Major medical error studiesHarvard Medical Practice Study (1984)
Reviewed medical charts of 30,121 patients admitted to 51 acute care hospitals in New York state in 1984
In 3.7% an adverse event led to prolonged admission or produced disability at the time of discharge
69% of injuries were caused by errors

Major medical error studies Australian Quality in Healthcare study
(1995) Investigators reviewed the medical records of
14,179 admissions to 28 hospitals in New South Wales and South Australia in 1995.
An adverse event occurred in 16.6% of admissions, resulting in permanent disability in 13.7% of patients and death in 4.9%
51% of adverse events were considered to have been preventable.

Results of medical error
In Australia medical error results in 18,000 unnecessary deaths and more than 50,000 disabled patients per year
In the USA, medical error results in at least 44,000 unnecessary deaths and over 1,000,000 excess injuries per year

Dr Lee Gruner 2004 5
Origins of Clinical Risk Management “Most people view medical mistakes as an
individual provider issue rather than a failure in the process of delivering care in a complex delivery system. When asked about possible solutions to prevent medical mistakes actions rated effective by respondents were “keeping health professionals with bad track records from providing care” and “better training of health professionals”
( To Err is Human, 1999)
![Page 6: Dr Lee Gruner 20041 Background to Clinical Risk Management and Root Cause Analysis Dr Lee Gruner BSc, MBBS, BHA, FRACMA, MBA (Executive) GAICD](https://reader035.vdocuments.mx/reader035/viewer/2022062315/56649d955503460f94a7de9d/html5/thumbnails/6.jpg)
Dr Lee Gruner 2004 6
Developing a systems approach Research into adverse events in the aviation
industry have supported the systems approach
Don Berwick contends the “bad apples” approach is inappropriate: worst mistakes often made by the best people error provoking states of mind are the last and
least manageable in the error sequence
![Page 7: Dr Lee Gruner 20041 Background to Clinical Risk Management and Root Cause Analysis Dr Lee Gruner BSc, MBBS, BHA, FRACMA, MBA (Executive) GAICD](https://reader035.vdocuments.mx/reader035/viewer/2022062315/56649d955503460f94a7de9d/html5/thumbnails/7.jpg)
Dr Lee Gruner 2004 7
Developing a systems approach
A systems approach is based on: same situations lead to the same errors
regardless of who is involved no single best way to prevent error fallibility is part of being human important features are the chain of events,
actions of individuals, conditions of work and contextual issues
blame lies with the system at least 60% of the time
![Page 8: Dr Lee Gruner 20041 Background to Clinical Risk Management and Root Cause Analysis Dr Lee Gruner BSc, MBBS, BHA, FRACMA, MBA (Executive) GAICD](https://reader035.vdocuments.mx/reader035/viewer/2022062315/56649d955503460f94a7de9d/html5/thumbnails/8.jpg)
Dr Lee Gruner 2004 8
Why does medical error rate continue to be so high?
Lack of awareness of the extent of the problem major errors are uncommon and regarded as outliers most errors do not harm the patient
Professional staff have great difficulty in dealing with human error when it does occur powerful emphasis in medicine on perfection error is regarded as a failure of character “you weren't
careful enough” “ you didn’t try hard enough” error = negligence role models enforce concept of infallibility
![Page 9: Dr Lee Gruner 20041 Background to Clinical Risk Management and Root Cause Analysis Dr Lee Gruner BSc, MBBS, BHA, FRACMA, MBA (Executive) GAICD](https://reader035.vdocuments.mx/reader035/viewer/2022062315/56649d955503460f94a7de9d/html5/thumbnails/9.jpg)
Dr Lee Gruner 2004 9
Why does medical error rate continue to be so high?
Learnings are not shared errors covered up mistakes not evaluated learn from mistakes in a vacuum
Realities of medico-legal action incentives against disclosure
![Page 10: Dr Lee Gruner 20041 Background to Clinical Risk Management and Root Cause Analysis Dr Lee Gruner BSc, MBBS, BHA, FRACMA, MBA (Executive) GAICD](https://reader035.vdocuments.mx/reader035/viewer/2022062315/56649d955503460f94a7de9d/html5/thumbnails/10.jpg)
Dr Lee Gruner 2004 10
Standard approaches If professionals were properly trained and
motivated there would be no errors Training and/or punishment will fix the
problem The individual is at fault- “bad apple” theory Underlying causes of error not explored More emphasis on inspection and quality
control
![Page 11: Dr Lee Gruner 20041 Background to Clinical Risk Management and Root Cause Analysis Dr Lee Gruner BSc, MBBS, BHA, FRACMA, MBA (Executive) GAICD](https://reader035.vdocuments.mx/reader035/viewer/2022062315/56649d955503460f94a7de9d/html5/thumbnails/11.jpg)
Dr Lee Gruner 2004 11
Evidence from human factor and psychological research Human performance is classified into:
skill based rule based knowledge based
Errors are classified as: Active failures
Slips Mistakes Violations
Latent failures Provide conditions in which unsafe acts occur, usually
stemming from decisions of those not directly involved in the workplace
![Page 12: Dr Lee Gruner 20041 Background to Clinical Risk Management and Root Cause Analysis Dr Lee Gruner BSc, MBBS, BHA, FRACMA, MBA (Executive) GAICD](https://reader035.vdocuments.mx/reader035/viewer/2022062315/56649d955503460f94a7de9d/html5/thumbnails/12.jpg)
Dr Lee Gruner 2004 12
Evidence from human factor and psychological research
Slips: errors of action due to break in routine when attention is
diverted influenced by sleep loss, drugs, illness,
anxiety
![Page 13: Dr Lee Gruner 20041 Background to Clinical Risk Management and Root Cause Analysis Dr Lee Gruner BSc, MBBS, BHA, FRACMA, MBA (Executive) GAICD](https://reader035.vdocuments.mx/reader035/viewer/2022062315/56649d955503460f94a7de9d/html5/thumbnails/13.jpg)

