Selecting the correct control chart: A practical example from adolescent care

Abstract

Oftentimes physicians or clinic leaders are asked to embark on strategic or quality improvement initiatives to improve selected preventive and well child metrics. The first step in selecting the correct control chart for this work is understanding the type of data being measured. Once the type of data is determined, a standardized flowchart is used to select the correct control chart. Each type of data requires the correct control chart to display and monitor quality improvement efforts effectively. Understanding types of data and using a flowchart to select the appropriate control chart helps remove the mystery behind selection and ensures control charts can be used and interpreted correctly.
