Bedside wisdom

We have been  using unfractioned Heparin for long , and its  is better than any other anticoagulants  in ACS . . . 

Our observation shows that Streptokinase has distinct advanatge over Tenektepelase as it works longer duration  . . .

My experience  says Diuretic and beta blockers  are still good as first line therapy for Hypertension  . . .

Mind you , there are infinite  number of such wisdom in every sub specialty of medical field.

However , the typical response from any  modern scientific intellect would be . . .

Stop it . . . Its old  stuff folk  , What does the current data say ?

medical-data-ethics-futility

Common uttering  in scientific forums,

Is there data backing up your  treatment modality ?

Is there sufficient data ?

Come’on , grow up , don’t talk about experience in a scientific forum . . . come out with data man !

No one seem to care the quality of the data . Every one bothers  about the quality of the Author and Journal instead  .  if its X Y Z its ok If its A B C no its not acceptable data.

Probably , Data is most misused word in medical science.

In scientific world,  “unpublished sense” goes straightway to  dustbin ,while we have so many avenues for the  published nonsense to  be celebrated (Still, bulk of guidelines in cardiology is backed up by Level C evidence which means experience  of experts !)

By the way what do we mean by data ?

Its organised collection of genuine scientific information , that’s post processed ,  follow it up with sound inference and faithful questioning and debate that should ultimately end up as  “clinical  application” in patient domain for consumption.(No prizes for guessing , whats happening in real world !)

OMG, give us back that elusive Common sense . . . which  I  think we  lost some time  at the turn of this millennium  !

Wrong or useless data : Who will recall ?

Once applied to patient , these data is  to be scrutinized and monitored . If we find a study conclusion  and reality does not match , we  need to stall the data from adversely  exploding .Every stake holder should have the power to do it. There have been instances a treatment modality got banished in one country is legally permitted in other country knowing fully well the futility.

Final message 

Modern scientific Data* is not God sent. Its  created , synthesised and disseminated in various mind factories. All you require is , backing up with some pioneering journal publication with huge impact factor.It’s not really blasphemy to question things which doesn’t make sense .Unfortunately , wrong data can be tackled only with further data .(There is no other means I guess !)

When does “good common sense”  become hard data and evidence ?

Its the act of publication , so  please guys whenever you  find some contamination  in so-called scientific data  please post here.  To begin with I am registering a new Journal  “Commonsense journal in cardiology”

*Please note, data is not a bad word as this write-up  seem to suggest.Naturally occurring , epidemiological and  observational data about diseases are the foundations for medical science .The issue become murky when few motivated humans play brutal  games at the sensitive  interface between science and truth.

It should be acknowledged , there is a distinct risk  of  this fight against falsehood end up in blocking  true progress  of science . Still , Homo sapiens  are (believed to be !)  intelligent enough to differentiate good from bad , that’s the reason God gave us the sixth sense !

We all know to err is human , but most of us probably won’t agree medical mistakes , (bulk of which happen in the name of practicing state of the art of science ! ) could be the dominant theme in modern medical care !

BMJ exposes this  well known secret with the help of most authentic data from an apex scientific body CDC , Atlanta .

Men are from Mars , and  Women are from Venus  ” . . . Do you agree ?

Many probably witness the much talked  differential behavior among the gender  every day. Its argued , men take more risk in life ( often  senseless !) , some go to the extreme to  suggest  Men are Idiots and decorate them with a  provocative title  MIT (Men Idiot Theory ) (Mcpherson 2011).Risk taking is important in life, but at  what cost ? Does women (Who  are caring by nature )  help themselves  and the society by less risk taking behavior ?

I stumbled upon this rare piece of writing from BMJ which  would demand  in depth analysis  into this gender phenomenon based on  evolutionary biology and genetics.

This article concludes, Yes, men  . . . indeed  tend to take some foolish risks in various life situations that result in potential harm.

