The algorithm is a very useful tool in medical practice. Like any other tool, it has advantages and disadvantages. The wise physician avoids a modality until he has learned how to use it. The same should be true of algorithms. Obtain some computer primers that explain the writing of algorithms. Experiment with algorithms of your own creation. When you reach the level where you can easily write your own algorithms, you are ready to use those written by others, making any modifications necessary to suit your own philosophy and experience.
