What Is an Individual Case Safety Report (ICSR)?

A Key Component of Pharmacovigilance

Pharmacovigilance plays a vital role in overseeing the safety of medicinal products during the lifecycle of the products. The Individual Case Safety Report (ICSR) is considered to be one of the most significant tools that are employed to monitor and analyze adverse events. The ICSRs allow the regulatory bodies and pharmaceutical firms to recognize the possible safety hazards and take the necessary measures in time to safeguard patient health.

A specific case safety report (ICSR) refers to a report that contains the details of an individual patient with a suspected adverse event that occurs because of the use of a medicinal product. ICSRs can be either of healthcare professionals, patients, clinical trials, scientific literature or post-marketing surveillance.

All the ICSRs have organized contents enabling regulators to determine causality, severity, and foreseeability of the covered accident.

When Are ICSRs Required?

ICSRs are required to be provided to the regulatory bodies in instances when:
  • There is a high probability of major adverse events.
  • The negative response is a surprise.
  • This happens either in clinical trials or post-marketing.

Different jurisdictions have different submission schedules, e.g. 15 calendar days in most regulatory systems, including the EU and FDA systems.

Key Components of an ICSR

Patient Information
Simple demographic information, including age, gender, and medical history.
Adverse Event Details
  • Explanation of the reaction, severity, outcome, and the time of onset.
  • The suspected product information is determined by the product data found on the design and packaging.
  • Name of drug, dose, dates of treatment, and indication.
Causality Assessment and Reporter.
Data about the reporter and assessment of the correlation between the drug and the event.
Importance of ICSRs in Drug Safety
ICSRs form the foundation of signal detection and ongoing benefit–risk assessment. Accurate reporting helps identify new safety concerns and supports regulatory decision-making.
