Removal of short-term indwelling urethral catheters.
This information on best practice discusses the evidence for the removal of short-term indwelling urethral catheters. The article has been reproduced with the permission of the Joanna Briggs Institute (JBI). The article is derived from a systematic review of research published by the JBI,'Comparison of late night and early morning removal of short-term urethral catheters: a systematic review' (...
متن کاملReducing the risk of infection with indwelling urethral catheters.
Reducing the risk of healthcare associated infection (HCAI) is a key government target (Department of Health, 2003). Indwelling urethral catheters are one of the most common invasive medical devices used in acute care settings and, consequently, are a frequent cause of HCAI. This article describes 10 key issues and best practice points for practitioners to consider when caring for someone who r...
متن کاملFrequency for Changing Long-Term Indwelling Urethral Catheters.
February 2016 Home Healthcare Now 105 denced-based guidelines. When the IUC is reinserted, microorganisms that inhabit the distal urethra can be directly introduced into the bladder and increase the risk for a UTI. Changing an IUC at routine, fixed intervals (e.g., 28 days or monthly) is not recommended by: • Association for Professionals in Infection Control and Epidemiology [APIC] (2014) • Ce...
متن کاملBiofilm formation of Klebsiella pneumoniae on urethral catheters requires either type 1 or type 3 fimbriae
Urinary catheters are standard medical devices utilized in both hospital and nursing home settings, but are associated with a high frequency of catheter-associated urinary tract infections (CAUTI). In particular, biofilm formation on the catheter surface by uropathogens such as Klebsiella pneumoniae causes severe problems. Here we demonstrate that type 1 and type 3 fimbriae expressed by K. pneu...
متن کاملBiofilms on indwelling urethral catheters produce quorum-sensing signal molecules in situ and in vitro.
Acylated homoserine lactones (AHLs) are chemical signals that mediate population density-dependent (quorum-sensing) gene expression in numerous gram-negative bacteria. In this study, gram-negative bacilli isolated from catheters were screened for AHL production by a cross-feeding assay utilizing an AHL-responsive Agrobacterium tumefaciens reporter strain. Positive reactions were obtained from 1...
