InfoSAS: a data mining system for production control of SUS [Brazilian public healthcare system]

Abstract

This paper introduces InfoSAS, a system for detection of statistical anomalies in SUS production records. InfoSAS finds per capita inhabitant service rates
that are much higher than the Brazilian average or hospitalization prices way over those charged by most institutions for the same procedure. Results show that
hundreds of millions of Brazilian Reais spent by SUS are destined for treatments considered anomalous based on conservative criteria.
