Introduction:
Patient-based real-time quality control (PBRTQC) is an attractive addition to a laboratory's quality assurance program. However, implementation for clinical chemistry analytes has been lacking. To assist with broader implementation, provided is PBRTQC protocols from a large hospital laboratory along with over 7 years of tabulated experience.
Materials And Methods:
PBRTQC was initialized and monitored for 17 clinical chemistry analytes utilizing Data Innovations middleware. Gathered results include total alerts, true alerts, and true alert rates by year and analyte.
Results:
Overall, there were 623 total alerts and 160 true alerts resulting in true alert rate of 25.7%. The true alert rates ranged from 0 to 100%, depending upon the analyte.
Conclusions:
PBRTQC provides a low/no cost tool providing real-time detection of systemic bias. Implementation assists the laboratory in providing high-quality results.
