微生物杀幼虫剂可成为病媒综合管理疟疾控制计划的一个有效组成部分，尽管它并不普遍实施。此外，干预活动的质量控制和评价对于评价以社区为基础的杀幼虫干预措施的潜力至关重要。我们进行了一个过程中的评估，在坦桑尼亚农村地区的幼虫源管理干预，当地工作人员被雇用到蚊子繁殖栖息地的目的是长期减少疟疾传播的微生物杀幼虫剂。我们开发了一个逻辑模型来指导过程评估，然后建立量化指标来衡量干预成功。定量分析干预范围，暴露和保真度进行评估杀幼虫剂的应用，并与杀幼虫剂的工作人员进行了审查，以提供定量结果的背景。结果表明，干预是成功的，因为工作人员在80%的确定蚊子繁殖栖息地应用微生物杀幼虫剂。然而，使用的杀幼虫剂剂量足以确保仅在26%的地点消灭幼虫，这不符合干预保真度的标准。我们认为，培训和协议适应不足，环境和资源问题，以及人为错误造成的低杀幼虫剂的应用率。这说明了几个小的、特定于背景的细节如何在干预蓝图和执行之间产生有意义的差异。这些研究结果可能有助于其他幼虫源管理干预措施的设计，证明额外的培训，监督，测量和评价协议的遵守情况的价值。
Microbial larviciding can be an effective component of integrated vector management malaria control schemes, although it is not commonly implemented. Moreover, quality control and evaluation of intervention activities are essential to evaluate the potential of community-based larviciding interventions. We conducted a process evaluation of a larval source management intervention in rural Tanzania where local staff were employed to apply microbial larvicide to mosquito breeding habitats with the aim of long-term reductions in malaria transmission. We developed a logic model to guide the process evaluation and then established quantitative indicators to measure intervention success. Quantitative analysis of intervention reach, exposure, and fidelity was performed to assess larvicide application, and interviews with larviciding staff were reviewed to provide context to quantitative results. Results indicate that the intervention was successful in terms of reach, as staff applied microbial larvicide at 80% of identified mosquito breeding habitats. However, the dosage of larvicide applied was sufficient to ensure larval elimination at only 26% of sites, which does not meet the standard set for intervention fidelity. We propose that insufficient training and protocol adaptation, environment and resource issues, and human error contributed to low larvicide application rates. This demonstrates how several small, context-specific details in sum can result in meaningful differences between intervention blueprint and execution. These findings may serve the design of other larval source management interventions by demonstrating the value of additional training, supervision, and measurement and evaluation of protocol adherence.
