The Systematic review of the application of the plan–do–study–act method to improve quality in healthcare was first published on the 11th of September 2013 by Michael J Taylor, Chris McNicholas, Chris Nicolay, Ara Darzi, Derek Bell, Julie E Reed.

Plan–do–study–act (PDSA) cycles provide a structure for iterative testing of changes to improve quality of systems. The method is widely accepted in healthcare improvement; however, there is little overarching evaluation of how the method is applied. This paper proposes a theoretical framework for assessing the quality of application of PDSA cycles and explores the consistency with which the method has been applied in peer-reviewed literature against this framework. – BMJ Quality and Safety Statistics.
