RESUMO

This study describes patient social networks within a new hemodialysis clinic and models the association between social network participation and kidney transplantation. Survey and observational data collected between August 2012 and February 2015 were used to observe the formation of a social network of 46 hemodialysis patients in a newly opened clinic. Thirty-two (70%) patients formed a social network, discussing health (59%) and transplantation (44%) with other patients. While transplant-eligible women participated in the network less often than men (56% vs. 90%, p = 0.02), women who participated discussed their health more often than men (90% vs. 45.5%, p = 0.02). Patients in the social network completed a median of two steps toward transplantation compared with a median of 0 for socially isolated patients (p = 0.003). Patients also completed more steps if network members were closely connected (ß = 2.23, 95% confidence interval [CI] 0.16-4.29, p = 0.03) and if network members themselves completed more steps (ß = 2.84, 95% CI 0.11-5.57, p = 0.04). The hemodialysis clinic patient social network had a net positive effect on completion of transplant steps, and patients who interacted with each other completed a similar number of steps.

RESUMO

Recommendations from the 2014 Consensus Conference on Best Practices in Living Kidney Donation reflect increasing attention to overcoming barriers to donation as a means of expanding access to living donor kidney transplantation. "High priority" initiatives include empowering transplant candidates and their loved ones in their search for a living kidney donor. Transplant programs are assuming an unprecedented role as facilitators of patients' solicitation for donors, and nonprofits are promoting living kidney donation (LKD) in the community. New strategies to promote LKD incorporate "nonargumentative" forms of influence (i.e. approaches to shaping behavior that do not attempt to persuade through reason) such as appeals to emotion, messenger effects and social norms. These approaches have raised ethical concerns in other settings but have received little attention in the transplantation literature despite their increasing relevance. Previous work on using nonargumentative influence to shape patient behavior has highlighted implications for (1) the relationship between influencer and influenced and (2) patient autonomy. We argue that using nonargumentative influence to promote LKD is a promising strategy that can be compatible with ethical standards. We also outline potential concerns and solutions to be implemented in practice.

RESUMO

Donation after cardiac death is an important source of transplantable organs, but evidence suggests donor warm ischemia contributes to inferior outcomes. Attempts to predict recipient outcome using donor hemodynamic measurements have not yielded statistically significant results. We evaluated novel measures of donor hemodynamics as predictors of delayed graft function and graft failure in a cohort of 1050 kidneys from 566 donors. Hemodynamics were described using regression line slopes, areas under the curve, and time beyond thresholds for systolic blood pressure, oxygen saturation, and shock index (heart rate divided by systolic blood pressure). A logistic generalized estimation equation model showed that area under the curve for systolic blood pressure was predictive of delayed graft function (above median: odds ratio 1.42, 95% confidence interval [CI] 1.06-1.90). Multivariable Cox regression demonstrated that slope of oxygen saturation during the first 10 minutes after extubation was associated with graft failure (below median: hazard ratio 1.30, 95% CI 1.03-1.64), with 5-year graft survival of 70.0% (95%CI 64.5%-74.8%) for donors above the median versus 61.4% (95%CI 55.5%-66.7%) for those below the median. Among older donors, increased shock index slope was associated with increased hazard of graft failure. Validation of these findings is necessary to determine the utility of characterizing donor warm ischemia to predict recipient outcome.

RESUMO

Organ transplantation is an acceptable option for human immunodeficiency virus (HIV)-infected patients with end-stage kidney or liver disease. With worse outcomes on the waitlist, HIV-infected patients may actually be disproportionately affected by the organ shortage in the United States. One potential solution is the use of HIV-infected deceased donors (HIVDD), recently legalized by the HIV Organ Policy Equity (HOPE) Act. This is the first analysis of patient-specific data from potential HIVDD, retrospectively examining charts of HIV-infected patients dying in care at six HIV clinics in Philadelphia, Pennsylvania from January 1, 2009 to June 30, 2014. Our data suggest that there are four to five potential HIVDD dying in Philadelphia annually who might yield two to three kidneys and three to five livers for transplant. Extrapolated nationally, this would approximate 356 potential HIVDD yielding 192 kidneys and 247 livers annually. However, several donor risk indices raise concerns about the quality of kidneys that could be recovered from HIVDD as a result of older donor age and comorbidities. On the other hand, livers from these potential HIVDD are of similar quality to HIV-negative donors dying locally, although there is a high prevalence of positive hepatitis C antibody.

