There are plenty of ways to learn more about our community. From our data standards to our methods and clinical research to our open-source development and collaborative activities, OHDSI continues to evolve around our mission of improving health by empowering a community to collaboratively generate the evidence that promotes better health decisions and better care.
Below are a few examples of ways you can learn more about the community.
Book Of OHDSI
Published in 2019, the Book of OHDSI (book.ohdsi.org) aims to be a central knowledge repository for OHDSI, and it focuses on describing the OHDSI community, OHDSI data standards, and OHDSI tools. It is intended for both OHDSI newcomers and veterans alike, and aims to be practical, providing the necessary theory and subsequent instructions on how to design and implement research yourself.
You will learn about the OMOP common data model and standard vocabularies, and how they can be used to standardize an observational healthcare database. You will learn about three analytic use cases for these data: characterization, population-level estimation, and patient-level prediction. You will read about OHDSI’s open-source tools and how they can be applied to your data and how you can design and implement your own analyses following OHDSI’s best practices. Chapters on data quality, clinical validity, software validity, and method validity will explain how to establish the quality of the generated evidence. Lastly, you will learn how to use the OHDSI tools to execute these studies in a distributed research network.
The Book of OHDSI is available for free online in English, Korean and Chinese, and can also be purchased through Amazon (all links are available in our menu above).
The EHDEN Academy
The EHDEN Academy (academy.ehden.eu) serves as a free, publicly available online educational resource for anyone working in the domain of real-world data and real-world evidence. Originating in the European Health Data & Evidence Network (EHDEN) IMI2 project, its goal is to build upon the foundations of that project and its collaboration with the OHDSI community. It is currently used across ~70 countries and has ~2900 enrollees. The EHDEN Academy is a resource on tools, methods and skills for all those who generate and utilize data, work technically with it (e.g. ETL and mapping), and are involved in methodological development and the use of standardized analytical tools.
YouTube Tutorials + Presentations
The OHDSI YouTube channel includes past tutorials and presentations made in community calls and global symposia and other community events, including the 2022 DevCon event. The page currently includes more than 400 hours of community-developed content, including each session of the 2022 Symposium tutorial, An Introductory Journey from Data to Evidence. There are specific playlists devoted to tutorials and workshops, past symposia, community calls, etc.
As a transparent, open community, we believe that posting our questions, answers and comments in the public domain is the best way for us all to learn together. The OHDSI forums provides an open venue for all members of the community to seek and provide help from fellow collaborators around the world. There are more than 5,500 different threads across a variety of categories within our forums. Have a question? This is a great starting point!
The Our Journey publication is an annual report that provides a high-level overview of all aspects of the OHDSI community, including its start and global mission, the OMOP Common Data Model and global data network, its collaborative activities and publications, and plenty more. The 2022 version includes a map of its 453 data partners, new details on the HADES open-source tools, information on OHDSI vocabularies and recent methodological research, and plenty more. The book is distributed at the global symposium, but a PDF of the book is available via download.
