2 PhUSE 2010 Conference - CDISC and Industry Standards Discussion Club - Tuesday, October 19th 2010 Sintero Server is a prototype distributed clinical computing platform funded by Wellcome Trust Translational Programme It tries to Simplify INTEROperability in large-scale healthcare & clinical research applications It aims to be highly cost-efficient with low ‘footprint’ to ‘defragment’ collaborative processes It is based on an internationalised software “stack” intended to work the same way everywhere

3 PhUSE 2010 Conference - CDISC and Industry Standards Discussion Club - Tuesday, October 19th 2010 Sintero is an internationally-distributed collaborative computing platform. For assisting translation, it is targeted equally into two areas: 1. Affordable healthcare initiatives - providing new “low-cost and scalable” options for open source clinical data “node” infrastructures and patient-centred service hosting. For example, “commodity interoperability” solutions that are portable. Through internationalised software “stack” implementations they work the same way everywhere. 2. Standard computational workflows for translational research – i.e. chained blocks of standard executable server code harmonising multi-site (especially international) clinical research collaborations. These absolutely depend on assisting the collaboration “nodes” to use single semantic/syntax standards. Sintero is designed to implement/deploy any externally defined semantic model and work with multiple EHR’s and EDC systems. Distributed Collaborative Computing Low-cost replicable ‘STACK’ ~ creates ‘LOCAL’ TRUSTED SERVER ‘NODES’ e.g. Collaboration A e.g. Collaboration B Trusted nodes are portable: and reconfigurable: …and scalable: LOCAL DATA STORAGE NODE
