摘要
Background:Benefits associated with telemedicine are contingent upon positive user perceptions. Despite this, research on user perceptions of telemedicine remains limited.Introduction:Usability approaches offer a robust way to assess user perceptions, but have rarely been applied in telemedicine. In this study, a usability approach was employed to examine how user perceptions toward a telemedicine system changed over the course of everyday use.Materials and Methods:A telemedicine system was introduced to a hospital in the home service. Ten mobile nurses completed the System Usability Scale (SUS) after initial use, then again after 18 months of everyday use. Results were compared. Analysis included Bangor et al.'s (2009) adjective rating scale.Results:The initial SUS mean was 83 (standard deviation [SD]=7.98), indicating excellent usability. After 18 months, the SUS mean was 64.38, indicating OK usability (SD=14.25, p < 0.05, 95% confidence interval [CI]). Over time, users had lower desire to use the system frequently (p < 0.05, 95% CI), found it more complex (p < 0.05, 95% CI), and perceived greater inconsistency in its design (p < 0.05, 95% CI).Discussion:Considered with existing evidence, our usability findings indicate that a temporary period of positive user perceptions occurs when new telemedicine systems are used for the first few months. This fades with everyday use, with design inconsistency and perceived complexity becoming more noticeable. Although other factors such as user satisfaction and efficiency may also contribute, further studies are needed for confirmation.Conclusions:User perceptions of telemedicine vary with time. To help maximize the benefits and longevity of telemedicine systems, responding to intermittent user appraisal is desirable.
