ORLANDO – A system-wide quality improvement process that utilized define, measure, analyze, improve, and control and rapid adoption methodology eliminated surgical site infections among patients undergoing isolated coronary artery bypass with donor site surgery at a regional medical center.
Between March 2012 and March 2013 the overall decline in the rate of surgical site infections among 250 patients surpassed the center’s goal of a 40% decrease in the infection rate to a rate of 1.61; instead, the center achieved a rate of 0.7 during that time period. Since May, 2012, no surgical site infections have occurred among coronary artery bypass graft patients, Candis Kles, a critical care nurse at Athens (Ga.) Regional Medical Center, reported at the annual meeting of the Society of Thoracic Surgeons.
"We are now into our 23rd month without a deep/organ space infection with over 454 patients," Ms. Kles said in a May interview.
The quality improvement process was initiated after the infection rates at the center were found to be high (ranging up to 6.1), compared with National Healthcare Safety Network data. Using the define, measure, analyze, improve, and control methodology, a multidisciplinary team was convened, including cardiothoracic surgeons, nurses, and support personnel, and a 6-month process was undertaken to identify areas for improvement, said Ms. Kles who chaired the team.
"We also at this time partnered with the VHA National Hospital Engagement Network for some extra training and to help us along the process," she noted.
The team flow-charted processes – from scheduled surgery to discharge – and posted the flow charts in the operating room and cardiac intensive care unit to identify inconsistencies and potential problem areas. Frontline staff members were engaged and encouraged to participate in the improvement process by posting notes, suggestions, and questions on the flow charts.
A literature review was conducted to ensure that current practices mirrored best practices.
Despite an extensive evaluation of possible patient-, procedure-, and hospital-related factors that might be associated with the infection rate, no single cause of the high rate was identified, although a number of areas for improvement were recognized. Among the changes that were implemented were use of chlorhexidine oral rinse, which was administered until discharge; use of disposable EKG leads (after high bacterial counts were found on the leads in use prior to program initiation); use of silver-impregnated midsternal dressings; a change in surgical and suture techniques; development of patient educational materials, and standardization of all processes, Ms. Kles said, noting that the changes were implemented rapidly.
The success of the program is largely attributable to input from all levels and disciplines within the organization – including physicians who championed the process, and to staff engagement and buy in, she said.
The improvement in the infection rate resulted in cost avoidance of $212,355 (compared with a total excess cost of surgical site infections of $250,965 in 2011), and in a reduction from 156 to 24 excess hospital days.
Ms. Kles reported that as of February 2014 she is a member of the speakers bureau for Mölnlycke Health Care, a maker of surgical and wound care products.
