Doctor as detective new
1. Doctor As Detective
Dr Jitendra Ingole
MD Internal Medicine
Associate Professor, SKNMC & GH, Pune
2. Diagnosis …Art or Science ?
Best answer would be a judicial
combination of both.
History & Clinical examination are
paramount importance.
For they provide foundation for planning
out investigations or treatment.
4. White Coats and finger prints
Isn’t much of a doctor’s work alike to that
of a detective?
5. Current scenario
Routine use of sophisticated diagnostic
tools is killing the art of clinical
reasoning.
Blind faith in technology
Pre determined diagnostic algorithms
6. How to confront the problems posed
by burgeoning number of available
technologies….
7. The need of hour is ……
Harmonic fusion of all investigative
methods of fictional detectives.
Avoid slavish adherence to protocols.
8. What is happening today is……
Burn money to make diagnostic work
up superficial
Losing intellectual pleasure that comes
from careful diagnostic reasoning.
10. Some analogies between detective
and clinical methods
Try to restore status quo undermined by
crime or disease
Thrive on climate of faith in capabilities
of science and base their methods on
interpretation of clues and s/s.
Reach final conclusion by decoding
signs and symptoms often meaning
less to layman.
13. Shared qualities of detectives &
Clinicians
Ability in Observation
Ability in Deduction
Knowledge
Ability to reconstruct psychological &
social profile
Ability to spot inconsistencies
14. Observation & reasoning…..
Three qualities
Deduction
General to particular
Induction
Particular to general
Abduction
Forming an explanatory
hypothesis
Not only presence of evidence but also their absence is important.
15. So, here is the flaw…..
Flawed belief that disease can be
diagnosed accurately from its specific
external signs
16. And Lo Behold……
We are taught similar way from UG
days…. Only to learn hard fact later,
that signs/symptoms may not follow
books.
Overcoming the blind faith is very
important.
18. Knowledge
There comes a time, when for every
addition, there is deletion of previous
knowledge from our memory.
19. So……..
It is important to know what is important
& what’s not.
And do not allow useless to replace
useful knowledge.
20. I have internet connection……hence
I am invincible doctor….because I
have every possible answer in the
world.
21. The Armchair Specialist…?
Having access to knowledge does not
mean that it will be utilised accurately.
Net searches are worth if & only if
clinician conserves his bedside role.
23. A detective says ……
“ I will identify murderer when I fully know
victim. ”
24. A doctor says …..
“ I will identify the disease when I fully
know patient. ”
25. Ability to Recognise Inconsistencies
Normal or low voltage ECG, HOCM
Cardiac Amyloidosis
26. Sherlock Holmes Aphorisms……
You see but you do not observe.
My method is founded upon observation of trifles.
Never trust general impressions, but concentrate on
details.
It is capital mistake to theorise before one has the data.
27. Sherlock Holmes Aphorisms……
There is nothing like first hand evidence.
There is nothing more deceptive than an obvious fact.
The world is full of obvious things which nobody by any
chance observes.
When you have eliminated all impossible, whatever
remain, however improbable, must be the truth.
28. And the punch line is …….
Do not try to twist the facts to suit theories. Rather,
theories should suit the facts.
29. Adherence to protocols and
procedures……
Though guidelines raise average quality
of care, but if applied uncritically and
blindly, can cause pitfalls.
30. Thus the need of hour is…….
Proper and Juridical use of clinical or
treatment guidelines.
32. Clinical method as science and art
of investigation
Mature Clinician
Spot inconsistencies among clinical ,
instrumental and lab exam
Consider not only what is present but also
what is missing.
Capacity to establish links – physical lab.,
instrumental finding.
Simple logical clinical exam has same
value as complex expensive investigation.
34. The lady detective….Mma Ramotswe
Waiting to see doctor for about an hour
outside his consulting room
Makes accurate & intelligent
observations…which then she narrates
to doctor
35. First patient was butcher……
How ?
Lost a finger on his left hand
Scratching his body
36. Second female patient unable to
sleep at night…… How ?
Slept off while waiting
Had to be awakened on her turn
Milk stains on her clothes… must have
been awake due to baby
38. And then, her doctor tells detective not
to eat too much doughnuts…….How ?
Because her weight not decreasing
since last few years.
Sugar in front of her dress which was
spilled from doughnuts.
39. The Message is clear…….
In other words, history taking and
clinical examination should not become
too structured ritual.
40. Think And Act……
It also means to have a clear
systematic approach in mind whether
taking history or doing clinical
examination.
