本研究採回溯性研究的方式進行，利用透析資料庫系統收集資料，經過文獻探討，使用Weka做為資料探勘分析工作平台，將透析病患分為死亡與未死亡兩類，先以集群分析瞭解兩類病人的特性，進而比較兩群的差異，以驗證這些特徵在存活群集是否明顯，研究發現病患若同時具備60歲以上、女性、有糖尿病、血流速度250ml/min、每週三次透析、活動力少於50分、有使用超純透析液等7項屬性特徵及同時具備60歲以上、男性、沒有糖尿病、血流速度250ml/min、每週三次透析、活動力少於70分、有使用超純透析液等7項屬性特徵，此兩集群特徵為最顯著意義的死亡族群特徵，期望藉由此次的分析，提供護理人員日後臨床的照護參考。

We conducted a retrospective study using a dialysis-related database system to collect laboratory reports and the background information of subject patients. The dialysis patients were also divided into two groups, namely survival and non-survival. Cluster analysis was then performed to identify the significant characteristics for each group of patients. The results revealed that the characteristics of non-survival patients fell into either of the sets: (1) aged over 60, female, diabetic, blood flow of 250 ml/min, receiving dialysis 3 times a week, activity score was less than 50, and using ultra pure dialysis; and (2) aged over 60, male, nondiabetic, blood flow of 250 ml/min, receiving dialysis 3 times a week, activity score was less than 70, and using ultra-pure dialysis. This article will hopefully provide nursing personnel with a reference for future clinical care.
