Overview
EN ISO 27953-1:2011 (ISO/HL7 27953-1:2011) defines an international framework for adverse event reporting focused on Individual Case Safety Reports (ICSRs) in pharmacovigilance. The standard specifies a common messaging format for exchanging ICSRs that document adverse drug reactions (ADRs), adverse events (AEs), product problems and consumer complaints associated with one or more products. The messaging approach is based on the HL7 Reference Information Model (RIM) and is designed to be extensible and constrainable to accommodate diverse reporting scenarios across organizations and regions.
Key topics and technical requirements
- Common messaging format for transmission of ICSRs to support consistent data exchange between health care providers, regulators and pharmacovigilance systems.
- HL7 RIM–based model: ICSR message constructs are derived from the HL7 Reference Information Model to promote semantic interoperability.
- Extensibility and constraints: Message structures can be extended or constrained to meet specific use cases (regional regulations, organizational workflows).
- Harmonization intent: Designed to align over time with other HL7 public health and patient safety reporting standards to ensure consistent constructs and vocabulary across reporting domains.
- Core data elements: Identifies a set of consistent data elements applicable across many use cases (patient, suspect product, event, reporter, outcome); note that exact reporting requirements may vary by authority or organization.
- Scope of reports: Covers ADRs, AEs, product problems and consumer complaints related to product administration/use.
Practical applications
- Exchange of ICSR data between marketing authorization holders (MAHs), national competent authorities and international pharmacovigilance centers.
- Integration of adverse event reporting into electronic health records (EHRs), safety databases and signal-detection systems.
- Standardizing submission pipelines for regulatory reporting and for aggregating safety data from multiple sources.
- Enabling cross-border and multi-vendor interoperability for pharmacovigilance workflows.
- Supporting automated processing and downstream analytics (case triage, signal management, regulatory compliance).
Who should use this standard
- National regulatory authorities and pharmacovigilance centres
- Pharmaceutical companies and MAHs responsible for ICSR submission
- Healthcare IT vendors, EHR integrators and safety database providers
- Software developers building reporting interfaces and message converters
- Public health agencies and organizations involved in patient safety reporting
Related standards and harmonization
- Based on and intended to be harmonized with HL7 public health and patient safety reporting standards and other ISO/HL7 initiatives.
