Application of risk management for IT-networks incorporating medical devices — Part 2-1: Step by Step Risk Management of Medical IT-Networks; Practical Applications and Examples
IEC/TR 80001-2-1:2012(E), which is a technical report, is a step-by-step guide to help in the application of risk management when creating or changing a medical IT-network. It provides easy to apply steps, examples, and information helping in the identification and control of risks. All relevant requirements in IEC 80001-1:2010 are addressed and links to other clauses and subclauses of IEC 80001-1 are addressed where appropriate (e.g. handover to release management and monitoring). This technical report focuses on practical risk management. It is not intended to provide a full outline or explanation of all requirements that are satisfactorily covered by IEC 80001-1. This step-by-step guidance follows a 10-step process that follows subclause 4.4 of IEC 80001-1:2010, which specifically addresses risk analysis, risk evaluation and risk control. These activities are embedded within the full life cycle risk management process. They can never be the first step, as risk management follows the general process model which sets planning before any action.

Practical applications and examples
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC 80001-2-1, which is a technical report, has been prepared by a Joint Working Group of
subcommittee 62A: Common aspects of electrical equipment used in medical practice, of IEC
technical committee 62: Electrical equipment in medical practice and ISO technical committee
215: Health informatics.

INTRODUCTION
This technical report is a step-by-step guide to help in the application of RISK MANAGEMENT
when creating or changing a MEDICAL IT-NETWORK. It provides easy to apply steps, examples,
RISKS. All relevant requirements in
and information helping in the identification and control of
IEC 80001-1:2010 are addressed and links to other clauses and subclauses of IEC 80001-1
are addressed where appropriate (e.g. handover to release management and monitoring).
This technical report focuses on practical RISK MANAGEMENT. It is not intended to provide a full
outline or explanation of all requirements that are satisfactorily covered by IEC 80001-1.
This step-by-step guidance follows a 10-step PROCESS that follows subclause 4.4 of
IEC 80001-1:2010, which specifically addresses RISK ANALYSIS, RISK EVALUATION and RISK
CONTROL. These activities are embedded within the full life cycle RISK MANAGEMENT PROCESS.
They can never be the first step, as RISK MANAGEMENT follows the general PROCESS model
which sets planning before any action.
For the purpose of this technical report, “prerequisites” as stated in subclause 1.3 are
considered to be in place before execution of the 10 steps. Also, it is well understood that all
MEDICAL IT-
steps outlined in this technical report should have been performed before any new
NETWORK can go live or before proceeding with a change to an existing MEDICAL IT-NETWORK.
It is emphasized that subclause 4.5 of IEC 80001-1:2010 “CHANGE RELEASE MANAGEMENT and
CONFIGURATION MANAGEMENT” explicitly includes and applies to new MEDICAL IT-NETWORKS, as
well as changes to existing networks.
This technical report will be useful to those responsible for or part of a team executing RISK
when changing or creating (as the ultimate change) a MEDICAL IT-NETWORK.
MANAGEMENT
MEDICAL DEVICES in the context of IEC 80001 refer to those MEDICAL DEVICES that connect to a
network.

Practical applications and examples
1 Scope
This technical report provides step-by-step information to aid RESPONSIBLE ORGANIZATIONS in
implementation of the RISK MANAGEMENT PROCESS required by IEC 80001-1. Specifically, it
details the steps involved in executing subclause 4.4 of IEC 80001-1:2010 and provides
guidance in the form of a study of RISK MANAGEMENT terms, RISK MANAGEMENT steps, an
explanation of each step, step-by-step examples, templates, and lists of HAZARDS and causes
to consider.
The steps outlined within this technical report are considered to be universally applicable.
Application of these steps can be scaled as described within this document.
