背景:心肺復甦術可以增加心跳停止病人的存活率，但心肺復甦術被施行的比率很低。已經有研究在探討施行心肺復甦術的意願與阻礙。洗腎患者的照顧者有較高的機會遇到心跳停止的狀況。但是，很少有針對此族群施行心肺復甦術意願與阻礙的研究。
目的:評估接受血液透析洗腎患者的照顧者施行心肺復甦術意願的決定因子與阻礙。
方法:此研究為橫斷式問卷研究法，對象為台南市接受血液透析洗腎患者的照顧家屬。在2012年二月到四月，從台南市58間血液透析院所中，分層後隨機抽取16間院所(包含1家醫學中心、4家區域或地區醫院與11家診所)。然後在所選取的16間院所中，訪問並發放結構式問卷給所有潛在參與者。
結果:共回收844份問卷，回收率90%。受試者平均年齡是47.8歲。70%表示沒有受過心肺復甦術訓練且47%認為接受心肺復甦術的主要阻礙因素是缺乏參加的管道。54%的受試者表示願意施行完整心肺復甦術在所照顧的洗腎患者。多變項回歸分析發現，心肺復甦術訓練是施行心肺復甦術意願的獨立預測因子(訓練超過兩年者勝算比為1.3;兩年內訓練過的勝算比為2.5)。最常見施行人工呼吸的阻礙是害怕傳染性疾病。最常見施行心臟按摩的阻礙在親人身上是害怕做錯而在陌生人身上是害怕法律問題。
結論:接受血液透析洗腎患者的照顧者施行心肺復甦術的意願並不高。心肺復甦術的訓練是施行心肺復甦術的獨立預測因子，但效果會隨時間經過而衰退。

Background: Cardiopulmonary resuscitation (CPR) could improve survival of cardiac arrest victims. But bystander CPR rate remained low. Some articles elevated willingness to perform CPR and barriers. Care-givers of renal failure patient had higher possibility to encounter cardiac arrest situation. However, little was known about willingness to perform CPR and barriers in this group.
Objective: To evaluate the factors associated with the willingness to perform CPR and barriers in care-givers of renal failure patient on dialysis.
Methods: We conducted a cross-sectional questionnaire study on the care-givers of renal failure patient on hemodialysis in Tainan city from February to April 2012. We stratified 58 hemodialysis units and randomly selected 16 units (1 medical center, 4 regional or local hospitals and 11 clinics) in our study. Then we interviewed potential participants with structured questionnaires in selected hemodialysis units.
Results: Complete information was collected from 844 care-givers of renal failure patient on dialysis, with response rate 90%. The mean age of the subjects was 47.8 years old. The majority (70%) of participants did not receive previous CPR training and 47% participants regarded shortage of an access to attend as main barrier of CPR training. 54% participants showed willingness to perform full CPR on the patient he/she cared. Multivariate regression analysis revealed that CPR training was independent predictor of willingness to perform CPR (Odds ratios were 1.3 when trained more than 2 years ago and 2.5 when trained within 2 years). The most common barrier of rescue breathing was fear of infectious disease. The most common barrier of chest compression was fear of doing wrong when victim was a relative but fear of legal consequence when victim was a stranger.
Conclusion: The willingness to perform CPR in care-givers of renal failure patient on dialysis was not high. CPR training was independent predictor of willingness to perform CPR and the effect of training was decreased with time.
