A hospital laboratory consultant reviews turnaround time (TAT) data and finds STAT troponin results average 87 minutes, exceeding the 60-minute benchmark. Which action should be prioritized first?
Answer: Perform a workflow time-motion study to identify bottlenecks
A time-motion study identifies the root cause of TAT delays before committing resources to a solution.
A laboratory consultant is asked to evaluate whether to bring microbiology culture testing in-house from a reference lab. Which financial metric is most critical to assess first?
Answer: Break-even volume analysis
Break-even volume analysis determines how many tests must be performed to justify the capital and operational costs of in-house testing.
During a CLIA inspection preparation, a consultant discovers that the laboratory has been using reagents 3 weeks beyond the manufacturer's expiration date. What is the immediate corrective action?
Answer: Remove expired reagents, quarantine affected results for review, and implement an expiration monitoring log
Expired reagents must be immediately removed and affected results reviewed to ensure patient safety and regulatory compliance.
A consultant evaluating a physician office laboratory (POL) finds that a waived-test glucose meter lacks any quality control documentation for the past six months. Under CLIA, what is the correct classification of this deficiency?
Answer: Condition-level deficiency
Failure to perform manufacturer-recommended QC on waived tests is a condition-level deficiency under CLIA that must be corrected.
A clinical laboratory consultant is analyzing staffing productivity metrics. The laboratory reports 1,200 billable tests per FTE per day. Compared to the MGMA benchmark of 900, what does this most likely indicate?
Answer: Understaffing with excessive overtime costs
A billable test per FTE significantly above benchmark typically signals understaffing, where staff are overworked to compensate for insufficient headcount.
A laboratory consultant is recommending a new middleware solution to consolidate results from six analyzers. Which capability is most essential for reducing manual result review?
Answer: Auto-validation rules based on delta checks and reference ranges
Auto-validation via delta checks and reference range rules allows middleware to release results without technologist review, directly reducing manual workload.
A consultant reviewing a laboratory's proficiency testing (PT) records finds two consecutive unsuccessful PT events for serum potassium in the same analyte. What is the required regulatory response under CLIA?
Answer: Cease patient testing for potassium until a root cause investigation is completed and documented
CLIA requires that testing for an analyte with two consecutive PT failures be suspended until the problem is identified and corrected.
