臨床護理人員導尿管相關泌尿道感染之知識態度與行為相關性研究

A Study on the Knowledge, Attitudes, and Behaviors of Clinical Nursing Staff Regarding Catheter-related Urinary Tract Infections

導尿管廣泛使用在醫療機構引發之醫療相關泌尿道感染是全球醫療品質的重要議題。依文獻發展結構式量表評估護理人員導尿管相關泌尿道感染的知識、態度及行為，經臨床專家進行內容效度評估，採用內部一致性評估Cronbach’sα進行信度檢定，探索性因素分析進行效度驗證，獨立樣本t檢定、單因子變異數、皮爾森積差進行相關性檢定。知識量表包括護理人員導尿管照護知識8題、照護態度11題和照護行為12題，研究地點為南部三家醫院、對象為執業中工作滿三個月以上的臨床護理師。知識、態度與行為量表的取樣適足性（Kaiser-Meyer-Olkin，KMO）分別為0.60、0.83與0.93；球形檢定（Bartlett test）結果為p值皆< 0.001，支持因素分析結果為適當性。共300位參與者納入研究，知識、態度與行為信度Cronbach’sα分別為0.36，0.73和0.94。護理人員對導尿管相關泌尿道感染知識的平均得分為60.8±17.6分（滿分100分）。結果顯示知識、態度和行為之間呈現顯著相關性，護理人員知識愈佳，態度與行為表現越正向。

Invasive catheter use is widely prevalent in healthcare institutions, and catheter-associated urinary tract infections (CAUTIs) have become a critical issue affecting global healthcare quality. A structured scale was developed based on the literature to assess the knowledge, attitudes, and behaviors of nursing staff regarding CAUTIs. Content validity was evaluated by clinical experts. Reliability of the questionnaire was assessed using the internal consistency metric Cronbach’sα, and an exploratory factor analysis was conducted to assess construct validity. Study variables were evaluated using independent sample t-tests, one-way ANOVA, and Pearson’s correlation coefficients. The final assessment scale included 8 knowledge items, 11 attitudes items, and 12 behaviors items. The study was conducted at three hospitals of a healthcare group in southern Taiwan, and 300 registered nurses working for at least 3 months across the three hospitals were recruited. Kaiser–Meyer–Olkin (KMO) values, an indicator of sampling adequacy, for the knowledge, attitude, and behavior scales were 0.6, 0.8, and 0.9, respectively. The significant sphericity test (Bartlett test) (p < 0.001) supported the appropriateness of the factor analysis. Nurses scored an average of 60.8±17.6 out of 100 for CAUTI-related knowledge. Significant correlations among the three dimensions (knowledge, attitude, and behavior) were found.
