The Unified Research data Sharing and Access (URSA) Initiative was launched in 2015 with the overall goal of making electronic health record (EHR) and other health data accessible and usable for research purposes across Rhode Island. This initiative is supported by Advance RI-CTR and coordinated by the Advance RI-CTR Biomedical Informatics, Bioinformatics, and Cyberinfrastructure Enhancement (BIBCE) Core with leadership and expertise provided by the Brown Center for Biomedical Informatics (BCBI).

The Advance RI-CTR BIBCE Core collaborates with Brown University's Office of Information Technology and the Division of Research, including Research Integrity and Research Agreements & Contracting, and health data partners across Rhode Island to:

• Coordinate processes for health data sharing and secure access within and across institutions;

• Develop the requisite legal, ethical, and technical infrastructure between Brown and health data sharing partners;

• Establish cross-institutional governance, including standard policies, procedures, and protocols for appropriate sharing and use of health data; and,

• Provide documentation and training for health data requests, access, and use.

Through the URSA Initiative, the BIBCE Core provides expertise and infrastructure for conducting research using large-scale health datasets. The BIBCE Core is available to help researchers navigate the process of identifying options and solutions for storing, managing, and analyzing data from health data partners or other data sources.

This page describes various synthetic and de-identified health datasets available to researchers.

SyntheticRI

The SyntheticRI datasets were generated by the Brown Center for Biomedical Informatics (BCBI) for use in research and education. These datasets contain realistic but fictional residents of the state of Rhode Island. The synthetic population aims to statistically mirror the real population in terms of demographics, disease burden, vaccinations, medical visits, and social determinants.

• SyntheticRI Demo: synthetic data representing 1,188 Rhode Island individuals of all ages

• SyntheticRI Adult: synthetic data representing 145,010 Rhode Island adults, ages 19-99

• SyntheticRI Peds: synthetic data representing 145,010 Rhode Island children, ages 0-18

The SyntheticRI datasets were generated using , an open-source, synthetic patient generator. The Synthea-generated datasets are in .csv file format.

Each dataset was also transformed to the OHDSI OMOP Common Data Model (CDM) using the Observational Health Data Sciences and Informatics (OHDSI) Consortium's program . These datasets can be accessed though direct database queries or with such as ATLAS and HADES.

MIMIC-IV (Medical Information Mart for Intensive Care) is a large, freely-available relational database comprising deidentified health-related data from real patients who were admitted to the critical care units of the Beth Israel Deaconess Medical Center in Boston, Massachusetts, USA.

MIMIC-IV contains comprehensive information from 2008-2019 for over 60,000 hospitalized patients. The database is intended to support a wide variety of research in healthcare. MIMIC-IV builds upon the success of MIMIC-III, and incorporates numerous improvements over MIMIC-III.

Refer to for more information about MIMIC-IV. Researchers interested in accessing the complete MIMIC-IV dataset should follow .

The (HCUP) is a family of databases, software tools, and related products developed through a Federal-State-Industry partnership and sponsored by the Agency for Healthcare Research and Quality (AHRQ). HCUP databases are derived from administrative data and contain encounter-level, clinical, and nonclinical information including all-listed diagnoses and procedures, discharge status, patient demographics, and charges for all patients, regardless of payer, beginning in 1988.

HCUP offers the following databases:

• National (Nationwide) Inpatient Sample (NIS): largest publicly available all-payer hospital inpatient care database in the United States

• Kids' Inpatient Database (KID): hospital inpatient stays for children and is specifically designed to allow researchers to study a broad range of conditions and procedures related to children's health

• Nationwide Emergency Department Sample (NEDS): emergency department (ED) visits that do not result in an admission as well as ED visits that result in an admission to the same hospital

Please note: Access to HCUP databases is not free. Database releases must be purchased through the .

The Surveillance, Epidemiology, and End Results (SEER) Program provides information on cancer statistics in an effort to reduce the cancer burden among the U.S. population. SEER collects cancer incidence data from population-based cancer registries covering approximately 47.9 percent of the U.S. population. The SEER datasets include data on patient demographics, primary tumor site, tumor morphology, stage at diagnosis, and first course of treatment.

SEER offers the following datasets:

• SEER Research Data

  • Register with any valid email

  • Excludes geography, month and year of diagnosis, and other demographic fields

SyntheticMass is a Synthea-generated data set that contains realistic but fictional residents of the state of Massachusetts. The synthetic population aims to statistically mirror the state population in terms of demographics, disease burden, vaccinations, medical visits, and social determinants. Refer to the for more information.

There are several data sets available on the .

• Complete SytheticMass data sets: "SyntheticMass Data Version 2 (24 May, 2017)". This ZIP file is quite large (21GB), so make sure you move the file to a location with enough storage before attempting to unzip.

• Sample data sets (<100MB) containing 100 or 1,000 patient records

• Specialized data sets that have been generated using Synthea by other study teams. These include COVID-19 data sets, a Childhood Obesity data set and more.

The following versions are available for each data set.

• CSV ( describing all CSV tables)

• C-CDA (xml files)

• FHIR (json files)
