There are some clarifications in order.
ISO 14971:2007 has not been updated. The international version remains at the 2007 revision and is among the recognized standards in both the US and Canada. What has changed is EN ISO 14971:2012 which seeks to address discrepancies between the international standard and the EU product directives related to medical devices.
In terms of ALARP, the content deviation refers to As Far As Possible, which is usually stated as AFAP. It concludes, “Accordingly, manufacturers and Notified Bodies may not apply the ALARP concept with regard to economic considerations.” ALARP is a risk reduction methodology (not the name of a risk region) composed of technical means and economic means. The content deviation eliminates economic means (making the device an unsound economic proposition) from the tool box. It does not change to acceptability criteria or the need to reduce a risk to an acceptable level.
You say, “user labeling is to provide no primary risk mitigating value”. First, the correct term is risk reduction, not mitigation. The standard doesn’t use the word mitigation, since it has a different meaning.
The content deviation is about residual risk, not using information for safety as a risk reduction measure. In fact, for the MDD, there is a content deviation that requires information for safety as a risk reduction measure. This is described as the cumulative approach to the application of risk reduction options. The content deviation in question, for the MDD, is about a requirement to inform users about the residual risks, and concludes that manufacturers cannot use this information, i.e., the residual risk information, to reduce risk. The misunderstanding often arises from failure to distinguish between information for safety and disclosing residual risk. See Annex J of the standard for a discussion of the differences.

hey all,
As we all know, the recently updated ISO 14971 seeks to implement ALAP, rather than ALARP. Moreover user labeling is to provide no primary risk mitigating value.
I was just wondering what techniques folks may be choosing to use to document those mitigations that we rely upon at the operational/user level. I.e. Our user guides may convey the need to for users to comply with certain best practices or professional industry standards of care. Also, even a blind man can see that user warnings in our labeling are required to adequately reduce risk in certain cases. It's not very effective to attempt to assess product risks without considering user practices and our warnings intended to ensure reasonable practices. Training, which is technically based on user labeling, provides a wealth of actual mitigations. Yes, engineering controls are the most valuable mitigation, but we can't leave out the need to ensure that the user is adequately competent and aware of safe device use requirements.
We most certainly need to consider such mitigations to adequately reduce risk to a reasonable level, so we can't practically dismiss them from our risk management practices.
Anyone have thoughts on the matter or clearly effective ways of meeting the standards while still addressing risk to the finest grains of appropriateness?
