Hi
1. What is the relationship between the USE SCENARIO as defined in IEC 62366 and the (CRITICAL) TASK defined in the FDA Human Factors Guidance? Is it the same or does a USE SCENARIO contain TASKS (as defined by the FDA)?
2. Similarly, what is the relation ship between a TASK as in the IEC 62366 and a TASK defined in the FDA Human Factors Guidance?
3. Consider a USE SCENARIO that contains a TASK which could lead to serious HARM (CRITICAL TASK). In my current understanding, the IEC 62366 requires to test the entire USE SCENARIO while the FDA is satisfied if the CRITICAL TASK itself is tested. Is that a correct understanding?
My understanding of IEC 62366 is that a USE SCENARIO comprises TASKS. If one of those TASKS could lead to serious HARM, the entire USE SCENARIO must be tested in the summative evaluation.
On the other hand, the FDA Human Factors Guidance requires the manufacturer to identify CRITICAL TASKS (TASKS that could lead to serious HARM). Those must then be tested in the summative evaluation.
Amongst others, the IEC 62366 defines the following terms
- TASK: one or more USER interactions with a MEDICAL DEVICE to achieve a desired result
- USE SCENARIO: specific sequence of TASKS performed by a specific USER in a specific USE ENVIRONMENT and any resulting response of the MEDICAL DEVICE
- HAZARD-RELATED USE SCENARIO: USE SCENARIO that could lead to a HAZARDOUS SITUATION or HARM
Amongst others, the FDA Human Factors Guidance defines the following terms
- TASK: Action or set of actions performed by a user to achieve a specific goal.
- USE SCENARIO: -
- 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.
Best Regards
