Handwashing practice and policy variability when caring for central venous catheters in paediatric intensive care.

It has been estimated that there may be as many as 150,000 healthcare associated infections (HCAI) in Australia each year, contributing to 7,000 deaths, many of which could be prevented through the implementation of appropriate infection control practices. Contact with contaminated hands is a primary source of HCAI. Intensive care staff have been identified as one of the least adherent groups of health care professionals with handwashing; they are less likely to practise hand antisepsis before invasive procedures than staff working in other patient care specialties. The study examined the self-reported clean and aseptic handwashing practices of nurses working in paediatric intensive care units (PICUs) across Australia and New Zealand, the patterns in variation between nurses' reported handwashing practices and the local policies, and patterns in the duration of procedural handwashing for specific procedures. A survey was undertaken in 2001 in which participating tertiary paediatric hospitals provided copies of their infection control policies pertaining to central venous catheter (CVC) management; five nurses on each unit were asked to provide information in relation to their handwashing practices. Seven hospitals agreed to participate and 30 nurses completed the survey. The study found an enormous level of variation among and between nurses' reported practices and local policies. This variation extended across all aspects of handwashing practices - duration and extent of handwash, type of solution and drying method used. The rigour of handwashing varied according to the procedure undertaken, with some evidence that nurses made their own risk assessments based on the proximity of the procedure to the patient. In conclusion, this study's findings substantiate the need for standardisation of practice in line with the current Centers for Disease Control and Prevention Guidelines, including the introduction of alcohol handrub.

A comparison of peripheral and centrally collected cyclosporine a blood levels in pediatric patients undergoing stem cell transplant.

PURPOSE/OBJECTIVES: To measure differences in cyclosporine A (CSA) trough concentrations from blood collected as a peripheral sample and from a CSA-uncontaminated (naive) lumen of a double-lumen central line. DESIGN: Prospective, comparative study. SETTING: Pediatric university teaching hospital in metropolitan Australia. SAMPLE: 71 paired central and peripheral CSA blood samples from a convenience sample of 14 pediatric allogeneic stem cell transplant recipients receiving IV CSA as prophylaxis or treatment for graft-versus-host disease. Ages ranged from 2 months to 14 years, 5 months. METHODS: Comparing blood samples collected from a peripheral site and a CSA-naive lumen of a double-lumen central line. Data were analyzed using a paired student t test and calculation of the 95% confidence interval of the concentration ratio from different sampling sites. MAIN RESEARCH VARIABLES: Site of blood sampling and CSA trough concentrations. FINDINGS: No significant difference existed between CSA concentration in samples collected from the different sites in children receiving intermittent infusions of CSA (p = 0.13). The 95% confidence interval of the CSA concentration ratio was 0.92 1.04. CONCLUSIONS: When CSA is administered on an intermittent dosing schedule, comparable CSA trough concentrations can be determined from blood collected via the CSA-naive lumen of a double-lumen central line or at a peripheral sampling site. IMPLICATIONS FOR NURSING: Pediatric allogeneic stem cell transplant recipients who require regular CSA trough concentrations no longer will require peripheral blood samples when receiving an intermittent dosing schedule.

Central venous access and handwashing: variability in policies and practices.

This study examined variability in handwashing policy between hospitals, variability in handwashing practices in nurses and how practice differed from policy in tertiary paediatric hospitals in Australia and New Zealand. Eight of the possible nine major paediatric hospitals provided a copy of their handwashing and/or central venous access device (CVAD) policies, and 67 nurses completed a survey on their handwashing practices associated with CVAD management. A high degree of variability was found in relation to all the questions posed in the study. There was little consistency between policies and little agreement between policies and clinical practice, with many nurses washing for longer than required by policy. Rigour of handwashing also varied according to the procedure undertaken and the type of CVAD with activities undertaken farther from the insertion site of the device more likely to be performed using a clean rather than an aseptic handwashing technique. As both patients and nursing staff move within and between hospitals, a uniform and evidence-based approach to handwashing is highly desirable.
