Nothing works without software in the planning, control and implementation of medical technology projects. The feedback from the subjects is documented and evaluated if the medical device deign meets the requirements of the user safety and satisfaction. With an MDSAP-audit only! This standard drives much of the usability engineering work done by Emergo by UL’s Human Factors Research & … Consequently, delivery of therapy may suffer or lack completely and patient safety may be in danger. 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. Usability Engineering process during and/or when the device is placed in the market, involves the following tasks:-. 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. 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. 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. With our team of experienced physicists, engineers, computer scientists, process engineers and consultants, every one of our projects reaffirms our ambition to find innovative solutions and help our customers succeed in the market. Specifies a process for a manufacturer to analyse, specify, design, verify and validate usability, as it relates to safety of a medical device. If you want to learn about usability, then reading a standards document may not be the easiest starting point. It also indicates that a system should work the way users expect it to. This standard has been revised by IEC 62366-1:2015. The risk of design defects in the user interface, the correction of which can be time-consuming and expensive, is lower. It describes from the point of view of the FDA what methods need to be applied to analyse risks, how to decline them, what characteristics the user and the user environment have and how usability testing is planned, implemented and documented. 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. 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 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. Device manufacturers are responding by actively initiating human factors and usability engineering to many high priority devices. 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. A usable medical device also has advantages outside of regulatory requirements. If you do not agree, you can change the following settings. 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. In the United States (through the FDA) it has been important for many years to apply the usability aspects during the product development; you should be able to provide documentation to prove that the usability aspects have been applied. If a medical device is lacking usability, there is a higher possibility that errors occur, or the use of the device might be slower, i.e. Further, the technical documentation should contain the results of the product verification and validation, especially usability related activities, like formative and summative evaluation. Feedback from users and information about problems or errors need to be collected and evaluated, as well. Replace NOTE 1 … Section 1 is the introduction. The formative evaluation plan should address the objective, evaluation method and the type of user interface that is being evaluated and the criteria of acceptability. 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. 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. Summative evaluations are conducted only after the completion of the formative evaluations. In comparison, the concept of usability engineering is quite new to the medical device 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). IEC TR 62366-2:2016, Medical devices – Part 2: Guidance on the application of usability engineering to medical. Medical devices to be safe and easy to handle is the requirement across all the regulations. Other related sections refer to the output of usability requirements such as required user … Usability Engineering is one of the important processes, part of the design and development of the medical devices. User interface characteristics related to the safety should be identified considering the primary operating functions of the device which the user or patient is continuously using to interact with the medical device to achieve the intended use of the medical device. This standard is in some way recognised by both, the FDA and the MDR (it will be part of the harmonised standards). 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. Patrick Blumentritt Head of Consulting North, Quality Management & Regulatory Affairs, Tel.

Created by > Usability Engineering. 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. From the idea to development and approval to series production – everything from one source – made in Germany. 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. When it comes to healthcare and medical devices, usability has a great impact on it. 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 standard describes a Usability Engineering Process with 9 stages: 1. The formative evaluations can be module by module, developed stage wise. Specify the application of the medical device. Specifies a process for a manufacturer to analyse, specify, design, verify and validate usability, as it relates to safety of a medical device. 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. In this stage, you identify the most important characteristics relating to the use of the device (such as the intended medical indication, patient population, the intended user profile, conditions of use, the device's operating principle etc.) Even though the other participating countries, such as the U.S., Brazil, Japan and Australia, do not have an audit obligation (yet), we cannot avoid it there. Although, it is not to underestimate what impact usability has on healthcare. The MDR comes into force on 26 May - and with it the UDI regulation. At first sight, people are often confused by the term “usability engineering”, not knowing what to make out of it. AAMI HE75, Human factors engineering – Design of medical devices, Clause 9, Usability Testing, provides an excellent guide to the types of formative evaluations that are useful in early device UI development such as cognitive walkthroughs, heuristic evaluations, and walk-through-talk-through usability tests. 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. What we know about it …, Product development of medical devices is subject to its own rules. 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. Abstract .
