Course Description

Healthcare data can vary greatly from one organization to the next. Data are collected for different purposes, such as provider reimbursement, clinical research, and direct patient care. These data may be stored in different formats using different database systems and information models. And despite the growing use of standard terminologies in healthcare, the same concept (e.g., blood glucose) may be represented in a variety of ways from one setting to the next.

The goal of this course is to teach you the fundamentals of the OMOP Common Data Model (OMOP-CDM) and its Standardized Vocabularies that aims to strongly improve the interoperability of healthcare data. We will help you to better understand the conventions of the OMOP-CDM and its table structure. We start with an introductory video about the Observation Health Data Sciences and Informatics (OHDSI) initiative and will then dive into the OMOP-CDM and the Standardized Vocabularies.
OMOP-CDM

For more information about OHDSI have a look at the OHDSI website. Detailed information about the data model can be found on the Github Wiki.

    The Standardized Vocabularies

    Free

    During this part of the course we will be studying the OHDSI Standardized Vocabularies by running queries against the SYNPUF CDM we loaded on a SQL Server instance in the Microsoft Azure cloud (if you have obtained access). Alternatively, you could use your own CDM instance for these exercises.

    Instructions on how to connect to our CDM are provided during the face-to-face course.
