Nursing interventions to reduce the risk of catheter-associated urinary tract infection. Part 1: Catheter selection.

BACKGROUND: The urinary system is the most common site for all hospital-acquired infections, accounting for approximately 40% of all nosocomial infections. The US Centers for Medicare & Medicaid Services has enacted 2 policies that have focused considerable attention on the optimal use of indwelling catheters in the acute and long-term care settings and the prevention of complications including catheter-associated urinary tract infection (CAUTI). OBJECTIVES: This is the first of a 2-part Evidence-Based Report Card reviewing current evidence pertaining to nursing actions for prevention of CAUTIs in patients with short- and long-term indwelling catheters. Part 1 reviews evidence for materials for catheter construction, including incorporation of antimicrobial substances into the catheter, and selection of catheter size. SEARCH STRATEGY: Nursing actions for prevention of CAUTIs were identified based on search of electronic databases and Web-based search engines for national or international clinical practice guidelines focusing on this topic. Evidence related to 2 common nursing interventions, selection of the material of construction and selection of catheter size, was identified by searching electronic databases MEDLINE, CINAHL, the Cochrane Library, and the ancestry of articles identified in these searches. RESULTS: We found robust evidence supporting insertion of a silver alloy-coated catheter to reduce the risk of CAUTIs for up to 2 weeks in adult patients managed by short-term indwelling catheterization. We also found evidence supporting the insertion of an antibiotic-impregnated catheter for reduction of CAUTI risk for up to 7 days. There was insufficient evidence to determine whether regular use of an antimicrobial catheter reduces the risk of CAUTIs in adults managed with long-term indwelling catheterization. There was insufficient evidence to determine whether selection of a latex catheter, hydrogel-coated latex catheter, silicone-coated latex catheter, or all- silicone catheter influences CAUTI risk. Expert opinion suggests that selection of a smaller French-sized catheter reduces CAUTI risk, but evidence is lacking. IMPLICATIONS FOR PRACTICE: Insertion of an antimicrobial catheter, either silver alloy or antimicrobial coated, is recommended for patients with short-term indwelling catheterization. There is insufficient evidence to recommend their use in patients managed by long-term indwelling catheterization. Selection of smaller French sizes for short- or long-term catheterization is thought to improve comfort and reduce CAUTI risk, but further research is needed to substantiate these best practice recommendations.

Nursing interventions to reduce the risk of catheter-associated urinary tract infection: part 2: staff education, monitoring, and care techniques.

BACKGROUND: The US Centers for Medicare & Medicaid Services has enacted 2 policies that have focused considerable attention on the optimal use of indwelling catheters in the acute and long-term care settings and the prevention of complications including catheter-associated urinary tract infection (CAUTI). OBJECTIVES: This is the second of a 2-part Evidence-Based Report Card reviewing current evidence pertaining to nursing actions for prevention of CAUTI in patients with short- and long-term indwelling catheters. Part 2 reviews multiple interventions for CAUTI prevention including staff education, monitoring of catheter use and CAUTI incidence, insertion technique, urethral meatal care, securement, use of a closed drainage system, bladder irrigation, frequency of catheter change, and antiseptic solutions in the drainage bag. SEARCH STRATEGY: Nursing actions for prevention of CAUTI were identified based on search of electronic databases and Web-based search engines for national or international clinical practice guidelines focusing on this topic. Evidence related to the above nursing interventions was identified by searching electronic databases MEDLINE, CINAHL, the Cochrane Library, the ancestry of articles identified in these searches and Google scholar. RESULTS: Limited evidence suggests that the following interventions reduce the incidence of CAUTI in patients managed by short-term indwelling catheterization: (1) staff education about catheter management, combined with regular monitoring of CAUTI incidence, (2) a facility-wide program to ensure catheterization only when indicated and prompt removal of indwelling catheters, (3) daily cleansing of the urethral meatus using soap and water or perineal cleanser, and (4) maintenance of a closed urinary drainage system. Mixed evidence suggests that use of a preconnected system reduces inadvertent interruption of a closed urinary drainage system and may prevent CAUTI. Limited evidence suggests that routine catheter changes every 4 to 6 weeks reduce CAUTI incidence in patients managed by long-term catheterization. Existed evidence suggests that the following interventions are not effective for reducing CAUTI incidence: (1) use of sterile technique for catheter insertion, (2) use of antiseptic solutions or ointments during routine meatal care, (3) use of a 2-chambered urinary drainage bag, (4) use of antiseptic filters incorporated into a urinary drainage bag, (5) bladder or catheter irrigation, (6) frequent changes of the urinary drainage bag, and (7) placement of an antiseptic solution in the urinary drainage bag. IMPLICATIONS FOR PRACTICE: Evidence from parts 1 and 2 of this Evidence-Based Report Card provides a sound basis for designing an evidence-based program to prevent CAUTI. Essential elements of a CAUTI prevention program include staff education, ongoing monitoring of CAUTI incidence, monitoring catheter insertion and ensuring prompt removal, and careful attention to techniques for catheterization and catheter care.

The AAWC conceptual framework of quality systems for wound care.

When the Association for Advanced Wound Care Quality of Care Task Force members determined there was no unanimously accepted definition of quality as it relates to wound care, they: 1) identified relevant components of quality wound care, and 2) created a framework of quality wound care indicators to enable the creation or assessment of wound care delivery systems. The framework is an innovative conceptual model that serves as a basis for the Association strategies to facilitate high quality wound care for patients/clients across the continuum of care and recognizes the role of the supporting systems necessary to provide wound care services. It uses the Institute of Medicine's Crossing the Quality Chasm: A New Health System for the 21st Century to define quality systems for wound care and includes safety and effectiveness coupled with the delivery of timely, efficient, equitable, collaborative, patient-centered care. This framework can be utilized during clinical, managerial, or regulatory review of wound care service delivery.
