OHDSI Symposium 2023 - Phenotype Development and Evaluation Workgroup meeting

Are you interested in leading an OHDSI characterization study?

The Phenotype Development and Evaluation Workgroup is pleased to announce an in-person meeting scheduled at the 2023 OHDSI Global Symposium on Saturday, October 21, 2023, from 9:00 am to 12:00 pm. The OHDSI Phenotype Development and Evaluation has the Objective Key Result (OKR) to “a) harden Phenotype development and evaluation, b) Improve collaboration by enabling community wide participation on Phenotype Development and Evaluation, c) Promote the usage of OHDSI Phenotype library.” One of the key results of this workgroup is to enable scientists to use the OHDSI Phenotype Library to perform collaborative scientific research for peer reviewed publications.

To further this key result, we aim to utilize the OHDSI Symposium 2023 as a collaboration opportunity to enable scientists to lead OHDSI studies that leverage the Cohort Definitions available in the OHDSI Phenotype library. The leads will be enabled to use the characterization evidence generated for the cohort definitions in OHDSI phenotype library for peer reviewed publications. See last paragraph below on the opportunity to lead a paper.

We will start by first picking a subset of cohort definitions in the OHDSI Phenotype library that were chosen to be part of the ‘How Often’ incidence rate analysis. Once we determine they have reasonable operating characteristics, we will supplement the incidence rate results of HowOften with population-level characterization data derived from the OHDSI software CohortDiagnostics (CD). The combination of the two may be used by study leads and their collaborators to write scientific research papers for peer reviewed publications.

The session aims to achieve the following outcomes:

  1. Complete assessment of potential measurement errors associated with the cohort definitions featured in the ‘How Often’ study across all data sources involved.
  2. Perform descriptive analytics of the target/outcome cohorts in the ‘How Often’ study.
  3. Write a manuscript on the insights gained and submit for peer reviewed publications.

We welcome participation from:

  1. OHDSI collaborators and data partners interested in leading (i.e. first author) or contributing (co-author) significantly to a research paper on a phenotype.
  2. OHDSI data owners who would like to contribute to the population level characterization component of the study by running CohortDiagnostics in addition to Incidence Rate analysis of HowOften.
  3. Individuals who want to gain technical experience in running CohortDiagnostics on your data site.
  4. Individuals who are interested in reviewing and interpreting the output from CohortDiagnostics or phevaluator and learn how to identify potential measurement errors.

We are looking for volunteer study leads. If you wish to lead a characterization study as the lead investigator, we encourage you to contact the workgroup leaders via email at rao@ohdsi.org . If selected, similar to the OHDSI Phenotype Phebruary 2023, the workgroup leaders @Azza_Shoaibi, @Gowtham_Rao will offer help to the volunteer leads throughout the project. We will enable you in assessing the operating characteristics of definitions, identifying potential error sources, interpreting the characterization results, and facilitating manuscript preparation for peer-reviewed publications. Collaborators with all levels of experience are welcome.
