It is believed (assumed ?), medical science is propelled by constant quest for knowledge and improvement in basic and clinical science that eventually would transform into better patient care and favorably impact global health standards. We know the field of medicine is growing in an unimaginable pace.It’s obvious any growth if uncontrolled or not properly guided is at risk of deviation from the main goal and ultimately turn malignant and destroy the system which it’s supposed to guard.
How many times we realise the current treatment we administer would soon become obsolete and even become dangerous ? What is the point in replacing treatment A by B , and then B is pulled over by C or D and suddenly finding A is better than either C or D (and still we hesitate to fall back on A because its an oldie!)
Still ,this is what we call as practicing ” State of the art medicine” How about a person who defies state of the art , and able to fore- see the futility which is threatening to be the norm in modern medicine. Then,who is really Ignorant ?
I stumbled upon this wonderful writing on this issue by ex BMJ editor by Richard Smith. Mind you , this was published way back in 1992, when the boom of futile ” Human Health shopping” was just about to explode !

Post-amble
Don’t get confused .Noble professionals are licensed to practice with whatever is published as science as long as their intentions are deemed to be genuine .Harm arising out of practicing what’s considered best as on today is acceptable in the court of law.
Meanwhile , its a tragic truth, If you do not follow the herd , you are at risk of being punished even for goodness committed by you. Wisdom and conscience can never win a legal battle ! If you have the courage try practice them !
