The complaint handling process for medical device manufacturers is of fundamental importance for multiple reasons. For sure, compliant process is directly linked with the safety of the devices on the field and, in terms of quality management system, linked with other processes such as risk management, vigilance reporting and active post-market surveillance activities.

We have been already talking of the vigilance reporting requirements according to the Quy định về thiết bị y tế của Châu Âu and according to FDA regulation (21 803 CFR). In this article, we want to give a more high level overview of the whole complaint process, from the reception of a complaint until its closure.

What is a Complaint

FDA provides a precise definition of complaint in the section 21 CFR 803 (b):

Any written, electronic, or oral thông tin việc này cáo buộc deficiencies related to the identity, quality, durability, reliability, safety, effectiveness, or performance of a device sau khi it is released for distribution.

As you can see, the key characteristic for a complaint is the presence of an allegation against a specific device. This is very important as it will be useful to determine if a specific communication received from the customer can be

Overview of Complaint Handling Process

The process for complaint handling can be summarised in the scheme below.

What type of information need be mentioned in a complaint received from a customer?

When a complaint is received from a customer, there is some specific information that need to be mentioned. Specifically

• The date of the event, which can be different from the event was reported to the manufacturer.
• The place when the event occurred.
• A description of the event, thus what exactly happened, or a description of the failure or potential failure, etc
• The medical device involved, including all the information needed to properly identify
• Any information related to the involvement of the patient in the specific event and, in case, the consequences of the event on patient, user or any other person involved. If there were consequences, it is often necessary to know whether there was medical intervention on the patient and/or in general the so-called patient outcome.

These are the minimal amount of information which are necessary to open the complaint and perform an initial evaluation of the complaint. Sometimes, this information is not available and it is necessary to contact the customer and collet all the necessary information.

Reportability Evaluation

We have been extensively talking about the criteria for repeatability for US and EU markets, thus we will not grow through those requirements again. Here it is just important to highlight that it is essential to collect all the necessary information to perform an adequate evaluation of the reportability of the event.

Technical Investigation

In another article we have been discussed about the techniques for root-cause analysis. In a context of complaint handling, the technical investigation can be quite different depending on the type of events and type of potential failures. However, in general, the technical investigation may contain the following items:

• the root-cause of the event, thus if it is related to a specific failure of the device, use error, or any other reason.
• review of the device history record for the device involved in the event, to check if any deviation potentially related to the specific event has been recorded in manufacturing documentation. Sometimes it is necessary to check as well device history record of devices manufactured in the same period of the one involved in the event (for example previous and subsequents lot or serial numbers).
• Complaint data history: it is often necessary to provide an overview of how many similar events have been received within a specific timeframe.
• If medical investigation had to be performed because the event imparted a consequence to a patient, the results shall be included in the investigation of the complaint. Often medical investigation is needed to evaluate the seriousness of the event (serious injury or not) and thus perform the appropriate reportability evaluation.

Risk Assessment Evaluation

It is important, once the root-cause of the event is determined, that a risk assessment is performed, to ensure the risk is still considered acceptable. It is important to remind it is not possible to have unacceptable risks for marketed medical device; once a risk became unacceptable, a field action or field safety notice shall be implemented.

Evaluation of the need to implement corrective action

Once the root-cause is determined, the evaluation of the necessity to implement corrective action shall be performed and documented. If no specific actions are taken, appropriate justification shall be documented.

Response to Customer

Response to customers with a summary of the complaint received and the results of the in investigation shall be provided under the following situations:

• the customer specifically requires a response
• a competent authority asks the manufacturer to provide a response
