Key Question What tools can help my HIV care program analyze information and make decisions? Key Question
A Picture is Worth a Thousand Words Tools for Understanding Processes
Understanding Processes • Processes are the object of our quality effort • Improving quality means improving processes Flowcharts
Types of Processes in Health Care Patient flow Information flow Material flow Clinical practice Flowcharts
Flowcharts to Understand Processes A flowchart is a picture of the steps of a process to: • Understand the process • Identify potential sources of problems • Outline the ideal process steps • Enable communications with others Flowcharts
Creating a Flowchart • Agree on use and level of detail • Define starting and ending points • Document each step • Follow each branch to the end • Review the chart • Assign action items to fill in blanks and verify accuracy Flowcharts
Most Commonly Used Flowchart Symbols Activity Connecting lines Terminator Decision A Page connector Wait symbol Flowcharts
Is This an Efficient Process? Staff asks name, searches data- base for file Patient in system? Patient arrives at front desk Staff asks patient to be seated Yes No Patient waits Staff asks patient to provide information Nurse takes patient to exam room Flowcharts
Non-Real Work “The additional steps we do because everything in the process is not perfect.” Flowcharts
Tips for Success • Get the right people in the room • Drive out fear! • Use Post-it™ notes • Capture improvement ideas as you go • Record the major steps in one meeting • Carefully review the flowchart Flowcharts
Be Aware… Drawing intricately detailed flowcharts can exhaust the quality improvement team’s time, energy and resources! Flowcharts
A) True B) False Creating a good flowchart is the most important thing a quality improvement team can do. This is where a quality improvement team should start its work, and it should continue to work on the flowchart until it is accurate, complete, comprehensive and detailed. Test Question Flowcharts
A) It is important to use information that is based on fact and not anecdote. B) It is best to involve those who are part of the process. C) You can either use flowcharts to identify potential problem steps or outline the ideal process flow. D) The beginning and end points in a flowchart are not critical. Which of the following statements is NOT correct? Test Question Flowcharts
Analyzing and Displaying Data • Run charts • Histograms • Pareto diagrams Analyzing & Displaying Data
Run Chart Analyzing & Displaying Data
Creating a Run Chart • Horizontal axis = time • Vertical axis = performance • Plot and connect data points • If useful, add average, median, performance goal or improvement activities Analyzing & Displaying Data
What Are We Looking For? • Variation • Trends • Performance against a goal Analyzing & Displaying Data
Histograms Show Us… …the pattern of the distribution in a set of data: Number of days for follow-up GYN appointment Source: Institute for Healthcare Improvement Analyzing & Displaying Data
Constructing a Histogram • Horizontal axis = continuous variable (often time, also size, weight, age) • Vertical axis = frequency • Count how many fall into each category • Analyze and develop explanations for the pattern Analyzing & Displaying Data
Which Patterns Matter? Analyzing & Displaying Data
What the Patterns Tell Us • Bell-shaped: normal • Double-peaked: two of something • Skewed: why the long tail? • Truncated: why the abrupt end? • Plateau: ill-defined process Analyzing & Displaying Data
What’s our Pattern Here? Number of days for follow-up GYN appointment Source: Institute for Healthcare Improvement Analyzing & Displaying Data
The Pareto Principle • “Whenever a number of individual factors contribute to some overall effect, relatively few of those items account for the bulk of the effect” • Identifying these “vital few” helps make our improvement work effective and efficient Analyzing Data
Constructing a Pareto Diagram • Gather data on the contributing factors • Create histogram with the various factors, from largest to smallest • Calculate the cumulative percentages • Construct another vertical percentage graph • Connect a line starting from the top of the tallest bar Analyzing & Displaying Data
A) Run chart B) Histogram C) Both will work My QI team wants to see how often we meet our performance goal. Which data display tool should we use? Test Question Analyzing & Displaying Data
Organizing “Theories of Cause” Process problems are caused by: • Methods • Materials • Equipment • Environment • People Cause-and-Effect Diagrams
The Cause-and-Effect Diagram Organizes and displays theories about causal factors • Allows constructive use of anecdotes • Encourages a balanced view • Demonstrates complexity of the problem Cause-and-Effect Diagrams
Possible Causes of Delayed Test Results Source: Institute for Healthcare Improvement Cause-and-Effect Diagrams
Constructing a Cause-and-Effect Diagram • Write down the effect • Decide on major areas • Brainstorm possible causes • Ask “why?” 3 to 5 times • When ideas run low, ask for “just one more” • Check for logic, completeness and balance Cause-and-Effect Diagrams
Be Aware… Broad problem statements can lead to vague or unnecessarily complex cause-and-effect diagrams. Cause-and-Effect Diagrams
Have the Diagram, Now What? Need to test the theories On to your quality improvement work! Cause-and-Effect Diagrams
A) GYN follow-up appointments take a long time B) 65% of GYN follow-up appointments take two weeks or more C) Many GYN follow-up appointments happen within two days, why don't they all? D) GYN appointments don't take place on the weekends Choose the best "effect" statement: Test Question Test Question
Key Points • Flowcharts help you understand processes • Run charts, histograms and Pareto diagrams help you understand the variation in your data • Cause-and-effect diagrams help you gather and display theories about causes of problems Key Points
