Joint Concordance Index [article]

Kartik Ahuja, Mihaela van der Schaar
2019 arXiv   pre-print
To address these limitations, we propose a new metric, which we call the joint concordance.  ...  The joint concordance measures a model's ability to predict the overall risk profile, i.e., risk of death from different event types.  ...  Software The code for the joint concordance index is available at 1 . We also developed an application, which is available at 2 .  ...

Reliability of self assessed joint counts in ankylosing spondylitis

A Spoorenberg
2002 Annals of the Rheumatic Diseases  
The agreement on individual tender joints was again poor to moderate (κ 0.19-0.43). There was only high concordance between doctors and patients on the absence of swollen joints (82%).  ...  The concordance on the presence of monoarthritis, oligoarthritis, or polyarthritis was low (17-22%).  ...  Again the concordance rates were very low for all groups of tender joints, and for the various levels of swollen joints. The only good concordance rate was in the absence of swollen joints.  ...

Validity of Same-Side Reoperation After Total Hip and Knee Arthroplasty Using Administrative Databases

Stephen Lyman, Warren Dunn, Chris Spock, Peter Bach, Lisa Mandl, Robert Marx
2009 The journal of knee surgery  
Concordance was defined as the percentage of same-side reoperations. Overall concordance was 23% for THR and 22% for TKR, suggesting most reoperations were on the contralateral hip or knee.  ...  In a hospital-based sample of patients undergoing multiple THR or TKR, the side of the index operation was compared with the side of the subsequent operation.  ...  Age-specific and gender-specific concordance was calculated, as was concordance by time between index surgery and second surgery.  ...
