Using NHSN Definitions for Surveillance: Urinary Tract Infection (UTI)

STANLEY OSTRAWSKI, MS, RN, MT(ASCP), CICInfection Preventionist Consultant

Objectives• Explain how to calculate a CAUTI rate• Explain how to complete NHSN UTI forms using CDC

definitions and protocols• Apply case definitions of Urinary Catheter-

associated infections to case studies

Introduction – Urinary Tract Infections and Indwelling Urinary Catheters

• The urinary tract is the most common site of HAI

• Almost all UTIs are directly related to catheterization of the urinary tract

• CAUTI can lead to complications such as pyelonephritis or bacteremia,

CAUTI –Terms and Definitions

Use CDC Definitions for the following: – CAUTI– Indwelling catheter– SUTI– ABUTI– OUTI

Definition: CAUTI

CAUTI is a urinary tract infection (UTI) that occurs in a patient who had an indwelling urinary catheter in place within the 48-hour period before the onset of the UTI

NOTE: There is no minimum period of time that the catheter must be in

place in order for the UTI to be considered catheter-associated

Definition: Indwelling Catheter

• A drainage tube that is inserted into the urinary bladder through the urethra, is left in place, and is connected to a closed collection system.– Also called a Foley catheter– Does not include straight in and

out catheters– Does not include suprapubic or

nephrostomy catheters

Specimen CollectionUrine specimens for culture should be processed as soon as possible, preferably within 1 to 2 hours. If urine specimens cannot be processed within 30 minutes of collection, they should be refrigerated, or inoculated into primary isolation medium before transport, or transported in an appropriate urine preservative. Refrigerated specimens should be cultured within 24 hours.
