Catheter Associated
Urinary Tract Infection
(CAUTI)
Diagnostic Test Results:
≥100,000 CFUs/mL of
≥1 species of bacteria
Signs & Symptoms:
Systemic or non-specific,
such as fever,
c
rigors/
chills, or new onset,
clear-cut delirium with
no other identified
cause, OR Localizing
to genito-urinary tract
such as suprapubic or
costovertebral angle
tenderness OR Acute
pain, swelling, or
tenderness of the testes,
epididymis, or prostate (in
men) OR If a catheter was
removed in the previous
48 hours, presence of
signs and symptoms
that localizes to the
genito-urinary tract such
as urgency, frequency,
dysuria, gross hematuria,
suprapubic tenderness
or costovertebral angle
tenderness
If prompt
resolution of
symptoms, 7 days
For patients with
a delayed response
to treatment,
10–14 days of
antibiotics is
reasonable
It is important to note that a CAUTI
can be present with lower colony
counts of bacteria (100–1000 CFUs/
mL), but most persons with CAUTI
have colony counts ≥100,000 CFUs/
mL.
CAUTI can lead to complications
like prostatitis, epididymitis and
epididymo-orchitis in males, so
presence of acute pain, swelling, or
tenderness of the testes, epididymis,
or prostate should trigger evaluation
for these diagnoses.
Presence of costovertebral angle
tenderness on exam suggests renal
involvement.
