Repositioning of patients with reduced or impaired mobility could lessen pressure ulcers (PU). Automated preventive devices can support nurses, but user acceptance must be determined with valid and reliable tools. This study measured user acceptance of an automatic lateral turning device, using a self-developed questionnaire.
The study included 194 nurses in leadership positions from 75 institutions. A two-page user acceptance questionnaire was designed and tested for internal validity (exploratory factor analysis; EFA) and reliability (Cronbach's-α). A linear regression analysis was used to test the model's theoretical framework.
The overall response rate was 74.9%. The EFA revealed five exploratory factors ("pain/well-being", "PU prevention", "handling", "nurse support", and "obese patient support") from the two outcomes ("general satisfaction" and "can replace manual repositioning"). The adjusted r was 0.607 for "general satisfaction", with the maximum standardized β for "PU prevention" (0.476), "pain/well-being" (β = 0.197) and "handling" (β = 0.145). The adjusted r for "can replace manual positioning" was 0.458. The β for "nurse support" was 0.264, followed by "pain-wellbeing" (β = 0.224) and "obese patient support" (β = 0.218).
The psychometric testing results were satisfactory. Overall user acceptance of the automatic lateral turning device was high. A positive evaluation of the system's functionality, regarding the prevention of PU, is essential for patient and staff satisfaction, as well as user recommendation.
对于行动不便或身体虚弱的患者，调整其体位可以减少压疮（PU）的发生。自动化预防设备可以为护士提供支持，但必须使用有效且可靠的工具来确定用户的接受程度。本研究使用自行开发的问卷来衡量自动侧翻身设备的用户接受度。
该研究共纳入来自 75 家机构的 194 名担任领导职务的护士。设计并测试了一份两页的用户接受度问卷，以进行内部有效性（探索性因素分析；EFA）和可靠性（Cronbach's-α）。线性回归分析用于测试模型的理论框架。
总的回复率为 74.9%。EFA 从两个结果（“总体满意度”和“能否替代手动翻身”）中得出了五个探索性因素，即“疼痛/舒适度”、“PU 预防”、“操作”、“护士支持”和“肥胖患者支持”。“总体满意度”的调整 r 为 0.607，最大标准化β值为“PU 预防”（0.476）、“疼痛/舒适度”（β=0.197）和“操作”（β=0.145）。“能否替代手动翻身”的调整 r 为 0.458。“护士支持”的β值为 0.264，其次是“疼痛-舒适度”（β=0.224）和“肥胖患者支持”（β=0.218）。
心理测量测试结果令人满意。总体而言，护士对自动侧翻身设备的接受度较高。系统在预防 PU 方面的功能得到积极评价，对患者和员工满意度以及用户推荐至关重要。
