With this in mind, bad outcomes are unavoidable in every field. I have heard that even in ortho, even benign complications can be devastating from the surgeon perspective, to the point where it's almost too much to handle and they seriously consider throwing in the towel. This makes 100% sense to me, because just the thought of being responsible for a patient that you personally cut into, even for a routine case is almost overwhelming, even as a lowly med student. I mean, you put your heart and soul into this, all for the sake of the patient, and something goes wrong? It's like an assault on your identity, almost. I can easily see how it can make someone go nuts. How much more so in a field with a relatively high morbidity and mortality?
This is the other side of the coin. Bad outcomes from elective surgeries are a thousand times worse. If your substrate is a healthy person with a knee issue and something goes wrong, the patient would have been better off if he had never met you, and that's devastating.
Surgery is all about the benefits of surgery outweighing the risks. Knee scopes happen because the potential benefit to quality of life outweighs the small risk of something bad happening. Neurosurgeons are often forced to intervene because the risk of NOT doing surgery becomes too high, i.e. high risk of death or disability due to the natural history of the disease. In cases like that, the benefits are SO great (life-saving) that they outweigh almost any risks of the procedure, which are much higher than an ortho case. That's when bad outcomes happen, and they are mostly unavoidable.
But to your point, the surgeon did not cause the disease or put the patient in the position of having to choose between death and serious risk of disability. Outside of malpractice and gross negligence, bad things happen and sometimes have to happen when the pathology is so dire (e.g. hearing is often sacrificed on one side to completely resect a schwannoma; that's a way worse outcome than the risk of almost any ortho procedure, but most patients sign up for it knowing 100% it will happen). Morbidity is often expected and is easier to accept when the benefits still outweighed the risks and the life was saved.
This is an interesting framework to think about this issue rather than just outcomes. Are you a neurosurgeon?
Even though the "incomes" for orthopedics and neurosurgery are quite different, and that is what in large part explains the "outcomes", it's hard to get around the fact that at the end of the day as a neurosurgeon it seems like you're giving a lot more bad news to families than as an orthopedic surgeon. The highs (curing someone's brain cancer) might be higher, but the lows (take out too much tumor and now the patient is in a coma) are much lower. It seems to me like to be successful as a neurosurgeon you have to be emotionally hardwired in a way to be able to let those high highs get you through those extremely low lows and I'm not sure that will work for me.
I'm a resident. You're absolutely right that we give more bad news. If that's what matters to you and what was motivating this discussion of outcomes, ortho will probably be a better fit. But please, if you're just about to start med school, don't discount your ability to handle it and write off working with sick patients yet.
You do have to be willing to deal with death (and fates worse than death, IMO), but bad outcomes are not all low lows—this goes back to my original point. If the patient came in dying, you saved his life, and now he's hemiplegic, that's a bad outcome for the patient compared to where he was 24 hours ago, but it's a good result because the work was meaningful and made more of a difference than any shoulder scope ever could.
For me, the low lows come with the diagnoses. Scrolling through the MRI of a patient with a headache and finding a GBM is a low low. Seeing a high cervical injury in a teenager in a car crash is a low low. From there, we do what we can to make things better, and that's rewarding. Those two cases are the worst because there's not a whole lot we can do, but most of the time we can make an impact.
