Terminology ¢ ¢ “Quality Control” has always been a part of the clinical laboratory, Terminology ¢ ¢ “Quality Control” has always been a part of the clinical laboratory, but had been used exclusively for analytical activities. QC is designated to ensure the medical reliability of lab data. We now know that we must analyze pre -analytical, and postanalytical activities and the terminology is NOW called “Performance Improvement” (PI)

Indicators/Monitors of Performance Improvement ¢ ¢ Process Monitors l Results are complied and evaluated Indicators/Monitors of Performance Improvement ¢ ¢ Process Monitors l Results are complied and evaluated routinely, allows for identification of disruptions Outcome Monitors l Measurements as a result of processes Focus Monitors l Initiated in response to a suspected problem Benchmarking l Seeking an industry’s or profession’s best practices l Helps provide a starting point for improvement
