1. 1. Evidence based management:
Where does it come from?

2. What field is this? “there is a large research-user gap”
“practitioners do not read academic journals”
“the findings of research into what is an effective intervention are not being translated into actual practice”
“academics not practitioners are driving the research agenda”
“the relevance, quality and applicability of research is questionable”
“practice is being driven more by fads and fashions than research”
“many practices are doing more harm than good”

4. How it all started

5. Problem I: too much information
More than 1 million articles in 40,000 medical journals per year (= 1995; now probably more than 2 million). For a specialist to keep up this means reading 25 articles every day (for a GP more than 100!)
Most of the new insights and treatment methods don’t reach the target group

6. Problem I: too much information
HRM: 1,350 articles in 2010 (ABI/INFORM). For an HR manager to keep up this means reading 3 to 4 articles every day (for a ‘general’ manager more than 50!)

Problem II: persistent convictions

8. give them a drug that reduces the number of irregular beats
Problem III: jumping to conclusions
elderly people who have an irregular heartbeat are much more likely to die of coronary disease
give them a drug that reduces the number of irregular beats

9. How 40,000 cardiologists can be wrong
In the early 1980s newly introduced anti-arrhythmic drugs were found to be highly successful at suppressing arrhythmias.
Not until a RCT was performed was it realized that, although these drugs suppressed arrhythmias, they actually increased mortality.
The CAST trial revealed Excess mortality of 56/1000.
By the time the results of this trial were published, at least 100,000 such patients had been taking these drugs.

10. David Sackett
Half of what you learn in medical school will be shown to be either dead wrong or out-of-date within 5 years of your graduation; the trouble is that nobody can tell you which half.
The most important thing to learn is how to learn on your own.
(Remember that your teachers are as full of bullshit as your parents)

16. 4. Evidence based management:
What is it?

17. Definition
Evidence-based management means making decisions about the management of employees, teams or organizations through the conscientious, explicit and judicious use of four sources of information:
1. The best available scientific evidence
2. Organizational facts, metrics and characteristics
3. Stakeholders’ values and concerns
4. Practitioner expertise and judgment

18. Four sources

19. Evidence based decision
“Good managers use both individual managerial expertise and the best available external evidence, and neither alone is enough. Without managerial expertise, practice risks becoming tyrannized by evidence, for even excellent external evidence may be inapplicable to or inappropriate for an individual organization or team. Without current best evidence, practice risks becoming rapidly out of date, to the detriment of organizations and employees.”

20. Individual Managerial Expertise
Evidence based decision
Individual Managerial Expertise
Managerial skills and managerial judgment
Vital for determining whether the evidence applies to an individual organization (division, team) at all and, if so, how

21. What is evidence? Evidence is not the same as ‘proof’ or ‘hard facts’
Evidence can be
- so strong that no one doubts its correctness, or
- so weak that it is hardly convincing at all

22. Don’t confuse Evidence of effect (do!) Evidence of no effect (don’t!)
No evidence of effect (research!)

23. EBMgt is a 5-step approach
Formulate an answerable question (PICOC)
Search for the best available evidence
Critical appraise the quality of the found evidence
Integrate the evidence with managerial expertise and organizational concerns and apply
Monitor and evaluate the results
