Quality laboratory services are a requisite to guide rational case management of malaria. Using a pre-tested, standardized assessment tool, we assessed laboratory diagnostic capacity in 69 primary, secondary and tertiary health facilities as well as specialized laboratories in five administrative zones in Oromia Regional State, Ethiopia, during February and March 2009.
There was marked variability in laboratory diagnostic capacity among the facilities assessed. Of 69 facilities surveyed, 53 provided both comprehensive malaria laboratory diagnosis and outpatient treatment services, five provided malaria microscopy services (referring elsewhere for treatment), and 11 primary care health posts provided rapid diagnostic testing and outpatient malaria treatment. The facilities' median catchment population was 39, 562 and 3581 people for secondary/tertiary and primary health facilities, respectively. Depending on facility type, facilities provided services 24 hrs a day, had inpatient capacity, and access to water and electricity. Facilities were staffed by general practitioners, health officers, nurses or health extension workers. Of the 58 facilities providing laboratory services, 24% of the 159 laboratory staff had received malaria microscopy training in the year prior to this survey, and 72% of the facilities had at least one functional electric binocular microscope. Facilities had variable levels of equipment, materials and biosafety procedures necessary for laboratory diagnosis of malaria. The mean monthly number of malaria blood films processed at secondary/tertiary facilities was 225, with a mean monthly 56 confirmed parasitologically. In primary facilities, the mean monthly number of clinical malaria cases seen was 75, of which 57 were tested by rapid diagnostic test (RDTs). None of the surveyed laboratory facilities had formal quality assurance/quality control protocols for either microscopy or RDTs.
This is the first published report on malaria diagnostic capacity in Ethiopia. While our assessment indicated that malaria laboratory diagnosis was available in most facilities surveyed, we observed significant gaps in laboratory services which could significantly impact quality and accessibility of malaria diagnosis, including laboratory infrastructure, equipment, laboratory supplies and human resources.
质量实验室服务是指导疟疾合理病例管理的必要条件。我们使用经过预先测试的标准化评估工具,于 2009 年 2 月至 3 月在埃塞俄比亚奥罗米亚州的五个行政区评估了 69 个初级、二级和三级卫生设施以及专门实验室的实验室诊断能力。
评估的设施之间的实验室诊断能力存在明显差异。在所调查的 69 个设施中,有 53 个提供全面的疟疾实验室诊断和门诊治疗服务,5 个提供疟疾显微镜检查服务(转往其他地方治疗),11 个初级保健卫生所提供快速诊断检测和门诊疟疾治疗。这些设施的中位数集水区人口分别为二级/三级和初级保健设施的 39562 人和 3581 人。根据设施类型,设施提供 24 小时服务,有住院能力,并且可以获得水和电。设施配备全科医生、卫生官员、护士或卫生推广工作者。在提供实验室服务的 58 个设施中,24%的 159 名实验室工作人员在本次调查前一年接受过疟疾显微镜检查培训,72%的设施至少有一台功能正常的双目电镜。设施的设备、材料和生物安全程序水平各不相同,这些程序是疟疾实验室诊断所必需的。二级/三级设施每月处理的疟疾血片数量平均为 225 张,每月有 56 张确认的寄生虫学。在初级设施中,每月平均有 75 例临床疟疾病例,其中 57 例用快速诊断检测(RDT)进行检测。在所调查的实验室设施中,没有一个具有显微镜或 RDT 的正式质量保证/质量控制协议。
这是埃塞俄比亚发表的第一份关于疟疾诊断能力的报告。虽然我们的评估表明,在大多数接受调查的设施中都可以进行疟疾实验室诊断,但我们观察到实验室服务存在显著差距,这可能会严重影响疟疾诊断的质量和可及性,包括实验室基础设施、设备、实验室用品和人力资源。
