  Estimating and Comparing Diagnostic Laboratory Performance with Weighted Estimating Equations
  Author(s): Patricia Cooper Barfoot*, Stefan H. Steiner and R. Jock MacKay
  
  Patient test outcomes from diagnostic testing laboratories can be indicators of laboratory performance. One method of proficiency testing compares test results across laboratories to flag non-compliant laboratories. Under this type of proficiency test, the statistical approaches for estimating the test result and comparing these across laboratories have important implications. The proficiency test of fecal occult blood testing laboratories in Ontario compare estimates of pass rate for a particular test by laboratory based on data observed in the present (latest) month. Estimates by laboratory are compared to an acceptance interval determined by data across all laboratories. A laboratory is classified as non-compliant when its monthly rate is outside the acceptance interval. We note that monthly sample sizes have an important impact on the probability that a laboratory is classified in.. Read More»
