preventable iatrogenic harm (IOM, 1999)
> 20-30% of hospitalized patients experience harm (Classen et al.
2011)
> 30% of U.S. health care expenditures are unnecessary or
wasted (IOM 2010; ibid. 2012)
> In Dutch hospitals annually 1,735 - 1,960 annual deaths due to
preventable iatrogenic harm
… and about 30,000 patients got serious iatrogenic harm (2.3%).

What do we know about patient safety?

What has aviation learned since Tenerife?
![Page 12: Diffusion of aviation innovations in hospitals€¦ · > In U.S. hospitals 44,000 - 98,000 annual deaths due to preventable iatrogenic harm (IOM, 1999) > 20-30% of hospitalized patients](https://reader034.vdocuments.mx/reader034/viewer/2022052009/601ea53b9ede1f472242bf0d/html5/thumbnails/12.jpg)
• Innovation = ‘an idea, practice or objective perceived as
new by an individual, a group, or an organisation’
• Diffusion = ‘the process in which an innovation is
communicated, through certain channels over time,
among the members of a social system’
Diffusion of innovations (Rogers 1995)

“The modern-day flight attendant is
more like a safety professional,
almost a different profession from
that what it was in the 1950s and
1960s when American stewardesses
were celebrated icons of American
womanhood”

SIA stewardess Ms Ong
Teng Teng (37) was inspired
by the way nurses cared for
her son Lukas when he had
to undergo surgery as a baby
“When I was flying, I was
happy for myself (..) now I am
satisfied when I can nurse a
patient back to health.”

Many possible barriers for ‘right-siting’ (Venketasubramanian et al. 2008)
Patient: emotional attachment to specialist; greater confidence
in specialist; fear that is will be difficult to return, increased
cost if referred back post-discharge; proximity; etc.
Specialist: reduced confidence in non-specialist; income
generated by seeing patients; etc.
Non-specialist: feeling uncomfortable managing ‘complicated’
cases; lack of time; etc.
Health system factors: gap between primary care and hospital
care; reimbursement not aligned with care pathway; lack of
supporting ‘chain’ EMR; etc.

Conclusions: diffusion of innovations
• Methods not copied, but adapted to fit the local context
• ‘Open innovation’ and ‘co-creation’: use industry experts
and collaboration to ‘seduce’ hospital professionals
• Integration of ‘clinical’ – ‘admin’ – ‘research’ perspectives
in professional organisation (‘user system’)
• Systems approach request systems expertise
