Abstract

BACKGROUND

Change of Kenyan treatment policy for uncomplicated malaria from sulphadoxine-pyrimethamine to artemether-lumefantrine (AL) was accompanied by revised recommendations promoting presumptive malaria diagnosis in young children and, wherever possible, parasitological diagnosis and adherence to test results in older children and adults. Three years after the policy implementation, health workers' adherence to malaria diagnosis and treatment recommendations was evaluated.

METHODS

A national cross-sectional, cluster sample survey was undertaken at public health facilities. Data were collected using quality-of-care assessment methods. Analysis was restricted to facilities with AL in stock. Main outcomes were diagnosis and treatment practices for febrile outpatients stratified by age, availability of diagnostics, use of malaria diagnostic tests, and test result.

RESULTS

The analysis included 1,096 febrile patients (567 aged <5 years and 529 aged ≥5 years) at 88 facilities with malaria diagnostics, and 880 febrile patients (407 aged <5 years and 473 aged ≥5 years) at 71 facilities without malaria diagnostic capacity. At all facilities, 19.8% of young children and 28.7% of patients aged ≥5 years were tested, while at facilities with diagnostics, 33.5% and 53.7% were respectively tested in each age group. Overall, AL was prescribed for 63.6% of children aged <5 years and for 65.0% of patients aged ≥5 years, while amodiaquine or sulphadoxine-pyrimethamine monotherapies were prescribed for only 2.0% of children and 3.9% of older children and adults. In children aged <5 years, AL was prescribed for 74.7% of test positive, 40.4% of test negative and 60.7% of patients without test performed. In patients aged ≥5 years, AL was prescribed for 86.7% of test positive, 32.8% of test negative and 58.0% of patients without test performed. At least one anti-malarial treatment was prescribed for 56.6% of children and 50.4% of patients aged ≥5 years with a negative test result.

CONCLUSIONS

Overall, malaria testing rates were low and, despite different age-specific recommendations, only moderate differences in testing rates between the two age groups were observed at facilities with available diagnostics. In both age groups, AL use prevailed, and prior ineffective anti-malarial treatments were nearly non-existent. The large majority of test positive patients were treated with recommended AL; however, anti-malarial treatments for test negative patients were widespread, with AL being the dominant choice. Recent change of diagnostic policy to universal testing in Kenya is an opportunity to improve upon the quality of malaria case management. This will be, however, dependent upon the delivery of a comprehensive case management package including large scale deployment of diagnostics, good quality of training, post-training follow-up, structured supervisory visits, and more intense monitoring.

摘要

背景

肯尼亚将复杂型疟疾的治疗方案从磺胺多辛-乙胺嘧啶改为青蒿琥酯-咯萘啶(AL),同时修订了建议,提倡在幼儿中进行疑似疟疾诊断,并尽可能在较大儿童和成人中进行寄生虫学诊断和根据检验结果进行治疗。在该政策实施三年后,评估了卫生工作者对疟疾诊断和治疗建议的遵守情况。

方法

在公共卫生机构进行了全国性的横断面、聚类抽样调查。使用医疗质量评估方法收集数据。分析仅限于有 AL 库存的设施。主要结局是根据年龄、诊断方法的可用性、使用疟疾诊断检测以及检测结果,对发热门诊患者的诊断和治疗情况进行分层。

结果

分析纳入了 88 家有疟疾诊断能力的医疗机构中 1096 名发热患者(567 名年龄<5 岁,529 名年龄≥5 岁)和 71 家无疟疾诊断能力的医疗机构中 880 名发热患者(407 名年龄<5 岁,473 名年龄≥5 岁)。所有医疗机构中,19.8%的幼儿和 28.7%的≥5 岁患者接受了检测,而在有诊断能力的医疗机构中,每个年龄组分别有 33.5%和 53.7%的患者接受了检测。总体而言,63.6%的<5 岁儿童和 65.0%的≥5 岁患者使用了 AL 治疗,而只有 2.0%的儿童和 3.9%的较大儿童和成人使用了阿莫地喹或磺胺多辛-乙胺嘧啶单药治疗。在<5 岁的儿童中,AL 被用于 74.7%的阳性检测、40.4%的阴性检测和 60.7%的未检测患者。在≥5 岁的患者中,AL 被用于 86.7%的阳性检测、32.8%的阴性检测和 58.0%的未检测患者。至少有 1 种抗疟药物被开具给了 56.6%的阴性检测的儿童和 50.4%的≥5 岁患者。

结论

总体而言,疟疾检测率较低,尽管有不同的年龄特异性建议,但在有诊断能力的医疗机构中,两个年龄组之间的检测率差异仅为中度。在两个年龄组中,AL 的使用都很普遍,且先前无效的抗疟治疗几乎不存在。绝大多数阳性检测患者都接受了推荐的 AL 治疗;然而,阴性检测患者的抗疟治疗非常普遍,AL 是主要选择。肯尼亚最近将诊断政策改为普遍检测,这是提高疟疾病例管理质量的一个机会。然而,这将取决于提供全面的病例管理方案,包括大规模部署诊断方法、高质量的培训、培训后随访、结构化监督访问以及更密集的监测。
