Body substance precautions was the name given to the body substance isolation-based infection control system that was introduced in January 1990 at a Canadian university hospital with 650 acute care beds and 570 long-term care beds. When the body substance precautions system was begun, traditional category-specific isolation was discontinued.
After 2 years, we reviewed the incidence of several types of nosocomial infections and the frequency of isolation of hospital strains of bacteria before and after the introduction of body substance precautions to find out whether this system was as effective as the previous system of infection control.
Most nosocomial infections did not increase. There was another likely cause for the only one that did. For many years, we had isolated patients infected or colonized by hospital bacteria, limiting their spread throughout the institution. Body substance precautions proved equally effective in doing this.
Our results to date therefore indicate that the body substance precautions system was as successful as category-specific isolation used with other standard infection control techniques in maintaining low rates of nosocomial infections and in controlling the dissemination of hospital strains of bacteria in our institution. Body substance precautions provided a satisfactory alternative to universal precautions and traditional isolation categories for the protection of health care workers against the risk of infection by blood-borne viruses.
“身体物质防护措施”是一种基于身体物质隔离的感染控制体系的名称，该体系于1990年1月在加拿大一所拥有650张急性护理床位和570张长期护理床位的大学医院引入。当开始实施身体物质防护措施体系时，传统的按类别隔离措施就停止了。
两年后，我们回顾了几种类型的医院感染的发生率以及在引入身体物质防护措施前后医院细菌菌株的隔离频率，以查明该体系是否与之前的感染控制体系一样有效。
大多数医院感染并未增加。唯一一种有所增加的感染另有可能的原因。多年来，我们一直对感染医院细菌或被其定植的患者进行隔离，以限制细菌在整个机构内传播。事实证明，身体物质防护措施在这方面同样有效。
因此，我们目前的结果表明，在维持较低的医院感染率以及控制医院细菌菌株在我们机构内传播方面，身体物质防护措施体系与其他标准感染控制技术中使用的按类别隔离一样成功。身体物质防护措施为医护人员提供了一种令人满意的替代通用防护措施和传统隔离类别的方法，以防范血源病毒感染风险。
