Completeness of the tuberculosis information system in the state of Parana, 2008-2017: an ecological study/Completude do Sistema de Informacao em Tuberculose no estado do Parana, 2008-2017: estudo ecologico/Integridad del sistema de informacion sobre tuberculosis en el estado de Parana, 2008-2017: un estudio ecologico

Objective: to examine the completeness of tuberculosis data in Brazil's Notifiable Disease Information System (SINAN). Method: this ecological study considered notified cases of tuberculosis treated in Parana between 2008 and 2017. Data were grouped into notification, follow-up and complementary variables and comprised mandatory and essential information. Completeness was classified as excellent (< 5% incomplete), good (5 to < 10%), regular (10 to < 20%), poor (20 to 50%) and very poor (> 50%). The study complies with Conselho Nacional de Saude Resolution 510/2016. Results: mandatory variables were less than 5% incomplete, and essentials performed very poorly for sensitivity test, smoking and illicit drugs. Completeness in follow-up information worsened over the years, while other groups improved, except in 2014. Conclusion: unsatisfactory completeness in some essential variables, and decreasing completeness in follow-up information, reveal repercussions on bonding between individual and health service, and on case outcomes.
