内容説明
Step by step this comprehensive resource explores the statistical process control (SPC), a philosophy, a strategy, and a set of methods for ongoing improvement of processes and systems to yield better outcomes in health care organizations. It includes information on processes, stratification, rational subgrouping and stability and capability analysis, measurement, data collection methods, planned experimentation, and graphical methods. This book shows how to apply SPC to evaluate current process performance, search for ideas for improvement, tell if changes have resulted in evidence of improvement, and track implementation efforts to document sustainability of the improvement.
