The document introduces the PDSA (Plan-Do-Study-Act) cycle as a framework for implementing a new safety program in a healthcare facility. PDSA was developed by Walter Shewhart as a model for continuous quality improvement. It involves planning an improvement, executing the plan, evaluating the results, and determining what actions to take going forward. Using PDSA supports better patient and system outcomes, professional development, and bridging the gap between planning and implementing improvements.
