The International Organization for Standardization (ISO) 14971:2019 places more emphasis on the risk to benefit ratio of medical devices, asking manufacturers to show that their device is not only safe but also provides a medical benefit. The reference to benefit is included throughout the standard, and the definition for “benefit” is included for the first time.  

ISO 14971:2019 Definition of Benefit: a positive impact or desirable outcome of the use of a medical device on the health of an individual, or a positive impact on patient management or public health. 

As outlined in the standard, risk has two key components:  

  • The probability of occurrence of harm; and 
  • The consequences of that harm, that is, how severe it might be. 

The newest ISO 14971:2019 standards emphasize that manufacturers need to demonstrate that the benefits outweigh the risks, as well as mitigating risks. Clause 7.4 of ISO 14971:2019 has even been retitled “Risk/Benefit Analysis” to align with regulatory changes.   

Examples “benefits” provided ISO 14971:2019: 

  • Positive impact on clinical outcome 
  • Patient’s quality of life 
  • Outcomes related to diagnosis 
  • Positive impact from diagnostic devices on clinical outcomes 
  • Positive impact on public health
