Democratizing data access for clinical researchers to improve healthcare quality and delivery

We aim to facilitate a pathway to pursue data-centric research that improves healthcare quality and delivery. We accomplish this by democratizing data access for clinical and non-clinical researchers. We provide a platform to share resources to achieve economies of scale and facilitate new research projects that increase the velocity of evaluation, insights and discovery.

Core Services

The core's focus is to provide the data infrastructure and streamlined access to the emergence of health services research encompassing outcomes research, quality improvement, and implementation science with a focus on providing these services:

  • Our data repository helps researchers observe population-level outcomes that translates into real health benefits to society.
  • Data to assist in the delivery of recommended timely care to the right patient.
  • We support study design and initiation, grant and manuscript writing, and submission.

October 2022 – Vagus Nerve Stimulation in Humans

University of Minnesota awarded $21M to lead research revealing effects of vagus nerve stimulation in humans

The Research Evaluating Vagal Excitation and Anatomical Links (REVEAL) project is a $21 million NIH-funded project that will take place over three years. REVEAL aims to study the anatomical connections and functional effects of vagus nerve stimulation, which is an FDA-approved treatment for epilepsy and depression.

From the University of Minnesota, the study team includes faculty from multiple departments across the Medical School, the College of Science and Engineering, and the School of Public Health. These faculty also represent the Center for Neuroengineering, the Institute for Engineering in Medicine, the Clinical Quality Outcomes, Discovery and Evaluation (CQODE) Core and the Minnesota Consortium for Autonomic Neuromodulation.
