Shared logins on a GMP system

Computerised systems: data integrity, access control

What the inspector wrote

The chromatography data system in QC laboratory 2 was accessed using a shared account 'QCLAB' whose password was known to all analysts. Electronic signatures applied under this account could not be attributed to an individual. The audit trail showed 214 result approvals under the shared account in the review period.

Cited against EU GMP Annex 11, 12.1 and 12.4; Chapter 4, 4.20

Why it was cited

Every data integrity principle rests on attributability. A shared account means no action in the system can be tied to a person, so the audit trail, the electronic signatures and the second-person review are all void at once.

Sites usually know this is wrong and do it anyway for convenience: licence costs, shift handovers, a legacy system. None of these are accepted as justification.

What would have prevented it

  • Unique accounts for every user on every GMP system, without exception, with role-based permissions.
  • Periodic user access review by QA, with evidence of leavers being removed.
  • Include audit trail review in batch and result review procedures, performed by someone other than the data originator.

Written from the deficiency categories published by EU and UK regulators. Details are illustrative and do not describe a specific named site.

'Human error' accepted as a root cause, again

Investigation of anomalies: inadequate root cause analysis

Deviation DEV-24-0187 concluded that the root cause was operator error and the CAPA was retraining of the operator concerned. The same failure mode had been recorded in three previous deviations in the preceding fourteen months, each with the same conclusion and the same corrective action. No assessment of contributing factors, procedure design or equipment had been performed.

The impact assessment that stopped at the batch

Deviation handling: impact on other batches not evaluated

A temperature excursion in cold store CS-02 was recorded as a deviation against batch 4471 only. Twelve other batches of four products were stored in CS-02 during the excursion window. No assessment of impact on these batches was performed and two of them were subsequently certified and distributed.

The change that went live before anyone approved it

Change control: change implemented prior to approval

Change control CC-24-031 to replace the filling machine PLC was raised on 14 March and approved on 2 April. Maintenance records show the PLC was replaced on 21 March and production resumed on 22 March. Three batches were manufactured on the modified equipment before the change control, including its validation impact assessment, was approved.
