However, these cases were sporadic and mainly occurring during laboratory activities. It was towards the end of the 1940s, that reports of serum hepatitis in health care workers alerted the investigators to the risk of occupational exposures to blood. Subsequent studies confirmed the risk to be significant in the health care setting, and recommendations on the use of precautions to prevent exposure to blood and on vaccination against hepatitis B in health care workers were first issued in 1982. As of today, we are aware of more than 30 pathogens or diseases that have been transmitted through needlestick or cuts, alone or in combination, including agents used in animal models and even tumors. However, the three pathogens that pose the greatest risk to health care workers and are responsible for most documented cases of occupationally acquired bloodborne disease are hepatitis B virus, hepatitis C virus, and human immunodeficiency virus.

14 回函 一、醫療人員安全衛生中心之中文版EPINet針扎監控系統所得資料，可統計醫療院所各項針型之扎傷率，亦可推算全國各項醫療人員針扎及血液體液暴觸之危險性。以一年期間參與通報之15家醫院，總員工數8714位，被靜脈留置針扎傷而通報者共計13件。若以全國醫療人員總數192,611員推算，則全國一年間有287次醫療人員被靜脈留置針扎傷。 二、由於通報率難以逹到百分之一百，以上估計的扎傷率為低估，亦即全國真正扎傷率，應遠高於每年287次。 三、靜脈留置針是直接與血液接觸的醫療器材，均為患者血液污染性針頭，因此其傳染病毒性肝炎、AIDS等經血液傳染疾病之風險高。以國內可經血液傳染疾病盛行率而言，住院患者16.7%有B型肝炎之帶原(其中感染性特強的HBeAg陽性血液1.7%)；且有12.7%之C肝帶原率。因此推算全國每年有超過84位之醫療人員被具傳染性之靜脈留置針扎傷

26 Not every percutaneous injury was reported to the hospital
Under-reporting was 1/2 ~ 4/5 in previous studies We compare reporting and a retrospective survey (12 month recall of injuries) to determine the under-reporting rates

27 Country Japan 4 79-85% Canada 21 60% US Nash 24 42% US-EPINet 33 40%
4th ICOH - HCWs, Montréal, Canada Studies on occupational risk in the world - Workshop Country Percutaneous exposures rate x 100 beds Estimated under-reporting rate Japan 4 79-85% Canada 21 60% US Nash 24 42% US-EPINet 33 40% France 12 50-57% SIROH Spain Taiwan 13 ? 30% 50% 82% However, these results, like the others coming from studies based on surveillance of reported exposures, are biased by underreporting, a major problem which has been extensively studied. Healthcare workers do not report all of the exposures they sustain, mainly because of a low risk perception, difficulties with the reporting system, lack of time and fear of the consequences of a misbehavior. In 1999, during a workshop of the coordinators of the studies on occupational risk in the world, the rates of percutaneous exposure estimated within these studies were compared and discussed. As you can see, these rates varied greatly between the different countries, and also within the same country between the different studies. One of the main variables affecting these rates was underreporting; therefore, also the underreporting rates, estimated through surveys, were included in the analysis. Correcting for underreporting, the exposure rates are definitely higher, and in the different countries, 20 to 55 percutaneous exposures per 100 beds could be sustained every year by healthcare workers. During the same workshop, it was evidenced that among other factors, differences in the average length of hospital stay could account for the variations between these rates. In the US, for example, there is considerable pressure to minimize the length of patients’ hospital stays and to discharge them as quickly as possible. Probably more diagnostic and invasive procedures are performed in a shorter time period in those countries with lower average stays, thus exposing healthcare workers to more sharp medical devices in a given time interval.

34 And, some things “Untold” but hold great Impacts…

35 受針扎護理師 那時候是我幫同事扶病人的腳，可是她可能硬針抽出來的時候不知道我手在那，就直接往我手扎下去。
扎第一刻就是眼淚快掉出來，問學姊，學姊也是很冷的跟你說就針去急診，其實那時候心情真的是很低落，覺得就是因為沒有人要理你。 過了兩三天，我放完假回來，那個病人他檢查出來VDRL(+)又有C肝這樣子，那剛好我又上到那一team，那一交班，學姊她們不敢跟我講，就畫一朵梅花這樣子，那一看就知道，心情就更低落。 學姊又在旁邊開玩笑，以後妳先生阿，如果你被感染梅毒阿，不能怪妳先生怎樣怎樣。就會更害怕。那種，那時候的想法是覺得說那我真的被感染到了怎麼辦？ 因為有allergy的經驗，所以那時候掛急診，醫生建議要打，說那就再做penicillin test，結果是negative，那他說要打。

36 打到第四次之後就開始allergy，那時候我只是覺得頭整個是昏的，眼睛一直冒星星這樣子，沒過多久就倒了，對，就是整個就是allergy shock這樣子。之後她們就把我放在那個ICU裡面，其實那時候又加了ambu，如果我那時候我沒有醒來的話阿，可能endo就插上去了。 她們是說反正我就一路被抬到ICU的床上，ㄏㄟˋ，她們說我好像有一點黑，就cyanosis這樣子，那就開始擠ambu，可是之後我可能就醒了，那醒來可能因為shock的關係，可能血管在收縮吧，就一直chillness這樣子，反正那時候就覺得，糟了如果當下沒醒的話怎麼辦？整個就是快要憂鬱症發生了。 就還蠻擔心自己之後有什麼事情的話，對，因為其實爸爸年紀也大了，那時候是覺得說 (流淚)，如果我今天有什麼事的話，那他們要怎麼辦？那時候是這樣覺得，妳又會看到我爸這樣子，又看到我媽在旁邊就是狂掉眼淚，就是那時候其實還在用氧氣，對，那時候還在用氧氣，那沒什麼力氣，然後看到她們這樣，我會覺得說我怎麼會這麼不孝，我怎麼讓這種事情發生。」
