“…In this sense, it is necessary to generate performance indicators (effectiveness, cost, adverse events among others) of the technologies in use and not only production indicators. This is possible due to the availability and access to SUS health information systems (mortality information system -SIM in Portuguese, hospital information system -SIH-SUS in Portuguese, outpatient information system -SIA-SUS in Portuguese, among others) (DATASUS, 2013) and the possibility of integrating the data records of these systems (Freire et al, 2012;Gomes and Almeida, 2004;Pires, 2011;Queiroz et al, 2009;Santos and Gutierrez, 2008). In cancer care, studies have demonstrated the possibility of linking records for generating indicators for the estimation of the required infrastructure, the follow up of clinical guidelines and the effectiveness of a screening program (Bastos, 2011;Costa, 2005;Gomes and Almeida, 2009).…”
