Applying Human Factors and Usability Engineering to Optimize Medical Device Design, Usability Engineering & die IEC 62366-1 für Medizinprodukte, Use Specification: the manufacturer should document the use specification of the medical device in the usability engineering file (UEF). Summative Evaluation: is performed to complete the development of the User Interface with the objective of demonstrating that the user interface can be safely used. In addition, the technical report IEC/TR 62366-2:2016 Medical devices - Part 2: Guidance on the application of usability engineering to medical devices was published to support the usability engineering process. It’s important to note that usability engineering shall be applied to all medical device, not exclusively active devices. Hazards and hazardous situations related to the use of the medical device shall be identified as part of the risk management process considering the use specifications and the user interface characteristics as identified in the early stages of the Usability Engineering process. Feedback from users and information about problems or errors need to be collected and evaluated, as well. There could be a single plan capturing the evaluations of all the user interface specifications or there could be multiple plans made at the each stage of the design and development of the medical device. At first sight, people are often confused by the term “usability engineering”, not knowing what to make out of it. IEC TR 62366-2:2016, Medical devices – Part 2: Guidance on the application of usability engineering to medical. But in fact, it is very essential to the safety and effectiveness of medical devices. In addition, usability engineering as part of mandatory risk managementshould have an overall positive effect on the quality of the product file and its evaluation. IEC 62366-1:2015 specifies a PROCESS for a MANUFACTURER to analyse, specify, develop and evaluate the USABILITY of a MEDICAL DEVICE as it relates to SAFETY. The evaluation plan should have a clear objective and the method of evaluation. As well as with other aspects of medical devices, there is a regulatory framework, too, when it comes to usability. With new documents, the structures of the UDI and basic UDI-DI are also clarified. normal use. If the medical devices are not used effectively or incorrect use of the user interface may result in Use errors. 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. But in fact, the concept of usability is a very important one when it comes to the safety and effectiveness of medical devices. Usability engineering, also called as human factors engineering, is nothing but the interaction between the user and the user interface of the medical devices. Having said that, IEC 62366-1:2015 is the standard recognized by the European Union, USFDA and the other major countries where the medical device regulations are stringent and difficult to comply. Residual risk evaluation: evaluate risk using criteria defined in the risk management plan, Risk arising from risk control measures: effects of risk control measures need to be reviewed, Completeness of risk control: ensure that risks from all identified hazardous situations have been considered. We are based in the UK and Sweden and focus … The formative evaluations can be module by module, developed stage wise. Usability engineering has been applied in the automotive or aerospace industries or others for more than half a century, but only recently in the medical industry. This guidance document is of course no standard, but it gives many lists with requirements and refers to the important regulations and the IEC 62366 (in the meantime superseded by IEC 62366-1). The following paragraph depicts a short summary of each step of the process: When usability is implemented and all requirements are fulfilled, there are certain procedures that can check the usability process. What we know about it …, Product development of medical devices is subject to its own rules. Specify the application of the medical device. Next level would be verification, which examines if specific product characteristics are fulfilled, then comes validation which examines if the intended use can be reached in a specific use context by a specific user. The user interface specifications that were derived should be evaluated to make sure the design controls that will be implemented are meeting the requirements of the safety relevant to the user interface. 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. But which tools are suited best? The risk of design defects in the user interface, the correction of which can be time-consuming and expensive, is lower. 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.
