Documentation Practices That Impress Inspectors

During an inspection by regulatory authorities, various documentation reveal the working of a pharmaceutical facility. Although inspectors spend only few hours on the production site, they spend days scrutinizing batch reports, logbooks, evaluation documents and quality assurance documents. This documentation indicate whether processes have been implemented correctly and scientific rationale of decisions and whether employees follow internal guidelines regularly.

Many companies presume that inspectors want to see perfect documentation. However, experienced inspectors want to see exactly the opposite: genuine, thorough and reliable documentation. A document containing a rectified error provided with appropriate explanation and signature is more credible than an impeccable document.

Over the years, I have witnessed how inspectors form their opinion on the quality culture of an organization during the first hours of the review of documents. Properly maintained records, logical investigations and validity of documents all indicate that GMP is employed daily and not perceived merely as a bureaucratic procedure.

Documentation Shows Quality Culture

High-quality documentation isn't just the responsibility of QA assistance. Each operator, technician, investigator and manager ensures the integrity of all quality related documentation. Inspectors usually check out the level of development of the quality assurance system by asking simple questions:

• Is the recording of the process done immediately?
• Are all decisions supported by proofs?
• Are all changes visible?
• Is the history of each event available for checking?
• Does the documentation testify to the know-how?

Once the documentation answers the questions above, inspectors will be assured of the quality assurance system used.

Prepare Records in Real Time

There is nothing that raises suspicions more than documentation that is done long after the activity itself took place.

Records of batch production, cleaning, inventory, environment measurements and laboratory analysis shall be filled in right after the process. Real-time systems of documentation present a number of benefits:

• They help to avoid mistakes in figuring
• They increase document tracing
• They ensure integrity of data
• They support compliance with standards
• They reduce dependence on memory

Once the information is reconstructed after some time passes, even the right information will be hard to explain during an auditing.

Every Entry Should Tell a Complete Story

Good documentation enables another qualified person to learn exactly what happened without the need to ask any further questions. Each record should answer:

• What work was performed?
• Who performed it?
• When was it performed?
• What equipment or materials were used?
• What result was obtained?
• Was there a deviation?

Incomplete documentation can provoke unnecessary questions during inspections.

For instance, saying "Equipment has been cleaned" does not communicate a great deal of information. A good entry would read:

• ID of the equipment
• Cleaning procedure number
• Cleaning agent
• Completion time
• Signature of the operator

Small details significantly improve record quality.

Make Corrections Transparent

Mistakes can happen in any facility. Inspectors do not expect perfect documentation, but they do expect corrections to be made transparently. To make corrections on documentation:

• Draw a straight line on top of the erroneous entry
• Ensure the original text can still be read
• Write the correct entry
• Write the date and put initials next to the correction
• When necessary according to the company's procedures, give the reason for the correction

Do not:

• Use any correction fluids
• Erase written content
• Cover the erroneous entry with illegible letters
• Tear off pages from controlled documents

Transparent corrections indicate integrity and compliance with Good Documentation Practices (GDP).

Maintain Logical Document Flow

The inspectors review several records at once. For example:

• Batch Manufacturing Record
• Equipment Logbook
• Cleaning Record
• Calibration Certificate
• Environmental Monitoring Report
• Analytical Results
• Batch Release Documentation

Having all the records interlinked is essential.

If, for example, cleaning of the equipment was recorded after the manufacturing process began, the inspectors are going to be suspicious of the documents’ accuracy. Consistency leads to the integrity of the data.

Making Scientific Decisions Clear

In documenting decisions, the documentation has to include the rationale for making such decisions too.
The document is particularly important in cases involving:

• Deviations
• Corrective And Preventive Actions (CAPAs)
• Change controls
• Out of specifications (OOS) investigations
• Validation reports
• Risk assessments

For example, it is not enough to write, "Investigation completed. No impact."

Provide scientific justification such as:

• Analysis of the batch history
• Trend analysis,
• Process capability analysis,
• Confirming analytical results,
• Conclusion from risk assessment.

Inspectors prefer fact-based rather than unsupported conclusions in any documentation.

