               Learning Procedural Knowledge in Medicine

Historically, machine learning has often been applied to medical data
with reported success. If so, then why do medical doctors so seldom use
the resulting knowledge bases in their ordinary practice? Analysis of
the possible reasons suggests a new induction paradigm that does not
encode learned structures as decision trees or logical rules, but rather
as "clinical algorithms" that are familiar to doctors. The input is not
a matrix in the "instance x attribute" style, but instead health care
records from hospital databases that encode temporal sequences of events
called "episodes of care". We present a three-step methodology for
developing clinical algorithms from such episodes that combines
unsupervised clustering with supervised induction of decision trees. We
have utilized the approach to induce clinical algorithms for the
treatment of chronic hypertension patients with interesting results.
