The Health Foundation is a UK charity that was funded by an enormous endowment when the PPP Healthcare Group was sold. The charity supports work on patient safety and improvement science, along with other topics.
The charity publishes free monthly updates on patient safety and improvement approaches. There are many papers in their alerts that are relevant to Lean and other improvement approaches. It is possible to search their archive of relevant literature, and to subscribe to their monthly e-mail alerts. Most people working on Lean improvements are likely to find at least one or two articles a month that are of interest to them.
