研究目的為瞭解護理人員扎傷發生率、扎傷過程及其影響因素。針對某醫學中心病 房中除護理長以外之全體護理人員（1697人）進行問卷調查，問卷回收率95.82%。醫療尖銳 物品致傷發生時間自82年2月16日至5月15日止，以百分比描述和卡方檢定進行各項分析 後，研究結果顯示：(一)三個月調查期間曾有扎傷經驗者高達70.73%。(二)扎傷的可能因素 為：(1)物品設計和材質不良：多數護理人員認為針頭類與玻璃製品是主要扎傷原因。針頭類 常因針頭蓋口太小不易對準、不易套緊或容易脫落而造成扎傷，另扎傷亦常發生在套回針頭 蓋子時；玻璃製品則因品質欠佳，一半以上玻璃製品扎傷者在使用時破碎。(2)個人因素：1/3 以上護理人員認為個人因素為主要影響扎傷事件的發生；年資、職位與扎傷機率有顯著差異 （p＜0.001）；1/3以上扎傷者表示工作忙碌沒有時間處理，一半以上未使用預防裝備，僅 16.30%採單手套回蓋子。(3)他人因素：114人是他人不慎致傷，21%－35%被扎傷者表示他人 未妥善處理用物或放置不當等所致。(4)環境因素：僅少數護理人員表示環境因素是影響扎傷 的因素；服務單位以外科系和急症單位為多；醫療行為是準備針劑扎傷率最高；地點以病患 為中心的環境常見。因此，為預防醫療尖銳物品致傷，護理人員應提高扎傷危險之警覺性、 練習操作技巧、在病患照護環境中避免遺置尖銳物品、適當使用防護設備或措施，以及改良 醫療尖銳物品之品質和設計。

　　　　　The main focus of this study was to gain an understanding of the frequency of such injuries as well as their the circumstances and causes. The questionnaires were distributed to the entire nursing staff of one hospital (excluding the chief nurse), a total of 1697 people. 95.82% of the questionnaires distributed were completed and returned. After analysis, the following results were obtained: 1. 70.73% of respondents reported being injured by sharp objects of medical apparatus during the period from Feb. 16, 1993 to May 5, 1993. 2. Possible causes of injury included: (1)Poor design and/or poor quality of medical apparatus. A majority of respondents believed this was the main cause of injury from hypodermic needles and glass objects, when attempting to replace the cover; (2) Human error on the part of the injured nurse: This factor varied considerably depending on seniority and rank (p＜0.001); More than half of those injured had not taken any kind of protective measures; (3) Human error on someone else part: 21.35% of those injured claimed their injury resulted from someone else misuse of equipment or misplacing apparatus; (4) Environmental factors: A limited number of respondents claimed their injury resulted from inadequate lighting etc. Therefore, suitable safety measures should be taken when using such apparatus. Also, improvements should be made in the design and quality of sharp objects of medical apparatus.
