Advances in biomedical engineering enable us to treat increasingly severe conditions. This implies an increased need for regulation and priority setting in healthcare, to ensure appropriate safety cautions and to avoid accelerating expenditures. This interview study investigates the mechanisms behind the adoption and use of medical devices through the subjective experiences of hospital staff working with devices for neonatal intensive care. The adoption was found to be primarily initiated by vendor activities, but professionals preferably sought information about functionality from close colleagues. Full integration of devices was sometimes not achieved, and even though the adopting units had good introduction routines, there was no systematic follow-up of how adopted devices had been integrated in the work practices. Diffusion variations were, however, mainly found for temporarily tested devices and not for permanently available technologies. Three factors were found to be the major explanatory variables of the adoption of medical devices: (1) the subjective expected value of the device, (2) information and learning, and (3) the innovativeness of the adopting unit.
生物医学工程的进步使我们能够治疗日益严重的病症。这意味着医疗保健领域对监管和优先级设定的需求增加，以确保适当的安全防范措施并避免加速支出。这项访谈研究通过从事新生儿重症监护设备工作的医院工作人员的主观体验，调查了医疗设备采用和使用背后的机制。研究发现，采用主要由供应商活动发起，但专业人员更倾向于从亲密同事那里获取有关功能的信息。设备有时无法完全整合，尽管采用单位有良好的引入程序，但对于采用的设备如何融入工作实践并没有系统的跟进。然而，扩散差异主要出现在临时测试的设备上，而不是永久可用的技术上。发现有三个因素是医疗设备采用的主要解释变量：（1）设备的主观预期价值，（2）信息和学习，以及（3）采用单位的创新性。
