BACKGROUND Malaria surveillance system strengthening is essential in the progress towards malaria elimination. In Nigeria, more attention is being given to this recently as the country is striving towards achieving elimination. However, the surveillance system performance is fraught with challenges including poor data quality with varying magnitude by state. This study evaluated the operation of the Kano State malaria surveillance system and assessed its key attributes. METHODS An observational study design comprising a survey, record review and secondary data analysis, and mixed methods data collection approach were used. Four key stakeholders' and 35 Roll Back Malaria Focal Persons (RBMs) semi-structured interviews on operation of the system and attributes of the surveillance system, were conducted. We analyzed the abstracted 2013-2016 National Health Management Information System web-based malaria datasets. The surveillance system was evaluated using the "2001 United States Centers for Disease Control's updated guidelines for Evaluating Public Health Surveillance Systems". Data were described using means, standard deviation, frequencies and proportions. Chi-squared for linear trends was used. RESULTS Overall, 24 RBMs (68.6%) had ≤ 15-year experience on malaria surveillance, 29 (82.9%) had formal training on malaria surveillance; 32 RBMs (91.4%) reported case definitions were easy-to-use, reporting forms were easy-to-fill and data flow channels were clearly defined. Twenty-seven respondents (69.2%) reported data tools could accommodate changes and all RBMs understood malaria case definitions. All respondents (4 stakeholders and 34 RBMs [97.1%]) expressed willingness to continue using the system and 33 (84.6%) reported analyzed data were used for decision-making. Public health facilities constituted the main data source. Overall, 65.0% of funding were from partner agencies. Trend of malaria cases showed significant decline (χ2trend = 7.49; P = 0.0006). Timeliness of reporting was below the target (≥ 80%), except being 82% in 2012. CONCLUSIONS Malaria surveillance system in Kano State was simple, flexible, acceptable, useful and donor-driven but the data were not representative of all health facilities. Timeliness of reporting was suboptimal. We recommended reporting from private health facilities, strengthening human resource capacity for supportive supervision and ensuring adequate government funding to enhance the system's representativeness and improve data quality.

2013-2016年，尼日利亚卡诺州疟疾监测系统评估。

背景技术加强疟疾监测系统对于消除疟疾的进展至关重要。在尼日利亚，随着该国努力实现消灭，最近对此给予了更多关注。但是，监视系统的性能充满挑战，包括数据质量差，状态各不相同。这项研究评估了卡诺州疟疾监测系统的运行并评估了其关键属性。方法采用观察性研究设计，包括调查，记录审查和辅助数据分析以及混合方法数据收集方法。就该系统的运行情况和监测系统的属性进行了四个主要的利益相关者和35个遏制疟疾联络人（RBM）半结构化访谈。我们分析了基于网络的2013-2016年国家卫生管理信息系统摘要疟疾数据集。使用“ 2001年美国疾病控制中心更新的评估公共卫生监视系统的指南”对监视系统进行了评估。使用均值，标准差，频率和比例描述数据。卡方曲线用于线性趋势。结果总体而言，有24个RBM（68.6％）具有≤15年的疟疾监测经验，有29个（82.9％）具有正规的疟疾监测培训；报告的32种基于结果的管理（91.4％）的案例定义易于使用，报告的表格易于填写，数据流渠道也得到明确定义。二十七名受访者（69.2％）报告说数据工具可以适应变化，并且所有成果管理制都了解疟疾病例定义。所有受访者（4个利益相关者和34个RBM [97.1％]）表示愿意继续使用该系统，有33个（84.6％）报告的分析数据用于决策。公共卫生设施是主要数据来源。总体而言，65.0％的资金来自合作伙伴机构。疟疾病例趋势呈明显下降趋势（χ2趋势= 7.49； P = 0.0006）。报告的及时性低于目标（≥80％），除了在2012年为82％。结论卡诺州的疟疾监测系统简单，灵活，可以接受，有用且由捐助者推动，但数据并不代表所有医疗机构。报告的及时性欠佳。我们建议从私人医疗机构报告，加强人力资源支持监督的能力，并确保政府有足够的资金来加强该系统。
