目标：确定使用新医疗保健技术时标准化、短期满意度测量的可靠性，即用户体验可用性指标的 LITE 版本 (UMUX-LITE)。虽然之前的研究已经证明了 UMUX-LITE 的可靠性及其与推荐产品的可能性衡量标准的关系，例如其他领域的净推荐值 (NPS)，但尚未针对医疗保健技术进行此类测试。材料和方法：120 名医疗保健专业人员对处于不同开发阶段的六种护理点产品进行了评估。使用 UMUX-LITE 来收集他们的使用满意度，并使用 NPS 来表明他们推广该产品的意图。推论统计用于：i) 确定 UMUX-LITE 的可靠性，ii) 评估 UMUX-LITE 与 NPS 在产品开发的不同阶段之间的关系。结果：UMUX-LITE 显示出可接受的可靠性 (alpha = 0.7) 以及与 NPS 的强正相关性 (r = 0.455，p < .001)。这与其他应用领域的发现类似。产品开发水平不影响UMUX-LITE得分，而开发阶段是推广意向的显着预测因子（R-2 = 0.49）。讨论和结论：从业者可以单独应用UMUX-LITE，或与NPS结合使用，以补充访谈和“自制”量表，以调查不同开发阶段新产品的质量。这种缩短的规模适合在医疗保健环境中使用，因为忙碌的专业人员只有很少的时间来支持创新。
Objective.: To ascertain the reliability of a standardised, short-scale measure of satisfaction in the use of new healthcare technology i.e., the LITE version of the usability metric for user experience (UMUX-LITE). Whilst previous studies have demonstrated the reliability of UMUX-LITE, and its relationship with measures of likelihood to recommend a product, such as the Net Promoter Score (NPS) in other sectors no such testing has been undertaken with healthcare technology.Materials and methods: Six point-of-care products at different stages of development were assessed by 120 healthcare professionals. UMUX-LITE was used to gather their satisfaction in use, and NPS to declare their intention to promote the product. Inferential statistics were used to: i) ascertain the reliability of UMUX-LITE, and ii) assess the relationship between UMUX-LITE and NPS at different stages of products development.Results: UMUX-LITE showed an acceptable reliability (alpha = 0.7) and a strong positive correlation with NPS (r = 0.455, p < .001). This is similar to findings in other fields of application. The level of product development did not affect the UMUX-LITE scores, while the stage of development was a significant predictor (R-2 = 0.49) of the intention to promote.Discussion and conclusion: Practitioners may apply UMUX-LITE alone, or in combination with the NPS, to complement interview and 'homemade' scales to investigate the quality of new products at different stages of development. This shortened scale is appropriate for use in the context of healthcare in which busy professionals have a minimal amount of time to support innovation.
