Using Whole Disease Modelling to inform economic recommendations for the detection, diagnosis, treatment and followup of colorectal cancer TappendenPaul BrennanAlan ChilcottJames SquiresHazel 2020 INTRODUCTION Conventional economic evaluation typically involves piecewise comparisons of competing technologies at a single isolated point in a broader care pathway. This study assesses the value of simulating whole disease and treatment pathways to provide a common economic basis for informing resource allocation decisions across an entire disease service.
