols. We will be observing the practice's implementation of the Clinical Pathway and reporting infrastructure to provide rapid, centralized reporting to the ordering provider, allowing for efficient treatment. Guidance® UTI is currently widely available, and all participating outpatient offices (regardless of arm) will have the option to order this test.

Inclusion Criteria:

• Able to provide verbal informed consent

• Male and Female Subjects > 18 years of age may participate with no predetermined quotas or ratios for gender participation (Group 2).

• Male and Female Subjects > 18 and older may participate with no predetermined quotas or ratios for gender participation (Group 1).

• A history of complicated UTI (cUTI)**

• Must present at the time of enrollment with clinically suspected active UTI (any LUTS)

• Management requires microbial identification and sensitivities of urine

  **Definition of cUTI- A UTI is considered complicated when the individual has one or more risk factors that predispose to higher treatment failure and poor outcomes.6 These poor outcomes include persistence of UTI, increasing severity, or occurrence of complications such as urosepsis, recurrence, and perinephric abscess. Although the definition of cUTI may vary among current medical bodies and organizations, for this study, we define examples of cUTIs to include:

• UTIs in the elderly population due to increased chances of comorbidities and immune compromised state,

• Recurrent UTIs2, which is defined as the occurrence of ⩾2 symptomatic episodes within 6 months or ⩾3 symptomatic episodes within 12 months

• UTI in patients with anatomic or functional pathology affecting the urinary tract, such as an obstruction, hydronephrosis, renal tract calculi, or colovesical fistula

• UTIs occurring due to an immune compromised state, such as steroid use, post chemotherapy, diabetes, and HIV, and transplant recipients

• UTIs caused by atypical microorganisms or multi-drug resistant microorganisms. Typical UTI-causing microorganisms include E. coli, P. aeruginosa, several species within the Enterobacteriaceae family (Proteus and Klebsiella), and a few Gram- positive bacteria, such as Staphylococcus saprophyticus and Enterococcus faecalis, as well as fungi, such as Candida sp.7,5

• UTI in male: UTIs occurring despite the presence of anatomical protective measures as part of the male urinary tract anatomy are by definition cUTI,

• UTI in patients with history of radiotherapy to the abdomen or pelvis,

• UTIs occurring after instrumentation, nephrostomy tubes, ureteric stents, suprapubic tubes, or Foley catheters

• UTI in patients with the history of recurrent UTI,

• UTIs in patients with impaired renal function,

• UTIs following prostatectomies or radiotherapy

Exclusion Criteria:

• Patients with history of chronic pelvic pain syndrome/interstitial cystitis (Excluded in GROUP 2 only)
• Patients that are receiving radiation therapy in the pelvic region
• Patients with history of unstable, untreated, or are failing treatment for overactive bladder (either neurogenic or non-neurogenic)
• Patients with history of bladder malignancy in the past 3 years
• Patients that have been treated with chemotherapy in the past 3 years
• Inability to independently provide symptom data
• Patient must have email access if they choose to complete surveys online.
• Pregnancy
• Incarceration

Individuals >18 years requiring evaluation for suspected urinary tract infection in the urology or urogynecology practice.
