Handling OOS
Investigations
Ershad Moradi
Phase I:
Laboratory
Investigation
In this phase, the analyst and
supervisor are responsible for
identifying and documenting
any deviations from standard
operating procedures that
may have contributed to the
OOS result.
Analyst
Responsibilities
The analyst should thoroughly
review the data, ensure that all
calculations are accurate, and
report any anomalies to their
supervisor.
Supervisor
Responsibilities
The supervisor should provide
guidance to the analyst,
review all documentation
related to the OOS result, and
initiate the investigation
process.
Phase II: FullScale OOS
Production
Review
In this phase, a comprehensive
review of the production
process is conducted to
identify any potential factors
that may have contributed to
the OOS result
Production
Personnel
Responsibilities
Production personnel should
provide input on potential
causes of the OOS result and
work closely with the
laboratory team to gather
relevant information.
Quality Control
Responsibilities
The quality control team is
responsible for ensuring that
all production processes are in
compliance with regulatory
requirements and that proper
documentation is maintained
OOS Additional
Laboratory
Testing
In some cases, additional
laboratory testing may be
required to confirm the OOS
result or identify any potential
errors in the initial analysis
Sample
Retesting
Sample retesting should be
conducted using the same or
an alternative analytical
method to verify the accuracy
of the initial results
Investigation
Protocol
A detailed investigation
protocol should be developed
to guide the investigation
process and ensure that all
relevant factors are considered
Root Cause
Analysis
A thorough root cause analysis
should be conducted to
identify the underlying factors
that contributed to the OOS
result.
Corrective
Actions
Based on the findings of the
investigation, appropriate
corrective actions should be
implemented to address any
deficiencies in the production
process
Preventive
Actions
In addition to corrective
actions, preventive measures
should be put in place to
prevent future occurrences of
OOS results
Documentation
and Reporting
All findings and actions taken
as a result of the OOS
investigation should be
properly documented and
reported to relevant
stakeholders
Regulatory
Compliance
It is important to ensure that
all OOS investigations are
conducted in compliance with
regulatory requirements and
guidelines
Communication
with
Stakeholders
Clear and effective
communication with all
stakeholders, including
regulatory bodies, is essential
throughout the OOS
investigation process
Training and
Development
Ongoing training and
development programs
should be implemented to
ensure that all personnel are
equipped to handle OOS
investigations effectively
Continuous
Improvement
Regular review and
assessment of the OOS
investigation process should
be conducted to identify
opportunities for
improvement
Lessons
Learned
It is important to learn from
each OOS investigation and
apply those lessons to future
investigations to prevent
similar issues from occurring.
Conclusion
It is important to learn from
each OOS investigation and
apply those lessons to future
investigations to prevent
similar issues from occurring.
