  1. QI Tool: The Fishbone Diagram EIS Quality Learning Network May 10, 2010

  2. Quality Improvement Tools What tools can help my HIV care program analyze information and make decisions?

  3. Organizing “Theories of Cause” Process problems are often caused by: Methods Materials Equipment Environment People

  4. Fishbone Diagram Organizes and displays all causes and sub-causes that may influence a problem, outcome, or effect Helps push people to think beyond the obvious causes, (money, time) to find some causes that they can fix/improve Helps organize potential solutions and make clear who should be involved in solutions Encourages a balanced view Demonstrates complexity of the problem

  5. Common Categories • People: Anyone involved with the process • Methods: How the process is performed and the specific requirements for doing it, such as systems,policies, procedures, rules and regulations • Measurements: Data generated from the process that are used to evaluate its quality • Equipment: computers, tools etc. required to accomplish the job • Materials: Raw materials, parts, pens, paper, etc. used to produce the final product • Environment: The conditions, such as location, time, temperature, and culture in which the process operates

  6. Creating a Fishbone Diagram Skeleton Equipment Environment Computer System down for routine maintenance Low show rate for appointments Patients Patient unaware of appointment Procedures People

  7. Example: Low Show-Rate for Medical Appts.

  8. Example: Delayed Test Results

  9. Fishbone Diagram: Practice(20 Minutes) • Write down the problem (fish head) • Decide on categories and draw skeleton (e.g., Environment, People, Equipment, Materials, Procedures, Policies, Measurements) • Brainstorm as many possible causes as you can and fill in the diagram • Ask “why does this happen?” 3 to 5 times • Check for logic, completeness and balance Practice Problem: Low return for confirmatory tests Please select a facilitator/recorder & report back to full group

  10. Have the Diagram, Now What? Need to test the theories On to your quality improvement work!
