Abstract
INTERNIST-I’s use of “partitioning” to group related diagnoses into problem areas
(for competitive consideration and elimination during case analysis) is felt to be
the source of many of its strengths as well as some of its weaknesses. QMR, INTERNIST-I’s
successor program, embodies a homology function which can act as an alternative to
the partitioner for problem area formation. This study undertakes a comparison of
the problem areas generated by the INTERNIST-I partitioning algorithm, the QMR homology
function, and expert clinicians; it finds the correlation to be poor. The authors
then discuss another method of problem area formation which might better mimic a human
clinician and provide an alternative approach in diagnostic computer-aided decision
making.
