Subnotificação no Sinan e fatores gerenciais e operacionais associados: revisão sistemática da literatura

Abstract

The objective of this study was to identify the underreporting rates of diseases and compulsory notifiable diseases and harms in the National Notifiable Diseases System (Sinan) and associated management and operational factors. A systematic literature review, with publications searches in the period from 2004 to 2014, on the indexed databases of the Virtual Health Library (BVS); US National Library of Medicine (PubMed); Scopus Collection and Scientific Electronic Library Online (Scielo). Amongst the 509 identified publications, 50 met the inclusion criteria and the analysis categories were described as the coverage of topics that emerged from the included studies. The underreporting indicators or sub records and the associated factors were systematized and they point to weaknesses in reporting processes that reflect in the quality of Sinan data. Actions are needed to overcome difficulties and to potentialize the improvements, so that the health surveillance can operate with consistent data for decision-making in order to improving the population health.