Gender difference in medical outcome men are from mars women venus male idiotic theory darwin theory

What is the influence of MIT on medical profession and patient outcome ?

Now , Iam compelled to ask  a hypothetical question .Does women medical professionals take  less aggressive stance and low risk taking behavior  and in the process result in less mortality and morbidity to our patients  ?

I would think the answer to that question  would be in affirmative .I wish  BMJ or anyone  should design a study on this issue.

These two quotes  on practice of medicine are close to my heart , one from Voltaire , a non medical man (a French poet )  and  the other from ,one of the greatest medical professional of our times, William  Osler .

gretest medical quotes william osler voltaire

It is amazing ,how the thinking pattern of a  philosopher  and a true scientific professional living  centuries apart are almost in sync with a great medical reality !

I was recently asked to suggest a topic for debate on STEMI in  a major Indian cardiology conference. I wished , this is what we  should be mulling  over, with a set of  virtual  guest lectures and special invitees from heaven ! Plenary  session : State of the Art  STEMI care             Time :  11.AMSpeaker : Dr Hippocrates Topic : Aren’t  we erring   on either side of the  Noble profession ? Moderator:  Dr. William Osler Chairperson :  Dr .Harvey Cushings, Dr,Sir Thomas Lewis ,Dr Paul Wood , Excerpts : “While , vast number of  our country-men’s  culprit artery doesn’t even get that  mandatory  Aspirin on time . . . an urban rich  man’s  distal non-culprit artery  is decorated with a fancy  bio-vascular scaffold making  that innocuous lesion vulnerable in the process as well !  Aren’t  we erring   on either side  in the  Noble profession ?

A cardiologist  is  a physician who has  trained himself  in a special  way  to deal with any problem of heart.Ironically , it exists only on paper.The field has developed so vast  no one can master everything .There is no such  “Pan or global cardiology expert” .In fact it would be shortly become unethical to try to become one !

Pediatric cardiology  has developed into such a big field , doing a echo in newborn or  infant has become a comprehensive job and  requires  special talent .This unique  and excellent study from Narayana Institute , Bangalore published in the  prestigious Annals of pediatric cardiology   throws up interesting realities about the quality of echo report done by adult cardiologists in children .The error rate  appears  huge and stands at  prohibitive 38%. While many errors were minor , major  were also not insignificant (23%)

pediatric echocardiography by adults cardiologist

With bulk of the pediatric echo  involves  in the critical decision making  process of device closures and interventions the  data required  becomes vital .The commonest cause for  error is probably not due lack of  knowledge and but to due to lack of commitment and  continuous  exposure in doing echocardiograms in  those age group.

While this paper  decently skirts the issue of quality of pediatric echo done in medium sized hospitals without pediatric cardiology service ,I can say the error rates or inadequate reportage could be significant  in such hospitals  with apparently good ranking .

Final.message

Of course ,we have many  adult cardiologist who do  excellent  pediatric work , It looks like , as a general rule  performing pediatric echocardiograms  by non -institutionalized  adult cardiologist  may not be appropriate ! It may be wise for them to avoid doing echocardiogram in small infants with  truly complex disorders (even perceived  complex) till they gain the required expertise and confidence.

I recall an  adverse  issue happened years ago ,  when I had  missed an associated    PAPVC  in ASD that made my surgeon anxious on table .In a country like ours there is no one to audit our work , “our conscience remains the only option” to deliver the best for our patients  especially so, when they are tiny lives in distress.

After thought

Who am I to suggest  who should do echocardiogram ? , after all every cardiologist is licensed  to do that . One simple  suggestion  would be , if  not confident  they can at least mention in their report it is only  preliminary evaluation and need to be followed up with  an expert . I do that whenever its required  and gives me peace of mind as well !

More controversies* to come

Can adult cardiologist do pediatric intervention ?

* Controversy : One of the meaning for this word  is  “It is a thought  process  set into motion , that aids digging up hidden truths ”
