VIEIRA, Marcelo Adriano da Cunha e Silva et al. Proposal for a simplified approach to suspected meningitis case diagnosis: experience report of a reference service in the state of Piauí, Brazil, 2007-2016. Epidemiol. Serv. Saúde [online]. 2018, vol.27, n.3, e2017329.  Epub Oct 22, 2018. ISSN 1679-4974.


to describe a simplified protocol to diagnose suspected cases of meningitis.


this is an experience report on the approach to diagnosing meningitis at the Tropical Diseases Reference Service in the state of Piauí, Brazil, between 2007 and 2016; information was extracted from the Notifiable Diseases Information System (SINAN) and the laboratory record book; the chi-square test was used to compare epidemiological surveillance indicators based on final meningitis case classification; the Phi coefficient was used to verify the correlation between presumed diagnosis and laboratory-confirmed diagnosis.


considering the 4,096 cases of meningitis investigated, there was a reduction in the generic classification of meningitis cases from 72% to 47% (p<0.001); indicated laboratory investigation profile showed agreement with final meningitis case diagnosis. (rf=0.66; p<0.001).


a greater proportion of specific etiologic diagnosis of meningitis was achieved while the protocol was in use.
