The United Network for Organ Sharing is planning to resolve the ever-growing geographic disparities in kidney transplantation. Currently available simulation techniques are limited in their ability to analyze the impact of policy changes at the system level. This paper discusses the development of a discrete event simulation of the kidney transplantation(More)
The national demand for kidney transplantation far outweighs the supply of kidney organs. Currently, a patient's ability to receive a kidney transplant varies depending on where he or she seeks transplantation. This reality is in direct conflict with a federal mandate from the Department of Health and Human Services. We analyze current kidney allocation and(More)
Current strategies to improve graft outcome following kidney transplantation consider information at the human leukocyte antigen (HLA) loci. Cell surface antigens, in addition to HLA, may serve as the stimuli as well as the targets for the anti-allograft immune response and influence long-term graft outcomes. We therefore performed exome sequencing of DNA(More)
Sixty-five percent of kidney transplant recipients (KTRs) develop squamous cell carcinoma (SCC). Perceptions of risk of developing skin cancer, amelioration of this risk with sun protection, and having choices among sun protection strategies may enhance sun protection use by KTRS, who are at greater risk than the general population. Thirty KTRs stratified(More)
The United Network for Organ Sharing is planning to resolve the ever-growing geographic disparities in kidney transplantation. Currently used allocation simulation models are limited in their ability to integrate alternative kidney sharing strategies and analyze the impact of policy changes at the system level. This paper introduces a discrete event(More)
Sun protection education is needed for kidney transplant recipients, whose increased risk of skin cancer could be ameliorated with sun protection. Cognitive interviews with 24 participants equally stratified among non-Hispanic White, non-Hispanic Black, and Hispanic/Latino kidney transplant recipients were performed to evaluate a sun protection education(More)
BACKGROUND Perception of skin cancer risk, belief that sun protection prevents skin cancer, and having sun protection choices enhance sun protection behaviors by kidney transplant recipients, who are at greater risk of developing skin cancer than the general population. METHODS A randomized controlled trial used stratified recruitment of non-Hispanic(More)
