Abstract
Background
Leptospirosis is included in the list of diseases of compulsory notification in Brazil.
Objective
To evaluate the leptospirosis epidemiological surveillance system in the municipality of Campinas, state of São Paulo, Brazil, between 2007 and 2014.
Method
A study on the prevalence of leptospirosis cases was carried out in the epidemiological surveillance system. A total of 2949 reported cases were analyzed considering the attributes of the Updated Guidelines for Evaluating Public Health Surveillance Systems and the parameters proposed by Souza et al. (2010) for the National Epidemiological Surveillance System. The following attributes were assessed: completeness, acceptability, sensitivity, positive predictive value, representativeness, and timeliness.
Results
The following percentages were found for the respective attributes: completeness (94.1%), acceptability (68.3%), positive predictive value (10.7%), representativeness (98.4%) and timeliness (71.4%).
Conclusion
The leptospirosis epidemiological surveillance system in Campinas presented acceptable completeness and good positive predictive value of disease suspicion. Delays in the notification and investigation of cases and poor integration between the information systems were observed. The evaluation of the surveillance system provides important information for the organization of health services and should be part of the routine of actions provided for in the system. This study can be used as a model to evaluate information systems of other noticeable diseases.
