It also indicates that a system should work the way users expect it to. 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but it gives many lists with requirements and refers to the important regulations and the IEC 62366 (in the meantime superseded by IEC 62366-1). Abstract . The story begins with a plan, as usual in the quality world.The usability engineering plan shall describe the process and provisions put in place. Gaining approval for medical devices is complex and quite often also confusing. Several amendments to the text of the international standard IEC 62366-1: Application of usability engineering to medical devices have been published in June 2020. Annex D of IEC 62366 also IEC TR 62366-2:2016, Medical devices – Part 2: Guidance on the application of usability engineering to medical. The feedback from the subjects is documented and evaluated if the medical device deign meets the requirements of the user safety and satisfaction. 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. Specifies a process for a manufacturer to analyse, specify, design, verify and validate usability, as it relates to safety of a medical device. The usability engineering plan can be a section of the software development plan, or a separated document.The usability engineering plan describes the following to… From the idea to development and approval to series production – everything from one source – made in Germany. The MDR comes into force on 26 May - and with it the UDI regulation. This USABILITY ENGINEERING (HUMAN FACTORS ENGINEERING) PROCESS permits the MANUFACTURER to assess and mitigate RISKS associated with CORRECT USE and USE ERRORS, i.e., NORMAL USE. Usability Testing. 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. Implement measurements that take account of the intended purpose, users and environmental conditions. A further advantage is the higher acc… Use specifications include the intended use of the medical device, intended patient population, type and site of interaction with the user, intended users [users could be medical staff or the patient and in some cases, both patient and medical staff], use environment and operating principle. That is why a thoroughly implemented usability process is essential to every manufacturer of medical devices. normal use. Every product is unique – the mandatory tasks and measures for entering the market need to be specified individually. Device manufacturers are responding by actively initiating human factors and usability engineering to many high priority devices. The risk of design defects in the user interface, the correction of which can be time-consuming and expensive, is lower. 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. Summative evaluations are conducted only after the completion of the formative evaluations. Whilst the Medical Device Directive (MDD) had a few mentions of the word “usability”, it was not back in 1993 when it was written, a commonly used term. The Usability Engineering PROCESS addresses USER interactions with the MEDICAL DEVICE mostly during the following processes related to use of the medical device. Medical Device Usability Engineering is also known as Human Factors Engineering. We develop individual solutions in partnership with our customers around the world, quickly leading to success. 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. In the past years the IEC 62366 was replaced by the IEC 62366-1:2015 + COR1:2016 Medical devices - Part 1: Application of usability engineering to medical devices. It has issued a guidance document with the title “Applying Human Factors and Usability Engineering to Optimize Medical Device Design”. A very good Usability Engineering File [UEF] will have all the documents separate and stored within the UEF. The organization of the guidance is similar to an ISO standard. Global Human Factors and Usability Engineering for Medical Devices THAY Medical are a specialist Human Factors and Usability Engineering consultancy who partner with clients to focus on medical device users. Although, it is not to underestimate what impact usability has on healthcare. Health practices today are heavily dependent on the use of medical equipment, medical instruments and medical technology for both the observation and treatment of patients. 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. When it comes to healthcare and medical devices, usability has a great impact on it. Read the article to learn why. It’s important to note that usability engineering shall be applied to all medical device, not exclusively active devices. MDR (EU) 2017/745 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. 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. Medical devices must meet certain requirements to be marketed in Europe and the United States. Almost all the Medical Device Regulations across the globe has recognized Usability Engineering requirements within their regulatory framework. Write what you do, do what you write. 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. Nothing works without software in the planning, control and implementation of medical technology projects. 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. It is provided by several institutions and their regulations, the most frequent ones are the FDA, the MDR and the standard IEC 62366-1. Feedback from users and information about problems or errors need to be collected and evaluated, as well. 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. 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. Specify the application of the medical device. Poor design and usability of frequently used functions —red routes— can seriously impact safety by increasing the pr… 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. Tools are needed to develop efficiently and with minimal errors. For approval, you as a manufacturer must prove that the operation of your medical devices is safe. The Usability Engineering File should contain all the relevant documents arising from the processes as described in the Usability Engineering process. Usability engineering, also called as human factors engineering, is nothing but the interaction between the user and the user interface of the medical devices. The international standard IEC 62366 medical devices - Application of usability engineering to medical devices is a standard which specifies usability requirements for the development of medical devices.It is harmonized by the European Union (EU) and the United States (US), and therefore can be used as a benchmark to comply with regulatory requirements from both these markets User interface specifications are the testable requirements relevant to the user interface. 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. The choice is left to the manufacturer, the documents could be maintained however that is feasible and practical based on the complexity of the medical device.

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. Usability in Medical Engineering Interactive products in medical engineering should not only be easy to use, they must also meet high safety standards. 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. Patrick Blumentritt Head of Consulting North, Quality Management & Regulatory Affairs, Tel. Created by > Usability Engineering. This standard is in some way recognised by both, the FDA and the MDR (it will be part of the harmonised standards). 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. If you agree, please click ok. In this way, the manufacturer receives valuable information at an early stage, which can shorten the time to market. This USABILITY ENGINEERING (HUMAN FACTORS ENGINEERING) PROCESS permits the MANUFACTURER to assess and mitigate RISKS associated with NORMAL USE, i.e., CORRECT USE and USE ERROR. In addition… In the past years the IEC 62366 was replaced by the IEC 62366-1:2015 + COR1:2016 Medical devices - Part 1: Application of usability engineering to medical devices. The compliance to the standard, IEC 62366-1:2015 is evaluated against the documents stored in the UEF. 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. Summative evaluations are conducted in the simulated environment or in a real use case scenario with the subjects being the users and/or the patients as defined in the use specifications. Usability may be evaluated by understanding the characteristic of the USER INTERFACE that facilitates use and thereby establishes EFFECTIVENESS, EFFICIENCY and USER satisfaction in the intended USE ENVIRONMENT. Further, the technical documentation should contain the results of the product verification and validation, especially usability related activities, like formative and summative evaluation.
