TIMING MEDICAL EXAMS VIA INTENSITY FUNCTIONS
Gianni Parmigiani (Duke University, NC, USA)
Abstract
This lectures presents decision theoretic methods for timing medical
exams. The specific model is motivated by screening ---that is examining
asymptomatic individuals for hidden disease or risk-increasing
conditions. Ideas and strategies may be applied more broadly to problems
in which a stochastic process is monitored over time with a costly and
possibly faulty data collection procedure.
>From a technical viewpoint, I will contrast approaches based on recursive
dynamic techniques to approaches based on modeling the decision space as
a space of functions. I will discuss computational algorithms and, in
simple cases, explicit rules for deciding whether or not an individual of
given age and risk factors should be screened for a disease, and for
deciding when an individual examined today should be examined again.
Methods are illustrated with data on breast cancer screening.
