探討電子病歷查閱系統APP之使用行為意圖及滿意度

A Study of Users' Intention to Use and Satisfaction of Using the Electronic Health Medical Record APP

目的：探討個案醫院導入電子病歷查閱系統APP，使用者對於系統使用之行為意圖與滿意度。方法：以整合型科技接受模式發展結構式問卷，利用LikertScale5分法探討「績效期望」、「努力期望」、「社會影響」構面與「使用意圖」及「使用滿意度」之關係。調查期間自2019年8月5日至8月30日，共計回收197份問卷。提出4項假說，以結構方程式檢定假說模型。結果：性別、職務別、職稱、系統使用年資、科別會影響社會影響構面；年齡、職務別、職稱、服務年資、系統使用年資、科別會影響使用意圖；系統使用年資會影響使用滿意度。「績效期望」、「社會影響」對「使用行為意圖」具有正向影響（β＝1.51、P＜0.01；β＝0.66、P＜0.01）；而「努力期望」對「使用行為意圖」具有負向影響（β＝-1.48、P＜0.01）。「使用行為意圖」對「使用滿意度」具有正向影響（β＝0.75、P＜0.01）。結論：績效期望、努力期望及社會影響皆對使用行為意圖具有顯著影響，其中社會影響對新系統的使用行為意圖及滿意度影響顯著，主因為系統開發及導入期，由副院長、醫務行政室、資訊組及臨床醫療科代表共同組成專案推動小組，善用團隊合作及科室種子代表同儕影響促進系統推行。

Purpose: To explore users' behavioral intention and satisfaction toward the adopting of electronic health medical records. Method: Based on the Unified Theory of Acceptance and Use of Technology (UTAUT), we applied a structured questionnaire with 5 points Likert scale to survey the constructs of ''performance expectancy'', ''effort expectancy'', ''social influence'', ''behav-ioral intention'', and ''use satisfaction''. A total number of 197 questionnaire responses were collected from August 5th to August 30th, 2019 and verified four hypotheses by the struc-tural equation modeling. Result: We found that gender, position, professional title, system usage years, and department would affect the social influence; age, position, title, service experience, system usage years, and department would affect the intention to use; and system usage years would also affect satisfaction to use. The constructs of ''performance expectancy'', ''effort expectancy'', ''social influence'' had positive effects on ''behavioral intention'' (β=1.51, P<0.01; β=-1.48, P<0.01; β=0.66, P<0.01); The construct of ''behavioral intention'' had a positive effect on ''satis-faction to use'' (β=0.75、P<0.01). Conclusion: The constructs of ''performance expectancy'', ''effort expectancy'', and ''social influence'' all have positive effects on ''intention to use''. Among them the construct of social influence is a more significant one on intention to use and satisfaction toward new system. Management leadership takes top down approach to ensure the success of adopting of electronic health medical records APP, uses multi-discipline corporations to increase the efficiency, and department representatives to influence on colleagues on reaching the goal.
