Investigating Out of Specification (OOS) Results

15 December 2022 09:00 - 16 December 2022 12:45

This course is designed to be an exploration of best practice for OOS investigations in a GMP environment.

The course is aimed at the investigation of all out of expectation (OOE) results, including out of specification (OOS), out of trend (OOT) and any atypical, aberrant or anomalous results. For convenience, the term OOS is used in the following information, but all OOE results will be covered in the course.

Course overview

The course explores the process for investigation of OOS results and the different phases of investigation, and also best practice investigation skills for effective and scientific OOS investigations. This includes:
  • Following a scientific rationale,
  • The expectations of regulatory authorities,
  • Gathering available evidence,
  • Generating potential hypotheses,
  • Testing those hypotheses,
  • Interpretation of hypotheses testing using appropriate statistical tools,
  • Performing root cause analysis, using appropriate and effective tools and techniques.

Learning Objectives

  1. Comprehend the significance of investigating OOS results effectively.
  2. Understand the process for investigation of OOS results through the phases defined by regulatory authorities such as FDA and MHRA.
  3. Formulate appropriate hypotheses regarding potential assignable causes for OOS results.
  4. Conduct effective and scientific OOS investigations
  5. Effectively evaluate the data resulting from OOS investigations using appropriate techniques and tools.
  6. Perform root cause analysis for laboratory failures which lead to OOS results and design relevant CAPAs to prevent reoccurrence.
Attendees are invited to bring along any real life examples that they would like advice on during the training. These may be discussed during group exercises, or, where intellectual property is an issue, privately with the trainer.

Course Delivery

This course is suitable for

Anyone who is involved in an OOS (or similar) results investigation, including those who are responsible for leading the investigation. The focus of the content is on the analytical aspects of the investigation, rather than manufacturing.
For example:
  • Quality Control (QC) analytical chemists
  • Quality Control (QC) managers/ supervisors
  • Quality Assurance personnel

Included in the course fees

  • Comprehensive course hand-outs - The training book is provided as an electronic copy (pdf) for both live online and classroom based options.
  • Certificate of Attendance
  • Optional post training assessment (accessed in e-MTS, our learning management system) which leads to a Certificate of Training.
  • Access to training materials via e-MTS
  • Post training support – Attendees can contact the trainer with questions that may occur when they apply their learning to real life situations.
