Six sigma originated as a set of practices designed to improve manufacturing processes and eliminate defects. It applications, over time, have extended to radiation oncology. This article published in Practical Radiation Oncology1 looks at establishing the principles of six sigma to improve patient safety in a paperless environment at multiple radiation oncology sites.
The article describes the use of metrics in reducing patient safety risk. Methodologies used to redesign process, proactively eliminate errors, and correct system weaknesses include failure mode and effects analysis (FMEA), a no-fly policy, and root cause analysis (RCA).2
The article explains how a mapping of process is used to outline steps in the entire patient treatment flow. Rules and tasks were formulated to create procedural steps. Conformance to processes are measured and analyzed.3
The article concludes by stating principles of six sigma work in reducing patient safety risk. In addition, six sigma improves efficiency in work and quality processes.4
