Repeating Critical Hematology and Coagulation Values Wastes Resources, Lengthens Turnaround Time, and Delays Clinical Action

Abstract

OBJECTIVES: To determine the need and impact of repeating critical values in hematology and coagulation. METHODS: We prospectively evaluated the need for repeating critical values. The cost of this practice was estimated using a workflow analysis. Retrospective chart review before and after removal of this process was performed to assess the clinical impact of removing this practice. RESULTS: Over 95% of the repeated values remained critical and all but one of the repeats were within the expected analytical precision of the assays. The practice of repeating critical values delayed turnaround time for these results and wasted resources, most notably manpower. The delay associated with repeating hematology critical values resulted in delayed administration of blood product (RBC units). CONCLUSIONS: Repeating critical hematology and coagulation results was found to be an unnecessary process that wasted laboratory resources and lengthened turnaround time, delaying clinical intervention.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
