Overview of Lean Principles and Continuous Improvement Lean in Healthcare
What is Lean? Definition-”The endless transformation of waste into value from the customer’s perspective.” Definition-”The endless transformation of waste into value from the customer’s perspective.” IT is a System Thinking Concept. A little History A little History
The “4P” model Problem Solving (Continuous Improvement And Learning) Process (Eliminate Waste) People and Partners (Respect, Challenge, and Grow Them) Philosophy (Long-Term Thinking)
Impact of Lean in the Industry Direct Labor/productivity improved 45-75% Cost Reduced 25-55% Throughput/Flow Increased 60-90% Quality (Defects/Scrap) Reduced 50-90% Inventory Reduced 60-90% Space Reduced 35-50% Lead Time Reduced 50-90% Source: Virginia Mason Medical Center
Examples of Lean in Healthcare Adding greater “value-added” services Adding greater “value-added” services Same day office visits Same day office visits Next day outpatient surgery Next day outpatient surgery Next day mammogram Next day mammogram Quick & errorless billing Quick & errorless billing No wait emergency room No wait emergency room
TRADITIONAL CULTURE VS. LEAN CULTURE TRADITIONALLEAN Functional Silos Interdisciplinary teams Managers direct Managers teach/enable Benchmark to justify not improving; “just as good” Seek the ultimate performance, the absence of waste Blame people Root cause analysis Rewards: individual Rewards: group sharing Supplier is enemy Supplier is ally Guard Information Share information Volume lowers cost Removing waste lowers cost Internal focus Customer focus Expert driven Process driven

What is Waste in Healthcare?
Eliminating Waste Overproduction Overproduction Pills given out early Treatments done to balance staff Duplication of test
Eliminating Waste Transportation Moving same patient, specimens, or supplies,workers
Eliminating Waste Motion Motion Searching for patients, needed meds, right charts, supplies
Eliminating Waste Waiting for bed assignments ordischarge,or testing results
Eliminating Waste Processing Retesting More paperwork Duplicate procedures
Eliminating Waste Inventory Inventory Linen (laundry) Pharmacy stock Supplies Specimens waiting for analysis
Eliminating Waste Defects Medication error Wrong procedure Wrong patient Missing information
The Toyota Way 14 Management Principles to LEAN Development Process to LEAN Development Process
LEAN Development Process 1. Establish the vision for the future Focus the organization on the PATIENTS Align Performance Measurements Set high expectations for success and low tolerance for failure Method: Establish a core team of implementers Focused training, reading, and benchmarking Standardized, systematic, methodical approach Clearly define objectives and time table Create success through pilots and spread
Mission Statement Develop the ability: To recognize and identify waste To have the courage to call it waste To have the desire to eliminate it Eliminate the waste Understand that waste simply Raises costs Produces no corresponding benefit Threatens all of our jobs You get what you expect and you deserve what you tolerate.
LEAN Development Process 2. Develop your objectives Look at your key processes or VALUE STREAMS Patient Journey (ER Radiology Clinic OR Billing) Charge capture (Clinical Service Billing Insurance) Operating Room flow (Scheduling, consent, pre-op visit, prep,….) These support your “ Products ” which might be Office visit Inpatient stay Visit to the ED How do your Internal and External Customers define Value
LEAN Development Process 3. Selection of Team Members Characteristics: Technology curiosity Common sense Inner confidence (create structure, Win allegiance, instinctive reactions) Cross Functional Team: Manager/Supervisor from the area Operators from area Functional departments (HR, Lab, Pharmacy, Admitting, Surgery, Materials Management,etc.)

LEAN Development Process 4. Initiate Team Training: Read required literature Attend team and leadership training, lean overview Tools: Standardized analysis and simulation tools Video cameras, TVs, and VCR’s Computers, Printer, and Projector Facilities: Lean War Room located in the operational area Office area appropriately furnished and supplied

LEAN Development Process 5. Select Pilot Area Selection Criteria: Contributes to key competitive strengths of business Innovation has a good chance of success Significantly tests the innovation Solutions are transferable to other areas Baseline the current process Do an initial walkthrough
Baseline Analysis 1. # patients transferred from ED to inpatient bed within 1 hour of decision to admit 2. Time to third next available appt 3. # tests/day or # tests/week Keep it simple - look at 25 patients/wk collected over some time period including weekends and at night
LEAN Development Process 6. Activity of Product Videotape: selected products Analyze videotape and segregate: travel time and distance storage time and type inspection time non-value added processing time value added processing time Map the flow of the product:
