First released in August 2016, and updated regularly, CLEAR maintains a comprehensive annotated bibliography of empirical studies and systematic reviews of lean in healthcare for researchers and those seeking a detailed overview of the literature.

Articles are organized by whether they addressed 1) health, process, satisfaction, and cost outcomes; 2) components, methods, barriers, and facilitators of lean healthcare interventions; or 3) lean tool development, testing, and validation in healthcare. For primary articles, papers are further sub-categorized by the organizational unit (e.g. ER, surgery, laboratory) in which lean was implemented.
