Which approach helps test a change that is implemented?
Correct Answer:
Plan-Do-Study-Act (PDSA)
Explanation:
In quality improvement, testing a change uses an iterative learning loop that lets you learn and adjust before broader rollout. Plan-Do-Study-Act provides this clear framework. Plan what change you will try and what you expect to happen. Do the change on a small, controlled scale. Study the results by collecting and analyzing data to see if the prediction held. Act based on what you learned—adopt, modify, or abandon the change—and then repeat the cycle as needed. This approach helps ensure the change actually leads to improvement without disrupting care on a large scale. The other options are more about broad planning or decision-making rather than a structured, repeated testing process, so they don’t fit as well for testing a change before full implementation.
