- International Acceptance
- US
- Consensus standard for use in submissions and QMS.
- Europe
- For the essential requirements of MDD, AIMD, and IVDD, the device is
presumed to conform with requirements for mitigating and reducing
risks if the RM process conforms to ISO14971:2000, a harmonized
standard.
- Other countries recognizing ISO 14971:2000

|
- The System
- Management Responsibilities
|
|
7
|
- RM is applicable to all stages of the life cycle of the device
- Applies a systematic approach to the process.
- Use of all medical devices entails some degree of risk.
- The process “lives”. It’s not
once and done.
|
|
8
|
- hazard – potential source of harm
- harm – physical injury or damage to the health of people, or damage to
the property or the environment.
- objective evidence – information which can be proven true, based on
facts obtained through observation, measurement, test or other means
- risk – combination of the probability of occurrence of harm and the
severity of that harm
|
|
9
|
- risk control – process through which decisions are reached and
protective measures are implemented for reducing risks to, or
maintaining risks, within specified levels
- risk evaluation – judgment, on the basis of risk analysis, of whether a
risk which is acceptable has been achieved in a given context based on
the current values of society.
- safety – freedom from unacceptable risk
- severity – measure of the possible consequences of a hazard.
|
|
10
|
- Define the policy for determining acceptable risk, taking Standards and
Regulations into account
- Ensure the provision of adequate resources
- Ensure the assignment of trained, qualified personnel (must maintain
records showing person has appropriate qualifications)
- Review results of risk management at defined intervals to ensure
suitability and effectiveness
|
|
11
|
- Scope of the plan, describing the device and life cycle phases for which
plan is applicable
- A verification plan
- Allocation of responsibilities
- Requirements for reviewing risk management activities
- Criteria for risk acceptability
|
|
12
|
|
|
13
|
- Analysis of intended use using Annex A as a basis
- Description of the device/accessory analyzed
- Identification of person who conducted the risk assessment
- Date of the analysis
|
|
14
|
- Description of the intended use AND any reasonably foreseeable misuse
- Listing of qualitative and quantitative characteristics that could
affect safety
- Excellent self-analysis questions can be found in Annex A of the
Directive
|
|
15
|
- You need to compile a list of foreseeable hazards that could lead to a
hazardous situation
- List must be maintained in risk management file
|
|
16
|
- After identifying hazard, risk in normal and fault conditions must be
estimated
- If you can’t estimate risk, possible consequences should be prepared and
include in file
- Methods of risk estimation and other techniques found in Annexes E and F
|
|
17
|
|
|
18
|
- Must evaluate every hazard and determine whether estimated risk is so
low that risk reduction is not required
- Standard does not specify acceptable risk levels
- Compare to medical devices already in use
- Risk can be accepted if benefits outweigh risks
|
|
19
|
- After evaluating hazards, you need to ask:
- Is risk so low that there is no need to consider it?
- Is the risk outweighed by the benefit?
- Is the overall balance of all risks and benefits acceptable?
|
|
20
|
|
|
21
|
- There are two types of failure:
- Random failure
- Systematic failure
- Statistical probability can often be assigned to random failures
|
|
22
|
|
|
23
|
- Need to identify risk control measures that are appropriate for reducing
risk to an acceptable level. Must be evaluated in order of priority:
- Inherent safety by design
- Protective measures in the device or manufacturing process
- Information for safety
- Must be maintained in risk management file
|
|
24
|
- Manufacturer needs to implement risk control measures
- Proof of implementation of measures and verification of effectiveness
must be kept on file
- Residual risk must be evaluated
- Gather data and conduct a risk/benefit analysis
|
|
25
|
|
|
26
|
- Results of the risk management process must be contained in risk
management report which needs to contain:
- Traceability for each hazard in the risk analysis
- The risk evaluation
- Implementation and verification of risk control measures
- Assessment that residual risk is acceptable
|
|
27
|
- Need to maintain a systematic procedure to review information in
post-production phase and evaluate:
- Previously unrecognized hazards
- Whether the estimate risk from a hazard is no longer acceptable
- If the original assessment is otherwise invalidated
|

|
|
40
|
- Outsourcing
- Many items outside manufacturer’s direct control. (sterilization,
tooling, test, design, manufacturing)
- RM can be applied to outsourced operations to determine levels of
control
|
|
41
|
- Planning
- Both the QMS and the RMS span the entire lifecycle of the medical
device.
- Several opportunities to integrate RM requirements into the QMS – the
daily functioning of the business.
|
|
42
|
- Design and Development
- An area of strong ties to the RM process
|
|
43

|
|
47
|
- Traceability
- Risk data can be used to determine which components require
traceability
|
|
48
|
- Purchasing Controls and Acceptance Activities
- Supplier selection, evaluation and re-evaluation criteria should be
tied to risks and hazards associated with purchased products and
services.
- Acceptance criteria (and specifications) for purchased products and
services should be identified risks and risk control measures.
|
|
49
|
- Production and Process Controls
- Another area of strong ties to RM process
|
|
50
|
- Production and Process Controls
- Manufacturing processes source of identified hazards.
- equipment, processes, environment, personnel, etc.
|
|
51
|
- Production and Process Controls

- the likelihood of the failure
- controls to detect and prevent failure or causes
- Process validation and revalidation may be tied to RM activities.
|
|
52
|
- Production and Process Controls
- Process validation and revalidation may be tied to RM activities.
|
|
53
|
- Servicing
- Repair and maintenance activities
- RM activities should provide input into preventive maintenance,
servicing, etc.
|
|
54
|
- Corrective and Preventive Action
- CA/PA is a cornerstone of the QMS.
- Repository for events and issues.
- Regular review and comparison.
|
|
55
|
- See Attachment 3 for a larger view.
|
|
56
|
|
|
57
|
- Build a case for inclusion of ISO 14971 in the internal auditing
process.
- Provide suggestions for advanced audit checklist items.
|
|
58
|
|
|
59
|
- Self Evaluation Integral in Achieving Excellence
- World-class operations actively seek out best practices.
- World-class operations aren’t afraid to “peek under the hood” and
self-analyze.
- Auditing the RM process enables this to occur.
|
|
60
|
- Auditing is an Integral Part of Continual Improvement
- “Plan / do / check / act” cycle.
- Auditing is a primary tool for checking the system.
|
|
61
|
- Build Management Awareness
- Many Sr. Managers will read audit reports – increasing awareness.
- Including comments or nonconformities on the standard (depending on
scope) will enable management to monitor the status of system and
provide inputs to management review.
|
|
62
|
- Regulator Buy-In / Expectations
- Europe
- Presumed Conformity to Essential Requirements for AIMD, MDD and IVDD.
- Many NB’s do not accept technical files for review unless ISO
14971-compliant RM Report is included.
- US
|
|
63
|
|
|
64
|
- Assumptions
- Goal is to provide suggestions which will indicate if a system is
working, broken or a figment of management’s imagination.
|
|
65
|
