The impact of QC frequency on patient results.

چکیده
The expected number of unacceptable patient results due to an undetected, malfunction--E(Nu)--can be set as a patient-based quality goal. Using the number of patients tested between QC specimens as a design parameter allows one to design QC strategies that meet specified patient-based quality goals. The QC utilization rate can be minimized in a QC design for a given E(Nu). The QC-utilization rate achievable depends on how close analytical imprecision is to the total allowable error.

Assessing the impact of the frequency of quality control testing on the quality of reported patient results.
BACKGROUND The traditional measure used to evaluate QC performance is the probability of rejecting an analytical run that contains a critical out-of-control error condition. The probability of rejecting an analytical run, however, is not affected by changes in QC-testing frequency. A different performance measure is necessary to assess the impact of the frequency of QC testing. METHODS I used...
