Objective of the inspection
Routine inspection
Concise inspection
Follow-up inspection
Special inspection
Quality systems review
The objective of the inspection influences the inspector’s planning, organization, method of work, and the format of the report that will be written after the inspection.
Different types of inspections can be performed depending on the objective of the inspection.
Types of inspections identified in the WHO text, include:
Routine inspection
Concise inspection
Follow-up inspection
Special inspection, and
Quality systems review.
Let’s look at each of these types of inspections in more detail.

4. Types of GMP Inspection
World Health Organization
12 January, 2019
Routine Inspection
Full inspection of all components of GMP
Newly established manufacturer
Renewal of a license
Changes:
 new product or product lines
 modifications to manufacturing methods
 key personnel, premises or equipment
History of non-compliance with GMP
Not inspected in the last 3-5 years
A routine inspection is a full review of all aspects and components of GMP within a facility. The inspector should also be aware of the licensing provision. Routine inspections may be announced or unannounced, depending on the history of the company, previous inspections and the policy of the country.
It is appropriate to perform a routine inspection under the following circumstances:
When there is an application for a new manufacturing license for a newly established manufacturer
When a manufacturing license is due for renewal.
If there have been significant changes such as new products or new product lines, modification to manufacturing methods or processes, or changes in key personnel, premises, and or equipment.
If the company has an history of non-compliance with GMP.
If an inspection has not been carried out within the past 3–5 years.

5. Types of GMP Inspection
World Health Organization
12 January, 2019
Concise Inspection
Consistent record of compliance with GMP
Focus on limited number of GMP requirements
selected as indicators
Identify significant changes
Indicate attitude towards GMP
Non-compliance
should trigger comprehensive inspection
A concise inspection is the evaluation of limited aspects relating to GMP compliance within a facility. (It is known as an abbreviated inspection in some countries.) A limited number of GMP requirements are selected by the inspector to serve as indicators of overall GMP compliance by the manufacturer. The inspector also has to identify and evaluate any significant changes that could have been introduced by the manufacturer since the last inspection.
Collectively, the selected indicators and identified changes indicate the manufacturer’s attitude towards GMP.
Depending on national practice, a company would normally not be warned in advance about a concise inspection.
A concise inspection is applicable under the following circumstances:
Where a manufacturer has a consistent record of GMP compliance through routine inspections in the past.
Where a sample of aspects can be taken as a good indication of the overall level of GMP compliance.
However, if the concise inspection uncovers evidence that the level of GMP compliance has fallen, a more comprehensive or full GMP inspection should then be performed soon after the concise inspection.

6. Types of GMP Inspection
World Health Organization
12 January, 2019
Follow-up Inspection
Reassessment or re-inspection
Monitor result of corrective actions
6 weeks to 6 months after initial inspection
nature of defects
work undertaken
Specific GMP requirements
not observed
not adequately implemented
A follow-up inspection is also referred to as a re-inspection or a re-assessment of the manufacturer.
A follow-up inspection is performed specifically to monitor the result of corrective actions of the manufacturer following a previous inspection. The manufacturer would not necessarily know in advance about the follow-up inspection.
Depending on the nature of the defects and the work required, the follow-up inspection could be carried out between 6 weeks and 6 months after the original inspection had taken place.
The inspection is limited to specific GMP requirements that have not been observed or that have been inadequately implemented by the manufacturer.

7. Types of GMP Inspection
World Health Organization
12 January, 2019
Special Inspection
Spot check focusing on
one product, a group of related products
specific operations, e.g. mixing, labelling
Complaints or recalls
Adverse drug reactions
Marketing approval or export certificate
Information or investigation
specific information
advice on regulatory requirements
There are a number of circumstances in which special visits or inspections may be necessary. A special inspection is undertaken to do spot checks. Spot checks could focus on one product, a group of related products, or specific operations e.g. mixing, or labeling.
The manufacturer may or may not be aware in advance of the inspection, depending on the reason for it.
If there have been complaints about a specific product that suggest there may be defects, then a special inspection could be performed to investigate the quality defects of the product. It is unlikely that the company would be warned in advance in this case.
If there has been a product recall, this can also trigger an inspection, as would adverse drug reactions.
In the above cases, the inspection would focus on the specific product or aspect of production that is suspect.
An application for a marketing authorization or an export certificate may also trigger such an inspection.
A special inspection could also be performed to gather specific information, or to investigate specific operations of the manufacturer. In some cases, this opportunity is used to advise the manufacturer on specific regulatory requirements.
(The trainer should provide specific examples of “special inspections” e.g. after receiving a complaint, etc)

Quality Systems Review
Assess the quality assurance (QA) system
Description of the QA system (e.g. manual)
Policy and standards to be observed
Management structure
implementation
Procedures
quality standards set for products
correctly defined manufacturing processes
records kept
QC and QA functions are performed
The purpose of a quality systems review is to review the manufacturer’s quality system and to describe whether that has been shown to operate satisfactorily.
The quality systems manual is a document describing the quality systems and the standards to be observed. It also includes the entire operational process, and the quality management policy and quality assurance approach of the manufacturer.
The manual reflects the process of implementation of the quality policy, keeping of records, quality control and other quality assurance activities.
This type of review is similar to that which is carried out when a manufacturer is applying for accreditation, e.g. international standards (ISO 9000).

