慢性阻塞性肺疾病患者生活功能之預測因子

The Predictive Factors of Functional Performance in Patients with Chronic Obstructive Pulmonary Disease

本研究旨在（1）測量影響功能執行之功能潛能變項，包括年齡、疾病嚴重度、呼吸困難、疲憊、運動耐力、負向情緒、自覺健康等，以及（2）探討影響慢性阻塞性肺疾病患者功能執行之主要影響因素及預測因子。採橫斷式研究設計與以方便取樣方式，共計138位慢性阻塞性肺疾病者來自北台灣某醫學中心之門診。以問卷調查法、六分鍾走路距離測試及病歷查閱法來收集資料，並採用LISERAL8.3及SPSS10.0的Windows版套裝軟體來分析資料。本研究結果發現，慢性阻塞性肺病症患者的功能執行呈現中等程度的困難，以心靈活動、運動及娛樂活動方面的困難度最高年齡、呼吸困難程度、疲憊、負情緒等有統計上顯著的負相關，然與病症嚴重度、運動耐力、自覺健康善則有統計上顯著的正相關。運動耐力、負向情緒、走路後呼吸困難程度、其他慢性病數目及年齡等一個變項，可以解釋COPD患者功能執行的變異量達60.9%，其中運動耐力是主要的預測因子。本研究結果可提供臨床醫護理人員照護COPD患者之相關資訊，例如，可從提昇運動耐力、疏導負向情緒等著手改善COPD患者之功能執行。

The purpose of this study was to (1) test the influencing factor of functional performance, including age, disease severity, dyspnea, fatigue, exercise tolerance, negative mood, and health perception and (2) explore the math predictive factors of functional performance in patients with chronic obstructive pulmonary disease (COPD). A cross-sectional research design with a convenience sampling was used iii this study. There 138 subjects were obtained from one of medical teaching hospital in the north of Taiwan. The questionnaire investigation, 6-mintue-walk distance test, and chart review ere used to collect data that was then analyzed by LISERAL8.3 and SPSS 10.0 Window 5 version. The results of this study show most subjects in the middle level of difficult of functional performance, with the highest in spiritual activity, exercise, entertainment. The relationships show negative association between functional status and age, dyspnea, fatigue, negative emotions, but are positive association between functional performance and disease severity, exercise tolerance, health perception There is 60.9% of variance ill functional performance explained by the factors of exercise tolerance, negative mood, after-walking dyspnea, the number of diseases, and age. The math predictive factor is exercise tolerance. The finding of this study may provide the care information for clinical professional staffs, e.g. improving the functional performance of COPD patients from increasing exercise tolerance and soothing negative mode.
