6 Background: Pathogenesis of CAUTI

Background: Pathogenesis of CAUTI

* Source of microorganisms may be endogenous (meatal, rectal, or vaginal colonization) or exogenous, usually via contaminated hands of healthcare personnel during catheter insertion or manipulation of the collecting system

7 Background: Pathogenesis of CAUTI

Background: Pathogenesis of CAUTI

Formation of biofilms by urinary pathogens common on the surfaces of catheters and collecting systems Bacteria within biofilms resistant to antimicrobials and host defenses Some novel strategies in CAUTI prevention have targeted biofilms

8 CAUTI Definitions

CAUTI Definitions

Surveillance definitions for UTI recently modified in NHSN (as of Jan 2009) Please refer to NHSN Patient Safety Manual http://www.cdc.gov/nhsn/library.html Count symptomatic UTI (SUTI) only, not asymptomatic bacteriuria (ASB) Exception is “ABUTI” (asymptomatic bacteremic UTI) – see NHSN manual above Clinical significance of ASB unclear Should not screen for or treat ASB routinely, except in certain clinical situations Most literature to date includes ASB in outcomes, making interpretation of data difficult

9 Evidence-based Risk Factors for CAUTI

10 Prevention Strategies

Prevention Strategies

Supplemental Strategies Some scientific evidence Variable levels of feasibility

Core Strategies High levels of scientific evidence Demonstrated feasibility

*The Collaborative should at a minimum include core prevention strategies. Supplemental prevention strategies also may be used. Most core and supplemental strategies are based on HICPAC guidelines. Strategies that are not included in HICPAC guidelines will be noted by an asterisk (*) after the strategy. HICPAC guidelines may be found at www.cdc.gov/hicpac

11 Core Prevention Strategies (all Category IB)

http://www.cdc.gov/hicpac/cauti/001_cauti.html

16 Core Prevention Strategies Specific recommendations (IB)

Core Prevention Strategies Specific recommendations (IB)

Following aseptic insertion, maintain a closed drainage system If breaks in aseptic technique, disconnection, or leakage occur, replace catheter and collecting system using aseptic technique and sterile equipment Consider systems with preconnected, sealed catheter-tubing junctions (II) Obtain urine samples aseptically

http://www.cdc.gov/hicpac/cauti/001_cauti.html

17 Core Prevention Strategies Specific recommendations (IB)

Core Prevention Strategies Specific recommendations (IB)

Maintain unobstructed urine flow Keep catheter and collecting tube free from kinking Keep collecting bag below level of bladder at all times (do not rest bag on floor) Empty collecting bag regularly using a separate, clean container for each patient. Ensure drainage spigot does not contact nonsterile container.

18 Core Prevention Strategies: Specific recommendations (IB)

Core Prevention Strategies: Specific recommendations (IB)

Implement quality improvement programs to enhance appropriate use of indwelling catheters and reduce risk of CAUTI Examples: Alerts or reminders Stop orders Protocols for nurse-directed removal of unnecessary catheters Guidelines/algorithms for appropriate perioperative catheter management

http://www.cdc.gov/hicpac/cauti/001_cauti.html

19 Supplemental Prevention Strategies: Examples

Supplemental Prevention Strategies: Examples

Consideration of alternatives to indwelling urinary catheterization (II) Use of portable ultrasound devices for assessing urine volume to reduce unnecessary catheterizations (II) Use of antimicrobial/antiseptic-impregnated catheters (IB, after first implementing core recommendations for use, insertion, and maintenance ) The following slides will provide further details on supplemental strategies…

20 Supplemental Prevention Strategies: Alternatives to Indwelling

Supplemental Prevention Strategies: Alternatives to Indwelling

Catheterization

Intermittent catheterization – consider for: Patients requiring chronic urinary drainage for neurogenic bladder Spinal cord injury Children with myelomeningocele Postoperative patients with urinary retention May be used in combination with bladder ultrasound scanners External (i.e., condom) catheters – consider for: Cooperative male patients without obstruction or urinary retention

http://www.cdc.gov/hicpac/cauti/001_cauti.html

21 Supplemental Prevention Strategies: Bladder Ultrasound Scanners

Supplemental Prevention Strategies: Bladder Ultrasound Scanners

Rationale: fewer catheterizations = lower risk of UTI 2 studies of adults with neurogenic bladder undergoing intermittent catheterization Inpatient rehabilitation centers Fewer catheterizations per day but no reported differences in UTI Significant study limitations: likely underpowered; UTIs undefined

comprehensive strategy First implement core recommendations for use, insertion, and maintenance Ensure compliance with core recommendations

Supplemental Prevention Strategies: Antimicrobial/Antiseptic-Impregnated Urinary Catheters

http://www.cdc.gov/hicpac/cauti/001_cauti.html

23 Supplemental Prevention Strategies: Silver-Coated Catheters

Supplemental Prevention Strategies: Silver-Coated Catheters

Decreased risk of bacteriuria compared to standard latex catheters in a meta-analysis of RCTs Significant differences for silver alloy but not silver oxide-coated catheters Effect greater for patients catheterized < 1 week Mixed results in observational studies in hospitalized patients Most used laboratory-based outcomes (bacteriuria) 1 positive, 2 negative, 5 inconclusive

http://www.cdc.gov/hicpac/cauti/001_cauti.html

24 Supplemental Prevention Strategies: Silver-Coated Catheters

Supplemental Prevention Strategies: Silver-Coated Catheters

One study in a burn referral center found a decrease in SUTI Pre-intervention catheters standard latex Intervention group had silver-impregnated catheters and had new catheters inserted on admission under nonemergent sterile conditions “The improved results in time period 2 are probably due to the combination of these two changes in therapy.”

30 Measurement Considerations

Measurement Considerations

May need to consider alternative metrics (in addition to standard rates by device days) to demonstrate a reduction in CAUTIs if catheter days (denominators) greatly reduced with interventions Alternative denominator examples: Patient days on unit Numbers of catheters inserted

31 Evaluation Considerations

Evaluation Considerations

Assess baseline policies and procedures Areas to consider Surveillance Prevention strategies Measurement Coordinator should track new policies/practices implemented during collaboration
