Protocol · 2026 Edition

A urinalysis interpreter with sex-, pregnancy-, and CKD-aware antibiotic selection.

Paste UA + culture results to autopopulate, or enter values manually. The algorithm classifies the syndrome (contamination · ASB · uncomplicated UTI · complicated UTI · pyelonephritis · acute / chronic prostatitis · CAUTI · urosepsis) and returns first-line, alternative, and avoid-list antibiotics gated by sex, pregnancy trimester, renal function, allergies, and comorbidities. Primary reference: OLOL UTI Guideline v6 (2025) consistent with IDSA. Secondary: IDSA 2010 Uncomplicated · IDSA 2019 ASB · IDSA 2009 CAUTI · AUA 2022 Recurrent UTI · ACOG 2023.

Chart Paste — UA & Culture

Paste the relevant chart text (POCT dipstick, full UA, urine culture w/ susceptibilities). The parser autopopulates the form below and unlocks culture-driven de-escalation.

Patient Profile

Each field shapes the classification and the antibiotic plan. Asymptomatic patients are screened separately from symptomatic ones.

01. Sex at Birth

Female short urethra · pregnancy gate Male UTI is complicated by default

02. Patient Age Group

Child < 13 yr Teen 13–17 Adult 18–64 Geriatric ≥ 65

03. Pregnancy Status (if female of reproductive age)

Not pregnant incl. postmenopausal 1st trimester 0–13 wk 2nd trimester 14–27 wk 3rd trimester ≥ 28 wk

04. Symptom Status

Asymptomatic incidental UA · screening Symptomatic dysuria · urgency · etc.

06. Urinalysis — Dipstick

Leukocyte esterase Nitrite Blood Protein Glucose Ketones pH Specific gravity

07. Urinalysis — Microscopy

WBC / hpf RBC / hpf Bacteria Squamous epithelial cells Casts Yeast

08. Renal Function (CKD Stage)

Stage 1–2 eGFR ≥ 60 Stage 3a/b 30–59 Stage 4 15–29 Stage 5 / dialysis < 15

09. Drug Allergies

Sulfa avoid TMP-SMX PCN — mild (rash) cephalosporins OK PCN — anaphylaxis / SJS avoid β-lactams Fluoroquinolone avoid FQ Nitrofurantoin avoid macrobid Cephalosporin cross-react risk

11. Local Antibiogram (drives empiric ranking)

OLOL 2024 LALK · Urine primary · my org BRG 2023 · Urine 2022 data

Interpretation & Plan

UA classification first, then antibiotic options filtered against sex, pregnancy, renal function, allergies, and comorbidities.
