Provides an overview of the evidence for using Lean in healthcare, summarises supporting tools and techniques, and outlines the challenges.

Lean is one of the most widely used improvement approaches in healthcare. With origins in manufacturing, it focuses on improving efficiency, eliminating waste, and streamlining processes. This Element provides an overview of the evidence for the use of Lean in healthcare, summarises the supporting tools and techniques, and emphasises the importance of developing an organisational culture committed to continuous improvement. The authors offer two case studies of attempts to implement Lean at scale, noting that, despite its popularity, implementation is not straightforward. Challenges include terminology that isn't always easy to grasp, perceived dissonances between the manufacturing origins of Lean based on repetitive, standardised, automated production and the human-centred world of healthcare, and problems with fidelity. The authors make the case that there is a lack of a robust evidence base for Lean and call for well-designed studies to advance the implementation of Lean and associated process improvement techniques in healthcare.
