So, thankfully, the horror has ended. It has been more than nine months since my mind was totally free of the burden of exams, exams which cost me a large amount of time with family and friends and doing things I like.
My friend, who is obviously not from Medicine, asked me before why we are so worried about these exams. She couldn't understand why, when 95% of us pass, we'd let such an exam turn us into stressed out, freaked out studying machines. But she's right! She has a point, and so do we, in actually being paranoid about that fearsome 5% chance. Unfortunately, at that time I was too obtunded from studying to explain to her properly.
Firstly, although there is a 5% (or so) chance, it is a very unpredictable 5% of people who fail. Back in secondary school or junior college, those who fail exams are the jokers who spend all day playing computer games, wasting their lives away. (By fail I mean get below 50%, not fail to get an A grade) In medical school, those who fail are actually people who still study very hard and know a lot and want to pass, but many unforseen circumstances occur:
1. You get very very nasty examiners and you freak out in front of them
2. You get patients who can tell you the wrong things or refuse to tell you things
3. Under pressure, you make up things to say to the examiner and get caught.
4. Sometimes you think you did well but you may have said the wrong things and the stupidest things, not out of ignorance of the art and science of Medicine, but for want of simple common sense. Eg. saying that a patient hasn't been treated correctly by doctors.
And thus these people fail. Of course, it is a mix of student and examiner factors, but it really is quite unpredictable. A significant proportion of these students are actually academically strong.
Secondly, need I not reiterate that the consequences of failing are immense. There is a gigantic psychological blow because you spent almost a year putting yourself through tremendous mental and emotional and physical stress, only to... fail. It is hard trauma to your self esteem. More pragmatically, it means a few thousand more dollars of daddy and mummy's hard earned savings down the drain.
That's why MBBS scares the shit out of final year medical students, despite them having a clear statistical advantage. The zenith of the fear comes during the Surgery long case, where a mere 30 min of clerking decides the course of the long case examination, which if you fail, you fail the ENTIRE exam. There is only one Surgery long case. Comparatively, you get second and third chances during other exams.
Little surprise that, before the Surgery long case, I knew of more than one person who wanted to puke. Another person shared how she cried the day before the exam. Another person told me that the morning after, he woke up in tension. These aforementioned people aren't your average softies. They are athletes and leaders, some of whom the common citizen may fear meeting in a dark alley. Personally I didn't vomit or cry, but I had nightmares and palpitations and an entire butterfly sanctuary in my stomach.
So, to sum it up:
1. There really is a low chance (5-10%) of failing the MBBS
2. But it is very unpredictable who actually fails
3. And the consequences of failing are catastrophic.
4. Hence, people study their asses off for MBBS
And I have been thinking for the past month, that very similar principles apply to defensive medicine:
1. There really is a very low chance of unexpected catastrophic events occuring (eg. a healthy patient electively admitted for surgery who dies of severe infection)
2. But it is very unpredictable when such events occur
3. And the consequences of these events are catastrophic. Patient dies. Family sad. Dr sued. Dr defamed in newspapers.
4. Hence, some doctors practise defensive medicine.
Fear is a strong strong word. Our technology of today has enabled us to conquer many diseases and many natural barriers, and thus our fear of those, but we have not fully conquered the unknown. As such, we fear it so, so badly. Even the narrowest of possibilities have many of us subjugated through fear.
Ok, now I think we should move beyond this vulgar four lettered f- word. To me, it is not just about fear, but also the want of being safe and thorough, which, well, is a cousin of fear.
A few months ago, a senior physician gave us an MCQ quiz. One of the questions were as follows,
as far as I can remember. This 30ish female lawyer with no past medical history came in for a chest infection. On the day of discharge, she complains of leg pain. Do you a) leave it alone or b) do a
Well's score and a doppler ultrasound? (and there were other options too)
So of course the class was pretty much split between a) and b) when our the physician told us that we should actually leave it alone, because according to statistics there is unlikely to be anything wrong with her (Note: the story is as I can best remember and is no substitute for academic or medical advice. Defensive blogging haha)
Later on, my friends and I discussed the case. I was adamant that the Well's score and doppler ultrasound should have been done. I mean, what's wrong with being safe than sorry? My rationale was that although very rare, it only takes 1 in 100000 incidents to ruin someone's life and your career, not 1 in 5 or 10. Most importantly, these investigations wouldn't cost the patient much. Well's score is free of charge and the doppler maybe costs about $10? Surely as a lawyer she can afford it.
On the other hand, I find it morally wrong if you order an unnecessary MRI (which is very expensive) for a patient who has obvious financially difficulties. If you let your fear burden a patient, that is not acceptable.
And also, there was the time my HO, MO and I were caring for this patient and I noticed "increasingly dry skin" on his feet. Time and time again, I wanted to tell my HO but we always spent very little time on this patient so I never did so for many days.
Hey, there's nothing wrong right? Even the HO or MO didn't notice anything. But one fine day, I decided to open my stupid mouth and my HO agreed, "Let's write a derm referral". I wrote a fine letter stating how "Mr XXX has a dry scaly rash affecting intertrigonous areas of the feet, with the likely impression of tinea pedis (ie fungal infection). Kindly review patient and advise on management." Derm came back and stated that PATIENT HAS SCABIES. SCABIES FREAKING SCABIES. He had to be sent to the isolation ward.
Do I feel proud or downright ashamed of myself in such a case?
Now back to the main issue, is defensive medicine "the right thing to do"? Having read many diatribes in the newspapers and the internet, of course the simple answer is that it is wrong. Of course it is easy to say that defensive medicine is wrong.
But I am also of the opinion that having healthy patients die unexpectedly is also not exactly right either. And having doctors defamed in newspapers for such unexpected circumstances is wrong wrong wrong wrong wrong.
What is right and what is wrong?
You can choose to be "right", and not practise what you think is defensive medicine, or choose to study only moderately hard for the MBBS. But if you end up being the lucky one killing a patient, or failing the exam, what can the world do to reverse this disaster other than to have a few human beings weep for you? If I walked on the street and a drunken driver rammed his lorry into me, me being in the right and he being in the wrong does not at all change the fact that I become dead or paralysed.
So perhaps there is a "right and wrong". Unfortunately, in this world today, it seems that this "right and wrong" is a mere fleeting shadow, a passing wind that cannot withstand the indomitable might of "action and consequence". May actual clinical experience give me more wisdom regarding this.
