  1. Six Sigma Tools for Radiation Medicine Six-Sigma Tools for a “No-Fly” patient Safety Oriented, Quality-Checklist Driven, Paperless Multi-Center Radiation Medicine Department Ajay Kapur, PhD; Louis Potters, MD; Linda Mallalieu M.Sc Radiation Medicine North Shore-LIJ Health System New Hyde Park, NY

  2. Introduction • Tendencies to rush treatments, and environments of care with high operational variability →risk expedited care. • In the current environment of care in Radiation Medicine, several incidents have occurred that substantiate such risks. • In this work we focus on 6s methods to rationally counteract these tendencies towards a culture of patient safety

  3. Radiation Medicine at North Shore-LIJ Paperless and Quality Checklist (QCL) Driven Operations since 2007 Evidenced Based Treatment Directives for Standardization of Care 2800 consults/yr; 2100 Tx with EBRT 4 Locations, >100 staff; 165 patients/day 8 Linacs ; 37000 treatment fields per year (70% with IMRT) A Variance Rate under 0.01% per year. Custom Aspects-of-Care Event Reporting Database A Multi-disciplinary Quality Management Team 3

  4. Standardized Process – The Checklist • Multiple Handoffs Pivoted to Multiple Control Points • Treatment Start is the Point of Confluence of All Tasks 4

  5. Summary of Events Reported Errors Propagate QCL Task Delays Occur 5

  6. Questions Asked • How to Identify High Risk Steps in the Radiation Medicine Process? • How to Create a Proactive “Safety First” Culture? • How to Minimize Operational Variability? • What can we learn from 6-sigma best practices for safety?

  7. Application of 6s Methods to the Radiation Process 2007-2009 2009-2011

  8. QCL PROCESS MAP FAILURE MODES AND EFFECTS ANALYSIS Define Most Physics Tasks, Contours, Path review High Risk Tasks RISK Recast Checklist into a Risk Pareto Chart to Identify High Risk Steps 8

  9. Measure Benchmarking Performance [2009] PERFORMANCE INDICATORS • Slip Days (m) • Standard Deviations (s) • Z-Scores of QCL processes ‘DEFECTS’ OR DELAYS T

  10. Analyze Analysis of High Risk Tasks (2009) SLIP DAYS

  11. Improve Risk Mitigation and Workflow Improvement ISMP EFFECTIVENESS • Data Driven QCL Process Remapping / Streamlining • Revised Workflow and Task Due Dates • Dedicated Task Coordination and Scheduling • Process Interlocks – No Fly Policy • Tx starts only after ALL QCLs are complete per defined timeline • No last minute starts are allowed • Cultural shift from ‘just in time’ to ‘cancel if not ready’

  12. RESULTS – HISTOGRAMS OF SLIP DAYS

  13. RESULTS: WORKFLOW IMPROVEMENTS AND STABILIZATION 2009-2011 • PROJECT PHASES • Baseline 2009 • Transitional 2010 Jan – June • No-Fly July 2010 - current • Significant Reduction in Mean Delays as well as Operational Standard Deviation ( > 3X) 14

  14. RESULTS: WORKFLOW IMPROVEMENTS AND STABILIZATION 2009-2011 Control BASELINE 2009 TRANSITION NO-FLY 15 • Workflow improvements from Baseline to No-Fly Phases

  15. Control RESULTS: HIGH RISK QCL Z-SCORE IMPROVEMENTS 2009-2011 BASELINE TRANSITION NO-FLY Target: 2.00+ 0.25 May 2011 : 1.76 16

  16. Results: Transition to Proactive “Safety First” Culture • Reduction in Computed Number of No Fly Events • Most delays are currently proactive • - Contouring delays, Plan Modifications, Scheduling Errors • Reporting Efficiency Has Increased

  17. Discussion Analysis of baseline metrics for high risk QCL tasks showed we were at risk, with large variability and last minute rushed completions despite no observed misadministrations. Pressures to “treat fast” in environments where upstream tasks are delayed may force rushed physics task completions –such conditions may breed errors. Our baseline scores may represent a spectrum of operational efficiencies for many departments. Implications for Patient Safety: Detailed QCLs and Operational Procedures may not be enough to mitigate risk Quantitative analysis led to Workflow Improvement for Key Stress / Risk Steps (m,s >3X; Z score ~20%) Forced delays for incomplete High Risk QCL tasks support a “Safety First” culture 6s tools led to workflow and safety culture improvements 18
