Overview

Understanding patient safety
What have we learned so far?
Teams create safety
So what should we try to communicate in
education and training?
Imperial Academic Health Sciences Centre
Defining patient safety


`The avoidance, prevention and amelioration of
adverse outcomes or injuries stemming from the
process of healthcare’
– Negative or positive
– Reactive or proactive
An Aspiration & Ambition
– One of a number of objectives
– The heart of quality
Consequences of serious adverse events
for patients & families







Death of neonates, children, adults
Loss of womb in young women
Untreated cancer, mastectomy
Blindness
Disability and handicap, children and adults
Chronic pain, scarring, incontinence
Profound effects on all aspects of their lives
Vincent, Young & Phillips, 1994
Impact of mistakes




`I was really shaken. My whole feeling of self worth
and ability was basically profoundly shaken’
`I was appalled and devastated that I had done this to
somebody’
`My great fear was that I had missed something, then
there was a sense of panic’
`It was hard to concentrate on anything else because I
was so worried’ (Christensen, 1992)

Understanding why things go wrong
The safety paradox


Healthcare staff are:
–
Highly trained & motivated
–
Committed to their patients
–
Use sophisticated technology
Errors are common and patients are frequently
harmed
Understanding why things go wrong
Chain of events
 Complexity and contributory factors
 The importance of cumulative minor errors
and deviations
 Tackling safety on many levels

Contributory factors: 7 levels of safety
Patient
 Task
 Individual staff
 Team
 Working conditions
 Organisational
 Government and regulatory

Vincent, Adams, Stanhope 1998
Teams create safety
I Reliability of ward care



(1) How well do you understand the goals of care
for this patient today?
(2) How well do you understand what work needs
to be accomplished to get this patient to the next
level of care?
Less than 10% of nurses or doctors could answer
these questions
Pronovost et al, 2003
The Impact of Daily Goals



Structured and
organised care for each
patient
Reliability – reducing
the gap between what
should be happening
and what is actually
happening
Reduced length of stay
from 2.5 to 1.3 days


Leadership
–
Who is in charge
Discipline and composure
Explicit communication strategies to
ensure calm and organised atmosphere
Handover
Stages in process clearly defined
Ventilation: Anaesthetists
Monitoring: ODA
Drains: Nurses
Anaesthetist has overall responsibility
Defined moment for transfer to intensivist
Comms limited during equipment phase
Order for briefing (Anes; Surg; Discuss;Plan)
No interruptions
Catchpole et al, 2007

III Care bundles & organisational change
Decreasing catheter related bloodstream
infections





Hand washing
Full barrier precautions
during the insertion of
central venous catheters
Cleaning the skin with
chlorhexidine
Avoiding the femoral site
if possible
Removing unnecessary
catheters


Median rate of infection
per 1000 catheter days
decreased from 2.7 at
baseline to 0 at 3 months
Mean rate at baseline
decreased from 7.7 to 1.4
at 16-18 months follow up
Care bundles & organisational change





A focus on systems
Local ownership and engagement
Encouraging local adaptation of the intervention
Creating a collaborative culture
Time and resources
Pronovost et al, 2008
So what should we try to communicate?
Becoming aware


Communication in Emergency Care
– Tracking the process `I just could not believe
we were doing all this’
– Observing the handover `Staggering, jaw
dropping’
Putting on my `second hat’ (Krishna Moorthy)
The essentials of patient safety








The human tragedies
Scale of error and harm
The safety paradox
Reflecting on one’s own environment
The informal nature of many healthcare processes
The many levels of influence and intervention
The potential for simple changes
That they can make a difference
Safety in clinical practice I





I do not undertake any procedure unless I am sure I am
competent in performing it or have adequate supervision.
Senior clinicians say they want juniors to err on the side of
safety yet many younger clinicians fear seeming weak. I
make a point to reminding myself day after day that I want
to be safe first and brave afterwards.
Spending longer with patients explaining and discussing
the risks and benefits of treatment
Being obsessive about hand washing. I am now very aware
of why we are asked to do this and so less irritated about
the time it takes
Having enough humility to recognize when you are
stepping beyond your depth and willingness to ask for help
(Jacklin, Undre, Olsen)
Safety in clinical practice II





Being more vigilant in terms of errors that occur in day to
day practice which I may have missed in the past.
Being willing to address loose ends rather than say this is
not part of my problem.
Involving the patient in their care. For example always
asking the patient which side they thought they were
having the operation.
Being more explicit about my instructions, discussing
everything I think or intend to do to with the patient
At handover always summarising the situation, outlining
the plan and being absolutely clear about what to monitor
and at what point I want to be called
(Jacklin, Undre, Olsen)
