A cross-sectional study was conducted in Northwestern Ethiopia involving 18 health-care institutes in August 2003 to assess the physical conditions and current laboratory practice, pertaining to handling sputum specimens in the health-care laboratories carrying out sputum smear microscopy. A structured and pre-tested questionnaire was used to collect information. The laboratories had an area of less than 25 m(2). None of them had separate rooms or safety cabinets for sputum smear preparation. Only three laboratories used facemasks. QJ;Decontamination of sputum specimens prior to disposal was reported in only two. Incineration as a means of sputum specimen disposal was used in only six laboratories. The physical conditions of the laboratories were found below the standard set by the International Union Against Tuberculoses and Lung Diseases. A large number of sputum specimens continue to be handled, despite the poor conditions and procedures in all the healthcare laboratories. Laboratory safety standards need to be improved, to minimize the risk of infection. In addition, there is an urgent need for education, training and supervision of the staff involved in sputum microscopy.
2003年8月,在埃塞俄比亚西北部对18家医疗机构开展了一项横断面研究,以评估进行痰涂片显微镜检查的医疗实验室中与处理痰标本相关的物理条件和当前实验室操作情况。采用一份经过结构化设计和预测试的问卷来收集信息。这些实验室面积小于25平方米。其中没有一家有用于痰涂片制备的单独房间或安全柜。只有三家实验室使用口罩。仅两家报告在处理前对痰标本进行了消毒。仅六家实验室采用焚烧作为痰标本的处理方式。发现这些实验室的物理条件低于国际防痨和肺部疾病联盟设定的标准。尽管所有医疗实验室的条件和程序都很差,但仍有大量痰标本在继续处理。需要改进实验室安全标准,以将感染风险降至最低。此外,迫切需要对参与痰显微镜检查的工作人员进行教育、培训和监督。
