Weekly OHDSI Digest – January 22, 2024


Please join our next community call on Tuesday, Jan. 23 (11 am ET) for a session focused on the recent UK Study-A-Thon, held last November at Saint Hilda’s College. The event focused on use of fluoroquinolones across geographies and over time, as well as on the epidemiology and characterization of rectal prolapse and rectopexy. At the end of an intense week, the team generated three draft manuscripts almost ready for submission, and at least four conference abstracts were in the making.

We will hear from leaders from the Study-A-Thon during the call:

• Daniel Prieto-Alhambra – Professor of Pharmaco- and Device Epidemiology,

University of Oxford

• Katherine Donegan – Head of Epidemiology, MHRA

• Jennifer Lane – NIHR Clinical Lecturer in Trauma and Orthopaedic Surgery, Barts Bone and Joint Health, Queen Mary University of London

• Annika Jodicke – Senior Researcher in Pharmacoepidemiology, University of Oxford

Everybody is invited. Calendar invites went out last week. If you did not receive one, please use this link to join the meeting. All recordings from these weekly calls are available within our Teams environment and will be posted on both our YouTube page and our OHDSI.org Community Calls page.
