CA-UTI: Confirming diagnosis, monitoring, prophylaxis
PEARL: CA-UTI is defined as the presence of a urinary catheter for >48 hours, presence of signs or symptoms compatible with UTI, absence of other infectious source, and significant bacteriuria with one or more species
Monitoring:
- Patients should improve in 48-72 hours.
- Failure to improve should prompt evaluation for complicating factors (obstruction, instrumentation, impaired voiding, metabolic abnormalities, immunocompromised states)
- Consider further evaluation such as CT A/P or renal US to rule out or evaluate for perinephric abscess
- Deescalate/narrow antibiotics based on susceptibilities from urine culture
Prophylaxis (IDSA 2009 CA-UTI Guidelines: 29-38):
- Best prophylaxis is removing catheter (if possible). In general, condom > indwelling; intermittent catheterization > indwelling; suprapubic > indwelling in short term (insufficient in long term); suprapubic vs intermittent unclear
- Systemic antibiotics should not be routinely used to due acquired resistance
- Methenamine salt should not be routinely used other than catheters for <1 week
- Cranberry should not be routinely used in neurogenic bladder, insufficient data for other catheter groups
- Meatal care is not recommended
- Cath irrigation with antimicrobials or normal saline should not be routinely used
