现在，越来越多的医疗保健是在远离医院的家庭环境中进行的。虽然有越来越多的轶事证据表明，患者和护理人员在家中使用日益复杂的医疗保健设备时遇到了困难，但几乎没有系统的科学研究来量化该领域家庭医疗保健设备可用性的全球性质。研究往往集中在少数设备上，因此很难对家庭护理设备的可用性有一个广泛的了解。本文的目的是描述一种使用系统可用性量表（SUS）的远程可用性评估方法，并使用该指标报告各种医疗保健设备的可用性。共有271名参与者使用SUS选择并评价了他们选择的多达10种家庭医疗保健设备，其可用性评分从0（不可用）到100（高度可用）。参与者在没有实验人员在场的情况下，在自己家中对455个设备进行了评估。可用性评分范围从98（氧气面罩）到59（家用激素检测试剂盒）。对至少有10个评级的设备进行的分析表明，设备对SUS评分的影响是显著的（P<.001），与家中其他常用物品（如微波炉和电话）相比，这些设备的可用性处于低端。使用这种远程方法收集的家庭医疗保健设备的可用性评分的大型数据库将有利于医生，患者和他们的护理人员。
An increasing amount of health care is now performed in a home setting, away from the hospital. While there is growing anecdotal evidence about the difficulty patients and caregivers have using increasingly complex health care devices in the home, there has been little systematic scientific study to quantify the global nature of home health care device usability in the field. Research has tended to focus on a handful of devices, making it difficult to gain a broad view of the usability of home-care devices in general. The objective of this paper is to describe a remote usability assessment method using the System Usability Scale (SUS), and to report on the usability of a broad range of health care devices using this metric. A total of 271 participants selected and rated up to 10 home health care devices of their choice using the SUS, which scores usability from 0 (unusable) to 100 (highly usable). Participants rated a total of 455 devices in their own home without an experimenter present. Usability scores ranged from 98 (oxygen masks) to 59 (home hormone test kits). An analysis conducted on devices that had at least 10 ratings showed that the effect of device on SUS scores was significant (P<.001), and that the usability of these devices was on the low end when compared with other commonly used items in the home, such as microwave ovens and telephones. A large database of usability scores for home health care devices collected using this remote methodology would be beneficial for physicians, patients, and their caregivers.
