| Summary: | 碩士 === 國立臺北護理健康大學 === 護理研究所 === 103 === In the current era of rapidly advancing information technology, information systems are increasingly being adopted in clinical nursing care to improve the quality of nursing care and the efficiency of nursing administration. In this regard, domestic hospitals are increasingly implementing nursing information systems (NISs). Most studies investigating the effectiveness of these systems have evaluated NIS acceptance according to satisfaction among nurses, whereas few studies have focused on their quality and functionality. Therefore, this study investigated the major NIS implementation factors and their capability of predicting the effectiveness of NIS implementation by using the clinical information systems success model.
The triangulation method was employed in this study. A total of 348 nurses were recruited from regional hospitals in two districts of Taipei through purposive sampling. Research data were collected through questionnaires and focus group interviews 3 and 6 months after an NIS was implemented at their hospital. The questionnaire comprised four dimensions: system performance, information quality, social influence, and facilitating conditions. In addition, use dependence, use satisfaction, and net benefits of the NIS were recorded. The nurses’ subjective opinions regarding the NIS implementation process were obtained through focus group interviews.
The results of this study are as follows: (a) The mean scores of various NIS implementation factors, the nurses’ use dependence and use satisfaction, and the net benefits of NIS 6 months after NIS implementation were higher than the mean scores 3 months after the implementation. (b) Various factors of NIS implementation were positively correlated with the nurses’ use dependence and use satisfaction and the net benefits of NIS. (c) The explanatory power of use dependence, use satisfaction, and net benefits in predicting NIS effectiveness was approximately 64.5%–89.4%. The explanatory power of net benefits in predicting NIS effectiveness after 3 and 6 months exceeded 80%. Among all nurses, medical nurses exhibited the highest NIS use satisfaction, whereas elderly and nonmedical nurses exhibited lowest use dependence. In addition, the higher the use dependence and use satisfaction, the higher the net benefits of implementing NIS.
The qualitative results were as follows: the nurses reported that NIS implementation changed their workflow and positively influenced medication administration safety. However, they also reported that the NIS hardware and software require further improvement. This study empirically identified the critical factors that affect the successful implementation of NISs and reported the nurses’ experience of NIS use. The identified factors can predict the success of implementing NISs in the future.
