[FREE WHITE PAPER] Measurable Objectives and Acceptance Criteria to Verify Device Safety and Performance

Overview

This white paper is a companion piece to our popular webinar where we cover strategies to verify device safety and performance in the clinical evaluation of medical and in vitro diagnostic (IVDs) devices. This white paper should help you with identifying meaningful safety and performance measures for clinical or performance evaluation and with defining acceptance criteria parameters to determine the acceptability of benefit-risk as mandated by Medical Device Regulation (MDR) 2017/745 and In Vitro Diagnostic Regulation (IVDR) 2017/746.

Establishing your device’s safety and performance is a critical component of the clinical evaluation process. However, how to use the state of the art section within the Clinical Evaluation Report (CER) and Performance Evaluation Report (PER) to establish the device’s safety and performance objectives and acceptance criteria can seem ambiguous.

Solution to Verify Device Safety and Performance

First, clearly understand the difference between safety and performance objectives and acceptance criteria. Then, use…

Risk Benefit Analysis and Residual Risk are Key Components of ISO 14971:2019

Author: Nupur Srivastava, PhD  | December 7, 2020

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

Medical Device Manufacturers Transitioning to ISO 14971:2019 Need to Perform a Gap Analysis and Create a Cross-Functional Risk Management Team

Author: Nupur Srivastava, PhD  | November 18, 2020

There has been a lot of discussion on the updated International Organization for Standardization (ISO) 14971:2019,  and experts agree that medical device manufacturers need to perform a gap analysis and create a cross-functional team to meet these risk management requirements.  

Risk management plays a critical role in getting medical devices into the market, and ISO 14971:2019 “was designed to better align with medical device regulations around the world.” The global regulatory landscape has been very dynamic around the areas of risk management, as well as safety and performance. 

Tips on Putting Risk Management into Quality Systems During the Transition to ISO 14971:2019 

Two experts shared insights during an interview with Medtech Insight. Jos Van Vroonhoven, convener of ISO Technical Committee 210, Joint Working Group 1 (TC210/JWG1) and a senior manager for standardization for device giant Philips Healthcare, and Don Powers, a member of ISO TC210/JWG1 and long-time industry expert, said that the third edition of ISO 14971 provides more precise guidance and greater detail in the application of risk management concepts.
