Human factors can be a tricky topic that creates confusion, especially when it comes to medical devices. On today’s episode, we have Mike Drues, president of Vascular Sciences, to help us dive deeper into nuances of human factors.

The root cause for human factors related to medical devices is the watershed moment with infusion pumps that happened about 10 years ago.

Did you know that infusion pumps are one of the most often recalled medical devices for safety reasons? This has led to rigorous testing for all medical devices. But despite lessons learned, infusion pumps are still being recalled today.

Quotes by Mike:

“All companies should have a responsibility…to do human factor or usability or ergonomic testing on their devices. There’s no question about it.”

“I would like to think that we as an industry have really learned and improved. But, unfortunately, there’s still an awful lot of learning and improving that needs to be done.”

“Those lines are becoming more and more blurry all the time because…we have more and more devices both on the market as well as under development where the user and the patient is, in fact, one of the same.”

“What good is doing a test, whether it is a human factors study or anything else, if it’s not realistic of the real world?”
