Introduction
This document will guide users through the changes being made to reporting manufacturer incident reports (MIR) and field safety corrective action reports (FSCAs) to the MHRA following implementation of the Medical Devices (Post-market Surveillance Requirements) (Amendment) (Great Britain) Regulations 2024. 听
Section 1: Background
Serious incidents involving medical devices which occur in the UK and meet vigilance reporting criteria must be reported to the MHRA by the manufacturer or their UK Responsible Person via the Manufacturer鈥檚 Online Reporting Environment (MORE) portal. FSCAs affecting devices in the UK and trends in incidents should also be reported using this portal.
The data standards used to report are updated for reports relating to Great Britain (GB) due to the new set of regulations - The Medical Devices (Post-market Surveillance Requirements) (Amendment) (Great Britain) Regulations 2024 which amends the UK Medical Devices Regulations (UK MDR) 2002 by inserting a new Part 4A on post-market surveillance (PMS) requirements for medical devices, including in vitro diagnostic (IVD) devices and active implantable medical devices which apply within GB.
Further information on the post-market surveillance requirements can be found here: The Medical Devices (Post-market Surveillance Requirements) (Amendment) (Great Britain) Regulations 2024: guidance on implementation - 天美影院.
MORE services
You should continue to refer to the following supporting documents for use of MORE:
These documents will be updated in line with the new requirements.
In the MORE portal, registered users will be able to make submissions via manual data entry via the web forms within MORE portal, XML report upload, or via Application Programming Interfaces (API). The MORE web forms that are available include:
- Manufacturer Incident Report (MIR)
- Field Safety Corrective Actions (FSCAs)
- Trend Reports
- Periodic Summary Reports (PSRs)
- Serious Adverse Events (SAEs)
This document outlines changes to MIR and FSCA schemas. Trend reports, PSRs and SAEs have no changes.
Section 2: Summary of changes to MIR and FSCA
The below table shows a high level summary of the changes made from MIR 7.2.1 and FSCA 2.8 to support the new GB schemas.

To aid comparison to the existing MIR 7.2.1 schema, the MIR help text has been annotated with the changes to the fields. Any changes between EU MIR 7.2.1 and the GB schema are on the tab named 鈥�7.2 Help text GB鈥�. Please note that some elements within the xsd will be changed which are not part of the existing help text. Each change to the MIR xsd is provided below.

Implementation Steps
Please use the resources available [to be released soon] to update your systems and processes in line with the GB xsd schemas to ensure compliance with the PMS requirements. Submissions under PMS legislation for GB should be reported using the GB schemas, and xml submissions should include the correct schema within the xml header. Reports for Northern Ireland can continue to be submitted in line with EU requirements.
If you need to provide a new submission to a previously submitted MIR or FSCA, you should update the schema in line with the new requirements, and it will be linked on the MHRA system as usual. Explicitly, it is acceptable to have a first submission using EU schema, and a second submission using GB schema.
During the transition period you can submit using the EU schema or new GB schemas. After the end of the transition period, you must use the GB schema to fulfil your reporting requirements under the PMS legislation.
Resources
Additional documentation to support the implementation of the GB schema will be provided within the resources tile and will include an overview of the changes made, an updated MORE submissions guidance document, a bridging document for MIR helptext, updated xsds and example xmls.
You will also be able to access these resources within MORE via the 鈥楻esources鈥� tile on the dashboard or left-hand side burger menu.
