When  a doctor is confronted by serious  doubt  ,  what will be the outcome for the patient  ?

Can  doubting  be beneficial for a patient ?  . It seems so ,  according to  EBM which  stresses   about statistical outcome at every turn of events in a  patient who  is critically  ill .

Is  something ,  always  better than  nothing   ?   Our  limbic  system tends to think so .  It  may not be true. But  in  dire situations ,   many  things  (Proven , unproven)  need to  be tried  however doubtful it ‘s  efficacy  may be  .This is  akin to an  emergency in an  airplane. Even here there need to be a logic.

Then ,this question  arises . How do we make  sure ,  we have a  dire situation on hand  ?

This is the key issue ,  in  the  decision making  for the   critically ill patients .  It  needs  experience ,  only experience !  Though the principle of uncertainty  is the fundamental rule in medicine ,   EBM  aims to bring some degree of certainty in medical therapeutics.

Benefits of doubting in coronary care unit.

In  a  sinking patient  with cardiogenic  shock  , try  the maximum treatment . Even if , the patient is  in severe shock  , take him to the  cath lab ,  try  open the coronary artery . Give the benefit of doubt  to him even though the chances of reviving him is less than 10%.

Risk of doubting in Coronary care unit.

A.Elderly STEMI  with SHT,(Arriving late ,  with  an unknown time  window  after an MI ) To thrombolyse or not ?  . There is  no benefit of doubt here.  Do not thrombolyse. Here , apply  the benefit of doubt against thrombolysis .

B. Chest pain with  LBBB (Thought to be new onset LBBB ) don’t ever rush to thrombolyse.  Wait for the enzyme result . Don’t try to thrombolyse your doubt , instead  thrombolyse the  confirmed thrombus !

C. Patient with persistent ST elevation following thrombolysis ,in an  otherwise asymptomatic and stable patient. Don’t  pass on  ” your doubt ” of salvaging   at least  some myocardium  by rescue PCI .Rescue  should be done before death. You can not resuscitate  dead myocytes.

Final message

The concept of   giving  the  benefits of doubt  to the patient   is a widely prevalent practice  in medicine .This concept is alive  and popular , not because it has proved effective, but because of the primitive   human perception and cognition  , namely “Something is better than nothing ” !

Common sense and logic would suggest , whenever  there is  a benefit  for doubting there would be a  equal (  or  even  more ) unmeasured  hazards and risks . This  becomes  especially  true ,  when   a   physician makes  a therapeutic move  based on doubting than on conviction .
