Job Aid 1: Frequency of Chart Review 909 AWEsome Numbers Inc. OptimiZed Q.C. Processes - Sigma Patient-Focused Laboratory Quality Effective Date: 12/6/2016 HILS1746 OptimiZed Q.C. Process Sigma Sigma QC Rule Sample Front Line Supervisor Chart Investigation From To Strategy Frequency Chart Review Review and Quality 6.01 999.0 1-3.5s Routine 1-3.5s 1x / Week Improvement Action 1x / 4 Weeks None 5.51 6.00 Routine 1x / Week 1x / 4 Weeks None 5.01 5.50 1-3.0s Routine 1x / Week 1x / 4 Weeks None 4.50 5.00 1-2.5s Routine 1 x / Week 1x / 4 Weeks None 4.01 4.50 1-2.0s Incr Freq 1 1x / Week 2 x / Week 1x / 2Weeks 3.51 If Margin for Error is 4.00 1-2.0 Incr Freq 2 1x / Week 3.01 3.50 1-2.0s Incr Freq 3 2x / Week 1x / Week lower/worse than peers 2.51 3.00 8 1-2.0s Incr Freq 4 1x / Day 2x / Week Yes! Make it better. 2.00 2.50 X Stop! NO NOT report any results until acceptable quality is verified (Total Error < TEa) Investigate, take action and repeat prior patients as stated in Process # Q-111 This is ONE possible QC strategy plan. Approve or modify this before implementing! 30 Lev1: Lev2 Combinations - 8 Tests in 6 Labs Process to select Q.C. Strategy 1. Define the true value for each sample as per lab policy/hierarchy Compare Sigma Lev 1 Lev 2 2. Set the TEa limit for each sample as per lab policy/hierarchy 14 Lev 1 3.1 3. Gather recent mean & SD of all Q.C. Samples 12 Lev 2 6.9 4. Calculate Sigma for each sample 10 5. Select Q.C. Strategy for each sample based on Sigma Value 8 JNO Level 2 Why use separate strategies at each level? Change can occur at one level and not the other Check the graph. Sigma of Lev 2 is seldom the same as Lev 1 O No single strategy works for a test where Lev 1 Sigma is 2.1 and Lev 2 is 6.9 10 15 How can you implement separate strategies at each level? Level 1 It's not difficult. See details in FAQs at www.awesome-numbers.org (c) Zoe C. Brooks 1995 -2013 94
