Consultancy Services for Autoverification Rules Setup: Hematology, Chemistry, Urinalysis, AP
OFF-LINE (Logic Tests)
- Validate proposed rules by analyzing test data: input data having the following expected outputs:
- Release result as is
- Hold result
- Change result and release
- Change and hold
- Add comments/codes
- Check internal consistency of rules.
- Contradictions/Conflicts
- Cancellations
- Determine coverage that rules provide.
- All data conditions accounted for?
- Redundant rules
- Non-applicable rules
ON-LINE (Effectiveness Tests) using instrumentation interfaced to any Middleware/LIS/LIMS/EMR vendor.
Evaluate rules with respect to:
- Accuracy of reported results
- Questionable/incorrect instrument-based or manually entered results
- Ability to flag abnormal results and distinguish from inaccurate results. Use:
- Available instrument redundancies: e.g. 2 WBC counts
- Instrument flags
- Recorded tech visual observations
Determine most effective follow-up actions for rule violation.
- Impact of different actions on accuracy and TAT; e.g. rerun vs. slide review
- Impact of rules + follow-up actions on TAT
- Review rate per rule
- % of cases that rules-based actions cause changes to previous results
Monitor instrument/technician productivity, and reveal method and/or reagent problems.
- Samples processed per hour per tech, e.g. manual differentials
- Instrument throughput per sample per hour
- Instrument throughput per test per hour
- # QC fails by instrument/parameter/Westgard rule
LabThruPut analytical tools are available to retrospectively analyze data using current and altered rules to determine the changes’ impact on review rates, result accuracy, and TAT.
- Filter data by e.g. site, instrument, demographic, date/time range.
- Significantly shorten typical rules optimization process from months to days.
