Our services

Human Factors Integration & Strategy

Integration of HF activities within a business is vital to successful product development. Rebus Medical has experience of strategically placing HF at the heart of our clients’ medical device design process. Our approach delivers regulatory compliance against key standards including ANSI / AAMI / IEC 62366-1, ISO 14971 and FDA HF Guidance whilst effortlessly dovetailing with existing procedures, systems and organisational structures. 

Formative Human Factors Studies

Formative evaluations add value by identifying use-related risks, gaining insight into user needs and assisting in the planning of Validation studies. Our team have extensive experience applying a variety of HF techniques, including formative usability studies, expert reviews, cognitive walk-throughs and contextual inquiry. This extensive toolkit allows us to tailor an approach to help our clients build confidence in the design decisions and reduce use-related and commercial risks.

Validation Human Factors Studies

Our team is highly experienced in planning, executing and reporting  HF validation studies (summative testing) for a wide range of devices  for FDA submission and European certification. Scientific rigour, robust protocol design, data integrity, precision planning and robust documentation are prerequisites of our HF studies. All of our study documentation follows guidance from FDA, AAMI, IEC, MHRA and industry best practice. 

Use-Related Risk Management

Establishing and maintaining traceability between Risk Management and HF activities is critical to identifying and mitigating use-related risks. Rebus Medical apply ISO 14971 compliant risk management tools, such as HAZOP, URRA and Fault Tree Analysis, throughout all stages of a medical device development process.  Starting from the earliest concept stages we utilise HF tools such as HTA to map user interactions and define user interface requirements. 

Intended Use Specification

Developing a deep understanding of who will use your device, for what purpose and under what environmental conditions are core principles of HF.  We’ve supported our clients to build this understanding and fill in the gaps that  help to guide development activities. 

Rebus Medical has experience in planning, executing and reporting user needs research studies across global markets. 

HFE Summary Report Writing

A clear, comprehensive, yet concise Human Factors Engineering (HFE) Summary Report represents the very foundation upon which your efforts will be reviewed by Health Authorities and Notified Bodies and holds the key to getting your product to market. HFE Summary Reports must summarise all usability and use related risk management activities throughout the development cycle. We’ve assisted a number of clients in preparing HFE Summary Reports, ready for submission.
