From the ventilator to the pulse oximeter to the surgical robot, medical care is mediated by sophisticated devices. It takes time to learn to use these devices safely. They require upkeep from skilled technicians. If something goes wrong, the consequences may be devastating for the patient. So how do Australian hospitals ensure that clinicians know how to use devices safely, when to update them, how they should be serviced and so on? Unbeknownst to many patients and the public, these services, and more, are performed by medical device representatives or MDRs. MDRs are employed by the companies that make equipment and devices to ensure that their products are used as safely and effectively as possible. But this is not the only role that MDRs have. They are also sales people, tasked by the companies they work for to sell products directly to the clinicians who use them. This dual role of support and sales raises many ethical questions about the range of activities of MDRs and their impact on patient care. Join host Distinguished Professor Wendy Rogers and guest Dr Brette Blakely as they investigate the ethical complexities that arise from the multiple roles played by medical device representatives in Australian Hospitals. This podcast features a paper in progress. The paper is one of the research outputs of the ARC Discovery project (DP200100883): Support or sales? Medical device representatives in Australian hospitals, led by Dr Jane Johnson at Macquarie University, and on which Wendy Rogers is also a CI.
