- Central line associated bloodstream infections (CLABSI) are responsible for significant patient morbidity, mortality and increased length of stay resulting in higher healthcare costs.
- Organisms from the hospital environment, healthcare worker hand and patient’s own flora contribute to colonization of needleless connectors. Once colonized, there is an increased risk of CLABSI.
- Previous studies demonstrated a low compliance with disinfection practices of needleless connectors1.
- Manual disinfection is insufficient to disinfect heavily contaminated connectors and thus prevent CLABSI.
- Use of a disinfectant cap increases compliance and improves the quality of disinfection and contributes to CLABSI reduction.
- Monitor nurses’ compliance with a disinfectant cap in a 440 bed tertiary care Trauma 1 center.
- Determine the effect of implementation of a disinfectant cap on the rate of CLABSI and contaminated blood cultures.
- Collaborate with front line staff on implementation strategies to prevent CLABSI.
- In January 2012, a disinfectant cap was implemented for all central and peripheral needleless connectors in all inpatient departments in a large tertiary care center (excluding women’s services).
- Rates of CLABSI and blood culture contamination were compared before and after implementation.
- Cost savings estimated using $25,000 for CLABSI and $2,500 for blood culture contamination2.
- Weekly audits performed by nursing students, staff and PIs.
- Required on-line modules or vendor in-service on use of the disinfectant cap.
- Required on-line module on proper blood culture drawing technique.
- Weekly compliance of the disinfectant cap reported to the nurse managers.
- Just-in-time education given to staff during the audit process, including proper care of the secondary tubing set.
- Solicited feedback from staff. Nurses identified need for fewer needleless connectors resulting in the purchase of no-port tubing. These changes resulted in cost savings and increased staff satisfaction.
Significant decrease in rate of CLABSI (t (22) = 2.73, p=.01):
2011 (M=1.4, SD=.37)
2012 (M=.88, SD=.61)
Significant decrease in rate of contaminated blood cultures (t (22) = 7.7, p<.01):
2011 (M=2.6; SD=.39)
2012 (M=1.5; SD=.29)
CLABSI estimated cost = $25,000/incidence; contaminated blood culture estimated = $2,500/incidence)
- The use of a disinfectant cap was effective in reducing the rate of CLABSI and contaminated blood cultures in a tertiary care center and providing substantial cost savings.
- Use of a disinfectant cap had a greater impact on reducing gram positive organisms.
- Nursing feedback was essential and provided unexpected savings (no-port tubing).
