The literature concerning the diffusion of innovations reveals that it is not surprising that a promising technology is confronting obstacles in its development and implementation. Alternative technologies also often appear that address the same or similar problems. Better information enables physicians to provide medical care that is less expensive and less error prone. The prescription of medications is reduced in number and cost when the prescribing physician knows the current and previous medications of the patient. The ordering of clinical tests is reduced in number and cost, and the ordering of timely retesting is more likely when physicians have before them information about previous testing of their patient. The challenge is in how the portability of the patient card and its ability to be self-contained can enhance medical practice.
有关创新传播的文献表明，一项有前景的技术在其开发和实施过程中面临障碍并不奇怪。替代技术也常常出现，它们解决相同或类似的问题。更好的信息使医生能够提供成本更低、出错几率更小的医疗服务。当开处方的医生了解患者当前和以前服用的药物时，药物处方的数量和成本都会降低。当医生面前有患者以前的检查信息时，临床检查的数量和成本会降低，而且更有可能安排及时的复查。挑战在于患者卡片的便携性及其独立包含信息的能力如何能够改善医疗实践。
