As occupants in a hospital, patients are susceptible to air contaminants that can include biological agents dispersed throughout the premise. An exposed patient can become ill and require medical intervention. A consideration for patients is that they may have become environmentally sensitive and require placement in an environment that does not compromise their health. Unfortunately, the hospital environment often contains more biological substances than can be expected in an office or home environment. When a hospital also experiences water intrusion such as flooding or water leaks, resulting mold growth can seriously compromise the health of patients and others such as nursing staff and physicians (Burge, Indoor Air and Infectious Disease. Occupational Medicine: State of the Art Reviews, 1980; Lutz et al., Clinical Infectious Diseases 37: 786-793, 2003). Micro-organism growth can propagate if the water is not addressed quickly and effectively. Immunocompromised patients are particularly at risk when subjected to fungal infection such that the US Center for Disease Control issued guideline for building mold in health care facilities (Centers for Disease and Control [CDC], Centers for Disease and Control: Questions and Answers on Stachybotrys chartarum and Other Molds, 2000). This paper is based on mold remediation of one portion of a hospital unit due to water from construction activity and inadequate maintenance, resulting in mold growth. A large proportion of the hospital staff, primarily nurses in the dialysis unit, exhibited health symptoms consistent with mold exposure. Unfortunately, the hospital administrators did not consider the mold risk to be serious and refused an independent consultant retained by the nurse's union to examine the premise (Canadian Broadcasting Corporation [CBC], Nurses file complaints over mold at Foothills. Canadian Broadcasting Corporation, 2003). The nurse's union managed to have the premise examined by submitting a court order of detention and inspection and for an interlocutory injunction to allow their consultants to undertake air quality testing. Mold remediation procedures are readily available and are not to be discussed here (Silicato, http://www.nibs.org/BETEC/M6/ 13-Silicato_Mold-Remediation.pdf, 2004). However, the difficulty of determining the qualifications of consultants, contactors and project managers are discussed. It also describes the need and importance of a buffer zone between the occupied areas and the mold abatement containment area.
作为医院的入住者,患者容易受到空气污染物的影响,这些污染物可能包括散布在整个医院的生物制剂。暴露的患者可能会生病并需要医疗干预。对于患者来说,一个需要考虑的因素是他们可能已经对环境敏感,需要安置在不会损害其健康的环境中。不幸的是,医院环境中通常含有的生物物质比办公室或家庭环境中预期的要多。当医院还遭遇诸如洪水或漏水等水侵入情况时,由此导致的霉菌生长会严重损害患者以及护理人员和医生等其他人的健康(伯奇,《室内空气与传染病》。《职业医学:最新进展综述》,1980年;卢茨等人,《临床传染病》37: 786 - 793,2003年)。如果水问题得不到迅速有效的解决,微生物生长就会蔓延。免疫功能低下的患者在遭受真菌感染时尤其危险,以至于美国疾病控制中心发布了关于医疗机构中建筑霉菌的指南(疾病控制与预防中心[CDC],《疾病控制与预防中心:关于葡萄穗霉和其他霉菌的问答》,2000年)。本文基于因施工活动中的水和维护不足导致霉菌生长,对医院一个科室的一部分进行霉菌修复的情况。很大一部分医院工作人员,主要是透析科室的护士,出现了与接触霉菌相符的健康症状。不幸的是,医院管理人员认为霉菌风险不严重,并拒绝了护士工会聘请的独立顾问对医院进行检查(加拿大广播公司[CBC],《护士就山麓医院的霉菌问题提出投诉》。加拿大广播公司,2003年)。护士工会通过提交一份拘留和检查的法院命令以及一项中间禁令,得以让其顾问对医院进行检查,以进行空气质量检测。霉菌修复程序很容易获取,在此不做讨论(西利卡托,http://www.nibs.org/BETEC/M6/ 13 - Silicato_Mold - Remediation.pdf,2004年)。然而,文中讨论了确定顾问、承包商和项目经理资质的困难。它还描述了在占用区域和霉菌清除控制区域之间设置缓冲区的必要性和重要性。
