Somehow the concept of  Evidence based medicine (EBM )never excited me in spite of great strides it has made. Probably the main reason for this is, EBMs origin, quality, and credibility is currently severely compromised. (Though It appears to ooze science 24/7 and make us believe in it too !) Herewith, sharing some of the forbidden thoughts(with lots of pun)  for a (un)successful practice of EBM. This is definitely not meant for young and novice medical professionals. Strictly for the ones who can segregate sense from non (S)

Evidence-based Doubting

                                                 It is now mandatory for all  journals  to declare the  conflict  of interest by the authors  who are involved in medical research .The purpose apparently is to make all transactions or links  between the researchers and their funding agencies transparent .Even major journals  do not go beyond this . Some ensure it , to appear in the first page of  the article.

 What does the the journals tend to  convey to the reader by publishing the conflicts of interest ?

  •  Does it  mean the article in question  may have a bias or indeed have a bias  ?  and readers are warned  hereby !
  •  Do they send across a message  that the  article may not be really a genuine one and the judgement is left to the the consumers of the articles ?

How often a journal article is rejected purely on the basis of  conflicts of interest ?

Most of  journal articles are rejected  for poor methodology, statistical analysis and so forth .We don’t know how often a paper is rejected  due to a conflict issue per se.If this could happen ,bulk  of drug trials would face a torrid time from the editors.

Why , even the leading scientific  journals never indulge in grading the significance of the conflict ?

Here is an example .

The much hyped drug trial on Hypertension “ACCOMPLISH”  was published in the  world’s most prestigious medical journal recently .It  left  it to the readers to  have their  own assessment  on the conflict issue.

  The consequence of not , grading and investigating  about the conflicts could have  serious  global health  implications both financially and academically .

This study was designed, formulated, completed and published  with a single hidden aim of neutralising the land mark trial  of ALLHAT which recommended diuretics as a first line drug in HT.Apparently diuretics are very  cheap  , effective  generic drugs.

 Is it a scientific rule  that  the  latest evidence  ,  should always prevail over the older evidence ?

No. Science can never have such a rule ! The question is how good and genuine is the evidence.
Just because an evidence is current , it does not  attain a scientific sanctity !