Example of an error
Car accident while fiddling with the radioAffixing wrong drug label while talking to
someonePicking up the wrong ampoule while in a
hurry

Dr Lee Gruner 2004 14
Evidence from human factor and psychological research
Mistakes rule or knowledge based errors use the wrong rule lack of knowledge or misinterpretation of
the problem bias may play a significant part- paradigm
theory

Dr Lee Gruner 2004 15
Example of a mistakeMethotrexate prescribed for patient
admitted for elective surgery at a dosage of 15 mg per day
Prescribed by a junior doctorActual dose should have been 15 mg per
weekPatient died a week later of neutropaenia

Dr Lee Gruner 2004 16
Evidence from human factor and psychological research
Violations Deviations from safe operating practice
usually associated with motivational problems eg poor morale/ poor riole modelling/ deficient management

Latent errorsThree Mile Island incident 1979Chernobyl 1986 / Bhopal 1984
poor system design implicated operator error only part of the explanation-
proximal cause root causes present in the system for a
long time i.e. accidents waiting to happen
![Page 21: Dr Lee Gruner 20041 Background to Clinical Risk Management and Root Cause Analysis Dr Lee Gruner BSc, MBBS, BHA, FRACMA, MBA (Executive) GAICD](https://reader035.vdocuments.mx/reader035/viewer/2022062315/56649d955503460f94a7de9d/html5/thumbnails/21.jpg)
Dr Lee Gruner 2004 21
Accident Prevention Must focus on:
Root causes- systems errors in design and implementation
don’t develop solutions to the unsafe acts themselves developing methods of error reduction at each stage
of system development design features that correct for human and
mechanical errors and minimise errors simplification, use of constraints, standardisation
![Page 22: Dr Lee Gruner 20041 Background to Clinical Risk Management and Root Cause Analysis Dr Lee Gruner BSc, MBBS, BHA, FRACMA, MBA (Executive) GAICD](https://reader035.vdocuments.mx/reader035/viewer/2022062315/56649d955503460f94a7de9d/html5/thumbnails/22.jpg)

Dr Lee Gruner 2004 23
Discovery of errors
Efficient routine identification of errors as part of normal practice
Routine investigation of all errors that cause injury
Collect relevant data as this will reduce expenses in the longer term

Dr Lee Gruner 2004 24
Error prevention in hospitals Reduce reliance on memory
check lists/ protocols/ decision aids Improve information access
creative ways to provide information where and when needed
Error proofing “forcing functions”
Standardisation Training
How to prevent errors/ problem solving techniques Better supervision of junior staff Safe practice is as important as effective practice

Use of root cause analysisTo uncover latent errors (errors of
system design) underlying an adverse (sentinel) event
Structured, process focused approachAvoids individual blame Identifies and addresses systems and
organisational issues

Dr Lee Gruner 2004 40
Limitations of RCA Impossible to know if the root cause
established by the analysis is the actual cause of the incident
May be tainted by hindsight biasMay be bias relating to prevailing
concerns in the organisation Time consuming and labour intensiveQualitative rather than quantitative
![Page 41: Dr Lee Gruner 20041 Background to Clinical Risk Management and Root Cause Analysis Dr Lee Gruner BSc, MBBS, BHA, FRACMA, MBA (Executive) GAICD](https://reader035.vdocuments.mx/reader035/viewer/2022062315/56649d955503460f94a7de9d/html5/thumbnails/41.jpg)
Dr Lee Gruner 2004 41
Use of RCA Needs to be regular enough for staff to develop
skills Decision to conduct an RCA depends on
organisational leadership Needs to be conducted for all DHS reportable
sentinel events Only one detailed study of regular use of RCA
and its outcomes RCA and follow up of serious drug events over 12
month period led to a 45% decline in ADEs attributed to blame free RCA and changes in policy and process
