This study aims to investigate whether patients' perceptions regarding a Web-based telemedicine service, for instruction and monitoring of an exercise program, change after brief use.
Thirty patients were allocated, matched on gender and age, to a control group (10) or an experimental group (20). After basic training, the experimental group was given a 15 min opportunity to use a Web-based telemedicine service. Patients' perceptions regarding the telemedicine service were measured using a questionnaire, based on the Technology Acceptance Model (TAM). This questionnaire was administered to both the control and experimental group before and after the experimental group's intervention. Both groups were compared with respect to any change in perceptions related to the Web-based telemedicine service.
The experimental group showed a significantly greater change on the TAM constructs perceived usefulness [F(1,27)=3.40, p =0.08] and perceived ease of use [F(1,27)=5.37, p=0.03] than the control group, who showed no statistically significant change of perceptions. Patients within the experimental group became significantly more positive about the usefulness and ease-of-use of the Web-based telemedicine program after a brief period of use.
These findings show that brief use of a Web-based telemedicine service has a significant positive effect on patients' perceptions of this service. Therefore, as patients do not have prior experience with innovative telemedicine services, offering patients a risk-free way to explore and experiment with the service can increase the development of accurate perceptions and user needs. Ultimately, this will increase patients' acceptance of telemedicine. Future studies should investigate the effect of continued usage on patients' perceptions of telemedicine.
本研究旨在探讨患者对基于网络的远程医疗服务（用于指导和监测运动计划）的看法是否会在短暂使用后发生变化。
将 30 名患者按照性别和年龄进行匹配，分为对照组（10 名）和实验组（20 名）。在接受基本培训后，实验组有 15 分钟的机会使用基于网络的远程医疗服务。使用基于技术接受模型（TAM）的问卷来测量患者对远程医疗服务的看法。在实验组干预前后，对对照组和实验组进行问卷调查。比较两组患者对基于网络的远程医疗服务的感知变化。
实验组在感知有用性[TAM 结构，F(1,27)=3.40，p=0.08]和感知易用性[F(1,27)=5.37，p=0.03]方面的变化明显大于对照组，对照组的感知没有统计学上的显著变化。实验组患者在短暂使用基于网络的远程医疗计划后，对该计划的有用性和易用性的看法明显变得更加积极。
这些发现表明，短暂使用基于网络的远程医疗服务对患者对该服务的看法有显著的积极影响。因此，由于患者没有使用创新的远程医疗服务的经验，为患者提供一种无风险的方式来探索和体验服务，可以增加对服务的准确看法和用户需求的开发。最终，这将提高患者对远程医疗的接受程度。未来的研究应该调查持续使用对患者对远程医疗的看法的影响。
