Abstract

BACKGROUND

Evaluate the Tuberculosis (TB) surveillance system in the Ga West Municipality to determine if it is achieving its objectives, and to assess its attributes and usefulness.

DESIGN

Descriptive analysis of primary and secondary data.

DATA SOURCE

Stakeholder interviews and record reviews on the objectives and operation of the surveillance system at all levels of the system.

INTERVENTION

We evaluated the system's operation from 2011-2015 using the Centers for Disease Control and Prevention (CDC) updated guidelines for evaluating public health surveillance systems and the World Health Organisation (WHO) TB surveillance checklist for assessing the performance of national surveillance systems.

RESULTS

The TB surveillance system in the municipality was functional and operated at all levels for timely detection of cases, accurate diagnosis, and case management. The system improved management of TB/HIV co-infections. The average time taken to confirm a suspected TB case was one day. The registration of a confirmed case and subsequent treatment happen immediately after confirmation. The municipality detected 109 of 727 TB cases in 2015 (case detection rate=15%). The positive predictive value (PPV) was 6.4%. There was one diagnostic centre in the municipality. Private facilities involvement in TB surveillance activities was low (1/15).

CONCLUSION

The Tuberculosis surveillance system in the Ga West Municipality is well structured but partially meeting its objectives. The system is timely, stable and acceptable by most stakeholders and useful at all levels. It has no major data quality issues. Private health facilities in the municipality should be well incorporated into TB surveillance.

摘要

背景

评估加西区的结核病（TB）监测系统，以确定其是否达到目标，并评估其属性和有用性。

设计

对初级和二级数据进行描述性分析。

数据来源

对各级监测系统的目标和运作情况进行利益攸关方访谈和记录审查。

干预措施

我们使用疾病控制和预防中心（CDC）更新的公共卫生监测系统评估指南以及世界卫生组织（WHO）结核病监测检查表，评估了 2011-2015 年期间系统的运行情况，以评估国家监测系统的绩效。

结果

该城市的结核病监测系统在各级都能正常运行，及时发现病例、准确诊断和病例管理。该系统改善了结核病/艾滋病毒合并感染的管理。确认疑似结核病病例的平均时间为一天。在确认后立即登记和随后治疗确诊病例。该城市在 2015 年发现了 727 例结核病病例中的 109 例（检出率=15%）。阳性预测值（PPV）为 6.4%。该市有一个诊断中心。私营医疗机构参与结核病监测活动的比例较低（1/15）。
