Human factors related to healthcare reprocessing of medical devices is a valuable component of product development for all medical devices. If reprocessing steps are performed incorrectly, or not at all, it could result in serious harm to the next patient. In-use, or human factors testing, is a powerful method to ensure that users can appropriately follow and perform all of the reprocessing steps. This is an integral part of preparing the device for regulatory submission. Proper reprocessing of medical devices will decrease hospital acquired infections and increase patient safety.
