purpose of lean implementation
Purpose of Lean Implementation
  • Initially, we needed a quality improvement method for our AHRQ RO1 “Improving Patient Safety by Examining Pathology Errors” 1992-1997
    • Measure current state of error in laboratory medicine (data: 30% of specimens are defective)
    • Perform root cause analysis and design error reduction initiatives (data: errors related to breakdown in various testing phases)
    • Implement error reduction and quality initiatives and measure effectiveness
purpose of lean implementation1
Purpose of Lean Implementation
  • Lab expenditure represents 5% of total healthcare expenditure
  • 70% of clinical decisions are based on lab information
  • Lab medicine testing failures have major downstream implications
    • Pre-pre-analytic phase – choice of the test
    • Pre-analytic phase – performance of the test
    • Analytic phase – processing and analysis of the specimen
    • Post-analytic phase – reporting of the test result
    • Post-post-analytic phase – use of the test result in patient care
scope of lean implementation
Scope of Lean Implementation
  • Institutions: University of Pittsburgh Medical Center, Henry Ford Health System, Western Pennsylvania Hospital, University of Iowa
  • UPMC Shadyside
    • Tertiary 486 bed urban hospital
    • Medical staff includes more than 600 primary care physicians and specialists
    • Provides cancer care to 30,000 patients annually (Hillman Cancer Center)
    • 2.11 million laboratory tests, 67 FTEs
    • Surgical pathology: ~ 20,000 specimens, 14 FTEs
scope of lean implementation1
Scope of Lean Implementation
  • Began implementation in August 2003
  • Chose to use Perfecting Patient Care™ (PPC) as the Lean improvement method
    • Education by the Pittsburgh Regional Healthcare Initiative
    • Jewish Healthcare Foundation funding for a team leader
    • Internal learning network
implementation methods
Implementation Methods
  • Implemented PPC in different ways
    • Use of a team leader
      • Histology section of anatomic pathology lab
    • Use of PPC principles
      • Cervical cancer prevention
        • Pap test procurement (pre-analytic)
        • Laboratory screening (analytic)
      • Invasive radiologic services
      • Breast cancer care
      • Specific lab phases (i.e., accessioning, gross examination, interpretation)
      • Reporting (post-analytic)
implementation methods1
Implementation Methods
  • Organizational commitment
  • Physician champions
  • Team leader
  • Internal collaboration
  • Front line workers
  • Design depended on input from those involved in the process
lean evaluation
Lean Evaluation
  • Metrics
    • Efficiency of services
      • Turn around time
      • Productivity
    • Quality
      • Error reduction
      • Resource utilization
      • Satisfaction
    • Costs
      • Business case analysis
results of interventional radiology implementation
Results of Interventional Radiology Implementation
  • Studied thyroid gland fine needle aspiration (FNA) services
  • Sensitivity: Pre-intervention: 70.2%; post intervention: 92.3% (P < 0.001)
  • False negative rate: Pre-intervention: 41.8%; post-intervention: 18.2% (P = 0.006)
  • Repeat FNA rate: Pre-intervention: 12.7%; post intervention (with immediate interpretation): 3.7% (P = 0.001)
  • Cost savings $167,000 per 100 patients ($501 million annually)
results of lab productivity1
Results of Lab Productivity
  • The number of UPMC Shadyside FTEs/day in 2003 and 2006 was 4.5 and 5.1, respectively and the productivity ratio was 3,439 and 4,074 work units/FTE, respectively (P < 0.001)
  • A second histology section produced 23,972 mean monthly work units with 15.0 FTEs/day and had a productivity ratio of 1,598 work units/FTE (P < 0.001)
  • Lack of organizational commitment
  • Turf issues
  • Training
  • Long term evaluation is problematic
  • Disruptive physicians
  • Middle management not engaged
  • Up-front costs
  • Cultural model (top down versus bottom up)
  • Punitive history difficult to eradicate
  • Disincentives for improvement
  • Difficulties in linking improvement with outcome
lessons learned
Lessons Learned
  • Metrics of quality, efficiency, and costs can be improved simultaneously
  • The more the front line is involved, the greater the improvement
  • An organizational leadership that is not engaged, fearful, and disruptive derails the process
  • Beware the drive for efficiency!
  • Workers need constant feedback and metrics with meaning
  • Difficulties with sustainability
  • True learning lines difficult to implement
knowledge transfer
Knowledge Transfer
  • Publications, work-shops, lectures
  • Shop floor walk through
  • On the job training
  • Disseminate principles to other labs
  • Development of a national lab medicine learning network
next steps
Next Steps
  • Experiment with implementing a true leaning line
  • Continue developing a national lab medicine Lean learning network
  • Develop models in different lab medicine settings
  • Learn how current disincentives may be reversed
  • Study how Lean may be implemented in different cultural models
