Overview Why do we need a formal approach to IT safety?

Clinicians and Safety Engineers: a marriage made in heaven

Thoughts to provoke

Why do we need a formal approach

to IT safety?

•Airbus – first fly by

wire aircfraft

•Safety controls over

ridden to allow low

level pass (30m)

•Pilot fights software

for control (s/ware in

landing mode) 1988

It could never happen to us?

"Overrides of Medication Alerts in Ambulatory Care," Archives of Internal Medicine,

Feb. 9 2009 (archinte.ama-assn.org/cgi/content/abstract/169/3/305)

Physicians ignore electronic drug-safety alerts more than 90% of the time. The rate

does not vary much based on how e-prescribing systems classify the severity of

the potential drug interaction.

Alert type Drug-safety alerts Overridden

High severity 143,943 89.6%

Moderate

severity67,973 92.7%

Low severity 17,747 92.9%

The kit we operate

is unpredictable

Where are we (2010)?

Safety statistics

•>200 assessed systems

releases

•5 years safety records

•Clinical Safety Group

•10 Regional CSOs

•UK IT safety standards

• For supplier

• For Health Organisations

Safety incidents

•Over 500 reported safety

incidents with IT systems

•Under reporting present

•Key dangerous areas

• Data migration

• Prescribing

• Imaging

• Failure of backup

•But NO deaths attributable

We have travelled a long way...

Where we came from

(2004)

• Review by NPSA : critical of lack of systematic

approach to IT safety management

“and other safety industries would”

• Kick started (Sep 2004) formation of Clinical

Safety Management System

• Legal opinion “CfH have a duty of care…”

Safety engineering for clinical

systems

Industry Standards Techniques

Defence Industry Def Stan 0055/56 Safety cases

FMEA

Human Factors

Aerospace DO178B & C Type approval

Hazard assessment

Electronics IEC61508 Safety management

system

There is an existing, proven, scientific body of

knowledge into which we should tap.

A marriage made in heaven?

Induction ceremony for a newly qualified Safety Engineer

In order to deploy safety engineering techniques effectively we “pair”

a safety engineer and a clinician trained in IT risk management.

Both sides need to make cultural adjustments ...

Issues presented by Large Scale

Integrated Health Systems

• We are working with York University (who

have a specialist software safety team under

Dr Tim Kelly) – papers later in 2010

• We are examining the differences between

safety in “closed” engineering systems and

large “open” ehealth systems

• There are some key differences which need

managing otherwise safety is compromised

A common clinical condition

Issues presented by Large Scale

Integrated Health Systems

Some examples :

• Same-functionality on different hardware

• Lack of empirical safety data

• Multiple and complex vendor relationships

• User population with vastly different “training”

levels from “patient” to “consultant”

Our

approach

must

change

with

lessons

learned

Future direction (Macro influences)

Environment :

• EU legislation on medical software

• Ageing population & chronic conditions :

VTE, T2 Diabetes

• Health budget squeezed

= More cost effective safety approaches

but also more safety approaches

Future direction (technology)

Some challenging safety projects :

• VTE risk assessment tool & closed loops

• Cross border exchange of patient alerts

• Telehealth : glucose monitoring

But : How to regulate safety?

Future direction (profession)

Safety engineering in Health Informatics :

• National Occupational Competence

Framework

• Training courses in safety engineering

• Formal role : National Clinical Safety Officer

• UK Council for Health Informatics Professions

Don’t forget…...

• Safety comes with a price – can we afford it?

• What level of IT risk is “tolerable”? “No risk” is

impossible with a large scale health system.

• Can we regulate ehealth using a Medical

Device standard focused on standalone

software?

centrally managed systems (primary use)

Safety management for the development and operations of

centrally managed systems (secondary use)

- Assure/enforce

- Advise/support
