[QUOTE=Rashmi;5616]I am trying to gather info for future LIMS changes and recently a colleague mentioned that while their Grouping data was migrated to the new LIMS, this was a Read-Only copy, therefore the delta checking function wouldn’t work against this data ( ie wouldn’t alert if the group of a new sample was discrepant).

The impact of this set up would be:
1) all requests for blood would have to be serologically cross-matched, as EI criteria not met as only one recognised group on LIMS (until a second sample tested).

2) increased cross-matching for at least a few months- is this considered as part of resourcing- 24/7 workload ?

3) process for authorising all G&S tests would have to change- with a manual check against the historical read-only data- again for what length of time would this continue?

Considering the number of wrong blood in tubes that are recorded by SHOT and detected by the LIMS delta check rules, actively checking the history of every sample during authorisation would additionally affect sample TATs.

I’m sure there are colleagues out there that have already changed LIMS- please advise if some systems are capable of delta checking against the migrated data, or if the above is routine.

Many thanks!

Hi Can you please provide me with more details on this via E Mail michael.dawe@mhra.gov.uk. This issue should have been captured within the User Requirement Spec (URS) where a site should state that migrated data is essential in selecting patients for EI and to identify WBIT etc, as stated in the previous post, and therefore a delta check was an essential requirement.
