Cross-border epidemiological data integration and harmonization – Application to malaria in the cross-border area between French Guiana and Brazil

Context Ensure healthy lives and promote well-being for all at all ages Target: By 2030, end the epidemics of AIDS, tuberculosis, malaria and neglected tropical diseases and combat hepatitis, water-borne diseases and other communicable diseases • Malaria: 216 million cases and 445 thousand deaths worldwide in 2016 (WHO, 2017) • Between 2000 and 2015, 58% and 37% decreases of the mortality and incidence rates, respectively • Socio-demographical and environmental contexts that vulnerabilize local populations • High mobility of pathogen-carrying populations • Patient follow-up difficulties (situations of illegality, auto-medication, ...) • Different strategies and means of surveillance, prevention and control of diseases between countries • Lack of international cooperation: Few regular exchange of comparable data and information between countries ⇒ Heterogeneous data types and formats, nomenclatures and concepts How to ensure cross-border epidemiological data interoperability on an ongoing basis? FTP server Computation and display application (R/Shiny) Harmonized DB Rebuilt DB Rebuilt DB Automated processing chain Integration and harmonization Indicator computation and visualization CHAR/CDPS Cayenne, FG Objectives and challenges • Integrate and harmonize automatically and regularly malaria cross-border epidemiological data • Disseminate indicators and data in an interpretable way for specialists, health actors and population In fine, this should conduct to • Provide a unified vision of the epidemiological cross-border situations • Participate to define concerted, targeted and effective control actions for disease elimination Cross-border malaria considered as a "Major obstacle for malaria elimination" [Wangdi et al., 2015] Paris France Study Region Ethical considerations • Exploitation and dissemination of anonymized data • Temporal and spatial aggregation of the data for public user profile • Authorization of the Commission Nationale de l'Informatique et des Libertes (CNIL) for personal data automatic processing and data transmission to a foreign country (ongoing request No. 2135463) • Multi-platform Extract Transform Load (ETL) tools (TALEND®) Harmonization rules based on expert knowledge in epidemiology and parasitology • Web services for data online publication • Web application (R-Shiny) for online data visualization CDPS ...
