@contentandwell This is a very good point. Thankfully SRTR has a risk-adjustment model that takes into account donor and recipient characteristics. When looking at SRTR graft or patient survival outcomes it’s important to look at the percentage that is listed for, “Expected probability of surviving…” which will say, “(adjusted for patient and donor characteristics)” beneath it. This means that the percentage takes into account the unique characteristics of that center’s transplant patients. For example, Mayo Clinic often takes on high-risk cases that other centers turn away and this is accounted for in SRTR’s expected probability percentages but is not accounted for in SRTR’s estimated probability percentages.
We know this can be a bit confusing so in our recent blog post on” Using the Scientific Registry of Transplant Recipients” we walk through a specific example of this from one of our campuses, if you are interested take a look at #5 in the post: https://connect.mayoclinic.org/newsfeed-post/transplant-resource-using-the-scientific-registry-of-transplant-recipients/
