摘要 尼日利亚甚高频监测系统的评估 综合疾病监测和应对框架的实施已 充满了反复出现的限制，最终导致了一个弱化的医疗系统， 达到这些疾病的行动阈值时的应急响应计划。AIDRAN 该项目旨在评价甚高频监测系统的性能(重点是LASSA和 黄热病)在IDSR框架内确定系统中的相关差距，并提供 实际应用，以改进该国的监测实践。 甚高频监视系统评估研究是AIDRAN项目的一个组成部分，一般 其目标是进行高质量的公共卫生研究，重点是流行病学， 传染病和传染病的临床和实验室项目、监测和研究 尼日利亚的其他重要疾病以及其他对当地具有重要意义的公共卫生威胁。这个 VHF监控系统评估是一种混合方法的过程和结果评估 研究设计。评估将采用两个阶段的进程，其中包括初步审查 现有的拉沙热和黄热病流行病学和实验室数据，然后是实地 评估。将采用多阶段抽样的方法在两个城市地区选择12家卫生机构 政府地区(LGA)和两个农村LGA的六个卫生设施，这些地区分布在三个地区 卫生系统和公私营所有制的不同层次。将使用以下方式收集定量数据 结构化电子工具，并使用STATA 15进行分析。关键线人访谈将是 在四个LGA中的每一个都进行了。定性数据将使用MAXQDA 2018进行分析。 这项研究的测量结果将是收集到的关于性能的可信证据 根据对已定义的系统属性的评估，对甚高频监视系统进行评估。适用范围 将提出加强系统属性的建议。

ABSTRACT Evaluating the VHF surveillance system in Nigeria The implementation of the integrated disease surveillance and response (IDSR) framework has been fraught with recurring constraints culminating in a weakened health system with sub-optimal emergency response plan when the action threshold for these diseases are reached. AIDRAN project aims to evaluate the performance of the VHF surveillance system (focus on Lassa and Yellow fever) within the IDSR framework to identify pertinent gaps in the system and provide practical applications to improve surveillance practice in the country. The VHF surveillance system evaluation study is a component of the AIDRAN project, the general objective of which is to conduct high quality public health research with focus on epidemiologic, clinical, and laboratory-based projects, surveillance, and research of infectious diseases and other important diseases as well as other public health threats of local importance in Nigeria. The VHF Surveillance system evaluation is a process and outcome evaluation with a mixed methods study design. The evaluation will adopt a two-stage process which includes a preliminary review of existing Lassa and Yellow fever epidemiological and laboratory data followed by a field evaluation. Multi-stage sampling will be used to select twelve health facilities in two urban Local Government Areas (LGAs) and six health facilities in two rural LGAs stratified across the three tiers of health system and by public-private ownership. Quantitative data will be collected using structured electronic tools and analyzed using STATA 15. A key informant interview will be conducted in each of the four LGAs. Qualitative data will be analyzed using MAXQDA 2018. The measurement outcomes of this study will be credible evidence gathered on the performance of the VHF surveillance system based on assessment of defined system attributes. Applicable recommendations to strengthen the system attributes will be proposed.
