The National COVID Cohort Collaborative (N3C) Data Enclave is a resource that is available to ACCEL investigators.
The Enclave currently contains EHR data for over 21 million patients, of which 8.5 million are confirmed COVID-19 positive. The patients are from 83 healthcare organizations across the United States. The patient information is from 2018 to the present. Public datasets from several sources including the US Census and the Social Deprivation Index are available.
Observational Electronic Health Record (EHR) data are an increasingly accessible resource for medical research. Such records are often structured in a Common Data Model (CDM), from which question-relevant information must be extracted, aggregated, and analyzed.
About the Course
This course introduces students to real-world EHR analysis with the N3C, a secure cloud-hosted database with billions of records about millions of patients from dozens of sites across the US. We’ll discuss medical vocabularies and the OMOP CDM, practice querying and analyzing tabular data with SQL and R and see examples of common statistical techniques for observational data. Students will additionally have an opportunity to investigate COVID-19-related questions of their own interest as a course project.
This course consists of 6 sessions that will cover topics including N3C overview and use of the platform, observational research using OHDSI tools, exploring logic liaison templates available in the N3C Enclave, medical terminologies, and best practices for research life cycle.
Registration is open for the short course: Introduction to Analyzing Real-World Data Using the National COVID Cohort Collaborative (N3C).
Dates of the course: January 18, January 25, February 1, February 8, February 15 and February 22
Time: 2-4 CST/3-5 EST
Attendees will need to be onboarded to the N3C Enclave and have access to the course project workspace.
