What are ICSR narratives?
In the realm of pharmacovigilance and patient safety, ICSR narratives play a crucial role by providing a concise overview of the entire case.
This includes a brief summary of the patient’s medical history, reported adverse events, medications administered, their outcomes, and pertinent information about the reporter.
Purpose
The essence of the narrative lies in comprehending the case through a concise summary of events and their causal link to the drug. It serves to define the event and its relationship with the drug by highlighting relevant points.
Why ICSR Narratives Matter?
Act as brief summary
ICSR case narratives serve as simplified case summaries, facilitating easy review and inclusion of comments. Following ICH guidelines, the narrative is mandated in the structure of ICSR, defined as a case summary. Additionally, in accordance with ICH E2B (R3) data elements, the narrative holds mandatory status within its structure.
I strongly encourage you to explore another blog that thoroughly examines the diverse range of E2B formats.
Narrative transcends mere writing; it is an artistic expression. While individual writing styles vary significantly, in the realm of ICSR (Individual Case Safety Reports), a standardized format is essential.
Inclusion of additional info
Narratives helps easy comprehension of cases by offering supplementary text data elements. Text data elements are intended to provide additional information that cannot be provided in structured format using reference standard terminology. For example some patient characteristics.
Inclusion of Repetitive Details
Certain information warrants repetition, but encoding it within structured fields proves challenging. In such cases, narratives come to the rescue. While generally avoiding redundancy is advised, this approach is recommended when necessary.
Managing Parental and Fetal Cases
Narratives comes to handy and greatly helpful in complicated pregnancy cases. For example: In parent-child/foetus report, If a father is the source of the suspect drug(s) then the additional information on drug is provided. The case narrative should describe the entire case, including the father’s information.
Uncertainties with suspected drug(s)
In general, it is advisable to adopt a cautious approach, and when in doubt, the product should be treated as a suspected drug. Any crucial or contentious matters related to this judgement can be succinctly addressed in a narrative.

Capturing adverse event
The overall adverse event experience in the study should describe in a brief narrative, supported by the following more detailed tabulations and analyses.
Managing fatal case
There should be brief narratives describing each death, each other serious adverse event, and those of the other significant adverse events that judged to be of special interest because of clinical importance.
Clinical abnormalities
Discuss clinically significant changes as defined by the applicant. Provide a narrative for each patient experiencing a laboratory abnormality classified as a serious adverse event, mention only on those significantly related to the event.
Tracking
The narrative assumes a significant role in effortlessly tracking cases, particularly in scenarios involving a substantial number of Follow-Up (FU) reports. Its utility becomes particularly evident in these instances.
Important components of ICSR narrative
Fundamentals
According to ICH E3 guidelines, i mention below here based on the information available in it:
- Clinical course
- Therapeutic measures
- Outcome
- Action taken
- Any crucial findings (if applicable): For example: Autopsy, laboratory
- Reporter’s comment
- Sender’s comment
In addition, the following information should be included:
- Patient identifier
- Age and sex of patient; general clinical condition of patient, if appropriate Disease treated (if the same for all patients this not required) with duration (of current episode) of illness
- Relevant concomitant/previous illnesses with details of occurrence/ duration
- Relevant concomitant/previous medication with details of dosage
- Test drug/investigational product administered, drug dose, if this varied among patients, and length of time administered
Optional Yet Repeated When Required
For example:
- Sender’s Diagnosis
- For example: MedDRA Version and MedDRA code for Sender’s Diagnosis / Syndrome and / or Reclassification of Reaction / Even
- Reporter’s comment as necessary
- Reporter’s comment language
Closing thoughts
As you’ve journeyed through this blog, the significance of narrative in ICSR has likely taken shape in your understanding. We’ve delved into the necessities and explored the optional aspects, unraveling the pivotal role narratives play in comprehensive reporting.
Remember, beyond the essentials lie opportunities for nuanced detailing, ensuring a richer context for every case. In the dynamic landscape of pharmacovigilance, mastering the art of narrative construction not only meets requirements but elevates the quality of safety reporting. Keep these insights in mind as you navigate the evolving terrain of ICSR documentation.
