What Do Inspectors Check for ICSR Medical Review and Assessment?

Pharmacovigilance systems must ensure ICSRs undergo medical review to confirm clinical accuracy, causality, expectedness, and case interpretation. Regulators expect structured medical assessment and documentation of clinical reasoning.

For: Founders, CEOs & MDs·PV Leads·QA/Compliance·Scientists tasked with documentation

Alignment: Global pharmacovigilance principles (ICH-aligned) and inspection practices

Most useful when: Preparing for inspection, setting up a process, or closing a documentation gap

Key points

  • ICSRs must undergo medical review by a qualified professional.
  • Medical review must confirm clinical accuracy, causality, and expectedness.
  • Assessment must consider patient history, product exposure, and alternative causes.
  • Clinical reasoning and conclusions must be documented.
  • Medical review should identify potential safety signals or escalation needs.
  • Inspection-ready evidence must demonstrate consistent and structured medical evaluation.

What inspectors expect

Each point below should be supported by controlled documents and traceable records.

  • ICSRs must undergo medical review by qualified personnel.
  • Causality and expectedness must be assessed and documented.
  • Clinical reasoning must be clearly recorded.
  • Medical review must consider confounding factors and alternative explanations.
  • Cases must be evaluated for potential safety signals.

Summary

Inspectors assess whether pharmacovigilance systems perform structured medical review of ICSRs. They typically evaluate causality assessments, expectedness determinations, clinical coherence, and documentation of medical reasoning.

Evidence objects inspectors expect

Medical Review Worksheet

  • Structured assessment of adverse events
  • Causality assessment and rationale
  • Expectedness evaluation against reference documents
  • Clinical interpretation of patient context
  • Medical reviewer comments and conclusions

Causality Assessment Documentation

  • Company causality assessment
  • Reporter causality comparison
  • Rationale for relationship assessment
  • Consideration of confounding factors

Expectedness / Labeling Assessment

  • Comparison of events against CCDS or IB
  • Documentation of listed vs unlisted events
  • Reference safety document used
  • Justification for expectedness classification

Clinical Evaluation Evidence

  • Review of patient history and risk factors
  • Assessment of alternative causes
  • Evaluation of temporal relationship
  • Clinical coherence of case narrative

Signal Identification and Escalation

  • Identification of potential safety signals
  • Escalation of unusual or unexpected events
  • Documentation of signal consideration
  • Communication to safety or governance teams

Regulatory Basis (Primary Sources)

  • GVP Module VI – requirements for medical evaluation of ICSRs
  • ICH E2A – clinical safety data assessment expectations
  • ICH E2D – post-marketing case assessment requirements
  • MHRA GPvP guidance – clinical evaluation of safety data
  • FDA pharmacovigilance guidance – medical review expectations

Typical Inspection Questions (What Inspectors Ask)

  • How do you perform medical review of ICSRs?
  • How is causality determined?
  • How do you assess expectedness?
  • Show me the medical review for this case.
  • How do you identify safety signals from cases?

Failure patterns

Medical review is superficial or not documented.

Causality assessments lack rationale.

Expectedness is incorrectly classified.

Clinical inconsistencies are not identified.

Potential safety signals are not escalated.

What good looks like

  • Structured and consistent medical review process.
  • Clear documentation of causality and expectedness.
  • Clinical reasoning supported by patient and product context.
  • Accurate identification of confounding factors.
  • Appropriate escalation of potential safety concerns.

Operationalisation

  • Implement structured medical review workflows.
  • Use medical review worksheets or templates.
  • Ensure qualified reviewers assess each case.
  • Document causality and expectedness clearly.
  • Train reviewers on consistent clinical evaluation.
  • Integrate medical review with signal detection processes.

FAQ

What is medical review in pharmacovigilance?

Medical review is the clinical evaluation of an ICSR to confirm causality, expectedness, and overall case interpretation.

What is causality assessment in pharmacovigilance?

Causality assessment is the process of determining whether a medicinal product is likely to have caused an adverse event, based on factors such as temporal relationship, clinical plausibility, dechallenge and rechallenge information, and alternative explanations.

How is causality assessed in ICSRs?

Causality is assessed based on temporal relationship, clinical plausibility, dechallenge/rechallenge information, and alternative causes.

What is expectedness in pharmacovigilance?

Expectedness refers to whether an adverse event is listed in the product’s reference safety information such as the CCDS or IB.

Do inspectors review medical assessments?

Yes. Inspectors frequently review medical assessments to confirm that clinical reasoning is documented and justified.

How are safety signals identified from ICSRs?

Signals may be identified when unusual, unexpected, or repeated events are observed and escalated for further evaluation.

What are common medical review failures?

Common failures include lack of documented rationale, incorrect expectedness classification, and failure to identify confounding factors.
