IEC TR 62366-2:2016, Medical devices – Part 2: Guidance on the application of usability engineering to medical. The evaluation plan should have a clear objective and the method of evaluation. IEC 62366-1:2015 standard asks the manufacturers to maintain a Usability Engineering File, containing a list of documents required to be in compliance with the standard. Usability Engineering or Human Factors Engineering is the application of knowledge about human behavior, abilities, limitations, and other characteristics to the design of MEDICAL DEVICES (including software), systems and TASKS to achieve adequate USABILITY. The standard describes a Usability Engineering Process with 9 stages: 1. It is provided by several institutions and their regulations, the most frequent ones are the FDA, the MDR and the standard IEC 62366-1. The risk management performed, identification of the hazards and hazardous situation should be addressed with the appropriate design / risk controls to make sure the necessary action is taken to avoid the known or foreseeable hazards and hazardous situations. Although there might be different regulatory requirements for usability and medical devices, depending on the country, there is one overlap: the IEC 62366 Medical devices – application of usability engineering to medical devices. Created by > Usability Engineering. The records and documents arising from the usability Engineering process could be completely separate from the design & development documents and the risk management documents or could be a part of the entire design & development documents. In the MDR, there are specific requirements for the aspect of usability, most of them are part of the General Safety and Performance Requirements, stating mainly that a manufacturer should eliminate or reduce risks that are related to error use. In contrast to the MDR, the FDA is quite specific about the regulations on usability and addresses this topic since decades.

All the medical devices that were manufactured prior to the publication of the standard, IEC 62366-1:2015 can also comply to this standard by assessing the medical device considering the Use specifications and User interface specifications, Post-market data, applying risk controls if necessary and by maintaining an UEF having the document evidences of Use & User interface specifications, PMS data assessment, risk management and verification of the risk controls. As well as with other aspects of medical devices, there is a regulatory framework, too, when it comes to usability. Also, devices for use by lay persons need to be designed and manufactured in such a way as to ensure safety when using them properly as well as to reduce the risk of error by handling the device. Companies must be familiar with these requirements if they want to prove to FDA or other regulatory bodies that they have a usability program in place. Gaining approval for medical devices is complex and quite often also confusing. That is why institutions became more and more aware of the fact, that usability engineering should be incorporated into regulations and become a substantial part of requirements to medical devices. Although, it is not to underestimate what impact usability has on healthcare. We bring clarity…, Clinical affairs of medical devices requires numerous evidences and evaluations. That is why a thoroughly implemented usability process is essential to every manufacturer of medical devices. This is the application of information about human behavior, capabilities, shortcomings, and other features to the design of medical devices like software, systems, tasks to achieve adequate usability. In addition… Thus, the UE process according to the IEC 62366 standards family is important to ensure usability of all medical devices. This part of IEC 62366 specifies a PROCESS for a MANUFACTURER to analyse, specify, develop and evaluate the USABILITY of a MEDICAL DEVICE as it relates to SAFETY. If you agree, please click ok.
