Abstract

Numerous kidney exchange (kidney paired donor (KPD)) registries in the U.S have gradually shifted to high frequency match-runs, raising the question of whether this harms the number of transplants. We conduct simulations using clinical data from two KPD registries-the Alliance for Paired Donation, which runs multi-hospital exchanges, and Methodist San Antonio, which runs single center exchanges-to study how the frequency of match-runs impacts the number of transplants and the average waiting times. We simulate the options facing each of the two registries by repeated resampling from their historical pools of patient-donor pairs and non-directed donors, with arrival and departure rates corresponding to the historical data. We find that longer intervals between match-runs do not increase the total number of transplants, and that prioritizing highly sensitized patients is more effective than waiting longer between match-runs for transplanting highly sensitized patients. While we do not find that frequent match-runs result in fewer transplanted pairs we do find that increasing arrival rates of new pairs improves both the fraction of transplanted pairs and waiting times.

Attention Score in Context

This research output has an Altmetric Attention Score of 13. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 13 November 2017.
All research outputs
#733,506
of 8,658,076 outputs
Outputs from American Journal of Transplantation
#200
of 2,176 outputs
Outputs of similar age
#20,336
of 160,342 outputs
Outputs of similar age from American Journal of Transplantation
#3
of 32 outputs
Altmetric has tracked 8,658,076 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 91st percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 2,176 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.6. This one has done particularly well, scoring higher than 90% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 160,342 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 87% of its contemporaries.
We're also able to compare this research output to 32 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 90% of its contemporaries.
