Algorithms in Medicine

I was waiting to pick up Ivy, my better half in her car. I was bored and looking around, saw a medical journal on the seat. Not having anything else to do, I picked up the thick book. I flipped through it and all I could see was lots of fine print text, drawings and images that made no sense to me and more text. I was about to close the book, since I figured I was better off being bored doing nothing, that I spotted the word Algorithm. Being adventurous, I read either side of the word and saw, "A medical algorithm for assessment an treatment of ..."


I was intrigued. I had no clue that medicine used algorithms and not only in their medical instruments and equipment but in the practice of medicine.

On checking I found that not only was it a common practice in medicine, it was a specialized methodology that was becoming increasingly popular.


"
A medical algorithm is any computation, formula, statistical survey, nomogram, or look-up table, useful in healthcare. Medical algorithms include decision tree approaches to healthcare treatment (e.g., if symptoms A, B, and C are evident, then use treatment X) and also less clear-cut tools aimed at reducing or defining uncertainty.

Medical algorithms are part of a broader field which is usually fit under the aims of medical informatics and medical decision-making. Medical decisions occur in several areas of medical activity including medical test selection, diagnosis, therapy and prognosis, and automatic control of medical equipment.


In relation to logic-based and artificial neural network-based clinical decision support system, which are also computer applications to the medical decision-making field, algorithms are less complex in architecture, data structure and user interface. Medical algorithms are not necessarily implemented using digital computers. In fact, many of them can be represented on paper, in the form of diagrams, nomographs, etc.

I was even more surprised to find that a company exists, "Medal", that defines itself as "The Medical Algorithms company" and has over 20,000 (Yes, Twenty Thousand) algorithms for medical practitioners.

And while I was looking at this subject, I came across a related subject, that is even more fascinating. Artificial Intelligence and Medicine.
