Key Terminology in ISO 14971
Understanding key terminology is crucial for effective implementation of ISO 14971․ A “hazard” is a potential source of harm․ “Risk” is the combination of the probability of occurrence of harm and the severity of that harm․ “Risk management” is the systematic application of management policies, procedures, and practices to the tasks of analyzing, evaluating, controlling, and monitoring risk․
“Risk analysis” involves identifying hazards and estimating the associated risks․ “Risk evaluation” compares the estimated risks against given risk acceptance criteria․ “Risk control” includes implementing measures to reduce risks to acceptable levels․ “Residual risk” is the risk remaining after risk control measures have been implemented․
“Severity” refers to the extent of harm that could result from a hazard․ “Probability” is the likelihood of a hazard occurring․ “Acceptable risk” is a risk that has been reduced to a level that can be tolerated by the organization, having regard to its legal obligations and policy․ Knowing these definitions is essential․
These terms provide the base for understanding․
Risk Management Process According to ISO 14971
The risk management process outlined in ISO 14971 is a systematic approach to ensure medical device safety․ It begins with establishing a risk management plan, defining the scope, responsibilities, and resources․ Hazard identification follows, aiming to identify potential sources of harm associated with the device․
Next, risk analysis estimates the probability and severity of each hazard․ Risk evaluation compares these estimates against acceptability criteria․ If risks are unacceptable, risk control measures are implemented to reduce them, prioritizing inherently safe design and protective measures․
After implementing controls, residual risk is evaluated․ The overall residual risk must be acceptable․ Risk management activities are documented throughout the process․ Finally, post-market surveillance monitors device performance, feeding back into the risk management process for continuous improvement․
This iterative process ensures devices remain safe throughout their lifecycle․ The plan must cover all these points and be very clear․ The review of the risk is also important․
Hazard Identification
Hazard identification is a crucial step in the ISO 14971 risk management process․ It involves systematically identifying potential sources of harm (hazards) associated with a medical device throughout its lifecycle․ This includes considering normal use, foreseeable misuse, and potential failures․
Techniques like brainstorming, hazard checklists, and failure mode and effects analysis (FMEA) can be employed․ The identification process should consider all aspects of the device, including its design, materials, manufacturing processes, intended use, and user interface․
It’s important to consider the perspectives of all stakeholders, including patients, users, and healthcare professionals․ Thorough hazard identification forms the foundation for subsequent risk analysis and evaluation․ Incomplete or inaccurate hazard identification can lead to inadequate risk controls and potential harm to patients․
The environment in which the device will be used should also be considered․
A well-documented and comprehensive list of hazards is the key outcome․ The list should be regularly reviewed and updated as new information becomes available․ Also, you must be very accurate in this phase․
Risk Analysis and Evaluation
Following hazard identification, risk analysis and evaluation are essential steps in ISO 14971․ Risk analysis involves determining the probability of occurrence of each hazard and the severity of the harm it could cause․ This often involves qualitative or quantitative methods to estimate the risk associated with each identified hazard․
Techniques such as fault tree analysis and event tree analysis can be used․ Risk evaluation then involves comparing the estimated risk against predefined acceptance criteria․ These criteria should be based on regulatory requirements, industry standards, and the manufacturer’s risk acceptance policy․
Risks that exceed the acceptance criteria are deemed unacceptable and require further risk control measures; The evaluation should be objective and based on available data and evidence․ It is very important to document the rationale for risk acceptance decisions․
The risk analysis and evaluation should consider the entire lifecycle of the medical device, from design and manufacturing to use and disposal․ Regular review and updating of the risk analysis and evaluation are necessary to ensure its continued validity․ The data must be relevant․
Risk Control Measures
Once unacceptable risks have been identified through risk analysis and evaluation, ISO 14971 requires the implementation of appropriate risk control measures․ These measures aim to reduce the probability of occurrence of harm, the severity of harm, or both․ Risk control measures should be implemented in a specific order of priority․
The first priority is inherently safe design, which involves eliminating hazards or reducing risks through design choices․ If inherently safe design is not feasible, protective measures should be implemented to guard against hazards․ These measures may include guards, interlocks, or other safety features․
If neither inherently safe design nor protective measures are sufficient, information for safety, such as warnings and instructions, should be provided to users․ This includes labeling, training, and user manuals․ The effectiveness of risk control measures should be verified and documented․
Residual risk, which remains after risk control measures have been implemented, must be evaluated to ensure it is acceptable․ If the residual risk is not acceptable, additional risk control measures are required․ The risk control measures must not introduce new risks․
Monitoring and Review
ISO 14971 emphasizes the importance of monitoring and review throughout the entire lifecycle of a medical device․ This includes post-market surveillance activities to collect and analyze data on the device’s performance in the field․ The goal is to identify any new hazards or previously unforeseen risks that may arise during actual use․
Monitoring activities involve gathering information from various sources, such as customer feedback, complaint handling, and regulatory reports․ This data is then analyzed to identify trends and patterns that may indicate potential safety issues․ The results of monitoring activities should be documented and used to update the risk management file․
Periodic reviews of the risk management process are also essential to ensure its effectiveness and relevance․ These reviews should assess the adequacy of risk controls, the accuracy of risk assessments, and the overall performance of the risk management system․ The frequency of reviews should be determined based on the complexity and risk profile of the medical device․
Any changes to the medical device, its intended use, or the manufacturing process should trigger a review of the risk management file․ This ensures that the risk assessment remains current and that appropriate risk control measures are in place․
