Quality of tuberculosis information systems after record linkage

ABSTRACT Objective: to analyze the quality of a tuberculosis notification information system after record linkage and spatial and temporal distribution of tuberculosis in a Brazilian state. Method: an ecological study carried between 2006 and 2016 in Sergipe, Brazil. A deterministic linkage was performed with Notifiable Diseases Information System and Mortality Information System, recording 7,873 cases and 483 deaths. The temporal trend of tuberculosis incidence was calculated. Results: there was an increase among men (2.75%), > 60 years (6.29%), higher education (4.34%) and indigenous (4.76%). A total of 190 new cases (2.9%) was found. There was an increasing trend in tuberculosis incidence with a concentration of deaths in the metropolitan region. Conclusion: the quality of the information system showed fragility in identifying cases and deaths in Sergipe. Temporal distribution showed an increasing trend in tuberculosis incidence, and spatial distribution identified higher incidences in southeastern Brazil.

摘要
研究目的：分析巴西塞尔希培州（Sergipe）的结核病报告信息系统在实施记录匹配（record linkage）后的质量，以及该州结核病的时空分布特征。
研究方法：本研究为生态学研究，于2006年至2016年在巴西塞尔希培州开展。通过确定性记录匹配，将法定传染病报告信息系统（Notifiable Diseases Information System）与死亡登记信息系统（Mortality Information System）进行数据关联，共纳入7873例病例与483例死亡案例。同时计算了结核病发病率的时间变化趋势。
研究结果：男性群体（增幅2.75%）、60岁及以上人群（增幅6.29%）、接受高等教育人群（增幅4.34%）及原住民群体（增幅4.76%）的结核病发病率均呈上升趋势；共发现190例新增病例，占总病例数的2.9%；结核病整体发病率呈上升趋势，且死亡病例集中分布于大都市区。
研究结论：塞尔希培州的结核病报告信息系统在病例与死亡病例识别环节存在薄弱环节。时间分布特征显示结核病发病率呈上升趋势，空间分布特征则显示巴西东南部地区的结核病发病率更高。
