Pharma Industry Interview Question & Answer Part 06 (ERES)

 


Question 01: 

If you use Electronic Signatures, do you have to comply with Electronic Record Requirements?

Best Answer: Use of Electronic Signatures implies that your system is an Electronic Record system and, therefore, must be in compliance with all provisions of 21 CFR Part 11.

Question 02: 

Are electronic signatures always required on the creation of electronic records?

Best Answer: The ‘Predicate Rules’ (GxP) regulations determine what records must be signed, not Part 11. Not all e-records need to be signed.
Check your predicate rules for what records must be signed, when and by whom.
 

Question 03: 

Does Part 11 apply to instruments themselves that are not connected to computers but that have microprocessors within?

Best Answer: If such a system does not generate electronic records according to the definition of e-records in Part 11 (data starting its life written to durable media), and/or these e-records are not subject to the GxP regulations, then Part 11 does not apply.
 
 
Question 04:
 
Does Part 11 apply to electronic systems that can print records but do not have a durable storage media (i.e. flash memory or memory buffer, etc.)?

Best Answer: 
The question is really not that much for the storage media, it’s more whether the operator can manipulate the data before they are printed.
The real problem is that most of this equipment does not have functions required by part 11.
 
 
 
Question 05: 

I keep electronic records but have signatures on paper (hybrid systems). Is there a deadline for converting to electronic signatures?

Best Answer: No. There is no deadline for converting to electronic signatures. Having handwritten signatures on paper is acceptable if signature are linked to electronic records so signers cannot repudiate records.
 
Question 06: 

How long must data concerning electronic signatures be kept?
What data? 

Best Answer: The signed data may no longer be separated from the signature. Signature and signed data must be kept for an equal period of time.
 
The retention period to be specified must be defined according to the underlying requirements, such as GxP requirements (other requirements may also be relevant: commercial law, liability law etc.). 
Data concerning the undersigned has to be kept at least as long as the signed data (data concerning the undersigned is in fact metadata of the signed data).
 
In any case, the user data should be kept as long as the system is operated and as long as the signed data must be kept.
 

Question 07: 

Can a single restricted login suffice as an electronic signature?

Best Answer: No. The operator has to indicate intent when signing something, and he has to re-enter the user ID/password (shows awareness that he is executing a signature) and give the meaning for the e-sig.

To support this, Part 11 §11.50, states that signed e-records shall contain information associated with the signing that indicates the printed name of the signer, the date/time, and the meaning, and that these items shall be included in any human readable form of the record.
 
Question 08:
 
When are e-signatures required?

Best Answer: 
The predicate rules mandate when a regulated document needs to be signed.
 
Question 09:
 
Should a company individually certify that every associate’s electronic signature is legally binding?

Best Answer: 
No. The required one-time e-sig certification is for an organization as a whole. Its intent is to certify that a company recognizes that its e-signatures are equivalent to their hand-written signatures.
 
Question 10:
 
What do you mean by linking e-records to e-signatures?

Best Answer: 
Part 11 Sec. 11.70 states that electronic signatures and handwritten signatures executed to electronic records must be linked (i.e. verifiably bound) to their respective records to ensure that signatures could not be excised, copied, or otherwise transferred to falsify another electronic record.

The agency does not, however, intend to mandate use of any particular ‘linking’ technology. FDA recognizes that, because it is relatively easy to copy an electronic signature to another electronic record and thus compromise or falsify that record, a technology-based link is necessary.

The agency does not believe that procedural or administrative controls alone are sufficient to ensure that objective because such controls could be more easily circumvented than a straightforward technology based approach.
