Adverse event case processing (ICSR workflow, MedDRA coding, WHO-ART taxonomy)
The standardized, regulatory-driven process of receiving, documenting, evaluating, and reporting individual case safety reports (ICSRs) of adverse events, using MedDRA for precise medical terminology coding and WHO-ART as a historical reference taxonomy for classification.
This skill is non-negotiable for pharmaceutical and biotech companies to ensure regulatory compliance with global health authorities (FDA, EMA, PMDA), directly preventing fines, clinical holds, and product recalls. It is the foundational mechanism for drug safety signal detection, directly impacting patient risk management and a product's risk-benefit profile.

How to Learn Adverse event case processing (ICSR workflow, MedDRA coding, WHO-ART taxonomy)
1. Master ICH E2A/E2B(R3) guidelines and the core structure of an ICSR (Patient, Reaction, Test, Drug, Narrative). 2. Achieve basic proficiency in MedDRA: understand its five-level hierarchy (SOC, HLGT, HLT, PT, LLT) and practice coding terms from simple source documents. 3. Understand the WHO-ART historical context and its 4-level system (System-Organ Class, High-Level Term, Preferred Term, Included Term).
1. Process end-to-end ICSRs using a safety database (e.g., Argus, ArisGlobal), focusing on data entry, case assessment (seriousness, causality), and narrative writing. 2. Handle complex coding scenarios in MedDRA: multi-axial searching, selecting between similar PTs, and applying conventions (e.g., SMQs). 3. Avoid common mistakes: under-coding (using a too-general term), over-coding (using an overly specific term without support), and inconsistent narrative structure.
1. Architect and optimize ICSR workflow SOPs, defining triage timelines, quality control (QC) checks, and medical review escalation paths. 2. Lead MedDRA governance: establish internal coding conventions, train coders, and liaise with the MedDRA Maintenance and Support Services Organization (MSSO). 3. Strategically align case processing activities with signal detection and risk management plans, using aggregated case data to inform safety strategy.
Practice Projects
Beginner
Case Study/Exercise
ICSR Triage and Basic MedDRA Coding
Scenario
You receive a spontaneous report from a physician: 'Patient developed severe chest pain and elevated liver enzymes after taking Study Drug X for 2 weeks.' The report lacks some details.
How to Execute
1. Use an ICSR checklist to identify missing information (e.g., patient demographics, exact dates, dechallenge/rechallenge). 2. Draft a follow-up query letter to the reporter. 3. Using the MedDRA browser, code the reported events 'chest pain' and 'elevated liver enzymes' to the most precise Preferred Term (PT) level (e.g., Chest pain, Transaminases increased). Justify your PT selection.
Intermediate
Case Study/Exercise
End-to-Case Processing with Medical Assessment
Scenario
A 65-year-old male patient in a clinical trial experienced a fatal myocardial infarction (MI) 3 days after an infusion. The investigator deems the event 'possibly related.' You must process this serious, fatal, related ICSR for expedited regulatory reporting.
How to Execute
1. Enter all data into a safety database template, correctly flagging seriousness criteria (Death, SAE) and company causality. 2. Code all events (MI, fatal outcome) using MedDRA, applying any relevant SMQs (e.g., 'Acute myocardial infarction'). 3. Write a concise, factual narrative including key elements: patient history, suspect drug details (dose, route, dates), event timeline, autopsy results (if any), and the investigator's assessment. 4. Calculate the regulatory reporting clock (e.g., 7-day for fatal, 15-day for other serious) and generate the ICSR for QC.

Case Study/Exercise
ICSR Workflow Optimization & Signal Triage
Scenario
Your safety database shows a cluster of 5 ICSRs over 3 months for 'pancreatitis' in patients taking Drug Y. All were serious but non-fatal. Your team's case processing is backlogged, and a regulatory authority requests a line listing.
How to Execute
1. Analyze the backlog root cause: is it staffing, query response time, or medical review bottleneck? Propose and implement a targeted solution (e.g., a dedicated 'high-volume' queue). 2. Lead a signal triage meeting with a safety physician. Prepare a pre-meeting analysis: aggregate the 5 cases, present demographics, latency, dechallenge/rechallenge data, and background rate comparison. 3. Based on triage, draft an assessment for the periodic safety report (PSUR) and determine if the signal requires further action (e.g., label update, a formal signal evaluation). 4. Create a concise summary report for the regulatory query, demonstrating control over both the operational backlog and the safety data.
Enterprise software platforms for ICSR data entry, workflow management, medical coding, regulatory report generation, and signal detection. Proficiency in at least one is mandatory for industry roles.
Medical Terminology & Coding Systems
MedDRA (Medical Dictionary for Regulatory Activities)WHO-ART (WHO Adverse Reactions Terminology)ICH E2B(R3) (Individual Case Safety Report)
MedDRA is the current global standard for coding. WHO-ART is legacy/historical knowledge. E2B(R3) defines the technical (XML) format for electronic submission of ICSRs to regulators (e.g., FDA's FAERS, EMA's EudraVigilance).
The guiding principles and legally binding requirements for case processing. GVP modules (especially Module VI) provide detailed operational standards. Internal SOPs are the specific, company-level implementation of these frameworks.
Interview Questions
Answer Strategy
The interviewer is testing hands-on MedDRA proficiency and problem-solving. Demonstrate a systematic approach. Sample Answer: 'I would start by searching for the verbatim term 'heart racing' in MedDRA. If no exact match exists, I would use synonyms or more formal medical terminology-here, I'd search for 'palpitations.' I would then review the PT list under the SOC 'Cardiac disorders,' comparing candidate PTs like 'Palpitations' versus 'Tachycardia.' Since the report lacks ECG confirmation of a rapid heart rate, 'Palpitations' is the more appropriate and specific PT for the subject's reported sensation. I would document this rationale in my coding notes.'
Answer Strategy
This tests signal detection awareness and initiative. Use the STAR method. Sample Answer: 'While reviewing the cumulative tabulation for a marketed product, I noted an unexpected cluster of 7 cases of severe rhabdomyolysis over two quarters, all with strong temporal association. I immediately flagged this to the Safety Director and prepared a line listing with key data points: patient age, concomitant statins, and time-to-onset. This formed the basis for a formal signal evaluation, which led to an independent literature review and a collaborative analysis with the R&D team. The outcome was a risk-management initiative that included an update to the product's risk management plan and enhanced monitoring instructions for healthcare professionals.'
