Despite the uptake of parasitological testing into policy and practice, appropriate prescription of anti-malarials and artemisinin-based combination therapy (ACT) in accordance with test results is variable. This study describes a National Malaria Control Programme-led capacity building intervention which was implemented in 10 States of Nigeria. Using the experience of Niger State, this study assessed the effect on malaria diagnosis and prescription practices among febrile under-fives in rural health facilities.
The multicomponent capacity building intervention consisted of revised case management manuals; cascade training from national to state level carried out at the local government area (LGA) level; and on the job capacity development through supportive supervision. The evaluation was conducted in 28, principally government-owned, health facilities in two rural LGAs of Niger State, one in which the intervention case management of malaria was implemented and the other acted as a comparison area with no implementation of the intervention. Three outcomes were considered in the context of rapid diagnostic testing (RDT) for malaria which were: the prevalence of RDT testing in febrile children; appropriate treatment of RDT-positive children; and appropriate treatment of RDT-negative children. Outcomes were compared post-intervention between intervention and comparison areas using multivariate logistic regression.
The intervention did not improve appropriate management of under-fives in intervention facilities above that seen for under-fives in comparison facilities. Appropriate treatment with artemisinin-based combinations of RDT-positive and RDT-negative under-fives was equally high in both areas. However, appropriate treatment of RDT-negative children, when defined as receipt of no ACT or any other anti-malarials, was better in comparison areas. In both areas, a small number of RDT-positives were not given ACT, but prescribed an alternative anti-malarial, including artesunate monotherapy. Among RDT-negatives, no under-fives were prescribed artesunate as monotherapy.
In a context of significant stock-outs of both ACT medicines and RDTs, under-fives were not more appropriately managed in intervention than comparison areas. The malaria case management intervention implemented through cascade training reached only approximately half of health workers managing febrile under-fives in this setting. Implementation studies on models of cascade training are needed to define what works in what context.
尽管寄生虫学检测已被纳入政策和实践中,但根据检测结果适当开具抗疟药物和青蒿素类复方疗法(ACT)的情况仍存在差异。本研究描述了尼日利亚国家疟疾控制规划主导的能力建设干预措施,该措施在 10 个州实施。本文利用尼日尔州的经验,评估了该措施对农村卫生机构中发热 5 岁以下儿童疟疾诊断和处方实践的影响。
该多组分能力建设干预措施包括修订后的病例管理手册;在州一级进行的从国家到州一级的级联培训,在地方政府地区(LGA)一级进行;以及通过支持性监督进行在职能力发展。该评估在尼日尔州两个农村 LGA 的 28 个主要由政府拥有的卫生机构中进行,其中一个实施了干预性疟疾病例管理,另一个作为没有实施干预的比较区域。在快速诊断检测(RDT)用于疟疾的背景下,考虑了三个结果:发热儿童中 RDT 检测的流行率;RDT 阳性儿童的适当治疗;以及 RDT 阴性儿童的适当治疗。使用多变量逻辑回归比较干预前后干预和比较区域之间的结果。
该干预措施并没有提高干预设施中五岁以下儿童的适当管理水平,超过了比较设施中五岁以下儿童的管理水平。在两个区域中,RDT 阳性和 RDT 阴性五岁以下儿童接受以青蒿素为基础的联合治疗的比例同样较高。然而,在比较区域中,RDT 阴性儿童接受无 ACT 或任何其他抗疟药物治疗的比例更好。在两个区域中,少数 RDT 阳性儿童未接受 ACT 治疗,而是开了其他抗疟药物,包括青蒿琥酯单药治疗。在 RDT 阴性儿童中,没有儿童开青蒿琥酯单药治疗。
在 ACT 药物和 RDT 均大量缺货的情况下,干预区域中五岁以下儿童的管理情况并未优于比较区域。通过级联培训实施的疟疾病例管理干预措施仅覆盖了该环境中管理发热五岁以下儿童的卫生工作者的大约一半。需要实施关于级联培训模式的实施研究,以确定在何种情况下有效。
