New Versus Prevalent User Designs In Pharmacoepidemiology: Time To Get Principled About When We Can Be Pragmatic

 

 

Dr. Til Sturmer
Dr. Jess Edwards

 

Date: January 29, 2020
Time: 12:00 – 1:00pm EST
Online Web Conference

OVERVIEW:

New user designs have become the gold standard in pharmacoepidemiology. However, limiting studies to new users reduces the sample size of epidemiologic studies and often hinders our ability to study the long-term effects of treatments. Prevalent user designs can address these issues, but also bring the potential to introduce serious bias. In this webinar, we describe the mechanics underlying this source of bias and discuss settings where a “pragmatic” prevalent user design may be warranted.

 

OUTLINE:

Minute 0 – 20: Dr. Til Stürmer will introduce the topic and discuss the motivation for new and prevalent user designs

 

Minute 20 – 40: Dr. Jess Edwards will speak for 20 minutes on the mechanics underlying the bias that arises in prevalent user designs and situations where such bias might be expected to be small.

 

Minute 40 – 60: Moderated question and answer session with the audience
