What makes a ‘good’ PDSA
Alison BrownProject Manager, Clinical Governance Project

IHI Model for Improvement
• Three fundamental questions
• PDSA cycle provides a way of testing change ideas arising from the 3rd question
Project and PDSA Objectives
• 1st question is the project objective
• PDSA cycle test the strategy to be tried to reach objective(Plan includes objective of each PDSA test)
Objectives need to be SMART• Specific• Measurable• Achievable• Realistic• Timely
Objectives: Examples
We’ll do better on tests.
I will lose weight.
I’m going to exercise more often
Every member of our study group will increase his or her grade point average by 10 percent within eight months.
I will weigh 160 pounds by February 1.
I’m going to run 10 miles per week by July 4.
Objective: how good, by when, and for whom!
Measurement at 2 levels
• Project-level measures - answer the second fundamental question (evaluate the overall project objective )
• PDSA-level measures - data to evaluate the strategies tested in each of the linked PDSA cycle
• Measures may be different to measure project objective and PDSA tests
Step 1: Plan Plan the test or observation, including a plan for collecting data. State the objective of the test. State the questions you want to answer and make predictions about what will happen and why. Develop a plan to test the change. (Who? What? When? Where? What data ?)
Step 2: DoTry out the test on a small scale. Carry out the test. Document problems and unexpected observations.
Step 3: Study Set aside time to analyze the data and study the results.Complete the analysis of the data. Compare the data to your predictions.Summarize and reflect on what was learned.
Step 4: Act Refine the change, based on what was learned from the test. Determine what modifications should be made.Prepare a plan for the next PDSA
PDSA – test not a task