RESUMO

Over the past two decades, live kidney donation by older individuals (≥55 years) has become more common. Given the strong associations of older age with cardiovascular disease (CVD), nephrectomy could make older donors vulnerable to death and cardiovascular events. We performed a cohort study among older live kidney donors who were matched to healthy older individuals in the Health and Retirement Study. The primary outcome was mortality ascertained through national death registries. Secondary outcomes ascertained among pairs with Medicare coverage included death or CVD ascertained through Medicare claims data. During the period from 1996 to 2006, there were 5717 older donors in the United States. We matched 3368 donors 1:1 to older healthy nondonors. Among donors and matched pairs, the mean age was 59 years; 41% were male and 7% were black race. In median follow-up of 7.8 years, mortality was not different between donors and matched pairs (p = 0.21). Among donors with Medicare, the combined outcome of death/CVD (p = 0.70) was also not different between donors and nondonors. In summary, carefully selected older kidney donors do not face a higher risk of death or CVD. These findings should be provided to older individuals considering live kidney donation.

RESUMO

In the setting of organ scarcity, the ethics of multi-organ transplantation (MOT) deserve new examination. MOT offers substantial benefits to certain recipients, including avoiding serial surgeries. However, MOT candidates in the United States commonly receive priority for their nonprimary organ over many individuals who need that organ, which may undermine equity. The absence of standard criteria for MOT eligibility also enables large and unfair regional variation in MOT, such as simultaneous liver-kidney transplantation. Unfortunately, MOT may also undermine utility (optimal patient and graft survival) in circumstances where providing multiple organs to one person fails to achieve the greater collective benefit attained by providing transplants to multiple people. Policy reforms should include the adoption of minimal clinical criteria for MOT candidacy with the attendant goal of decreasing regional variation in MOT. In the future, these minimal criteria can be revised to accommodate new research about which patients derive the most benefit from MOT. Incentives to perform MOT should also be reduced, such as by including MOT outcomes in center-specific reports. These reforms run the risk that the transplant community could be perceived as abandoning MOT candidates, but offer an opportunity to align transplant practice and ethical principles.

RESUMO

Early rehospitalization after kidney transplantation (KT) is common and may predict future adverse outcomes. Previous studies using claims data have been limited in identifying preventable rehospitalizations. We assembled a cohort of 753 adults at our institution undergoing KT from January 1, 2003 to December 31, 2007. Two physicians independently reviewed medical records of 237 patients (32%) with early rehospitalization and identified (1) primary reason for and (2) preventability of rehospitalization. Mortality and graft failure were ascertained through linkage to the Scientific Registry of Transplant Recipients. Leading reasons for rehospitalization included surgical complications (15%), rejection (14%), volume shifts (11%) and systemic and surgical wound infections (11% and 2.5%). Reviewer agreement on primary reason (85% of cases) was strong (kappa = 0.78). Only 19 rehospitalizations (8%) met preventability criteria. Using logistic regression, weekend discharge (odds ratio [OR] 1.59, p = 0.01), waitlist time (OR 1.10, p = 0.04) and longer initial length of stay (OR 1.42, p = 0.03) were associated with early rehospitalization. Using Cox regression, early rehospitalization was associated with mortality (hazard ratio [HR] 1.55; p = 0.03) but not graft loss (HR 1.33; p = 0.09). Early rehospitalization has diverse causes and presents challenges as a quality metric after KT. These results should be validated prospectively at multiple centers to identify vulnerable patients and modifiable processes-of-care.
