Case Studies in Process Improvement

Factors Affecting Cardiac Troponin Error Rate

Expires July 2016


Christopher Koch was part of a 10-person team that investigated factors contributing to erroneous cardiac troponin results observed in the Hospital Clinical Laboratory. The team used a Define, Measure, Analyze, Improve, and Control approach and Six Sigma Methodology to identify methods to reduce erroneous troponin results. This presentation explains the steps they went through to achieve this improvement in the quality of troponin testing in the laboratory as well as reduction in supply and FTE costs.
