醫療疏失的降低與病患安全的維護已成為世界各國醫療照護上的重要議題,尤其在健康照護過程中,要如何運用資訊科技的導入,讓護理人員在認知適合的情況下,得到正確的醫療資訊,作出適當的護理決策,以預防醫療疏失就顯得非常的重要。Vessey(1991)提出認知適合理論(Cognitive Fit Theory),用以瞭解不同的資訊呈現方式和工作任務之間認知適合與否,讓決策者在進行決策時,針對任務型態來決定適當的資訊提供方式,使得資訊系統有更好的績效表現。
雖然,在過去研究曾試著瞭解環境因素對決策者認知適合的影響,但其中並無探討領域知識對決策者之認知適合,主要是因為缺乏專業領域知識的對象作業研究樣本,使得領域知識的差異一直被忽略的研究變數,因而造成此理論在實務應用上,受到相當的限制。而為了瞭解領域知識的有無是否對護理資訊使用者的認知適合影響,本研究採用多準則工作任務,以護理領域知識的決策工作任務,針對領域知識的有無進行實驗研究,用以觀察決策品質與決策時間,驗證領域知識對於認知適合的影響以及領域知識程度差異性對於決策績效的改變。本研究結果發現:1.領域知識的有無對於決策績效的影響有顯著的差異。2.領域知識對於符號性任務在決策時間上有認知適合效果。3.領域知識對於空間任務在決策時間上則無認知適合效果。 As the technology improve, the need for nurses to collect clinical data increase, which make the task the nurses needed to do more complicated. However, information technology could be a helping tool in making a medical decision. Vessey (1991) came up cognitive fit theory (CFT) to provide a mode in better the quality and efficient of decision making.
To extend the applicability of the CFT, to find out whether domain knowledge would influence the users of nursing clinical data, the researcher had designed a decision task in nursing to compare the difference between having domain knowledge and not having domain knowledge two groups. The researcher observed the quality and the time of decision making the subjects had carried out to discover the influence of using CFT and how the domain knowledge differ the result of the decision making.
