title: Diffusion of new technologies in the treatment of the Medicare population. Implications for patient access and program expenditures.
abstract: Patterns of diffusion were analyzed for three pairs of technologies: one of each pair represents a very recent innovation, and the other is more established. Tremendous growth in utilization from 1985-89 was documented, primarily due to more patients obtaining access to the technologies. Nevertheless, disturbing differences in levels of use remain between black and white patients.
