1 Lean Six Sigma in Healthcare Improving Healthcare at Presbyterian Healthcare Services Using Lean Six Sigma

2 Learning Objectives Why we need to improve our processes What is Lean Six Sigma Why do we need to have Lean Six Sigma Presbyterian Process for Improvement Case Studies

3 What you will gain Introduction to Lean Six Sigma What it takes to implement successful Lean Six Sigma How to sustain the gains from the improvement

4 THE BURNING PLATFORM

5 Costs and Spending Health Care Cost in the United States $2.3 Trillion $253 Billion $714 Billion Health Care Spending KaiserEDU.org : Health Policy Explained US Health Care Cost

6 What s driving Healthcare Reform? Technology & Prescription Drugs Chronic Disease Aging of the Population Administrative Cost

7 What are the Major Proposals to Contain Cost? Investment in information technology Improving Quality and Efficiency Adjusting Provider Compensation Government Regulation Prevention Increasing Consumer Involvement in purchasing Altering the Tax Preference for Employersponsored insurance

8 What do we all see as Customers of Healthcare? Clinical Issues Long waits in ED Wrong Surgeries Prescribing wrong medicine and dosage Financial Issues Incorrect Billing of charges Timely filing issues; denials from payers Inaccurate charges for procedures Poorly developed and inefficient processes Multiple handoffs and rework adding increasing cost

9 What s really driving cost in Healthcare Inefficient processes Lack of communication Processes developed over time Band-Aid approach to fixing problems Complex processes built around silos

10 WHAT IS LEAN SIX SIGMA

11 DMAIC Methodology Define Control Improvement Measure Improve Analyze Used to reduce defects or improve a current process

12 LEAN Methodology Define Value Control Process Improvement Measure Value Improve Process-Flow Analyze Process-Flow Used to reduce waste or shorten cycle times

13 DMADV Methodology Goal: Developing a process that provides the Customer the products and services that best meets their expectations. h b h i Verify Define Design Measure Design Analyze Used to create a new process

14 Lean Six Sigma Methodology LEAN DMAIC Define Control Process Improve Process- Flow Define Vl Value Lean Improvement Analyze Process- Flow Measure Value DMADV Define Control Improvement Measure Verify Design Measure Improve Analyze Design Analyze

15 Define: Scoping the Project Finding the Scope Charter SIPOC Process Mapping Capturing the Voice of the Customer (VOC) External view of our process and issues Talk to our customers to understand their pain points

16 Define: Right Players on the Project Oversight Boards and Committees Leadership Champions Ownership Process Owners Work Team Members Facilitators Black Belts

17 Define: Capturing the Voice of the Customer Who is the Customer? What drives the Customers to have difficulties with our products/processes? Where are the pain points in the process? How inefficiencies causes customer complaints? lit? Translation of Key Issues to Critical to Quality Understanding of what we should be measuring

18 Measure: Understanding Baseline Data Using Data to make Decisions Stop using gut feel and anecdotes to make decisions Review the numbers to help truly identify problem areas Understand baseline to determine if changes make a difference Capture current performance levels

19 Measure: Understanding the Basic Formula Y = f(x) Process Input x 4 Step 1 In-Proce ess x 1 In-Proce ess x 2 In-Proce ess x 3 Input x 5 Step 2 Step 3 Step 4 Output Y Input x 6 Input x 7 Input x 8 Input x 9 Y = f(x 1 ) + f(x 2 ) + f(x 3 ) + + f(x n )

20 Measure: Using Root Cause Analysis Tools Use basic tools that have been around since for over 100 years Process Mapping pp g Cause and Effect Diagram Pareto Analysis y FMEA

21 Other Tools in the Toolbox Lean Toolbox Ohno Circle 8 Waste Reduction 6S Group Huddle Value Stream Map (VSM) Product Process Flow (PPF) Full Work Analysis (FWA) Group Technology Mistake Proofing Changeover Capacity and Labor Review Line Balancing Standard Work Kanban & Point of Use Video Analysis Visual Controls Six Sigma Toolbox Charter SIPOC Process Map Pareto Analysis Cause and Effect (Ishikawa hk Diagram) FMEA Histogram Barrier Analysis Brainstorm/Affinitize Measurement System Analysis (MSA) Box Plots Basic Statistical Graphs Process Capability Hypothesis Testing Design of Experiments (DOE) Pugh Selection Matrix + Others Quality Function Deployment

22 Analyze: What Xs will make a difference to the Y Understand the affects of each root cause (X) on the output (Y) Use basic data analysis tools Use statistics to test hypothesis Drive decision making using analysis tools Eliminate the Xs that don t make a difference

23 Analyze: Understanding the Cause for Poor Performance f(x2) f(x4) f(x6) f(x8) f(x3) Y = f(x1) f(x7) f(x5 ) f( (x9) Y = f(x 1 ) + f(x 5 ) + f(x 7 ) + f(x 9 )

24 Analyze: Identifying the Critical Xs Understand the current problems Define What s the problem? What s the customer telling us? What s Critical for Quality? Identify Potential (Xs) in all areas that may affect the Outcome (Y) Measure Where s the breakdown? Why s the process failing? How well are we doing? Validated Xs that attribute for the majority of the problems. What are the few areas that drive the poor performance. Analyze Which Xs presents the biggest issues? Which Xs really causing a problem?

25 Improve: Develop Solutions to Eliminate Failures for Xs Innovate through out of the box thinking Shift your paradigm Status quo changes must be stopped Work with stakeholders to help develop ideas for improvement

26 Improve: Working with Teams Help spread process understanding Improve understanding of each other s work Promote team approach to problem solving Break down silos across the system Use the team s collective understanding di

27 Change Management Help with change Provide the need for change Constant communication from Sr. Leadership and through Project Team Provide upfront changes to help eliminate problems Work with key staff in each area to promote test of change

28 Improve: Developing Solutions Use the Front Line Staff to identify solutions Conduct pilot testing to test effectiveness ect ess of change Develop improvements throughout testing process Implement multiple solutions to fix single problem

29 Control: Sustaining the Gains Monitor and Show Performance Elicit improvements from all staff members Develop control plans to help determine actions Setup the front line staff to self monitor

30 Change Management Communicate throughout the system from start to finish Change the culture through changing how we manage System thinking identify process that best suits the organization Work as a team to eliminate system problems Break down barriers Resource and support

31 Why the Methodology Works Organization Level Systematic and structured approach to problem solving and improvement Oversight at various levelsl Senior management supported Operational Level Meeting deliverables for tollgates Operation owned improvements Official handoff and transition improvements into Operations 1 Internal and External Customers

32 Presbyterian s Quality Infrastructure for Sustained Improvements HOW DO WE IMPROVE?

33 What is Quality At Presbyterian Quality Means Having Excellent Services Free of Deficiencies What customers and stakeholders tkh want How they expect it delivered dli d

34 The Value of Quality Quality of a System Impacts the Bottom Line Excellent Services Customers Expect Free from Deficiencies Market Leader Fair Price Faster Cycle Times Lower Costs Less Rework Higher Vl Volume Improved Margins Lower Total Cost

35 Quality at Presbyterian Our quality initiatives allow us to deliver: Improved patient safety Improved patient satisfaction Improved patient access Improved outcomes Improved financial returns Decreased length of stay Lowered supply costs

36 Process Excellence Through different types of projects Process Excellence helps drive quality improvements at Presbyterian Different Tools for Different Goals Lean Six Sigma (DMAIC) Design for Six Sigma (DMADV) Successful projects require involved leaders and engaged front-line staff
