Safety check

Required: confirm no red flags, or select every red flag present

No red flags identified — clear to continue

Before confirming no red flags

• Asymptomatic bacteriuria should NOT be treated — especially in older adults, where positive dipstick without symptoms is common and not infection.
• Tighten exclusions: male patient, pregnancy, pyelonephritis symptoms (flank pain, fever, vomiting), recurrent, indwelling catheter, recent antibiotic course, known resistance.
• TMP-SMX: screen for hyperkalemia risk (ACEi/ARB/spironolactone, CKD) and warfarin interaction (INR spike) before prescribing.
• Reassess at 48–72 h; if no improvement, switch agent or refer.

Treatment

Finish the assessment first. Treatment opens when steps 1 to 3 are complete.

Follow-up

Sets the reminder and the documents

Phone or in-person check-in 2-3 days after starting treatment to confirm symptom resolution and identify treatment failure.

Review after

Use the pathway guidance and your assessment to choose the interval. This choice updates the documents; add a reminder to see it in your follow-up list.
