Risk Analysis Steps

• Why Risk Management

• Why ―Communicate‖

• Doing a Hazard Analysis...quickly

• How to ―Communicate‖ to ―Them‖

Page 6: Risk Analysis

What is important

• It’s about the Specs!

• “A problem well defined is a

problem half solved.”

• John Dewey

What does Quality ―control‖?

Page 8: Risk Analysis

8

Quality

• Does not Design.

• Does not Manufacture.

• Does not Distribute.

• Use? Possibly.

• Words – No.

• Control? Yes.

Again, what does quality

―control‖?

• ISO 11540:1993 - Caps for writing and marking instruments

intended for use by children up to 14 years of age -- Safety

requirements

• Specifies safety requirements for cap size, ventilated caps

(vent area, air flow) and marking. Annex A describes the

test for air flow. Caps which do not comply should have

the instrument or its packaging labelled with a warning as

to the dangers of asphyxiation from pen caps.

• ASTM D4236 - 94(2005) Standard Practice for Labeling Art

Materials for Chronic Health Hazards

• Scope 1, 1.1... chronic health hazards known to be

associated with a product or product component(s), when

the component(s) is present in a physical form, volume, or

concentration that in the opinion of a toxicologist (see

2.1.11) has the potential to produce a chronic adverse

health effect(s).

Page 18: Risk Analysis

What is Usability

• Usability is a characteristic of the User Interface that

establishes Effectiveness, Efficiency, ease of User learning and

User satisfaction.

• Medical practice is increasingly using Medical Devices for

observations and treatment of patients. Use Errors caused by

inadequate Medical Device Usability have become an

increasing concern. Many of the Medical Devices developed

without applying a Usability Engineering Process are non-

intuitive, difficult to learn and to use.

• The Usability Engineering Process is intended to achieve

reasonable Usability, which in turn is intended to minimize Use

Errors and to minimize use-associated Risks.

18

Page 19: Risk Analysis

What is Usability

• The Usability standard specifies a Process for a Manufacturer

to analyze, specify, design, Verify and Validate Usability, as it

relates to Safety of a Medical Device. The Engineering

Process assesses and mitigates Risks caused by Usability

problems associated with Correct Use.

• If the Usability Engineering Process has been complied with

and the acceptance criteria documented in the Usability

Validation plan have been met then the Residual Risks are

presumed to be acceptable.

Risk Management System

• ISO 14971: Medical devices — Application of risk

management to medical devices

• Selected definitions

• Risk Management Sections

• Areas that feed into Risk Management

• Performing a Risk Analysis

Page 22: Risk Analysis

22

Risk

• Risk has two components:

• a) the probability of occurrence of harm;

• b) the consequences of that harm, that is, how

severe it might be.

Page 23: Risk Analysis

23

Definitions

• Risk (as defined by dictionary.com) –

• exposure to the chance of injury or loss; a

hazard or dangerous chance

• harm -

• physical injury or damage to the health of

people,

• or damage to property or the environment

• hazard - potential source of harm

Page 24: Risk Analysis

24

Definitions Cont’d

• hazardous situation - circumstance in

which people, property, or the environment

are exposed to one or more hazard(s)

• New consideration

• residual risk - risk remaining after risk

control measures have been taken

• Note: not mitigation

Page 25: Risk Analysis

25

Definitions Cont’d

• risk - combination of the probability of occurrence

of harm and the severity of that harm

• risk analysis - systematic use of available

information to identify hazards and to estimate the

risk

• NOTE Risk analysis includes examination of

different sequences of events that can produce

hazardous situations and harm.

Page 26: Risk Analysis

Do you want more definitions?

• Pressure is identifying a problem before launch!

• Yes

• No

Page 27: Risk Analysis

27

More

• risk assessment - overall process comprising a

risk analysis and a risk evaluation

• Risk analysis + Risk evaluation

• risk control - process in which decisions are made

and measures implemented by which risks are

reduced to, or maintained within, specified levels

Page 28: Risk Analysis

28

More

• risk estimation - process used to assign values to

the probability of occurrence of harm and the

severity of that harm

• risk evaluation - process of comparing the

estimated risk against given risk criteria to

determine the acceptability of the risk

Page 29: Risk Analysis

29

More

• risk management - systematic application of

management policies, procedures and practices

to the tasks of analyzing, evaluating, controlling

and monitoring risk

• risk management file - set of records and other

documents that are produced by risk

management

• safety - freedom from unacceptable risk

Page 31: Risk Analysis

31

Risk Control Order

• ―...risk control options in the priority order listed...‖

a) inherent safety by design;

b) protective measures in the medical device itself

or in the manufacturing process;

c) information for safety.

Risk Management Report

• Prior to release for commercial distribution

• ―Audit‖ the risk management process.

• Ensure that:

• the risk management plan has been

appropriately implemented;

• the overall residual risk is acceptable;

• appropriate methods are in place to obtain

relevant production and post-production

information.

Page 40: Risk Analysis

40

Risk Management Report Cont’d

• The results of this review shall be recorded as the

risk management report and included in the risk

management file.

• The responsibility for review should be assigned

in the risk management plan to persons having

the appropriate authority.

• Compliance is checked by inspection of the risk

management file.

Consider the following order

• Usability Risk Analysis • Only focus is Use, User, and Hazardous Situations

• Design Risk Analysis • Only focus is Design

• Usability is Input to Design

• Process Risk Analysis • Only focus is Processes

• IFU/Labels • Perform Usability Design Review

Page 48: Risk Analysis

Communicating

• Telling good news is easy!

• Keeping bad news quiet is easy!

• Telling bad news is the hard!

Page 63: Risk Analysis

63

What I Look For

• Facts...not Fiction

• Solutions...not the problem(s)

• Remember one of the 1st slides?

• Timing, $$, resources

• Impact on the Business.

• Recovery strategy & solutions

Page 64: Risk Analysis

64

Example

1. A ―clearly defined‖ problem statement

2. Action plan

• Containment + Corrective + Preventive

3. Solution (or high likelihood options)

4. Non-people resources (Est. $$’s)

5. People resources needed for success

6. Timing - estimated completion date

7. Impact of the ―do nothing‖ option

• Without mentioning regulations or agencies?

Page 65: Risk Analysis

―How‖ is the Risk standard set?

• Who

• How / Where

• When

• Why

Page 66: Risk Analysis

66

Who ―sets‖ the standard?

• Management (Them...careful We are Them)

• By approval of the Risk Management

Procedure

• By review of information provided at

Management Review

• Assumes information is being provided

• By supporting and implementing related

change
