GH19-010, Advancing Infectious Disease Research Across Nigeria (AIDRAN)

摘要 评估尼日利亚的甚高频监视系统 实施综合疾病监测和反应框架， 一直充满了反复出现的制约因素，最终导致卫生系统受到削弱， 在达到这些疾病的行动阈值时制定应急计划。AIDRAN 该项目旨在评估甚高频监视系统的性能（重点是拉萨和 黄热病），以确定系统中的相关差距， 实际应用，以改善该国的监测做法。 甚高频监视系统评估研究是AIDRAN项目的一个组成部分， 其目标是进行高质量的公共卫生研究，重点是流行病学， 传染病的临床和实验室项目、监测和研究， 其他重要疾病以及其他对尼日利亚当地重要的公共卫生威胁。的 甚高频监视系统评估是一个过程与结果相结合的评估方法 研究设计.评估将分两个阶段进行，包括初步审查 现有拉沙热和黄热病流行病学和实验室数据， 评价将采用多阶段抽样方法在两个城市的12个卫生设施中进行选择。 政府地区和两个农村地区的六个卫生设施， 卫生系统分层并由公私所有制。定量数据将使用 结构化电子工具，并使用STATA 15进行分析。一个关键的线人访谈将是 在四个地方政府中进行。定性数据将使用MAXQDA 2018进行分析。 本研究的测量结果将是收集到的关于绩效的可信证据 基于对已定义系统属性的评估，适用 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.
