A pre-dispatch inspection (PDI) for medical devices is a quality control process conducted before products are shipped from the manufacturing facility to ensure that they meet the specified requirements, conform to quality standards, and are in compliance with regulatory expectations. The primary goal of a pre-dispatch inspection is to verify that the medical devices are of the highest quality and that they will perform as intended once they reach the end-user. Here are key considerations for implementing a pre-dispatch inspection for medical devices:

Inspection Plan: Develop a comprehensive inspection plan that outlines the criteria, specifications, and acceptance criteria for the medical devices. This plan should be based on product specifications, regulatory requirements, and quality standards.

Sampling Strategy: Define a sampling strategy to ensure representative units are selected for inspection. The sampling plan should consider factors such as batch size, manufacturing variability, and the criticality of specific product characteristics.

Inspection Criteria: Clearly define the inspection criteria for the medical devices, covering aspects such as dimensions, functionality, labeling, packaging, and any other critical attributes. Ensure that the criteria align with product specifications and regulatory requirements.

Regulatory Compliance: Verify that the medical devices are in compliance with relevant regulatory requirements. This includes adherence to standards such as ISO 13485 for quality management systems for medical devices and specific product standards applicable to the devices.

Documentation Review: Review and verify all relevant documentation, including production records, quality control records, and certificates of analysis. Ensure that the documentation is complete, accurate, and meets regulatory and quality system requirements.

Functional Testing: Perform functional testing on a representative sample of the medical devices to ensure that they operate as intended. This may involve testing specific features, performance characteristics, or critical functions relevant to the device's intended use.

Packaging Inspection: Inspect the packaging of the medical devices to ensure that it meets the specified requirements. Verify that labeling is accurate, legible, and in compliance with regulatory requirements. Check for any damage or discrepancies in the packaging.

Labeling Compliance: Ensure that the labeling on the medical devices is accurate and in compliance with regulatory requirements. This includes verifying the correctness of product identifiers, instructions for use, and any required symbols or warnings.

Visual Inspection: Conduct a visual inspection of the medical devices to identify any cosmetic defects, physical damage, or other issues that may impact the product's appearance or usability.

Traceability and Serialization: Confirm that the medical devices are traceable through the production and distribution process. For serialized products, verify that the serialization information is accurate and corresponds to the associated records.

Documentation of Inspection Results: Document the results of the pre-dispatch inspection, including any deviations or non-conformities identified during the process. Maintain clear and detailed records for future reference and analysis.

Release Authorization: Only authorize the release of medical devices for shipment after the pre-dispatch inspection confirms that the products meet all specified criteria and quality standards.

Continuous Improvement: Use insights gained from pre-dispatch inspections to identify opportunities for process improvement. Implement corrective and preventive actions to address any issues identified during the inspection process.
