Association of race and ethnicity with live donor kidney transplantation in the United States from 1995 to 2014.
This study estimated changes over time in racial/ethnic disparities in live donor kidney transplantation (LDKT) in the United States, accounting for differences in death and deceased donor kidney transplantation. Among adult first-time kidney transplantation candidates in the United States who were added to the deceased donor kidney transplantation waiting list between 1995 and 2014, disparities in the receipt of live donor kidney transplantation increased from 1995-1999 to 2010-2014.

Persistent regional and racial disparities in nondirected living kidney donation.
Nondirected living donors (NDLDs) are an important and growing source of kidneys to help reduce the organ shortage. The authors of this study hypothesized that the initial geographic clustering and racial disparities may have improved due to an increase in NDLDs. The authors found that despite the increased number of NDLDs, racial disparities have worsened and the center-level distribution of NDLD transplants has narrowed in recent years.

The national landscape of living kidney donor follow-up in the United States.
The purpose of this study was to understand the impact of the 2013 policy the Organ Procurement and Transplantation Network/United Network for Organ Sharing issued. The policy required that transplant centers collect data on living kidney donors (LKDs) at 6 months, 1 year, and 2 years postdonation, with policy-defined thresholds for the proportion of complete living donor follow-up data submitted in a timely manner (60 days before or after the expected visit date).

Influence of kidney offer acceptance behavior on metrics of allocation efficiency.
This study investigated associations of deceased donor kidney offer acceptance with likelihood of the kidney being discarded, cold ischemia time at transplant (CIT), and likelihood of the kidney being exported outside the donation service area (DSA). The authors suggest that improving lower-than-expected offer acceptance would likely reduce discards, CIT, and exports.

A kidney graft survival calculator that accounts for mismatches in age, sex, HLA, and body size.
Models were adjusted for year of transplant and donor and recipient characteristics, with particular attention to mismatches in age, sex, human leukocyte antigens (HLA), body size, and weight. These models were used to create a calculator of estimated graft survival for living donors. This calculator provides useful information to donors, candidates, and physicians of estimated outcomes and potentially in allowing candidates to choose among several living donors.

Reexamining the association of body mass index with overall survival outcomes after liver transplantation.
The purpose of this study is to identify the range of body mass index (BMI) at liver transplantation (LT) associated with the lowest risks of posttransplant mortality by Model of End Stage Liver Disease (MELD) category. It concluded that obesity in LT patients is not necessarily associated with higher posttransplantation mortality and highlighted the importance of the interaction between BMI and MELD category to determine their survival likelihood.

Communicating About Choices in Transplantation (COACH).
This article presents pilot results of the behavioral communication intervention program, Communicating about Choices in Transplantation (COACH), designed to improve transplant candidates' communication about transplantation. The authors indicate that results provided preliminary support for the program's impact. Moreover, participant evaluations of the COACH were overwhelmingly positive. They noted that a more definitive program evaluation with a larger, more diverse sample is currently underway.

Kidney exchange to overcome financial barriers to kidney transplantation.
Organ shortage is the major limitation to kidney transplantation in the developed world. This proposal leverages the cost savings achieved through earlier transplantation over dialysis to fund the cost of kidney exchange between developed-world patient-donor pairs with immunological barriers and developing-world patient-donor pairs with financial barriers.

A qualitative exploration of the informed consent process in hematopoietic cell transplantation clinical research and opportunities for improvement.
This study found that providers understand informed consent to be a collaborative process requiring engagement and participation of providers, patients and caregivers. 'Markers of success' were identified including cognitive, affective and procedural markers focusing on patient understanding and comfort with the decision to participate. Opportunities for innovating the process included use of decision aids and tablet-based technology, and better use of patient portals.

Survival analyses and prognosis of plasma-cell myeloma and plasmacytoma-like posttransplantation lymphoproliferative disorders.
Multiple myeloma/plasmacytoma-like posttransplantation lymphoproliferative disorder (PTLD-MM) is a rare complication of solid organ transplantation. Case series have shown variable outcomes, and survival data in the modern era are lacking. This study found that age at diagnosis, elevated creatinine, and white race were associated with inferior survival in patients with PTLD-MM.

The role of extended criteria donors in liver transplantation for nonalcoholic steatohepatitis.
The authors' objective was to determine the use of extended criteria donors (ECD) in patients with nonalcoholic steatohepatitis undergoing liver transplantation to stimulate a liver-specific predictive model for ECD use. They found that ECDs in nonalcoholic steatohepatitis were associated with similar overall survival but increased risk of graft failure. The authors concluded that creation of an easily calculated, liver-specific model similar to the Kidney Donor Profile Index may help risk stratify patients and improve organ allocation.

Applying the WHO conceptual framework for the International Classification for Patient Safety to a surgical population.
The researchers aimed to test the applicability of the International Classification for Patient Safety to a surgical population by developing a codebook for future use by researchers. They found that the most common severity classification was 'reportable circumstance' and that the most common incident type was 'resources/organizational management.' They noted that several aspects of surgical care were encompassed by more than one classification, including operating room scheduling, delays in care, trainee-related incidents, interruptions, and handoffs. They concluded that a framework for patient safety can be applied to facilitate the organization and analysis of surgical safety data.

Living kidney donors' information needs and preferences.
The purpose of this study was to assess donors' perceptions of the information provided while considering living donation. The study revealed limited usefulness of certain CMS-mandated topics and a desire for additional information about donation. Efforts to standardize the informed consent process should incorporate donors' perspectives as to the specific topics, quantity of information, and the mode of communication found most useful when considering living donation.

Identifying unmet informational needs in the inpatient setting to increase patient and caregiver engagement in the context of pediatric hematopoietic stem cell transplantation.
The researchers conducted field observations and semi-structured interviews of pediatric hematopoietic stem cell transplantation (HSCT) caregivers and patients to identify informational challenges in the inpatient hospital setting. Theyn concluded that pediatric HSCT caregivers and patients have multiple informational needs that could be met with a health information technology system that integrates data from several sources, including electronic health records. Meeting these needs could reduce patients' and caregivers' anxiety surrounding the care process.

Organ donation video messaging in motor vehicle offices: results of a randomized trial.
Since nearly all registered organ donors in the United States signed up via a driver's license transaction, motor vehicle (MV) offices represent an important venue for organ donation education. The researchers evaluated the impact of organ donation video messaging in MV offices. There was a relatively low uptake of the video intervention by customers that most likely contributed to the negative trial finding.

Historical matching strategies in kidney paired donation: the 7-year evolution of a web-based virtual matching system.
Failure to convert computer-identified possible kidney paired donation (KPD) exchanges into transplants has prohibited KPD from reaching its full potential. This study analyzes the progress of exchanges in moving from "offers" to completed transplants. The "offer" and 1-way success rates were 21.9 and 15.5 percent, respectively. Three reasons for failure were found that could be prospectively prevented by changes in protocol or software.

Planning for uncertainty and fallbacks can increase the number of transplants in a kidney-paired donation program.
The researchers outlined and examined, through example and by simulation, four schemes for selecting potential matches in a realistic model of a kidney-paired donation system. Their proposed schemes take account of probabilities that chosen transplants may not be completed as well as allowing for contingency plans when the optimal solution fails.