Standardize Documentation Across Departments

The process of standardizing documentation practices can be very important in ensuring consistent GMP standards in operation processes.
For instance,

Production department dates may appear thus:
31/07/2026

The Engineering department may write:
July 31, 2026

And laboratory records may indicate dates like this:
31th of July, 2026

The meanings conveyed by these dates would be the same, but different date formats would complicate the document review process.

By standardizing following document entries, a decent, ordered documentation system is created.

• Formats of dates
• Formats of time
• Identification of equipment
• Names of products
• Abbreviations
• Signature practices

Build Data Integrity into Every Record

Currently, inspections place more importance on data integrity than documentation alone. The standards of ALCOA+ have been defined by inspectors to make sure that records comply. Documentation should have the following characteristics:
1. Attributable
2. Legible
3. Contemporaneous
4. Original
5. Accurate
6. Complete
7. Consistent
8. Enduring
9. Available
Regardless of using conventional or advanced systems, this features always exist in the documentation cycle.

Make Sure all Documents are Easily Available

The prompt document retrieval is one of the main traits common to inspection-compliant organizations. When the inspectors ask for following:

• Validation protocol
• Batch record
• Cleaning SOP
• Calibration certificate
• Change control
• Training record

The documents have to be found in a few minutes instead of several hours.

Slow response usually leads to the conclusion that documents are not controlled properly. Many production companies have a document library and a checklist of inspection documents which facilitate rapid retrieval of documents.

Avoid Common Documentation Weaknesses

There are many mistakes in documents cited in the inspection reports.
For instance:

• Some sections are not marked in the document
• Signatures are often missing
• Dates are often not given
• Changes in the document are made without explanation
• Writing is not readable
• Terminology is not consistent
• Investigation reports are not completed
• Findings have no evidence
• Attachment is missing
• Several versions of the same document

Each of the mentioned problems looks small but they all suggest poor document control.

Use Trending to Strengthen Documentation

Proper documentation should not just be filed once it is accomplished. Quality assurance units should re-evaluate documents periodically to identify any ongoing trends which relate to issues that occur repeatedly. Some examples include:

• Repeated errors with documentation.
• Repeated deviations.
• Repeated failures of equipment.
• Similar items requiring corrective and preventive action (CAPA).
• Similar conclusions from investigations that were carried out.
• Repeated mistakes made by operators.

The analysis of trends allows one to identify systemic weaknesses that could be found by inspectors later on.

Train Employees to Document, Not Just Perform

Most companies emphasize training the staff in manufacturing operations and neglect other aspects of document management. Employees have to know:

• The significance of documentation.
• How records are evaluated by inspectors.
• GDP specifics.
• Requirements regarding data integrity.
• Proper documentation practices.
• How to deal with documentation mistakes.

Proper documentation is a skill that should be enforced.

Documentation at the Time of Inspection

When the inspectors ask for any documents:
- Only give the required documents.
- Make sure that all the documents are full.
- Go through the copies before giving them the documents.
- Do not give hand-written explanations unless you are asked for it.
- Do not change the document after the inspection is conducted.
- Give the documents in an orderly fashion.

In case there is a mistake in a document, explain it honestly and do not try to diminish its role. Generally, inspectors appreciate honesty more than defensiveness.

What impresses inspectors the most?

From my experience, the inspectors are hardly impressed by the costly document software and recall the elaborate document formats. What helps them earn trust is the ability of the document not to fail.

The records that inspire confidence are:
- The documents are written in real-time.
- The scientific basis is clearly available.
- The corrections made are clear.
- The documents are traceable.
- Consistency across departments.
- The documents are linked to each other well.
- Effective control of document revisions.
- Ready availability during inspections.

 
These characteristics reflect a developed pharmaceutical quality system rather than a company getting ready specifically for an inspection.

The documentation is among the most potent indicators of the status of the GMP culture in any organization. Each batch record, log, report and investigation shows the inspectors how the work is planned, executed, reviewed and controlled. Properly kept records show discipline, science and working according to the requirements of the regulations, while unwitnessed or undisrupted documentation is enough to demolish the trust in the quality system.

In my experience, the companies doing well during the inspections of authorities view the documentation as an integral part of the manufacturing process rather than the procedure of administration. The timely documentation that is evidenced and dignified will not only comply with the regulations but also serve as a tool for permanent improvement of the process.
