Clinical waste is a costly and troublesome commodity. Comprising the detritus of medical care, the foremost hazard is the risk of infection from micro-organisms present in these wastes. Infection commonly occurs through penetrating injury, the so-called 'sharps' or 'needlestick' injury, although contamination of non-intact skin or splashes to the eye may transmit infection. Bloodborne viruses (hepatitis B, hepatitis C, human immunodeficiency virus) are the most serious threat, although respiratory, soft tissue and enteric infections are not unknown. The European Hazardous Waste Directive, that harmonizes the categorization and control of wastes, permits downregulation of clinical wastes where the risk of infection may be low. Although strengthened by the requirement for risk assessment in waste classification, UK regulatory guidance promoting classification of some clinical wastes as non-hazardous completely ignores the Centers for Disease Control and Prevention's Universal Precautions for the prevention of transmission of human immunodeficiency virus, hepatitis B virus and other bloodborne pathogens in healthcare settings, which seek to prevent bloodborne virus infection in healthcare workers and others, and the more extensive Standard Precautions that extend these principles to the prevention of healthcare-associated infections and the environmental spread of nosocomial pathogens. By creating a potent cost driver encouraging downregulation of some clinical wastes, UK legislation based on the European Hazardous Waste Directive conflicts with the CDC's Universal/Standard Precautions.
医疗废物是一种成本高昂且麻烦的物品。它包含医疗护理过程中的废弃物,最大的危害是这些废物中存在的微生物导致感染的风险。感染通常通过穿透性损伤,即所谓的“锐器”或“针刺”损伤发生,不过非完整皮肤的污染或溅入眼睛也可能传播感染。血源性病原体(乙型肝炎、丙型肝炎、人类免疫缺陷病毒)是最严重的威胁,尽管呼吸道、软组织和肠道感染也并非罕见。协调废物分类和控制的《欧洲危险废物指令》允许在感染风险可能较低的情况下对医疗废物进行下调分类。尽管在废物分类中通过风险评估的要求得到了加强,但英国促进将一些医疗废物分类为非危险废物的监管指南完全忽视了美国疾病控制与预防中心针对医疗环境中预防人类免疫缺陷病毒、乙型肝炎病毒和其他血源性病原体传播的通用预防措施,这些措施旨在预防医护人员和其他人感染血源性病原体,以及将这些原则扩展到预防医疗相关感染和医院病原体在环境中传播的更广泛的标准预防措施。基于《欧洲危险废物指令》的英国立法通过创造一个促使下调一些医疗废物分类的强大成本驱动因素,与美国疾病控制与预防中心的通用/标准预防措施相冲突。
