Applying multi‐rules at the workstation ACTIVITY: The Front‐line Worker 1 Activity: The Front‐line Workers Purpose What will you do? To assess whether or not an analytical run is acceptable using the Westgard Working in groups of 4, you will: Multirule algorithms provided. Keep the QC scenario worksheets What will you need? face‐down until instructed to turn • Handout: Westgard Rules them right‐side up. Use the 6 minutes provided to: • Worksheet 1: Scenario 1 • Worksheet 2: Scenario 2 Review the QC chart, • Worksheet 3: Scenario 3 determining which analytical • Pencils runs are acceptable or Scoring unacceptable. + 5 for being the first group completed Arrive at a group consensus + 5 for only circling all the correct, out‐ of control answer(s) Circle the analytical run 7 for circling an acceptable run numbers that are unacceptable ‐ and/or for not circling an unacceptable run (Why?
