Everis is an NTT Data company, dedicated to consulting and outsourcing in all sectors, with teams across Europe, USA and Latin America. They were contracted by the Mexican Health Ministry to develop “SINBA”, which is a new platform which integrates 19 different systems that collect information about births, deaths, hospital discharges, violent acts, emergency incidents, chronic diseases, public health insurance and medical providers. This information had been collected for several years across 6 federal institutions and hundreds of private providers in more than 10,000 facilities across Mexico. The problem was that there was no unique identity to provide cross-domain and cross-institutional statistics. The Mexican Health Ministry required customized characteristics that did not exist in any existent MPI software and a volume of 130 million citizens must be supported.

Team TrueTech developed a Master Person Index using Java EE, Oracle Exadata and Oracle Data Integrator (ODI). The Fellegi-Sunter probabilistic record linkage methodology was implemented with 25 matching algorithms customized for Mexican names with spanish phonetics.

The system now delivers 400 billion probabilistic matches per second executing over a 1 billion records to gather 130 million unique identities. This has provided an annual savings of over $350 million to the Mexican Health Ministry by detecting duplicates entries on publicly insured patient records. They are also now able to confidently report on their gathered statistics and use this data to continue to improve their processes on a regular basis.
