Abstract
Complicated urinary tract infections (cUTIs) are a major cause of hospital admissions and are associated with significant morbidity and health care costs. Patients presenting with a suspected UTI should be screened for the presence of complicating factors, such as anatomic and functional abnormalities of the genitourinary tract. In the setting of cUTIs, the etiology and susceptibility of the causative organism is not predictable; therefore, when infection is suspected, patients should undergo a urinalysis in addition to culture and sensitivity testing. Although not warranted in all cases of complicated pyelonephritis, blood cultures are appropriate in some clinical settings. With the increased prevalence of antimicrobial resistance, and the lack of well-designed clinical trials, treatment of cUTIs can be challenging for clinicians. Although resistant organisms are not always implicated as the causative agent, all patients with cUTIs should be assessed for predisposing risk factors. Consideration of an optimal antimicrobial agent should be based on local resistance patterns, patient-specific factors, including anatomic site of infection and severity of disease, pharmacokinetic and pharmacodynamic principles, and cost. Resistance to first-line antimicrobial agents, including fluoroquinolones, has become increasingly common in Escherichia coli. Fluoroquinolones should not be used as a first-line option for empiric treatment of serious cUTIs, especially when patients exhibit risk factors for harboring a resistant organism, such as previous or recent use of fluoroquinolones. Fluoroquinolones, trimethoprim-sulfamethoxazole, and nitrofurantoin are still appropriate empiric options for mild lower cUTIs. However, empiric treatment for serious cUTIs, where risk factors for resistant organisms exist, should include broad-spectrum antibiotics such as carbapenems or piperacillin-tazobactam. Once organisms and susceptibilities are identified, treatment should be targeted accordingly. Nitrofurantoin and fosfomycin have limited utility in the setting of cUTIs and should be reserved as alternative treatment options for lower cUTIs following confirmation of the causative organism. Aminoglycosides, tigecycline, and polymyxins can be used for the treatment of serious cUTIs when first-line options are deemed to be inappropriate or patients fail therapy. The duration of treatment for cUTIs has not been well established; however, treatment durations can range from 1 to 4 weeks based on the clinical situation.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
