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.
本文考察了自1950年以来广泛传播的五项医院技术的扩散情况：术后恢复室、重症监护病房、呼吸治疗科、诊断性放射性同位素设施以及脑电图仪。回归分析表明，逻辑函数能够很好地描述医院创新技术的扩散情况，就如同它对其他行业创新技术扩散的描述一样；这些技术的扩散速率处于其他行业相关研究确定的范围内；并且在20世纪60年代中期尚未广泛应用的技术的扩散速率随着医疗保险和医疗补助制度的出现而有所增加。
