Facilitating the start of yet another OHDSI journey: Welcome UVA Health!

The challenge

University of Virginia Health (UVAH), UVA Health, a world-class medical center and health system based in Virginia, United States, just started their journey with OMOP/OHDSI. The analytics group envisions a centralized database of available health data for internal research purposes and a way to easily collaborate in research studies with external partners. The OMOP Common Data Model (CDM) has been tested on a few occasions, but the overall path to adopt the OHDSI suite in the organization tool stack is yet to be defined.

How we solved it

The Hyve has been working with UVAH to streamline and facilitate the adoption process of the various open-source components of the OHDSI stack by providing hands-on training and tailored education.

The Hyve provided four online sessions to the technical staff at UVAH. The workshop was given by three of our OHDSI experts, Maxim Moinat, Sofia Bazakou, and Anne van Winzum. Before the workshop, our experts sat down with the key stakeholders at UVAH to learn about the ongoing efforts within OHDSI, internal and external data workflows, and current data architecture. The workshop provided the participants with quick access to resources and foundational knowledge on the following topics:

  • The OHDSI community resources, including the forum, working groups, EHDEN Academy and real-time collaborative research such as the Covid-19 studyathon

  • Current OMOP Common Data Model (OMOP CDM V5.3), including a deep dive into the OMOP standardized vocabularies, structure, and conventions, as well as new and ongoing CDM developments, including new OMOP CDM versions (5.4 and 6.0) and the oncology extension

  • A comparison of the OMOP CDM to other healthcare standards such as FHIR, CDISC, Sentinel and i2b2

  • An introduction to the OHDSI ETL and data quality tooling: White Rabbit, Rabbit in a Hat, Usagi, Data Quality Dashboard, CDM Inspection Report and Achilles. Including live demo and exercises for participants.

  • ETL building, best practices and Delphyne.

  • The OHDSI analytic toolset, focussing on the main features of Atlas and how to use these to build your own observational health study.

During the last session, our experts and the UVAH team interactively built an OHDI adoption roadmap for UVAH. The main question was: What is the next step for UVAH in their OHDSI journey? To address this question, The Hyve collected views and opinions of all stakeholders through multiple interactive polls. This exercise provided a better understanding of the direction UVAH wanted to go and ultimately pinpointed areas where additional effort was needed first. After the workshop, the participants were provided with all the materials mentioned and the session recordings.

The outcome

The workshop enabled UVAH to reach a consensus on a clear and concrete plan to move forward with their OHDSI journey.

Starting from a deeper understanding of the steps in the data conversion process aligned with the corresponding components of the OHDSI stack, the team identified and prioritized tasks to be taken up. Leading factors for the prioritization were (1) the highest impact on the data quality and (2) an improvement on collaboration processes in the team.

The workshop was received with great enthusiasm and engagement from UVAH technical staff. We are excited to see workshop participants turn into regular attendees at OHDSI meetings and actively contribute to the working groups.
