Pharmacovigilance Narrative Writing Practice: ICSR Examples for Beginners

Practicing Narrative Writing in Pharmacovigilance (PV): Learner Notes with Simulated ICSR Examples

Introduction

While learning pharmacovigilance, I realized that understanding the guidelines and standard structure of narrative writing alone is not enough to feel confident in real-world PV case processing. Narrative writing started to make more sense to me only when I began practicing it repeatedly using realistic scenarios.

As part of my learning process, I practiced narrative writing using simulated (dummy) Individual Case Safety Report (ICSR) examples. These cases do not involve real patients or real safety data, but they closely resemble the types of cases handled during routine pharmacovigilance work.

I compiled all my practice cases in this post so that I can revisit, revise, and deepen my understanding of narrative writing over time. It would also be helpful for other PV learners who want to understand narrative writing through practical examples collected in one place.

 Pharmacovigilance Narrative Writing: Guidelines and Standard Structure 

What I Focused on While Practicing

While working through these examples, I mainly focused on:

• Identifying key case elements
• Maintaining a clear chronological flow
• Using neutral, factual, and regulatory-appropriate language
• Applying seriousness criteria correctly
• Avoiding assumptions or personal medical judgment
• Clearly documenting missing information as not reported

Narrative Structure I Followed

For every case, I tried to follow a consistent structure:

• Patient information
• Suspect drug and indication
• Adverse event description and onset
• Seriousness assessment
• Action taken and treatment
• Outcome

Keeping the same structure for each case helped me write more clearly and consistently.

Tense Used in Narrative Writing

1. During practice, I learned that narratives are written mainly in the past tense, as they describe events that already occurred.
2. Present tense is used only to describe the current status at the time of reporting, such as “the patient is recovering” or “the outcome is unknown.”

Simulated Narrative Writing Practice Cases

Key Takeaways

1. Narrative writing becomes clearer through repeated practice with realistic case scenarios.
2. Seriousness classification depends on outcomes such as hospitalization, life-threatening events, disability, or fatality.
3. Clear chronology improves readability and regulatory compliance.
4. Missing information should always be documented as “not reported.”
5. Neutral and factual language is essential, especially in serious and fatal cases.
6. Even non-serious cases require complete and structured narratives.
