Double blind data entry will protects laboratory information management systems (LIMS) from typing errors, Autoscribe claims.
A result entry enhancement has been added to the Matrix Gemini LIMS from Autoscribe.
The double-blind entry capability allows the results from a test to be entered into the LIMS on two separate occasions and then checked against each other by the LIMS in order to minimise typing errors.
If the two values do not match, the user is warned and asked to pick the correct one.
It is particularly useful in clinical trial studies for patient data collection in conformity with CFR 21 part 11 data validation, Autoscribe says.
When a test is set up as a double blind test, the results fields appear empty, as normal.
Stage one values are entered and saved. Any value can be edited, which includes audit trailing, before the sample test is confirmed as having completed stage one.
Once this has been confirmed, the stage one results disappear and the stage two values can be entered and saved.
These may also be edited before confirmation of completion of stage two.
When stage two completion is confirmed, any conflicts are highlighted on a conflict resolution screen. Once all conflicts have been resolved the final values appear in the results fields. Calculations and limit checking are performed.
The conflict resolution screen allows the user to choose either value ’1’ or value ’2’ in any results field where there is a conflict. This screen may not be closed until all conflicting results have been resolved.