Frequency of Inspections
Depends on type of inspection
Inspectorate resources (e.g. workload, number of inspectors)
New facilities - before licensed
All companies - regular schedule
ideally annual
Large companies
several visits over a period, e.g. 5 years
validity of manufacturing license or GMP certificate
Although there are ideal timetables that should be achieved for inspections, in practice there are a number of factors that influence the frequency of inspections. These are:
- The type of inspection being undertaken.
- The number of inspectors available and their workload.
- The number of companies to be inspected.
An ideal timetable would be an annual inspection of each manufacturer.
The size of the manufacturing site will also influence the frequency of inspection. A large company with a wide range of products and several major departments may be inspected in a number of stages over a time period taking cognisance of the period of validity of the manufacturing license or GMP certificate.

Duration of Inspections
Depends on type of inspection
Inspectorate resources (e.g. workload, number of inspectors)
Size of the company
Purpose of the visit
Days to weeks
Number of inspectors
including specialist support
The length of an inspection is determined by a number of factors, including the type of inspection to be performed, the number of inspectors, the size of the company and the purpose of the inspection or visit.
An inspection can be performed over a period of a few days to several weeks.
The time taken will also depend on the size of the inspection team. One or more inspectors can perform the inspection and the inspector(s) may request a specialist to accompany them during the inspection. Depending upon the area or specific aspects to be inspected, a specialist could provide specialist support to the inspection team. This can be very helpful in certain cases, e.g. the manufacture of biologicals.

Announced and unannounced inspections
Depends on type of inspection
Announced
comprehensive inspection
Unannounced
routine inspection (depending on country policy)
concise inspection
follow-up inspection
special inspection
Inspectors have to decide whether the inspection to be performed, will be announced or unannounced.
This is dependent on the type of inspection, and the policy of the regulatory authority.
A comprehensive inspection can be announced or unannounced.
Concise inspections, follow-up inspections and special inspections are normally unannounced.

Regulatory Actions
Based on national regulations
Correction of unsatisfactory situations
Closing down of a factory
Withholding of authorizations
Product recall
The inspectorate of a regulatory authority normally has certain powers to allow for regulatory actions. The regulatory actions are based on and controlled by national legislation
The purpose of the regulatory action is to ensure that unsatisfactory situations in manufacturing sites are corrected in the interest of the public by ensuring that safe, effective, quality pharmaceutical products are manufactured.
These powers or regulatory actions often include:
- Closure of a facility (only used in an extreme case where a health hazard is perceived)
- Suspension or revoking of the marketing authorisation.
- Delay in approval of licenses or marketing authorisations.
- Delay in issue of a GMP certificate.
- Initiation of a product recall.

Group Session
The inspectorate received a complaint that an injectable product (water for injection (WFI), 10ml ampoule) is possibly contaminated with microorganisms. You have to organize an inspection of the company in question
What type of inspection would be performed?
Will the inspection be announced or unannounced?
Who will be part of the inspection team?
What will you consider in preparation for the inspection?
We will now move into syndicate discussion.
In your groups, discuss the situation in which 5 deaths are known to have occurred due to pseudomonas-contaminated WFI.
Who would you take with you?
What objectives would you have?
Would you announce your visit?
What actions would you take?

14. Types of GMP Inspection

Possible Issues
Purpose of the inspection
Notification (or not) of the company in advance
Make-up of the team
Programme for the inspection
Sterility test, leak test and visual inspection
Validation and qualification
Documentation review
The organization of the inspection will depend on the purpose - initial, routine, follow-up, concise etc.
Whether the company is informed of the intention to inspect will depend on the purpose of the inspection and also on common practice within the country.
Depending on the nature of the inspection, there will be times when the inspection team will not have all the necessary expertise and will need to bring in a specialist. For example, in the pseudomonas question, it might be necessary to involve a microbiologist to review sterile procedure or an engineer to review the design of the facility.
Although there will be a programme developed before the inspection begins, it will often be necessary to revise that programme in the light of initial findings. Inspectors should be flexible enough to adapt the programme if necessary, but should also ensure that they are not deflected from their objectives by the company being inspected.
