Errors and ADEs are costlyAdverse Events in USA Hospitals:

80,000 people hospitalised/year

7,000 deaths/year.

50% of these errors definitely or possibly preventable

$22 billion, costs of preventable adverse events

(1999 USA Institute of Medicine Report)

Errors and ADEs are costlyAt least 1.5 million preventable

ADEs occur each year in the US:

Hospital: 380,000-450,000. Ambulatory Care: 530,000 Long-term care: 800,000

Cost of ADE Non-preventable ADE: $2,595 Preventable ADE: $4,685

In Holland (2005): Each year 10,000 people receive wrong medication

and more than 3000 death each year because of errors.

In Australia:Medical error results in as many as 18 000

unnecessary deaths, and more than 50 000 patients become disabled each year.

AU$ 5 Billion (AUS)

Errors and ADEs are costly

Medication Errorsnearly 1 of every 5 doses in the typical hospital and

skilled nursing facility.The percentage of errors rated potentially harmful was

7%, or more than 40 per day in a typical 300-patient facility.

The problem of defective medication administrations systems, although varied, is widespread.

………Patient safety defined as freedom from accidental injury due to medical care…..Institute of Medicine. To Err is Human. Building a safer Health System, Washington, National Academy Press: 1999

An adverse events: harm or injury caused by the management of a patients’ disease or condition by health care professionals rather than by the underlying disease or condition itself……The World Health Profession Alliance

Definitions:

Definitions:Sentinel Event

An unexpected occurrence involving a death or serious physical or psychological injury or risk thereof. Serious injury specifically includes loss of limb or function.

Preventable Adverse EventCould/should not have happened (Error)

Non-Preventable Adverse EventCould not have been predicted or foreseen

Potential Adverse Event“Near miss” or “close call”, could have resulted in an

accident, injury or illness, but did not, either by chance or through timely intervention

Errorthe failure of a planned action to be completed as intendedthe use of a wrong plan to achieve an aim.

Overusein 2001 top 50 medical and surgical procedures numbered 42 million. 7.5 million of these were unnecessary surgical procedures – causing about 40,000 deaths.

UnderuseMuch greater problem than Overuse. Patients failed to receive recommended care about 46% of the time. e.g. hypertension receives 65% of recommended care.

MisuseAbout 11% of the time patients receive care not recommended – leading to harm

• Underestimated by a factor of 20 or greater

• Reports in health care would presumably number in the millions if adverse events, no harm events, and near misses were captured.

Agency for Healthcare Research and Quality, Making Health Care Safer: A Critical Analysis of Patient Safety, July 2001 Donald Holmquest, MD, PhD, JDChief Technology Offices, eMedical Research, Inc. – 3000 medical fatal errors for 1,000,000 people

More Common than We Thought

Richard Smith

“Knowing is not enough; we must apply. Willing is not enough; we must do.”

Wolfgang von Goethe

How to think of error?An individual failing

It will not solve the problem--it will probably in fact make it worse because it fails to address the problem

Doctors will hide errorsMay destroy many doctors inadvertently (the second

victim)A systems failure

This is the starting point for redesigning the system and reducing error

James Reason’s bottom lineFallibility is part of the human condition

We can’t change the human condition

We can change the conditions under which people work

• Historically, mistakes or poor outcomes have been blamed on “dumb doctor,” or “dumb nurse.” The “solution” was the ABP reaction – Accuse, Blame and Punish.

• But inefficiencies and errors mostly can be traced not to one error, but a cascade of poor or poorly executed procedures, policies, technologies and training. A good system will provide a good outcome; a poorly designed one will produce a poor one.

•We need to design health care systems that put safety first (First, do no harm)

Hopkins Medical News, Edward D. Miller, M.D., Fall 2002, Page 56

Good Outcomes, Good Systems

“…adverse events are generally not the result of one thing that went wrong. They result from the combination of a series of latent errors that are built into the system.”

Paul M. Schyve, MD, Vice President, JCAHO In: Reducing Medical Errors, Improving Patient Safety: Taking the Next Step, HealthLeaders Roundtable, June 2001.

A System Problem

SAFETY BARRIERS

Theory of Constraints

Any improvement is a changenot every change is an improvement

but we cannot improve something unless we change it

Goldratt (1990)

any change is a perceived threat to securitythere will always be someone who will look at the

suggested change as a threat

any threat to security gives rise to emotional resistanceyou can rarely overcome emotional resistance with logic

aloneemotional resistance can only be overcome by a stronger

emotionGoldratt (1990)

Any improvement is a change

“Anyone who thinks you can overcome

emotional resistance with logic was probably

never married”

Error prevention Making errors visible Mitigation of harm from errors

“No problem can be solved within the same consciousness which caused it.”

Albert Einstein

“Since modern information tools can do things that the unaided human mind cannot do, when we use such tools we may see a picture of medicine we have not seen before.”
