Oops! I did it again! Medical Errors.

And on the eighth day, He couldn’t believe what He had just done…
We ought to learn more from our mistakes than from what we would qualify as successes. In fact it’s not a bad idea to carefully maintain a dairy of complications that one encounters in addition to the ubiquitous logbook. Complications, unexpected adverse events, errors in judgment and technique, logically analyzed, anonymised and recorded over the years should be a great personal treasure to any surgeon. When compiled and edited – may be for all.

A good analysis is not a blame-game. There are no accusations, no confessions, no names, no apologies- just cold, logical assessment of the sequence of events that lead to an undesirable event and the actions that could have prevented it at each step, but didn’t.

Medical care review meets [mortality meets] suffer from accusatory overtones, compulsion to pass judgement, ‘us-against-you theatrics’ and hence, the defensive dilution of candid declaration of errors. It serves very little purpose in its present form. What happens is an unnecessary detailed presentation of clinical findings, investigations and procedures, all smoothened out to paint a picture of inevitable, apparently uncontrollable cascade of events leading to death of the patient. And is death the only undesirable outcome? Isn’t morbidity a more living problem? Is anything learned? Nothing is more volatile than memory of the last mortality meet. And a few weeks later - déjà vu!

Sometimes one wonders – may be physicians should have interaction with business management guys – failure analysis, root cause analysis, Ishikawa’s fishbone…The result of any failure analysis should be solid recommendations that do result in change in practice. Not the usual knee jerk response to an event in recent memory that dwarfs better judgement formed over years of clinical practice and trials.

Tons have been written on good techniques. Terabytes of operative videos. But what is transparent (invisible) to the onlooker are the hundreds of possible steps that the expert surgeon hasn’t taken each time, which avoided a future complication. For every ‘!!’ move there are a million ‘??’ moves that would have got you checkmated…

And not for a moment let us think that we have the greatest responsibility. A bus driver taking fifty sleeping passengers on a dark highway or the pilot flying through a thunderstorm has more at stake. He better have a good breakfast and sound sleep.

"Bridge Too Far"

Prof Charles Warlow had come to India to give a talk on pit falls in clinical trials. Errors in journals as reputed as NEJM …

He said he doesn’t encounter neurocysticercosis, or CVTs like we see here. HIV cases are rare out there! He continued …

“You have got 1.1 billion people in India. Every patient you treat should be in a randomized trial which should give you answers that are directly applicable to your population rather than importing data generated in the west.”

- Charles Warlow
Professor of Medical Neurology, Western General Infirmary, Crewe Road, Edinburgh

May be we should have a central body that can coordinate very large multi-institutional clinical trials in India – funding, monitoring and analysis. Because trials done by an individual or an institute are such a waste of time [other than an exercise in systematic fabrication of data.]

Ok. Now let’s take a look at this –

Decompressive Surgery After MCA Stroke Reduces Death, Improves Functional Outcome - Pooled analysis of 3 trials of randomized patients.

Hope too many neurologist don’t read this! Because I’m sure not too many neurosurgeons like the idea.

Do they still keep that stroke ward bed ready or is it NPOW?
May be I’ll ask visiting-Prof Venky!

This way please...


Slick and Black

Sometimes words aren’t enough.
Because it’s a tight neurovascular space out there. And there’s lots and lots of it on the way.
Is it science? Is it art? Or is it plain cold meticulous logic?
Let’s find out!
