Information about Which Medical Device

What is Which Medical Device?

Which Medical Device
is a review and information site about medical devices developed by clinicians for clinicians. It was launched with the aim of sharing information about medical devices to help us make better decisions and use devices well. We believe clinicians want to know what devices are really like from colleagues and the evidence.  

In this short video Dr Phil Haslam and Craig Gerrand discuss their motivation for established and their goals for the website



Which Medical Device is based on the highly successful ‘Which Interventional Device’ website for interventional radiologists, launched in 2007 by Phil Haslam. The site was well received and had over 1700 members in 2010: feedback from the community was almost universally positive. It was clear that other areas of clinical practice would also benefit and so Which Medical Device was launched in 2010 and has now in excess of 7,200 clinician members. The site receives over 17,000 visits per month.

How can I contribute?

We welcome contributions from the medical device community, including clinicians, device developers, manufacturers and distributors.

How reliable is the information on Which Medical Device?

We do our best to make sure information on Which Medical Device is up to date and regularly review content, but see our disclaimer. Please let us know if you see something incorrect or out of date.

How is Which Medical Device funded?

To pay the bills, we charge manufacturers and distributors for adding supporting promotional materials. Manufacturers benefit by presenting product literature, images and videos to interested clinicians and as members, can respond to comments made by users. We believe that open dialogue and collaboration between manufacturers and clinicians is in everyone’s best interests. We also provide manufacturers with aggregated statistics about their device pages, which include items such as the number of users that have looked at their devices. These data do not include user-identifiable information, which we would not pass to anyone without consent. Devices are chosen for listing independent of whether the manufacturer sponsors a product. For more information about how Which Medical Device can support industry partners look here.

How independent are we?

We want the information on Which Medical Device to be as useful as possible.  It should always be clear whether you are looking at marketing material or independent opinion. We therefore ask that reviewers declare conflicts of interest when submitting reviews, but we appreciate that the relationships that clinicians have with companies and medical devices are many and varied. If you are aware of an undeclared conflict of interest in a review or comment please let us know. We have zero tolerance for biased or fake reviews.
Our relationship with manufacturers is similar to that of a medical journal. We believe that placing sponsored content adjacent to independent reviews is a legitimate source of income, and that users will be able to tell what content has been paid for by the manufacturer. The posting of product information by manufacturers does not depend on favourable reviews. We expect manufacturers to comply with the ethical standards given in Eucomed guidance (
