Fragmentation of care as a barrier to optimal ESKD management

Caring for patients with end-stage kidney disease (ESKD) in the United States is challenging, due in part to the complex epidemiology of the disease's progression as well as the ways in which care is delivered. As CKD progresses toward ESKD, the number of comorbidities increases and care involves multiple healthcare providers from multiple subspecialties. This occurs in the context of a fragmented US healthcare delivery system that is traditionally siloed by provider specialty, organization, as well as systems of payment and administration. This article describes the role of care fragmentation in the delivery of optimal ESKD care and identifies research gaps in the evidence across the continuum of care. We then consider the impact of care fragmentation on ESKD care from the patient and health system perspectives and explore opportunities for system-level interventions aimed at improving care for patients with ESKD.     

Associations of perceived information adequacy and knowledge with pursuit of live donor kidney transplants and living donor inquiries among African American transplant candidates

We studied associations between perceived adequacy of live donor kidney transplant (LDKT) information or knowledge with pursuit of LDKT or receipt of live donor inquiries among 300 African American kidney transplant candidates. Participants reported via questionnaire how informed or knowledgeable they felt regarding LDKT. Participants also reported their pursuit of LDKT, categorized as “low” (no discussion with family or friends about LDKT and no identified donor), “intermediate” (discussed LDKT with family but no identified donor) or “high” (discussed LDKT with family and identified a potential donor). We reviewed participants' electronic health records to identify potential donors' transplant center inquiries on participants' behalves. A minority of participants reported they felt “very” or “extremely” well informed about LDKT (39%) or had “a great deal” of LDKT knowledge (38%). Participants perceiving themselves as “very” or “extremely” (vs “not” or “slightly”) well informed about LDKT had statistically significantly greater odds of intermediate or high (vs low) pursuit of LDKT (odds ratio [95% confidence interval] 2.71 [1.02-7.17]). Perceived LDKT knowledge was not associated with pursuit of LDKT. Neither perceived information adequacy nor knowledge was associated with living donor inquiries. Efforts to better understand the role of education in the pursuit of LDKT among African American transplant candidates are needed.     

Trust in American Medicine: A Call to Action for Health Care Professionals

Medical mistrust has a well-documented harmful impact on a range of patients’ health behaviors and outcomes. It can have such egregious downstream effects on so many aspects of medicine—from clinical trial participation to health care use, timely screening, organ donation, and treatment adherence—that it is sometimes described as one of the social determinants of health. In the article “Trust, Risk, and Race in American Medicine,” Laura Specker Sullivan makes the compelling case that trust is essential to building a therapeutic alliance in which effective, high-quality health care can be delivered and received. As a complement to her suggestion that health care providers take an active role in mitigating mistrust by demonstrating “not only their capacity to be honest and forthright but also their ability to respond to the potential truster's needs,” we recommend that key health care professionals commit to five actions.     

Transplant social worker and donor financial assistance to increase living donor kidney transplants among African Americans: The TALKS Study,a randomized comparative effectiveness trial

Lack of donors hinders living donor kidney transplantation (LDKT) for African Americans. We studied the effectiveness of a transplant social worker intervention (TALK SWI) alone or paired with living donor financial assistance to activate African Americans’ potential living kidney donors. African Americans (N = 300) on the transplant waiting list were randomly assigned to usual care; TALK SWI; or TALK SWI plus Living Donor Financial Assistance. We quantified differences in live kidney donor activation (composite rate of live donor inquiries, completed new live donor evaluations, or live kidney donation) after 12 months. Participants’ mean age was 52 years, 56% were male, and 43% had annual household income less than $40,000. Most previously pursued LDKT. Participants were highly satisfied with TALK social workers, but they rarely utilized Financial Assistance. After 12 months, few (n = 39, 13%) participants had a new donor activation event (35 [12%] new donor inquiries; 17 [6%] new donor evaluations; 4 [1%] LDKT). There were no group differences in donor activation events (subdistribution hazard ratio [95% CI]: 1.09 [0.51–2.30] for TALK SWI and 0.92 [0.42–2.02] for TALK SWI plus Financial Assistance compared to Usual Care, p = 91). Alternative interventions to increase LDKT for African Americans on the waiting list may be needed. Trial registration: ClinicalTrials.gov (NCT02369354).     

Masculinity,Medical Mistrust,and Preventive Health Services Delays Among Community-Dwelling African-American Men

BACKGROUND  

The contribution of masculinity to men’s healthcare use has gained increased public health interest; however, few studies have examined this association among African-American men, who delay healthcare more often, define masculinity differently, and report higher levels of medical mistrust than non-Hispanic White men.     

CKD of Uncertain Etiology: A Systematic Review

Background and objectives

Epidemics of CKD of uncertain etiology (CKDu) are emerging around the world. Highlighting common risk factors for CKD of uncertain etiology across various regions and populations may be important for health policy and public health responses.

Design, setting, participants, & measurements

We searched PubMed, Embase, Scopus and Web of Science databases to identify published studies on CKDu. The search was generated in January of 2015; no language or date limits were used. We used a vote-counting method to evaluate exposures across all studies.

Results

We identified 1607 articles, of which 26 met inclusion criteria. Eighteen (69%) were conducted in known CKDu–endemic countries: Sri Lanka (38%), Nicaragua (19%), and El Salvador (12%). The other studies were from India, Japan, Australia, Mexico, Sweden, Tunisia, Tanzania, and the United States. Heavy metals, heat stress, and dietary exposures were reported across all geographic regions. In south Asia, family history, agrochemical use, and heavy metal exposures were reported most frequently, whereas altitude and temperature were reported only in studies from Central America. Across all regions, CKDu was most frequently associated with a family history of CKDu, agricultural occupation, men, middle age, snake bite, and heavy metal exposure.

Conclusions

Studies examining etiologies of CKDu have reported many exposures that are heterogeneous and vary by region. To identify etiologies of CKDu, designing consistent and comparative multisite studies across high-risk populations may help elucidate the importance of region–specific versus global risk factors.
