Chapter 1 Preface

Automated Characterization of Health Information at Large-scale Longitudinal Evidence Systems (ACHILLES) is a profiling tool developed by the OHDSI community to provide descriptive statistics of databases standardized to the OMOP Common Data Model. These characteristics are presented graphically in the ATLAS tool. However, this solution does not allow for database comparison across the data network. The Data Network Dashboards aggregates ACHILLES results files from databases in the network and displays the descriptive statistics through graphical dashboards. This tool is helpful to gain insight in the growth of the data network and is useful for the selection of databases for specific research questions. In the software demonstration we show a first version of this tool that will be further developed in EHDEN in close collaboration with all our stakeholders, including OHDSI.

Contributors

To develop this tool, EHDEN organized a hack-a-thon (Aveiro, December 2-3, 2019), where we defined and implemented a series of charts and dashboards containing the most relevant information about the OMOP CDM databases. The team involved in this task were composed by the following members:

  • João Rafael Almeida1
  • André Pedrosa1
  • Peter R. Rijnbeek2
  • Marcel de Wilde2
  • Michel Van Speybroeck3
  • Maxim Moinat4
  • Pedro Freire1
  • Alina Trifan1
  • Sérgio Matos1
  • José Luís Oliveira1

Considerations

This manual was written to be a guide for a clean installation of this system with all the dashboards that we defined during the project. The first chapter describes the goal of the system and the second how to install the system. The remaining chapters are dedicated to the dashboards, in which chapters describes one dashboard and all its charts. To simplify the representation of the dashboard’s layout, we used similar schemas as it is presented in Figure 1.1. The white box is the dashboard and the inside boxes are charts. The colour changes in relation to the type of chart.
