3. Increasing Complexity Humans are exceptionally good at dealing with complexity, HOWEVER, sometimes the rational action in the moment can have unintended consequences

4. What is Human Factors (HF)? Ergonomics (or human factors) is the scientific discipline concerned with the understanding of interactions among humans and other elements of a system, and the profession that applies theory, principles, data and methods to design in order to optimize human well-being and overall system performance. International Ergonomics Association (IEA)

5. Goals of incorporating HF • Provide the best possible user experience • Combat the medical error problem1 • Reduce risk of use errors resulting in harm or compromised medical care Original design Optimized design Low High Risk Level 1www.ncbi.nlm.nih.gov/books/NBK225187

7. Regulatory Basis for Human Factors in Medical Devices 21 CFR 820.30 Design controls Design input Address intended use of the device, including needs of user/patient Design verification Confirm design output meets design input requirements Design validation Ensure device conforms to user needs…and includes testing of production units under actual or simulated use testing Product development

8. Regulatory Basis for Human Factors in Medical Devices

9. 2016 FDA CDRH HF Device Guidance Aims to clarify expectations around: • applying HFE to medical device development, • when to submit a HF report for a pre-market submission, and • the content of the HF report

10. User Cognitive Processing Information Perception Control Action Use error Hazard USER INTERFACE Device Output Input Processing & Reaction Critical task: A user task which, if performed incorrectly or not performed at all, would or could cause serious harm to the patient or user, where harm is defined to include compromised medical care. Adapted from Redmill and Rajan, 1997

11. HF considerations in Digital Health • Mobile Medical Applications • Three levels: Regulatory oversight, enforcement discretion, and apps that are not medical devices. • HF will be required depending on the evaluated risk level.

12. HF considerations in Digital Health Define intended users, use environments & UI Identify use-related hazards; identify and categorize critical tasks Develop and implement risk mitigation/control measures Validate use safety and effectiveness Document HFE/UE process
