Research Informatics

Integrating cutting-edge open-source web development tools and dynamic research data for robust and highly interactive tools for sleep researchers.

Our projects include both internal tools for the Program of Sleep Medicine Epidemiology and Cardiovascular Medicine and external tools that involve collaborators across multiple institutions including the Harvard School of Medicine, Case Western Reserve University, and Johns Hopkins University.

Sleep Portal

The Sleep Heart Health Study is a multi-center cohort study implemented by the National Heart Lung & Blood Institute to determine the cardiovascular and other consequences of sleep-disordered breathing. It tests whether sleep-related breathing is associated with an increased risk of coronary heart disease, stroke, all cause mortality, and hypertension.

The SHHS1 dataset represents data from the baseline and first follow-up visits, collected on 6441 individuals between 1995 and 1998.

The Sleep Portal provides access for investigators to the SHHS baseline visit data and followup data, including datasets, dynamic reports, and associated sleep files (PSG signals and annotations, EEG spectral analysis and summary results).
