BackgroundAs part of a strategic quality improvement plan, laboratory management at Sarasota Memorial Health Care System (SMHCS) focused its efforts on improving preanalytical work flow and blood collection processes-both negatively affected by hemolyzed specimens. When hemolysis is detected in a blood specimen, blood may need to be re-collected, resulting in bottlenecks and rework all along the value stream. From July through December 2009, hemolysis averaged 9.8% in the Emergency Care Center (ECC) and 3.4% housewide. The goal was set to reduce hemolysis to 2%.MethodsThe project team identified hemolysis as one of seven factors contributing to non-value-added activities and bottlenecks in blood collection and preanalytical processes. Observations and interviews helped to identify error-prone practices and process variation. To verify the root causes of hemolysis, the findings were compared against best practices. The team developed a housewide protocol, standardized collection processes, created competency-based training, and enhanced ECC hiring practices.ResultsDuring December 2010-March 2011, following initial housewide interventions and ECC self-sustaining solutions, ECC hemolysis decreased by 91%-from 9.8% (423 hemolyzed/4,295 collected) to 0.88% (58 hemolyzed/6,560 collected). Housewide hemolysis decreased by 59%-from 3.4% (2,046 hemolyzed/60,307 collected) to 1.39% (619 hemolyzed/44,528 collected). Since the project, hemolysis has continued to trend downward; the mean percentage has consistently been < .05% for the ECC and < 1% housewide.ConclusionLean-Six Sigma tools helped to pinpoint hemolysis as a key inefficiency in blood collection and preanalytical work flow. Although focused on the ECC, the project team standardized blood collection practices and instituted quality devices to achieve hemolysis reductions housewide.
