Design review is a valuable chance to stop and evaluate the situation when you are developing a medical device. Are the design requirements adequate? Is the design likely to meet these requirements? And, are there any problems that are yet to be identified?
In this video, you will find out more about how to best conduct a design review and what pitfalls to watch out for. If you want to know even more about design review and design control, check out the full online Introduction to Design Control course.
Design review – Is it worth the time?
Without a doubt! It is always better to fix an issue before the product has reached the market, rather than after. And design review should be an effective tool to find issues. But not only is it smart to do design reviews, it is also a regulatory requirement.
The term design review comes from the Quality System Regulation (QSR) and in the ISO 134 85 this is referred to as design and development review.
How do you perform a design review?
A design review should always be planned in advance. Thus, you can’t have ad hoc design reviews unless you create a plan before you have them.
There are several ways to perform a design review, but the most common way is to have a meeting with 5-10 people where you go over the design, requirements, and potential problems. Depending on the information available, the meeting can take anywhere from one to several hours.
Who should attend a design review?
Only relevant and competent individuals should attend the design review meeting. Representatives of all functions related to the design stage being reviewed should be present at the meeting, along with any necessary specialists.
To satisfy requirements for selling a medical device to US, at least one person taking part in the design review meeting is required to not have any direct responsibility for the design stage. This person is often called an independent person. If you work for a small company, you might have to bring in an external consulting resource who is sufficiently independent.
How many design reviews should you have?
Actually, there is no mention in the ISO 13 485 or QSR of how many design reviews you have to perform on your medical device, only that you are required to perform them when appropriate.
As such, the minimum requirement would be to perform a design review once, but a more reasonable amount would be a handful. However, if you have a very advanced or complicated device, you may need even more design reviews.
The importance of keeping design review records
It is required to maintain records of design review meetings. The simplest and typical way of doing so is to write minutes of meetings. They are records that should be kept according to your quality management system.
During a design review, you will likely find issues or even nonconformities that need to be addressed. You have to keep records of the necessary actions that you have identified.
The simplest way to do this is to add the actions as a task list in the minutes of the design review meeting. You can also record action items in a validated CAPA system or another similar database. The important thing is that you have a method to deal with the action items and maintain records of them.
A common mistake is that the project team forgets to follow up and properly close the open action items. Make sure to follow-up previous action items in every design review and even schedule separate follow-up meetings to make sure action items are closed in a timely manner.
Many organisations will also have a template for reviewing records, so if you have not performed a design review before, check if there is a template available.
On Medical Device HQ you can find a selection of free and paid-for templates, including a template for design review records.
