Not every patient who is hospitalized needs a Foley catheter. The HICPAC/CDC guidelines, adopted by most facilities, limit catheter use to specific clinical indications. Inserting a catheter for convenience ("so we can measure urine accurately" without a clinical need for precise measurement, or "because the patient is incontinent") is not appropriate and increases CAUTI risk.
| Appropriate Indication | Clinical Example |
|---|---|
| Urinary retention (acute) | Patient unable to void despite urge; bladder scan showing residual above 300–400 mL; obstructive uropathy |
| Accurate measurement of urine output in critically ill patients | ICU patients on vasopressors; hemodynamic instability requiring hour-by-hour urine output monitoring; acute kidney injury management |
| Peri-operative use in select surgical procedures | Prolonged procedures (expected >2 hours); urological procedures; procedures requiring intraoperative or postoperative urine monitoring |
| Open sacral or perineal wounds in incontinent patients | Stage 3/4 pressure injury near the perineum that would be contaminated by urinary incontinence; facilitating wound healing |
| Comfort care/palliative care | End-of-life patients for whom catheter placement improves comfort and avoids painful transfers to bedpan |
| Bladder irrigation per physician order | Post-urological surgery continuous bladder irrigation; gross hematuria with clot management |
| Bundle Element | Practice |
|---|---|
| Insert only when indicated | Verify appropriate clinical indication before inserting; question orders for urinary catheters that don't meet criteria; propose alternatives |
| Sterile technique on insertion | Strict sterile field, sterile gloves, sterile drape, sterile catheter, sterile lubricant; no breaks in technique — if the sterile field is breached, start over with new supplies |
| Maintain a closed drainage system | Never disconnect the catheter from the drainage bag unless clinically necessary; closed drainage system prevents ascent of organisms; use a sampling port for urine specimens (not by disconnecting the system) |
| Keep the drainage bag below bladder level | Drainage bag must always be below the patient's bladder to prevent backflow of contaminated urine; secure tubing to avoid dependent loops that pool urine |
| Maintain urethral hygiene | Cleanse the urethral meatus and catheter at the urethral junction daily (or per institutional policy) with mild soap and water; do not use antiseptic solutions or antibiotic cream routinely on the catheter |
| Remove catheter as soon as possible | Reassess catheter necessity daily; prompt removal when clinical indication resolves; nurse-initiated removal protocols (where policy allows) reduce catheter-days significantly |
| Hand hygiene | Before and after any catheter manipulation; before and after emptying the drainage bag |
| Catheter care during patient movement | When ambulating, repositioning, or transferring: drain the bag before ambulation; keep bag below bladder level continuously; avoid kinking the tubing |
Normal urine output: 0.5 mL/kg/hour in adults; for a 70 kg patient, this is approximately 35 mL/hour. A general clinical threshold: urine output below 30 mL/hour for 2 consecutive hours requires provider notification in most acute care settings.
Expected urine output findings and clinical interpretation:
Dark, concentrated urine (amber/brown) = dehydration, decreased renal perfusion; verify fluid status and assess for renal function changes. Bright red blood in urine = hematuria — assess for trauma, catheter trauma, urological pathology; notify provider. Cloudy, foul-smelling urine = possible UTI — notify provider; obtain culture per order before starting antibiotics. Urine output suddenly stops (anuria) — check for catheter obstruction first (irrigate per order if indicated); if catheter patent but output absent, notify provider for renal evaluation.
CAUTI is clinically defined as a urinary tract infection in a patient who has or has had an indwelling urinary catheter within 48 hours. Clinical signs include: fever (above 38°C or 100.4°F) without another identified source, suprapubic tenderness, costovertebral angle (CVA) tenderness (flank pain), worsening urinary symptoms in patients who have had the catheter removed.
Bacteriuria (bacteria in urine) alone, without symptoms, is NOT CAUTI and typically does not require antibiotic treatment — asymptomatic bacteriuria in catheterized patients is very common and treatment increases antibiotic resistance without clinical benefit. Treatment is indicated for symptomatic CAUTI per provider order.
Catheter removal requires: deflating the balloon completely before withdrawal (aspirate all sterile water from the balloon port — typically 10 mL); withdraw the catheter gently; document the time of removal. After removal, monitor for first void: patient should void within 4–6 hours of catheter removal; document time and volume of first void. If the patient has not voided within 4–6 hours and is uncomfortable, perform a bladder scan to assess for post-void residual — if above 300–400 mL, notify provider and discuss re-catheterization vs. straight catheterization.
