The diffusion of hospital technologies: some econometric evidence.

This paper examines the diffusion of five hospital technologies that have spread widely since 1950: the postoperative recovery room, the intensive care unit, the respiratory therapy department, diagnostic radioisotope facilities, and electroencephalograph. The regressions show that the logistic function describes the diffusion of hospital innovations as well as it does the diffusion of innovations in other industries, that the rates of diffusion for these technologies fall within the range established by work on other industries, and that the rates for technologies that were not yet widespread in the middle 1960s increased with the advent of Medicare and Medicaid.
