Which steps comprise the PDSA cycle in quality improvement?

• A. Plan, Do, Check, Act
• B. Plan, Do, Study, Act
• C. Plan, Implement, Study, Act
• D. Plan, Do, Assess, Act

Answer: (B)

Understanding how improvement work progresses, the PDSA cycle consists of four steps: Plan, Do, Study, Act. Plan involves deciding what change you want to test, how you will implement it on a small scale, and which data you will collect to determine whether the change had the desired effect. Do is the actual testing of that plan in a real-world setting, but on a limited, manageable scope so you can observe what happens without risking widespread disruption. Study focuses on learning from the data gathered during the test. You analyze the results, compare them to your predictions, and ask what worked, what didn’t, and why. This step is about understanding the cause-and-effect relationship of the change, not just confirming that something happened. Act is where you decide what comes next. Based on what you learned, you may adopt the change more broadly, modify it and run another small test, or abandon it and start a new cycle with a different plan. The cycle is repeated to drive continuous improvement. For example, you might plan a small change to a reminder system to reduce missed appointments, implement it in one clinic for two weeks, study the impact on appointment show rates, and then decide to expand, adjust the reminder message, or stop the change depending on what the data show.
