McQuillan, R. F., Silver, S. A., Harel, Z., Weizman, A., Thomas, A., Bell, C., Chertow, G. M., Chan, C. T., & Nesrallah, G. (2016). How to Measure and Interpret Quality Improvement Data. Clinical Journal of the American Society of Nephrology, 11(5), 908-914.
McQuillan et al. provide a comprehensive guide on measuring and interpreting quality improvement (QI) data in healthcare settings, particularly in nephrology. The article emphasizes the importance of selecting appropriate measures, including outcome, process, and balancing measures, to effectively track improvement efforts. It introduces the Plan-Do-Study-Act (PDSA) cycle as a framework for implementing and evaluating changes. The authors highlight the use of run charts as a powerful tool for visualizing data over time and detecting improvements or challenges in real-time. They explain how to construct and interpret run charts, including the application of probability-based rules to identify significant changes. The paper also discusses the importance of operational definitions for measures and offers practical advice on data collection and analysis. By providing a clear and practical framework, this article aims to equip healthcare professionals with the necessary skills to conduct and evaluate quality improvement projects in clinical settings.
