This article will demonstrate how to conduct a quality improvement project using the change idea generated in "How To Use Quality Improvement Tools in Clinical Practice: How To Diagnose Solutions to a Quality of Care Problem" by Dr. Ziv Harel and colleagues in this Moving Points feature. This change idea involves the introduction of a nurse educator into a CKD clinic with a goal of increasing rates of patients performing dialysis independently at home (home hemodialysis or peritoneal dialysis). Using this example, we will illustrate a Plan-Do-Study-Act (PDSA) cycle in action and highlight the principles of rapid cycle change methodology. We will then discuss the selection of outcome, process, and balancing measures, and the practicalities of collecting these data in the clinic environment. We will also introduce the PDSA worksheet as a practical way to oversee the progress of a quality improvement project. Finally, we will demonstrate how run charts are used to visually illustrate improvement in real time, and how this information can be used to validate achievement, respond appropriately to challenges the project may encounter, and prove the significance of results. This article aims to provide readers with a clear and practical framework upon which to trial their own ideas for quality improvement in the clinical setting.Clin J Am Soc Nephrol 11: 908-914, 2016. doi: 10.2215/CJN.11511015
Clinical ScenarioIn the previous article in this Moving Points feature (1), the improvement team performed a root cause analysis to examine, by way of example, reasons why more patients were not dialyzing independently at home. The change idea that this analysis generated was the addition of a nurse educator into the CKD clinic. This change addressed the main causes of limited patient education by the nephrology staff and limited interdisciplinary communication between nephrology staff. Now, the improvement team needs to put this idea into practice and determine if the change is having the impact that was anticipated. Although the improvement team is familiar with Plan-DoStudy-Act (PDSA) methodology, they are unsure exactly how to conduct small tests of change and convey progress to the rest of the improvement team and stakeholders. In order to do so, the team needs to formulate a plan for how the nurse educator will be introduced into the clinic. The team must decide what parameters of success (or failure) are to be measured and identify a method whereby, in real time, they can tell if this change is having the desired effect and respond appropriately if it is not.
PDSA Cycles and Rapid Cycle Change MethodologyTo do this, The Model for Improvement suggests using a series of PDSA cycles in a process called rapid cycle change (2,3). This is an iterative process, whereby one cycle yields results that inform the next, and so on, toward reaching the eventual goal (Figure 1). Rapid cycle change can be thought of as being analogous to building a wall out of bricks rather than pouring a concrete floor. In the case of the wall,...
