Learning Objective #1: describe the relationship between the nurses perceived EOU and the enhancement of job performance with nursesí behavioral intention on the PDA triage support system.
Learning Objective #2: identify the relationships between the interface design, EOU, perceived practical values of contents, perceived U, and nursesí behavioral intention on the PDA system.

Objective
The purpose of this study were to evaluate the nurses of the Emergency Department on their acceptance of expert-based PDA triage support system in order to plan the future use of PDA-based information systems.
Method
This study used the Technology Acceptance Model, which relies on the perceived “easiness of use (EOU)” and “usefulness (U)” factors, to evaluate the nurses’ perceived value and willingness of using the systems.  The PDA triage support systems were developed in the period of June 2003 to May 2004 and five stages of intensive training courses using the systems were held for all 72 emergency nurses at a medical center.  An expert-validated questionnaire was used for the survey on May 2004.  The Cronbach’s alpha scores of the questionnaire ranged from 0.91 to 0.93 and 63 effective copies of the questionnaire were collected.
Results The results showed that there was no statistically significant differences between the nurses’ age, education level, length of working experience, the experience of using PDA and nurses’ behavioral intention on the PDA system.  The significant relationship between the nurses perceived EOU and the enhancement of job performance with nurses’ behavioral intention on the PDA triage support system.  However, there was not enough data to support the relationships between the interface design, EOU, perceived practical values of contents, perceived U, and nurses’ behavioral intention on the PDA system. The results also suggested that the nurses thought that the factor of EOU was more important than U.  The nurses didn’t show interest in the development of expert system and support the triage decision.  The evaluation of the practical use of systems would be the next research topic.
Conclusions

Nurses perceived that the expert-based PDA triage support system enhance their job performance and usefulness, but the practical use of systems need to investigate.
