Population-Level Estimation Workgroup

Objective:

Develop scientific methods for observational research leading to population level estimates of effects that are accurate, reliable, and reproducible, and facilitate the use of these methods by the community.

Specific goals:

Develop the Health Analytics Data-to-Evidence Suite (HADES)
Specify OHDSI Best Practices for Estimating Population-Level Effects

Start Date: March 5, 2014

Meetings

Because of time differences we have separate meetings for the Eastern (Asia-Pacific) and Western (Europe + Americas) hemispheres. Starting 2020, the Population-Level Estimation meetings will be combined with the Patient-Level Prediction meetings

Eastern hemisphere

Meetings are held on the first Wednesday of every month. Next meeting:

September 2, 2020

Meetings will take place at these times (DST where appropriate):

5pm Sydney
4:30pm Adelaide
4pm South Korea
3pm Hong Kong / Taiwan
9am Central European time
8am UK time
