背　景泌尿道感染為長照機構常見感染之一，尤其導尿管相關泌尿道感染（catheter-associated urinary tractinfection, CAUTI）是引起機構感染的主因之一。對許多獨立型的長照機構而言，因資源受限而影響了機構內護理人員對相關泌尿道感染防護的認知。
目　的比較有無接受多媒體影音光碟教學及光碟教學介入前後，長照機構護理人員在導尿管相關泌尿道感染知識之改變程度。方　法採雙組前後測之類實驗設計，進行時間為2010年4月至6月，以高雄市24家獨立型養護中心及1家醫院附設護理之家之72位護理人員為對象，依參加機構主管意願分派為實驗組及控制組，37位實驗組接受一個月的多媒體影音光碟教學，35位控制組則無接受光碟教學，兩組人員均接受導尿管相關泌尿道感染知識量表之前測與後測。結　果實驗組與控制組在知識前測得分無顯著差異（p =.18），多媒體影音光碟教學介入後，實驗組與控制組在知識後測有顯著差異（p < .01），以知識前測得分及婚姻、年齡和工作年資當作共變項，發現實驗組在知識後測仍與控制組有顯著差異（p < .01）。結　論多媒體影音光碟教學可增進護理人員在導尿管相關泌尿道感染的知識，透過知識的提升可能會改變護理人員在導尿管相關泌尿道感染的照護行為，而使導尿管相關泌尿道感染發生率降低，故建議長照機構未來可利用多媒體影音光碟教學作為在職教育的策略。

Background: Urinary tract infection (UTI) is one of the most prevalent infections in long-term care facilities.Catheter-associated urinary tract infection (CAUTI) is the major cause of UTI in these facilities. Nurses’ knowledge of CAUTI in many free-standing long-term care facilities is inadequate due to resource limitations.Purpose: This study assessed the effect on CAUTI knowledge of multimedia CD-ROM instruction by comparing the CAUTI knowledge of nurses who received such instruction and those who did not.Methods: Researchers used a quasi-experimental pretest - posttest control group design; This study was conducted from April to June 2010; Data were collected from 72 nurses working in 24 assisted-living facilities and one hospitalaffiliated nursing home in Kaohsiung. Group assignment was based on nursing home administrator choice. The experimental group received one month of multimedia CD-ROM instruction, and the control group received no CD-ROM instruction. Both groups completed a CAUTI knowledge questionnaire prior to and after the intervention.Results: There was no significant pre-test difference in CAUTI knowledge between the two groups (p = .18). Post-test improvement in CAUTI knowledge in the experimental group nurses was significantly larger than in the control group (p< .01). Using pre-test CAUTI knowledge, marriage, age and work experience as covariates, experimental group nurses had significantly better CAUTI knowledge compared to control group nurses at post-test (p < .01).Conclusions: Multimedia CD-ROM instruction can increase CAUTI knowledge in nurses, which may lead to improved nurse CAUTI care behavior and decreased CAUTI incidence. We suggest promoting multimedia CD-ROM teaching as a continuing education strategy in long-term care facilities.
