Bloodstream infection rates in outpatient hemodialysis facilities participating in a collaborative prevention effort: a quality improvement report.

BACKGROUND: Bloodstream infections (BSIs) cause substantial morbidity in hemodialysis patients. In 2009, the US Centers for Disease Control and Prevention (CDC) sponsored a collaborative project to prevent BSIs in outpatient hemodialysis facilities. We sought to assess the impact of a set of interventions on BSI and access-related BSI rates in participating facilities using data reported to the CDC's National Healthcare Safety Network (NHSN). STUDY DESIGN: Quality improvement project. SETTING & PARTICIPANTS: Patients in 17 outpatient hemodialysis facilities that volunteered to participate. QUALITY IMPROVEMENT PLAN: Facilities reported monthly event and denominator data to NHSN, received guidance from the CDC, and implemented an evidence-based intervention package that included chlorhexidine use for catheter exit-site care, staff training and competency assessments focused on catheter care and aseptic technique, hand hygiene and vascular access care audits, and feedback of infection and adherence rates to staff. OUTCOMES: Crude and modeled BSI and access-related BSI rates. MEASUREMENTS: Up to 12 months of preintervention (January 2009 through December 2009) and 15 months of intervention period (January 2010 through March 2011) data from participating centers were analyzed. Segmented regression analysis was used to assess changes in BSI and access-related BSI rates during the preintervention and intervention periods. RESULTS: Most (65%) participating facilities were hospital based. Pooled mean BSI and access-related BSI rates were 1.09 and 0.73 events per 100 patient-months during the preintervention period and 0.89 and 0.42 events per 100 patient-months during the intervention period, respectively. Modeled rates decreased 32% (P = 0.01) for BSIs and 54% (P < 0.001) for access-related BSIs at the start of the intervention period. LIMITATIONS: Participating facilities were not representative of all outpatient hemodialysis centers nationally. There was no control arm to this quality improvement project. CONCLUSIONS: Facilities participating in a collaborative successfully decreased their BSI and access-related BSI rates. The decreased rates appeared to be maintained in the intervention period. These findings suggest that improved implementation of recommended practices can reduce BSIs in hemodialysis centers.

Essential components of an infection prevention program for outpatient hemodialysis centers.

Infections are a significant complication for dialysis patients. The CDC estimates that 37,000 central line-related bloodstream infections occurred in hemodialysis patients in 2008 and dialysis-associated outbreaks of hepatitis C continue to be reported. While established hospital-based infection prevention programs have existed since the 1970s, few dialysis facilities have an established in-center program, unless the dialysis facility is hospital-associated. This review focuses on essential core components required for an effective infection prevention program, extrapolating from acute-care programs and building on current dialysis guidelines and recommendations. An effective infection prevention program requires infrastructure, including leaders who place infection prevention as a top priority, active involvement from a multidisciplinary team, surveillance of outcomes and processes with feedback, staff and patient education, and consistent use of evidence-based practices. The program must be integrated into the existing Quality Assessment and Performance Improvement program. Best practice recommendations for the prevention of infection, specific to dialysis, continue to evolve as the epidemiology of dialysis-associated infections is further researched and new evidence is gathered. A review of case studies illustrates that with an effective program in place, infection prevention becomes part of the culture, reduces infection risk, and improves patient safety.

Sustained Infection Reduction in Outpatient Hemodialysis Centers Participating in a Collaborative Bloodstream Infection Prevention Effort.

Among dialysis facilities participating in a bloodstream infection (BSI) prevention collaborative, access-related BSI incidence rate improvements observed immediately following implementation of a bundle of BSI prevention interventions were sustained for up to 4 years. Overall, BSI incidence remained unchanged from baseline in the current analysis. Infect Control Hosp Epidemiol 2016;37:863-866.
