Introduction
How good are we doctors at our craft? Can machines beat us in providing better patient care? Surely Medicine is too complex and every patient is different. There is no way an algorithm driven self learning software can do any good for a patient. Or can it?

limits of current methodology in medical research.
Often in medicine, we research treatments or interventions by comparing them to one another. We often choose large number of patients that when divided in 2 groups may look similar to each other. We need large number of patients in hopes of getting valid results. Then we treat both groups differently and tease out what works and what doesn’t work. For example look at the following famous and excellent study that impacted how we practice now.
source
Simply stated one group of very ill patients got nutrition early intravenously and the other group received nutrition started several days later. The results might surprise you but the point I am making is that the application of this knowledge is applied to the general patient population and that is pretty much the best we can do right now. Imagine how much time and data collection is needed to simply refine this just a bit more. Is feeding 2 days into the illness better than starting at 4 days. Is it possible that withholding nutrition for 5 days vs 7 days is much superior? Is it possible that these timelines should be individualized? We are about to find out the answer to these and similar questions sooner than we expect.
Is human capacity limited in the practice of medicine?
Perhaps an impossible question to answer as there are many aspects of skills in varied fields. The correct question may simply be: “how do we get better?’ Let’s look at one example. It is quite routine nowadays to get something called a CT angiogram to look for blood clots that may be present in the lungs. This is termed pulmonary embolism. A dye is pushed into circulation. A very fast CAT scanner rapidly takes images as the dye circulates through the lung blood vessels. The pictures are analyzed by a radiologist to determine whether there is a clot present. A study looked at how well we do with correct diagnosis:

Not surprisingly there were many scans read as positive for pulmonary embolism when none was present. This is an expected finding for reasons that are not relevant here.
What is the rate of cancer misdiagnosis?
One study reported the number to be as high as 28%.
The field of Medicine has been ever improving.
From disease eradication such as small pox, to curing certain cancers and illness such as hepatitis C, advances in medicine have been amazing. Although, many times when we have looked back we have noted the room for improvement.
ENTER ARTIFICIAL INTELLIGENCE.
Prediction of disease.
source
Prediction of disease was studied utilizing AI program named Deep Patient. Results published showed improved prediction of diseases like schizophrenia, cancer and diabetes.
AI reading Imaging studies.
source
This AI program was only fed 1007 X-rays of patients with TB and without TB. Even at this minute learning scale, the program was able to diagnose TB on subsequent X-rays with a 96% accuracy.
AI detecting metastic cancer on microscopic specimens.
source
For now the program was found to be as good or better than Pathologists.
The Future.
Artificial intelligence will not only improve every aspect of Medicine, it will change everything we know. Searching and learning through millions of records, it will be able to see the minutest individual variations and give us predictive models and suggest the best individualized course of therapy. It will see things differently and analyze from a prespective which a human mind cannot achieve.
We will get answers to things for which we did not know a question even existed. I expect a lot of surprises. I do not expect to practice a decade from now in any shape or form that currently constitutes the practice of Medicine. The evolution is here.
source
I wrote some code analyzing drug trial result and got machine-learning algorithm to work on it, and it found some links nobody thought of before, giving whole new perspective to the next trial.
It's in use now, and will get bigger and better in the future, its exiting!
I studied bioengineering with a big emphasis in computer modeling. It is so exciting to see how computers and AI are going to be able to influence our health landscape. I think we can really look forward to more collaborations between tech and medicine in the future. Definitely a good field to get into now!
I study Bioinformatics, both fields are probably going to work together on that, I wish we will take part in the development.
What are the computer modeling uses you work with? my field is more of a data analysis - computing genetic research, Chemoinformatics - trying to model drugs and chemicals, etc.
Noogler that absolutely what’s going to happen. I think simply data input and what should the patient be treated with will always vastly different than what a doctor will prescribe. It will be mind blowingly beautiful. If you can write codes then I have been thinking about this bank.........
Evolution of science and technology births artificial intelligence, it would definitely be helpful in future.
Amazing!!! If AI be made available its going to change a lot. Wow,so AI can predict future sequence from past records and therapy to solve or cure disease?
This is awesome!!!
If it ever happens....
I think it will be here sooner than we think! In the free software imageJ you can already detect spots of a certain criteria (size, intensity, etc) on images, which i would imagine is pretty similar to detecting dark spots on chest xrays. Now it's all a matter of getting diagnostic guidelines updated!
OMG, I had an Ultra-Sound chest check, and spent the whole time thinking how to create a program which will detect any anomaly via image analysis and manipulation.I wish I had time to work on it, or at least get into a company which does that
When you find that company, invest in it.
Let me know when people like you choose a real good company that we should all invest in. How about writing a post on it?
Oh it’s happening now. It is assumed that radiology will be the first field overtaken.
You nailed it.
People fear AI because of the Hollywood Terminator scenario. The truth is AI is going to rapidly advance humanity.
We are seeing incredible breakthroughs by the likes of Watson in the medical field. The future is going to be devices that people have which will scan their bodies and monitor it for ailments before they are felt.
Biology is now intertwined with IT...which means we are going to see rapid advancement in this area. Medicine, in many ways, is still in the dark ages.
Oh my god , I laughed for 1 whole minute when I realized that I may be remembered as the dark ages doctor
I don't know a lot about medicine aside from it appears to need a lot of data crunching, and I think it's one of the fields where AI would be awesome, for pretty much what's in your conclusion ("The Future" section) which is what most people will be seeing :)
Every major institution in medicine has already employed AI. I think IBM ang google will win the major share. Say hello to Dr . Google.
Oh damn and we've been told how many times not to consult Dr Google who seems to turn your headache into a brain tumour? XD
Seriously though that's pretty awesome.
