本研究目的在探討應用「導尿管移除評估指標」對病人泌尿道感染發生率及住院天數之影響。採隨機分配的實驗性研究設計，於台灣北部2900 床的醫學中心之胸腔重症加護室及呼吸治療加護室，共收案278 位導尿管留置病人。將所有病人隨機分配至實驗組與對照組，實驗組於導尿管留置第7 天，以「導尿管移除評估指標」評估，確定無符合指標即移除導尿管，對照組則未使用「導尿管移除評估表」。結果發現實施「導尿管移除評估指標」後每千置管天數中泌尿道感染危險機率由18.4‰降至14.4‰ (p=.036)，導尿管留置天數由15.8 天縮短至12.3 天(p=.018)；在總住院天數(p=.898)及加護病房天數(p=.244)方面皆未達統計上顯著差異。證實執行「導尿管移除評估指標」能早期移除導尿管，並有效降低泌尿道感染發生率。

The objective of this study was to compare the effectiveness by using guidelines governing theremoval of indwelling catheters on the reduction of catheter-related urinary tract infections (UTIs). This is anopen-labeled, randomized, controlled study. The study sites were two intensive care units (ICUs) at a 2,900-bedmedical center. A total of 278 subjects who underwent Foley catheter insertion were recruited. All patients wererandomized into control group or experimental group, “Foley catheter evaluation sheet” was used forexperimental group to assess the necessity of catheter and whether it was suitable to remove the unnecessarycatheter on the 7th day. Early catheter removal was found to reduce incidence of UTI (p= .036) in theexperimental group. There was a significantly shorter average duration of catheterization in the experimentalgroup (12.3 days vs 15.8 days for the control group; p= .018). There was no significant difference in the totallength of hospital and ICU stay (p> .05). The use of guidelines for determining when to remove indwelledurinary catheters can reduce the risk of UTI, shorten the duration of urinary catheterization.
