Accountable care organizations (ACOs) are a newly proposed vehicle for improving or maintaining high-quality patient care while controlling costs. They are meant to achieve the goals of the Medicare Shared Savings Program mandated by the Patient Protection and Affordable Care Act (PPACA) of 2010. ACOs are voluntary groups of hospitals, physicians, and health care teams that provide care for a defined group of Medicare beneficiaries and assume responsibility for providing high-quality care through defined quality measures at a cost below what would have been expected. ⋯ Health care for patients with end-stage renal disease is complex due to multiple patient comorbid conditions, expensive, and often poorly coordinated. Due to the unique needs of patients with end-stage renal disease receiving dialysis, ACOs may be unable to provide the highly specialized quality care these patients require. We discuss the benefits and risks of a renal-focused ACO for dialysis patients, as well as the kidney community's prior experience with an ACO-like demonstration project.

Underlying causes of metabolic alkalosis may be evident from history, evaluation of effective circulatory volume, and measurement of urine chloride concentration. However, identification of causes may be difficult for certain conditions associated with clandestine behaviors, such as surreptitious vomiting, use of drugs or herbal supplements with mineralocorticoid activity, abuse of laxatives or diuretics, and long-term use of alkalis. ⋯ The cause of the patient's metabolic alkalosis eventually was linked to surreptitious ingestion of baking soda. This case highlights the necessity of a high index of suspicion for the diverse clandestine behaviors that can cause metabolic alkalosis and the usefulness of urine pH and anion gap in its differential diagnosis.

Comparative Study
Long-term risk of CKD in children surviving episodes of acute kidney injury in the intensive care unit: a prospective cohort study.
The development of standardized acute kidney injury (AKI) definitions has allowed for a better understanding of AKI epidemiology, but the long-term renal outcomes of AKI in the pediatric critical care setting have not been well established. This study was designed to: (1) determine the incidence of chronic kidney disease (CKD) in children 1-3 years after an episode of AKI at a tertiary-care pediatric intensive care unit (ICU), (2) identify the proportion of patients at risk of CKD, and (3) compare ICU admission characteristics in those with and without CKD. ⋯ In tertiary-care pediatric ICU patients, ∼10% develop CKD 1-3 years after AKI. The burden of CKD in this population may be higher with further follow-up because several patients were identified as being at risk of CKD. Regardless of the severity of AKI, all pediatric ICU patients should be monitored regularly for long-term kidney damage.

The impact of the intensity of renal replacement therapy on outcomes in patients with acute kidney injury has been studied intensively during the past decade. In this review, we consider the concept of dose of renal replacement therapy in acute kidney injury and summarize the recent clinical trials addressing this topic. Although several single-center trials suggest that more intensive therapy is associated with improved outcomes, 2 large multicenter randomized trials do not find a benefit with higher doses of therapy. Based on these studies, we provide recommendations for the delivered intensity of renal replacement therapy in acute kidney injury.

In the nontransplant setting, acute kidney injury (AKI) may lead to chronic kidney disease (CKD) and end-stage renal disease, but the epidemiology of AKI in transplant recipients has not been characterized. The purpose of this study was to determine the incidence and consequences of AKI in kidney transplant recipients outside the peritransplant period and unrelated to acute rejection. ⋯ We conclude that AKI is increasingly common and associated with transplant failure and death. Later CKD stage increases the risk of AKI, but AKI-associated risks of transplant failure were greater in those with higher levels of kidney function (earlier CKD stage).
