After obtaining Class C medical device registration with Singapore's Health Sciences Authority (HSA), there are several important responsibilities and obligations that manufacturers and distributors must adhere to in order to maintain compliance with regulatory requirements and ensure continued market access. These responsibilities are mainly focused on post-market activities, surveillance, and ensuring the safety and effectiveness of the device in the long term.

Here’s what to pay attention to after obtaining Class C medical device registration with HSA:

1. Post-Market Surveillance (PMS)

• Monitor device performance: Regularly assess the device’s performance in real-world settings and gather data on its safety and effectiveness.
• Adverse event reporting: If any adverse events (e.g., device malfunctions, side effects, injuries) occur, you must report them to HSA in a timely manner as per the vigilance requirements.
• Field safety corrective actions (FSCA): If safety issues arise, you may need to take corrective actions such as issuing a product recall, providing warnings, or implementing changes to the device.
• Periodic safety updates: You may need to submit Periodic Safety Update Reports (PSURs) or similar documents, depending on the device type and risk level.

2. Renewal and Maintenance of Registration

• Registration validity: HSA registration is typically valid for 5 years for Class C devices. You must apply for renewal before the registration expires to ensure your device remains on the market.
• Renewal application: For the renewal, submit an updated application, including any new data or changes to the device (e.g., new clinical evidence, post-market surveillance results, manufacturing updates).
• Updating the device's information: If there are any changes to the device’s intended use, design, or manufacturing process, you must notify HSA and, if necessary, submit a new application or amendment.

3. Compliance with Good Manufacturing Practice (GMP)

• Ongoing compliance: Ensure that your device continues to meet Good Manufacturing Practices (GMP) throughout its lifecycle.
• Internal audits: Conduct regular audits of your QMS and manufacturing processes to ensure they continue to meet ISO 13485 or other relevant standards.
• Supplier monitoring: Monitor suppliers and subcontractors to ensure they maintain quality standards for raw materials and components.

4. Reporting of Adverse Events (Vigilance)

• Mandatory reporting: If the device causes serious adverse events, harm, or is found to be defective, report these issues to HSA within specific time frames. This is an essential part of post-market vigilance.
• Risk assessment and corrective actions: If new risks are identified through adverse event reporting or post-market surveillance, you may need to take corrective actions and submit reports to HSA.

5. Labeling and Packaging Compliance

• Ensure labeling remains accurate: After obtaining registration, you must ensure that the device’s labeling continues to meet HSA’s requirements. Any updates to labeling (such as warnings or changes in usage instructions) must be approved by HSA.
• Updates to packaging: Ensure that the packaging remains compliant with regulations, particularly if any changes are made to how the device is sterilized, stored, or transported.

6. Changes to the Device

• Notifying HSA of changes: If any changes occur that affect the device’s safety, effectiveness, or intended use, such as changes in the design, materials, or manufacturing processes, you must notify HSA and, in some cases, submit a new application or get approval for modifications.
• Significant changes may include:
  • Alterations to the device's indications for use.
  • Changes in the clinical data or risk management practices.
  • Modifications in the manufacturing facility.
• Software updates: For devices that include software, any major software updates must be assessed for impact on device safety and performance, and reported to HSA if necessary.

7. Post-Market Clinical Follow-up (PMCF)

• Clinical data collection: If applicable, continue gathering and analyzing clinical data after the device has been marketed to ensure ongoing safety and performance.
• Adjustments to the device: Based on findings from post-market studies or feedback, you may need to make adjustments to the device.

8. Marketing and Distribution Requirements

• Distributor compliance: Ensure that all distributors and authorized representatives maintain compliance with HSA requirements. This includes making sure the devices are stored, transported, and distributed under appropriate conditions to ensure safety.
• Device recalls: If a recall is necessary, it is your responsibility to ensure the process is carried out effectively, and you may need to communicate with HSA, healthcare providers, and customers.

9. Export and International Compliance

• If you plan to market your device in other countries, ensure that it complies with the regulatory requirements of those markets. For example, you may need to submit documents showing your device is CE marked or FDA-approved to facilitate entry into international markets.

10. Quality Management System (QMS) and Audit Compliance

• Internal audits: Conduct regular internal audits of your QMS, ensuring ongoing compliance with ISO 13485 and other relevant standards. If necessary, engage in external audits.
• Corrective and preventive actions (CAPA): Implement a robust CAPA system to address any non-conformities identified during audits, inspections, or through post-market surveillance.

11. Continuous Improvement and Documentation Updates

• Document updates: Regularly review and update your technical documentation, clinical evaluation reports, and risk management plans to reflect any new findings, changes in standards, or clinical data.
• Continual improvement: Ensure that you have a process in place to improve the design, manufacturing, and safety aspects of the device based on feedback, risk assessments, and post-market data.

Conclusion:

Once your Class C medical device is registered with HSA, staying compliant with ongoing regulatory requirements is critical. Maintaining a proactive post-market surveillance system, handling adverse events, keeping your device documentation up to date, and ensuring continuous quality are key elements in managing the lifecycle of your device. Additionally, any modifications to the device, manufacturing processes, or labeling must be communicated to HSA to maintain registration and ensure ongoing patient safety and product effectiveness.
