The problem with patient based QC

CPPP.edp

In an editorial (actually more of a mini review) in Clinical Chemistry, the various patient based QC methods are reviewed. The editorial is provided because of a companion article that has yet to appear.

One problem with patient based QC is that it is always compared to traditional QC, perhaps with the goal that it could replace traditional QC. But why not do both.

And perhaps a bigger problem is that people study patient based QC by performing simulations and/or providing examples showing that retrospective analysis of a (known) problem (perhaps a clinician complaint) would have been detected by patient based QC.

But I am not aware of anyone routinely using patient based QC (with or without traditional based QC), for all assays.
