What is the Plan-Do-Study-Act (PDSA) cycle used for in quality improvement?

• A. Plan, Do, Check, Adjust as a standard quality improvement cycle.
• B. Collect data, analyze trends, and publish results.
• C. Plan, Do, Study, Act to plan a change, implement it, study the results, and act on findings to refine or spread the change.
• D. Define goals, assign tasks, and monitor budgets.

Answer: (C)

The Plan-Do-Study-Act cycle is an iterative method for quality improvement that guides how to test and refine changes in real-world settings. You Plan a change you want to test, then Do it on a small scale to see how it works in practice. Next, you Study the results to understand what happened, whether the change produced the desired improvement, and what was learned from the process. Finally, you Act on those findings by refining the change or deciding to spread it more broadly if it proves beneficial. This approach is about learning quickly from small tests, then adjusting before wider implementation. The other descriptions don’t capture this learning loop: one focuses on a different terminology for monitoring results, another emphasizes data collection and publication rather than testing and refining, and another describes general project management steps rather than an iterative improvement cycle.
