Prevention of central venous line associated bloodstream infections in adult intensive care units

Despite the potential benefits central venous lines can have for patients, there is a high risk of bloodstream infection associated with these catheters | Intensive and Critical Care Nursing

Aim: Identify and critique the best available evidence regarding interventions to prevent central venous line associated bloodstream infections in adult intensive care unit patients other than anti-microbial catheters.

Methods: A systematic review of studies published from January 2007 to February 2016 was undertaken. A systematic search of seven databases was carried out: MEDLINE; CINAHL Plus; EMBASE; PubMed; Cochrane Library; Scopus and Google Scholar. Studies were critically appraised by three independent reviewers prior to inclusion.

Results: Nineteen studies were included. A range of interventions were found to be used for the prevention or reduction of central venous line associated bloodstream infections. These interventions included dressings, closed infusion systems, aseptic skin preparation, central venous line bundles, quality improvement initiatives, education, an extra staff in the Intensive Care Unit and the participation in the ‘On the CUSP: Stop Blood Stream Infections’ national programme.

Conclusions: Central venous line associated bloodstream infections can be reduced by a range of interventions including closed infusion systems, aseptic technique during insertion and management of the central venous line, early removal of central venous lines and appropriate site selection.

Removal of sinks and introduction of ‘water-free’ patient care

Sinks in patient rooms are associated with hospital-acquired infections | Antimicrobial Resistance & Infection Control

Background: The aim of this study was to evaluate the effect of removal of sinks from the Intensive Care Unit (ICU) patient rooms and the introduction of ‘water-free’ patient care on gram-negative bacilli colonization rates.

Conclusions: Removal of sinks from patient rooms and introduction of a method of ‘water-free’ patient care is associated with a significant reduction of patient colonization with GNB, especially in patients with a longer ICU length of stay.

Monitoring the hand hygiene compliance of health care workers

Brotfein, E. et al. American Journal of Infection Control | Published online: 4 May 2017

Highlights:

  • CCTV is a new and reliable method for observation of hand hygiene.
  • CCTV methodology records a different performing hand hygiene compared to overt observation.
  • Covert observations using CCTV can replace direct overt observation for hand hygiene of HCWs.

The value of direct observation to reduce catheter-associated urinary tract infection

Afonso, E. & Blot, S. Intensive and Critical Care Nursing | Published online: 26 April 2017

Urinary tract catheterization and monitoring of the urinary output is indispensable in critically ill patients as might indicate intravascular circulating volume, organ perfusion, and pending shock (Paratz et al., 2014; Eastwood et al., 2015). The presence of a urinary catheter however involves the risk of infection.

We read with interest the article by Galiczewski and Shurpin (2017) about the efficiency of direct observation to reduce bladder catheter utilization and catheter-associated urinary tract infections in the ICU.

Improving the catheter associated UTI rate in an intensive care unit

Galiczewski, J.M. & Shurpin, K.M. Intensive and Critical Care Nursing. Published online: 22 February 2017

Background: Healthcare associated infections from indwelling urinary catheters lead to increased patient morbidity and mortality.

Aim: The purpose of this study was to determine if direct observation of the urinary catheter insertion procedure, as compared to the standard process, decreased catheter utilization and urinary tract infection rates.

Conclusion: The findings from this study may promote changes in clinical practice guidelines leading to a reduction in urinary catheter utilization and infection rates and improved patient outcomes.

Transmission of Staphylococcus aureus between health-care workers, the environment, and patients in an intensive care unit

Price, J.R. et al. (2017) The Lancet Infectious Diseases. 17(2) pp. 207–214

11708-2

Background: Health-care workers have been implicated in nosocomial outbreaks of Staphylococcus aureus, but the dearth of evidence from non-outbreak situations means that routine health-care worker screening and S aureus eradication are controversial. We aimed to determine how often S aureus is transmitted from health-care workers or the environment to patients in an intensive care unit (ICU) and a high-dependency unit (HDU) where standard infection control measures were in place.

Interpretation: In the presence of standard infection control measures, health-care workers were infrequently sources of transmission to patients. S aureus epidemiology in the ICU and HDU is characterised by continuous ingress of distinct subtypes rather than transmission of genetically related strains.

Hand Hygiene in Intensive Care Units: A Matter of Time?

Stahmeyer, J.T. The Journal of Hospital Infection. Published online: January 28, 2017

clock-650753_960_720

Background: Healthcare-associated infections are a frequent threat to patient safety and cause significant disease burden. The most important single preventive measure is hand hygiene (HH). Barriers to adherence with HH recommendations include structural aspects, knowledge gaps, and organizational issues, especially a lack of time in daily routine.

Conclusion: Complying with guidelines is time consuming. Sufficient time for HH should be considered in staff planning.
