Accountable care organizations and spending for patients undergoing long-term dialysis.
This study analyzed Medicare data to examine time trends in long-term dialysis beneficiary alignment to Accountable Care Organizations (ACOs) and differences in spending for those who were Accountable Care Organization aligned versus nonaligned. Beneficiaries on long-term dialysis between 2009 and 2016 were identified using a 20% random sample of Medicare beneficiaries. Trends in alignment to an ACO alignment were compared with alignment of the general Medicare population. The cohort included 135,152 beneficiaries during the study period. Alignment to an ACO of long-term dialysis beneficiaries increased from 6% to 23% from 2012 to 2016. In the time series analysis, ACO spending was $143 less per beneficiary-quarter than spending for non-aligned beneficiaries. This savings was limited to care by a primary care physician.

Arteriovenous fistula placement, maturation, and patency loss in older patients initiating hemodialysis.
The current clinical guidelines for vascular access do not have specific recommendations for older hemodialysis patients. This retrospective cohort study aimed to determine the association of age with arteriovenous fistula (AVF) placement, maturation, and primary and secondary patency loss among older hemodialysis recipients. The authors conclude that the likelihood of AVF maturation is an important consideration for vascular access planning.

Racial/ethnic inequities in access to high-quality dialysis treatment in Chicago: does neighborhood racial/ethnic composition matter?
Investigators examined whether neighborhood racial composition contributes to racial/ethnic inequities in access to high-quality dialysis care in Chicago. Data from the United States Renal Data System was merged with the ESRD Quality Incentive Program file and the American Community Survey (2005-2009) for facility and neighborhood characteristics. The investigators concluded that expanding opportunities for Blacks and Hispanics to gain access to racially integrated and minority neighborhoods may help alleviate racial/ethnic inequities in access to quality care among kidney disease patients.

National trends in the association of race and ethnicity with predialysis nephrology care in the United States From 2005 to 2015.
Predialysis nephrology care is associated with better survival among patients with end-stage kidney disease. The purpose of this study was to examine national trends in racial/ethnic disparities in receipt of predialysis nephrology care at least 1 year before dialysis initiation in the United States from 2005 to 2015. The study findings suggested that national strategies to address racial/ethnic disparities in predialysis nephrology care are needed.

Comparative effectiveness of high-dose versus standard-dose influenza vaccine among patients receiving maintenance hemodialysis.
This study compared outcomes of routine dialysis patients who received either the standard dose vaccine (SDV) for influenza or a high-dose vaccine (HDV). Out of 22,215 influenza patient-seasons among adults 65 years and older, 97.4% received SDV and 2.6% received HDV. There did not seem to be any additional protection provided by the HDV for all-cause mortality or influenza-related outcomes.

The perfect storm: stakeholder perspectives on factors contributing to hospital admissions for patients undergoing maintenance hemodialysis.
This study examined reasons why end stage renal disease (ESRD) patients undergoing hemodialysis experience frequent complications and hospitalizations. Interviews and focus groups were conducted with 21 patients living with ESRD, 10 caregivers, and three focus groups with health care professionals. There were four main themes that came out of the discussions: graft site/catheter/access issues, low resistance, breathing problems, and “The perfect storm”. The goal of these interviews were to promote more research to improve transitional care and care delivery for hemodialysis patients.

Long-term outcomes among Medicare patients readmitted in the first year of hemodialysis: a retrospective cohort study.
This retrospective cohort study examined long-term outcomes among Medicare patients with end-stage renal disease (ESRD) during the first year of hemodialysis. The goal was to determine hospital readmission patterns in the first year of dialysis and outcomes in the second year. Data from the United States Renal Data System (USRDS) was used and readmission patterns were summarized as either no readmission within 30 days, at least one admission, but not within 30 days, and admission with at least one readmission within 30 days. About half of all patients did not get readmitted (51%), but 18.5% were readmitted within 30 days, and 30.5% were admitted but not within 30 days. Those who were readmitted within 30 days had the highest long-term risk of mortality, hospitalization and lower likelihood of kidney transplantation compared to patients who were not admitted or readmitted.

Association of scheduled vs emergency-only dialysis with health outcomes and costs in undocumented immigrants with end-stage renal disease.
This paper discusses costs and mortality associated with undocumented immigrants with end-stage renal disease (ESRD). If the patient has insurance, the costs and mortality rates are much lower than those who receive emergency-only dialysis.

Editor's choice - comparison of outcomes after open surgical and endovascular lower extremity revascularisation among end stage renal disease patients on dialysis.
This study compared outcomes of different revascularization surgeries among end stage renal disease (ESRD) patients with peripheral arterial disease (PAD). There is a high risk of complications for this surgery. Outcomes of endovascular revascularization (ER) and open surgical revascularisation (OSR) were compared. Outcomes measured included mortality and major amputation. There is a lower mortality risk for ER versus OSR. OSR has better 30-day limb salvage although there are similar long-term outcomes.
