What is Plan-Do-Study-Act in interprofessional quality improvement?

• A. Four-step iterative method to test changes
• B. Single-phase implementation
• C. Only used for budgeting
• D. Not used in healthcare

Answer: (A)

Plan-Do-Study-Act is a four-step, iterative method used in quality improvement to test changes and learn from the results before making broader implementations. In healthcare teams that bring together different professionals, this approach helps test small improvements in real practice rather than attempting one large change all at once.

Plan: identify the problem or opportunity, decide what change to try, and predict what will happen, including how you’ll measure it.

Do: implement the change on a small scale or a limited setting to test its effect.

Study: collect and analyze data to see if the change produced the predicted outcomes and to learn what actually happened.

Act: decide whether to adopt the change, adapt it, or abandon it, and then plan the next cycle based on what was learned.

Because PDSA cycles are repeated, teams can refine processes gradually, learning from each test before expanding, which is why it’s a fundamental tool in interprofessional quality improvement. It’s not a one-shot rollout, not specific to budgeting, and it’s clearly used in healthcare settings.
