I used to scratch my head asking the same question until I had an enlightening conversation with a close friend of mine who works for a large healthcare consulting company. He led me to the realization that a physician’s agenda is much different than a machine learning practitioner’s agenda, which is much different than a lawmaker’s agenda, which is much different than a hospital administrator’s agenda. In the spirit of full disclosure, I am a medical doctor with a machine learning background, and I use ML on a daily basis to help other healthcare professionals solve problems.
To lay out the problem more concretely, let’s divide the healthcare landscape into 3 broad categories:
Healthcare professionals have several goals:
Machine learning promises to help physicians make near-perfect diagnoses, choose the best medications for their patients, predict readmissions, identify patients at high-risk for poor outcomes, and in general improve patients’ health while minimizing costs. This is happening at a rapid pace despite the many hurdles, which can be overcome by practitioners and consultants who know the legal, technical, and medical obstacles and the best solutions to those obstacles.
In the early infancy of healthcare informatics, before it was even called healthcare informatics, machine learning algorithms such as neural networks and support vector machines were showed off in publications that predicted the likelihood of malignancy or mortality from a disease. One recent publication that illustrates this is Artificial neural networks and prostate cancer-… [Nat Rev Urol. 2013] from a group at the Charite Hospital in Berlin. This is a great paper, and the Charite Hospital has a tradition of strong interdisciplinary work between physicians and computer scientists; I appreciated this quickly while I was rotating there. However, most physicians have never even heard of machine learning, and most ML practitioners don’t understand the realities of practicing medicine.
