Novel Approaches and Challenges to Data Harmonization: Maximizing the Use of Multi-level Data in Collaborative Studies

The Novel Approaches and Challenges to Data Harmonization Workshop, sponsored by the Epidemiology and Genomics Research Program (EGRP), will be held on October 6-7, 2014, at the Neuroscience Center Building in Rockville, Maryland.


Overview

The breadth and scope of studies utilizing an epidemiologic framework has grown significantly during the last few decades. This trend is mainly due to the increasing complexity of the research questions being asked and the consequent need to coalesce data across many studies. In fact, the case has been made that "integrative epidemiology"--the integration and analysis of heterogeneous and multi-layered data sets—may be the key to advance the practice of epidemiology in the twenty-first century.

The current climate of scarce resources necessitates assembling these expansive and heterogeneous data sets through extensive multi-disciplinary collaboration or consortia. Throughout the last decade, consortia-based research has grown exponentially, has contributed to a better understanding of the complex etiology of cancer, and has provided fundamental insights into key environmental, lifestyle, clinical, and genetic determinants of these diseases and their outcomes. Using existing epidemiology data sets and complementing them with newly acquired genomic, clinical and other types of data can empower researchers to address important health issues more expeditiously and in a more cost-effective manner than through the creation of new large research infrastructures. Data harmonization, or the process of assessing compatibility of data accrued from independent sources, is an essential step to support these integrative analyses.

The goals of the Novel Approaches and Challenges to Data Harmonization Workshop are:

  1. To explore the theory and practice of multi-level data harmonization;
  2. To consider available tools and new approaches;
  3. To review representative case-studies; and
  4. To develop recommendations for best practices.
