Definition: UTI in a patient with indwelling foley catheter or within 48hrs of removal
Most common nosocomial infection
Bacteriuria and pyuria are very common in catheterized patients:
Symptoms/signs must be present to diagnose CAUTI
Fever/chills, flank pain/CVA tenderness, acute hematuria, pelvic/suprapubic pain, or systemic symptoms/sepsis without another cause.
Absence of pyuria is helpful to rule out the diagnosis.
If no signs/symptoms of UTI, refer to Asymptomatic Bacteriuria
Proper collection of urine cultures in catheterized patients increases the diagnostic accuracy:
How to collect urine cultures in catheterized patients
The catheter is removed and a midstream specimen obtained, or the catheter is replaced and sample sent from the fresh catheter.
Organisms are similar to other UTI (Enterobacteriaceae, Enterococci), but E. coli represents less and there is an increased proportion of Pseudomonas, drug resistant organisms, Staphylococci, and Candida.
