Penn Medicine Multi-Pronged Approach Reduces Bloodstream Infections
Central line-associated bloodstream infections (CLABSI) fell by more than 90 percent during the past three years at the Hospital of the University of Pennsylvania due to a multi-pronged approach combining leadership initiatives, electronic infection surveillance, checklists to guide line insertion and maintenance, and implementation of the Toyota Production System to encourage best practices in line care. The findings, which Penn physicians said provide a road map for cutting the deadly, costly toll of hospital-acquired infections nationwide, were presented on March 20 at the 19th Annual Meeting of the Society for Healthcare Epidemiology of America (SHEA).
“We were only able to see a sustained reduction in infections when we took a multifaceted approach throughout the entire hospital. There are many procedures, many steps and many personnel that are involved in the placement, care and maintenance of central venous catheters. We have learned that a successful program to reduce CLABSI must take all of these factors into consideration,” said Neil Fishman, MD, director of Healthcare Epidemiology and Infection Prevention and Control at the 735 bed Philadelphia hospital and president-elect of SHEA. “Central line-associated bloodstream infections can add up to $40,000 to the cost of a hospitalization and take their toll in human lives. The mortality rate of CLABSI has been reported as high as 30 percent. Our program ultimately makes the hospital a safer place to receive medical care.”
Previous studies on CLABSI reduction efforts have focused only on intensive care units, but since the majority of CLABSI cases occur on other hospital floors that care for acutely ill, high-risk patients who require the long-term venous access for delivery of IV medications or nutrition, the Penn investigators sought to identify ways to eliminate all preventable infections of this kind.
When the campaign began in the fall of 2005, more than 30 patients with central lines developed bloodstream infections in the hospital each month. Over time, however, a series of process, technology, and equipment improvements has cut the number of infections to less than five each month. Only one case was reported in February of 2009.
Key early components of the effort called for strict adherence to hand hygiene; chlorhexidine to clean the skin prior to procedures; and sterile techniques during line insertion, access, and dressing changes. Checklists helped prompt staff adherence to the guidelines. New technology to improve management of catheter insertion sites also played an important role in battling the infections. When the authors identified problems with the handling of the line dressings--they were poorly placed or falling off, leaving room for bacteria to enter the line--they introduced a more adherent bandage and began using a new chlorhexidine (CHG) sponge. The sponge contains an antiseptic that can kill bacteria before they gain access to the bloodstream.
When the staff learned that a special cap that had been used to keep blood from clotting inside the lines was associated with increased bloodstream infections, its use was eliminated, leading to another drop in CLABSI rates.
