Newswise – Approximately 9 people waiting for 10 patients waiting for an organ transplant in the US kidney.
Thousands of patients on the list die each year, and thousands more are off the list as their health is getting worse so bad they are no longer considered suitable for transplants. This occurs because a significant number of donated kidneys, currently more than 25%, are now decreasing due to transplantation by all US transplant hospitals.
Transplant center clinicians weigh complex, time-sensitive factors to determine whether to accept or reject the kidneys provided for the transplant.
in the study It is the first of its kind and has great potential to address this national challenge. Glendacher Coworkers have found significant differences in acceptance rates among and among clinicians at the same transplant center. Clinic heterogeneity is significant among clinicians in a particular facility, but both are important.
“Our research is the first to see the heterogeneity at the individual clinician level in the actual decisions they are making,” Dutcher says. “Ultimately, I want to understand whether there is a clear decision-making process at a human level. Is there a difference in how clinicians think about patients and how they think about accepting deceased donor kidneys on their behalf?
The broad field of researcher transplant research is supported by an R01 grant of approximately $1.5 million and an R21 grant of $450,000 from the National Institutes of Health and the National Institutes of Diabetes and Gastrointestinal Diseases and Kidney Diseases.

Important progress
Innovative research is an important step in understanding why differences occur and what it means for patient care and organizational productivity.
“Our hope is that our research serves as a foundation for a deeper understanding of the factors affecting the kidneys, and ultimately leads to strategies and policies that improve the kidney transplant process,” Greene said.
Understanding the dynamics that influence individual clinician decisions – Beyond center-level policies and other center-level factors, it can increase the number of implants, reduce the time people wait for implants, and improve patient outcomes. These clinician-level factors include experience, risk and benefit perceptions, risk tolerance, and ethical considerations.
In a state-of-the-art approach, the researchers analyzed a large anonymized dataset of kidney offers and linked individual clinician data from on-call records from 15 transplant centers to national transplant registration information. They examined how donor kidney quality affects acceptance rates, as measured by kidney donor profile indexes and other factors. Roughly, clinicians are less likely to accept low-quality kidney offers, but researchers found that the extent to which kidney quality affects decisions differs between clinicians and clinicians.
“Our interdisciplinary research team brings extensive research experience and insights that are essential to our work,” says Green. “Two of our colleagues, Jesse Sheld and Darren Stewart, have led innovative research for many years and have advanced the field of transplant medicine, and Glenn Dutcher offers an innovative approach to the economic aspects of our research. Our work is not possible without this unique combination of our disciplines.”
Looking ahead
Future research by the team explores why variation occurs between clinicians that may affect processes and policies. One potential outcome of the findings of the study is that transplant centers can reflect decision-making practices.
“The transplant center can use our findings to consider the root causes of the variation we found and determine whether there is a way to reduce those variations,” Green said. “This is especially important when evidence suggests that conservative acceptance practices can put a risk to the success of the implant and the health of the patient.”
Interventions at the clinical level include the implementation of evidence-based clinical decision support tools in the allocation process, and the development of tools that demonstrate the association between clinician organ acceptance patterns and patient outcomes before and after implantation.
“When healthcare delivery varies, there are often opportunities for improvement,” Scold says. “In this context, many lives of patients across the country rest on complex systems. Our study provides important insights into opportunities for improvement that may directly affect the increased transplantation opportunities and duration and quality of life in end-stage renal disease patients.”
As a key consequence, the study recommended that policymakers can take into account current variations in decision-making processes within and within transplant centers when designing interventions and allocation mechanisms.
Senior author Stewart, Associate Director of Registry Research at the Center for Surgical and Transplant Applications at NYU Langone Health, pointed out the timeliness of this series of studies. “Now that kidneys are offering about a fifth of them to transplant hospitals as 'open offers', insights into central and physician-specific decision-making are increasingly relevant. This will allow the surgeon to receive the kidneys using discretion to determine the most clinically appropriate patient,” Stewart said. “This represents a 10x increase in open offers, a response to the recent expansion of donor pools.”
The study will help leaders understand how potential policies affect decision-making, Daacher said. “Policies at different levels can have intentional and unintended consequences,” he said. “These unintended consequences can be positive or negative.”
General Productivity Themes
Applied microeconomicists and associate professors Faculty of Economics in Berg Business of CollegeDutcher answers questions about creativity and innovation, personal economics, business economics, remote work, game theory, health economics, and behavioral economics using experiments, research, observational data, and theory. Dutch's expertise in risk preferences and decision-making processes provides important insight into clinician selection, and therefore, research on transplant decisions fits within this broad scope for productivity questions built into the work.
“As an economist, I want to understand how individuals within an organization make decisions, especially when those decisions affect productivity,” he said. “Whether you're looking at creativity, remote work, health economics, or not, when you look at the big chains running through my research, my work is about productivity.”
He, like other members of the research team, is driven by discovering solutions to the real-world challenges faced by people and organizations, and in this work in particular, can dramatically improve people's quality of life and longevity.
