3D Rendering Prior to an Arthroplasty Procedure

(Matt Spotnitz) #1

Hi Everyone,

I am pleased to announce a study about the association between preoperative use of 3D rendering before a total knee arthroplasty (TKA), total shoulder arthroplasty (TSA), or total hip arthroplasty (THA) and postoperative outcomes. This is a joint proposal that has been developed by Columbia University Medical Center and the University of Oxford. It would be terrific to have other sites from the OHDSI community to participate in this study. The link to the population level estimator can be found here:


For those who are interested in preliminary counts, here are the links for each cohort:

Please let me know if I can provide you with any additional information. Thank you so much!

Hi @mattspotnitz! Count the IQVIA team in. Can you direct us to the GitHub repo?

That’s terrific, Kristin, thank you so much! Our goal is to get the study done within 3 weeks so we have time to submit an abstract to this conference:


I will direct you to the GitHub repo when the software is ready.

Hi @mattspotnitz and @edburn
How is this one moving? Anything we can do to help?

@Daniel_Prieto, @mattspotnitz is making great progress! I believe we have some results from Columbia and Stanford already, with more to come…

(Daniel Prieto-Alhambra) #6

Awesome!!let me know how I can have a peek?!

(Kristin Kostka, MPH) #7

@schuemie’s first rule of p-hacking: no peeking! :wink:

@krfeeney I think the rule of thumb to avoid p-hacking is no HARKing (hypothesizing after the results are known.), technically. :slight_smile:
