This model shows the Pharmaceutical New Drug Pipeline based on drug release, approval and patent expiry. This pipeline is then linked to patients switching from older drugs to newer drugs based on proven indications and marketing (indication creep). Based on work by Mark Heffernan on the Australian Pharmaceutical Benefits Scheme for drug subsidy.Conference paper and Larger ithink model

From Evans RG and Stoddardt GL  1990 paper Soc Sci Med 31(12)1347-63 , also published in a book by Evans, Barer and Marmor, Why are some people healthy and others not?: The determinants of population health. This is a steady state model of IM-424 that ignores deaths and population increase. This is extended in IM-451

This model shows the dynamics of use of a new medical technology based on its scope of use and perceived relative benefit. The technology needs cumulative usage to fix its glitches, and the benefits will be diluted  as the scope of use widens.
