EXECUTIVE SUMMARY
ISO 14971 is an international
risk management
standard for
medical devices (including in vitro
diagnostic medical devices).
It defines a
set of medical device
risk management requirements.
The purpose of this standard is to help
manufacturers to establish
a
medical device
risk management
process that can be used to
identify
hazards, to estimate and
evaluate risks, and to implement
and monitor
the effectiveness of
risk control measures.
ISO 14971 was first published in 2000.
This second edition was
officially published on March 1,
2007. It cancels and replaces the first
edition. ISO 14971 was developed
because no standard existed at the
time and
because regulators
throughout the world wanted manufacturers
to apply risk management to their
medical devices. When the standard
development process began it soon
became obvious that “absolute
safety” was not achievable.
In addition, it became clear that
product safety standards cannot
deal with all
possible risks. There are just too many products and
applications for a product
oriented approach to work effectively.
Because of
this, and because there was a great need to manage
risks
throughout the entire product life-cycle, the standards
development committee decided to prepare ISO 14971.
SCOPE OF STANDARD
ISO 14971 applies to all medical device manufacturers and all
medical devices and should be used to manage risk throughout
all stages
of the product life-cycle from initial concept right through
to final
disposal. It applies to product design, production, and all
post-production activities. Since risks can be introduced throughout
the
product life-cycle and since risks that emerge at one point can
often be
controlled at a completely different point, ISO 14971
must be used
throughout the product’s entire existence.
However, this standard does not apply to clinical decision
making.
Whether or not a medical device should be used in the context of
a
particular clinical procedure is a matter of judgment. Such judgments
are usually made by qualified health care professionals and are not
regulated by this international standard.
REGULATORY ENVIRONMENT
ISO 14971 is widely recognized as the official standard for
medical
device risk management. Regulators in most major markets expect
medical device manufacturers to use this standard to manage risk.
ISO
14971 has been officially recognized by the U.S. FDA and by
Health
Canada. In addition, the European Union has adopted it as
a
harmonized standard and Australia and Japan have accepted it
as the
official standard for medical device risk management.
Medical device risk management is now
mandatory in most
countries and regions of the world. Every regulated medical device
manufacturer now needs to be able to prove to regulators that they
use
risk management methods to control risk and to ensure that
their
products are safe.
CERTIFICATION
ISO 14971 does not expect medical device manufacturers to
become certified. You can simply use the standard to manage
risk and
then declare that you are in compliance (if you can
demonstrate that
this is in fact true).
However, regulators may require certification and your
customers
may be more impressed if an independent registrar
(certification body)
has confirmed that you use the standard to manage
risk and that you
actually are in compliance.
While this standard does not expect you to become certified,
several registrars now offer certification services. Some of these
include
BSI,
Underwriters Laboratories,
Intertek, and
SGS.
STEP-BY-STEP OVERVIEW
ISO 14971 describes a risk management process
(Parts 3 to
9) and is organized in the following way:
3. Establish your risk management framework.
4. Perform a
risk analysis for each medical device.
5. Evaluate risk for each
identified hazardous situation.
6. Develop
risk control measures when
risk must be reduced.
7. Evaluate the overall
residual risk posed by
each device.
8. Review risk management process and prepare report.
9. Monitor device during production and post-production.

material in diagrammatic form.
It highlights key decision points and

the steps that should be taken.
