Abstract:
|
Introduction and increased utilization of cancer screening induces remarkable transient effects on cancer incidence and mortality. When the dust settles we are interested in estimating the achieved benefits comparing a steady state after the intervention with the one before the intervention. We propose methodology for addressing this problem. A model of population under screening is built using methods of queuing theory. The disease free stage and the preclinical disease stage represent two series-connected servers. Stationary states of the system before and after the intervention are derived and linked by a regression model with intervention process characteristics as covariates. The methods are applied to Surveillance, Epidemiology and End Results (SEER) data.
