摘要

The rapid development in the field of wireless local area networks makes mobile healthcare services feasible. Mobile nursing information systems have become an alternative improving hospitals' nursing operations by increasing mobility, immediateness, and accuracy. This survey research aims to examine factors related to nurses' acceptance towards mobile nursing stations by the application of the Technology Acceptance Model (TAM). According to literature review, experience of use is an important factor for acceptance. In order to examine this factor, a quasi-experimental design was applied. A total of 103 nurses were recruited and administered with structured questionnaires. Among them, 51 nurses with experience using mobile nursing-carts were recruited and assigned as the experimental group. A control group matched with those in the experimental group consisted of 52 nurses who don't have such experience. An ”Adjective Differential Scale of Nursing Operations” was developed to examine how nurses rated the traditional nursing operation in contrast to the mobile one, with respect to reliability, easiness, speed, and convenience. On the basis of TAM, the ”Mobile Nursing System Acceptance Scale” was developed and consisted of 4 factors: easiness, usability, attitude, and intention to use. The results showed that all nurses rated the mobile nursing system with a significantly higher degree in speed than the traditional one (F=85.6, p＜0.001). A significant interaction effect was found between the groups (experimental versus control) and the systems (traditional versus mobile) on the ratings of nursing operation system. In contrast to the experimental group, nurses without prior experience over-estimated the benefits brought about by the mobile nursing system, with respect to speed (F=9.2, p＜0.01) and convenience (F=5.9, p＜0.05). With regard to acceptance, the results showed nurses rated significantly higher degree of easiness than those without experiences (t=5.73, p＜0.05). In addition, the path analyses revealed that factors related to ”intention to use” were different between two groups. Usability (total effect=0.78, p＜0.001) played the important part for nurses with experience, while attitude (total effect=0.31, p＜0.05) played the most important part for those without experience. The implications of this model for healthcare information managers will be discussed.
