2. an established mechanical procedure for solving certain mathematical problems.

al·go·rithm (lg-rm)
n.
A step-by-step protocol, as for management of health care problems.

algorithm
[al′gərith′əm]
1 a step-by-step procedure for the solution to a problem by a computer, using specific mathematic or logical operations. Compare heuristic.
2 an explicit protocol with well-defined rules to be followed in solving a health care problem.

algorithm,
n an explicit protocol with well-defined rules to be followed in solving a complex problem.

algorithm
a set of rules designed to solve a specific problem by proceeding through a series of prearranged, logical steps. Originally referred to purely mathematical problems, now used in a wider sphere, e.g. to solve diagnostic problems. Often depicted in the form of a box and line diagram which sets out the logic of the procedure or program.

diagnostic algorithm
mapping of the logical steps to be taken in eliminating potential diagnoses which do not match clinical signs or pathological findings and arranging possible diagnoses in order of probability.

algorithm
Decision-making A logical set of rules for solving a specific problem, which assumes that all of the data is objective, that there are a finite number of solutions to the problem, and that there are logical steps that must be performed to arrive at each of those solutions NIHspeak A step-by-step procedure for solving a problem; a formula. See Back-propagation, Critical pathway, Genetic algorithm, Risk of ovarian cancer algorithm.

A diagnostic algorithm can theoretically generate 4 different outcomes: true positive, false positive, true negative, and false negative.
To overcome these problems, Vandewoude et al proposed a diagnostic algorithm, partially derived from the European Organisation for the Research and Treatment of Cancer (EORTC) criteria, but designed to deal with the specific conditions of ICU patients.
We discuss the broad differential diagnosis of lesions presenting in this manner, and we suggest a simple diagnostic algorithm.
