Expanding on the concepts and tools of Lean hospitals and coupling these ideas with the principles of sigma six, this book presents a how-to guide to true efficiency in hospitals. Beginning with an overview and description of Lean tools, it demonstrates Lean implementation at every level of a hospital including the ED, OR, Radiology, and Cath Lab. The authors discuss traditional methods, typical problems, and a value stream map for each area and provide actionable blueprints, case studies, and lessons learned to facilitate the duplication of Lean improvements.
