背景：近年台灣攝護腺癌發生率有逐年上昇趨勢，治療造成病人常有勃起功能障礙及生活品質下降情形，為極需關切議題，故引發研究動機。 目的：探討攝護腺癌病人基本屬性、疾病特性與生活品質之相關性及勃起功能是否為主要影響因子。 方法：以便利取樣方式在南部某區域醫院收案，共選取200名攝護腺癌病人，測量工具包括基本資料、勃起功能量表、攝護腺特定生活品質量表。使用統計套裝軟體SPSS for Windows 19.0，進行各項資料分析。 結果：攝護腺癌病人平均年齡73.2歲，96.5%個案有勃起功能障礙，勃起功能對攝護腺特定生活品質有顯著影響，年齡、教育程度、癌症分期、勃起功能與攝護腺特定生活品質呈現相關。 結論/實務應用：此研究結果能提供醫療照護團隊瞭解攝護腺癌病人勃起功能對生活品質之影響，健康照護者能提供病人性諮詢平台，進行評估適時轉介專科提供更完善的照護，針對不同攝護腺癌特性需求，提供個別化照護，藉以提昇個案生活品質。

Background: The incidence of prostate cancer has seen a gradual rise in Taiwan in recent years. Prostate-cancer patients typically suffer from symptoms of erectile dysfunction and a lower quality of life. Thus, understanding this issue is critical to providing appropriate nursing care to this population. Purpose: This study explored the relationships among patient demographic data, disease characteristics, and quality of life. Erectile function was used as the independent variable. Methods: Convenience sampling collected data from 200 patients with prostate cancer undergoing treatment at a regional hospital in southern Taiwan. The research instruments used included a basic cancer information datasheet, the International Index of Erectile Function, and the EORTC Quality of Life Group prostate specific 25-item module. Data were analyzed using SPSS 19.0 to test our hypothesis. Results: The mean age of participants was 73.2 years and 96.5% had clinical erectile dysfunction symptoms. Erectile function was used as the independent variable. Age, education level, cancer stage, and erectile function correlated with quality of life. Conclusions / Implications for Practice: The results of this study may help health professionals understand the association between erectile function and quality of life in prostate cancer patients. Healthcare professionals may then focus on providing patients with consultation platforms for sexual problems and make appropriate referrals to specialized departments or hospitals to provide better care. Healthcare professionals should focus on the specific needs of prostate cancer patients and provide individualized healthcare to improve the quality of life of this population.
