Registry evidence vs RCTs: which should we believe?

412 412 people viewed this event.

Using clinical examples, we will show the pros and cons of Registry evidence and RCT evidence and contrast and compare the two data sources. The session will cover how we can generate causal assumptions from observational evidence and will describe the many traps that we fall into when interpreting evidence from both sources. Specifically, we will talk about the contrasting evidence for bipolar v unipolar hemiarthroplasty for hip fractures and will provide broader examples of where evidence from these two sources has differed in the past. We will also describe steps that have been taken to combine the strengths of these two data sources in the form of registry-nested RCTs.

Insights:

  • The limitations of both RCT and observational studies.
  • The unique advantages of each of these study types.
  • How to generate causal inference from observational data.
  • The theory and strengths of registry-nested RCTs
