Reading the mock tracer file

The testing person was hired 14 months before the inspection date. On the prior, now-retired, analyzer, competency was documented at 2 and 7 months after hire, the semiannual first-year pattern, all six procedures checked off and signed by the technical consultant. An annual competency assessment on that same prior analyzer was documented again at month 13, also with all six procedures present. So far, this file shows a laboratory doing competency assessment correctly, on schedule, for the test system that was in use.

The new analyzer went live six weeks before the inspection, at roughly month 12.5 on this employee's timeline. A training record exists: a three-hour vendor in-service, signed in one week before go-live. That satisfies the expectation that testing personnel be trained before testing begins on a new instrument, but training is not itself a competency assessment. What the file does not contain is any six-procedure competency assessment dated for the new analyzer.

QC on the new analyzer, two levels every shift this employee worked since go-live, has all been in range and reviewed weekly by the technical consultant. One PT event for the applicable analyte on the new analyzer has come back satisfactory, filed with a technical-consultant review signature. Both are real evidence of quality performance, and neither is a substitute for the missing competency record: CMS guidance is explicit that testing personnel must be trained and demonstrated competent before reporting patient results on a new methodology or instrument, and that the assessment does not carry forward from a retired test system.

The missing element, stated precisely, is a documented, dated six-procedure competency assessment specific to the new analyzer, performed by the technical consultant, the role responsible for moderate-complexity testing personnel. This is a real gap in the operating system, not a paperwork technicality, because the analyzer changed and the requirement resets with it. When a test system changes, ask for the new competency record by name before you accept QC and PT as reassurance that the old one still counts.

Ordering exercise

Put this employee's record events in chronological order, earliest first, the way the inspector reads the file during the tracer.

  1. 1. Annual competency, prior analyzer

    Documented at month 13, before the switch was complete for this employee.

  2. 2. New analyzer go-live

    Six weeks before the inspection date.

  3. 3. Hire date

    The employee's start date in the section.

  4. 4. Vendor training, new analyzer

    Three-hour in-service, one week before go-live.

  5. 5. Second semiannual competency, prior analyzer

    Documented 7 months after hire.

  6. 6. First semiannual competency, prior analyzer

    Documented 2 months after hire.

Knowledge check 1

In the mock tracer file, QC is in range, one PT event is satisfactory, and training occurred before go-live. What single element is still missing before this employee should test independently on the new analyzer?

Choose one option.
