Guidance on Field Safety Notices for Medical Device Manufacturers in the UK

1. Purpose and scope of FSN guidance

Field Safety Notices (FSNs) are communications issued by medical device manufacturers to inform users, customers, and regulators about corrective actions needed to address identified safety issues with a device, such as defects or risks that could compromise patient safety. The UK’s Medicines and Healthcare products Regulatory Agency (MHRA) provides specific guidance for manufacturers on how to produce and distribute effective FSNs.

2. When an FSN is required

Manufacturers must prepare and issue an FSN when a Field Safety Corrective Action (FSCA) is necessary to reduce or eliminate a risk associated with a medical device that is already on the market. This may include product recalls, modifications, or other actions to protect patients and users. FSNs ensure that those affected by a safety concern are informed promptly and clearly about what actions they need to take. Source: Medical devices: post-market surveillance ([GOV.UK][2])

3. Key elements of an effective FSN

An effective FSN should clearly state:

• The identity of the medical device affected
• The nature of the safety issue or defect
• The actions required by the user to mitigate risk
• Contact details for the manufacturer for further support

Clarity and completeness help healthcare professionals and customers understand the issue and comply with the instructions without delay. Guidance from MHRA emphasizes these principles to enhance communication effectiveness. Source: Lexology on FSNs requirements ([Lexology][3])

4. Distribution and traceability

Manufacturers should ensure that FSNs are distributed to all relevant recipients, including users, healthcare facilities, distributors, and importers. Accurate traceability is essential to confirm that the notice has reached the intended audience and that corrective actions can be tracked. MHRA guidance underscores the importance of maintaining records of distribution and responses where applicable. Source: Field safety notices guidance summaries ([Steptoe][4])

5. Relationship with FSCA reporting

FSNs usually accompany a Field Safety Corrective Action (FSCA) report submitted to the MHRA when a safety issue meets regulatory reporting thresholds. The MHRA monitors FSN compliance and may publish notices for information, but the responsibility for issuing and executing FSNs rests with the manufacturer.

6. Post-market vigilance integration

FSNs form part of the broader post-market surveillance and vigilance system, which includes reporting adverse incidents, trends, and corrective actions. Manufacturers should integrate FSN preparation into their overall vigilance processes to ensure timely, accurate communication of safety information.

7. Best practices for manufacturers

Best practice recommendations from MHRA guidance include:

• Using clear, unambiguous language in FSNs
• Updating FSNs if additional information becomes available
• Conducting follow-up to confirm that recipients have received and understood the notice
• Keeping documentation of FSN issuance for inspection

These practices help ensure that safety communications are effective and regulatory expectations are met. Source: Effective Field Safety Notices guidance information ([GOV.UK][1])
