What are the main findings of the study?
In this retrospective study, patients with hospital-acquired acute kidney injury (HA-AKI) who were not referred (nrHA-AKI) or late referred (lrHA-AKI) to the nephrologist represented an important percentage of the hospitalized population. Furthermore, these conditions were associated with patients’ in-hospital mortality, less recovery of renal function, and need for renal replacement therapy (RRT).
Were any of the findings unexpected?
The potential reasons why 22.3% and 58.3% of the patients hospitalized were either not referred or referred to the nephrologist late, respectively, are multiple. One explanation may be the definition of AKI, which is neither uniformly known nor accepted in the non-nephrologic community. Serum creatinine level alone is a relatively late and imprecise biomarker of kidney dysfunction, which may also lead to delayed referral. Finally, patients with AKI had more comorbidities, increasing the complexity of medical care and possibly increasing the time required to make treatment decisions.
What should clinicians and patients take away from this study?
Hospital-acquired AKI is frequent, and compared with erHA-AKI, nrHA-AKI and lrHA-AKI are significantly associated with worse renal outcome and low in-hospital patient survival. An episode of HA-AKI requires prompt awareness and nephrologist referral to lower in-hospital morbidity and mortality.
What recommendations do you have for nephrology health care providers as a result of your study?
In-hospital primary care physicians should not underestimate renal risk factors known to be responsible for HA-AKI, especially if these risk factors cumulate (e.g., old age with high basal SCr, emergency, radiologic procedures with iodine radiocontrast, nephrotoxic drugs). When caring for patients at risk for AKI (e.g., those with multiple myeloma, diabetes mellitus, hypertension) or patients with mild to moderate CKD (i.e., 30 to 60 ml/min per 1.73 m2), awareness of AKI status is dependent on understanding of individual risk, which in turn depends on general knowledge of AKI.
Abstract:
Summary Background and objectives Despite modern treatment, the case fatality rate of hospital-acquired acute kidney injury (HA-AKI) is still high.
We retrospectively described the prevalence and the outcome of HA-AKI without nephrology referral (nrHA-AKI) and late referred HA-AKI patients to nephrologists (lrHA-AKI) compared with early referral patients (erHA-AKI) with respect to renal function recovery, renal replacement therapy (RRT) requirement, and in-hospital mortality of HA-AKI.
Design, setting, participants, & measurements Noncritically ill patients admitted to the tertiary care academic center of Lausanne, Switzerland, between 2004 and 2008 in the medical and surgical services were included. Acute kidney injury was defined using the Acute Kidney Injury Network (AKIN) classification.
Results During 5 years, 4296 patients (4.12% of admissions) experienced 4727 episodes of HA-AKI during their hospital stay. The mean ± SD age of the patients was 61 ± 15 years with a 55% male predominance. There were 958 patients with nrHA-AKI (22.3%) and 2504 patients with lrHA-AKI (58.3%). RRT was required in 31% of the patients with lrHA-AKI compared with 24% of the patients with erHA-AKI. In the multiple risk factor analysis, compared with erHA-AKI, nrHA-AKI and lrHA-AKI were significantly associated with worse renal outcome and higher in-hospital mortality.
Conclusions These data suggest that HA-AKI is frequent and the patients with nrHA-AKI or lrHA-AKI are at increased risk for in-hospital morbidity and mortality.
Home Dialysis Summit Recommends Policy Changes to Increase Home Dialysis Usage
WASHINGTON, April 25, 2012 /PRNewswire -- On the heels of the first National Summit on Home Dialysis Policy, Summit organizers released a report reflecting the views of the delegates -- leaders in the kidney disease patient, clinician, facility and industry communities -- on federal policy steps to improve utilization of home dialysis for patients who can benefit from this often advantageous form of treatment. Many of the organizers also announced they have formed a new alliance, called the Alliance for Home Dialysis, to advance the recommendations identified at the Summit.
The Summit's "Report of the Delegates" highlights key findings from a March 29th meeting in Washington, DC where experts probed why, despite widely accepted and well-documented benefits of home dialysis -- improved outcomes, enhanced patient satisfaction, improved quality of life, and lower costs-- fewer than ten percent of the more than 390,000 current U.S. dialysis patients receive treatment at home. Current rates of home dialysis utilization reflect a steep decline from the 1970s, when almost 40% of U.S. dialysis patients were treated in-home.
Specifically, delegates found that policymakers should work with stakeholders in the dialysis community to confront three areas:
Accessibility: Patients and clinicians face array of hurdles in education, training, and infrastructure that hinder equalized access to home dialysis.
Accountability: Utilization of home dialysis can be improved through measures within government programs that are designed to recognize and support excellence in the delivery of home dialysis services.
Aligning Incentives: Reimbursement policies, regulation of new technologies and other policy incentives can be realigned to better support federal policy goals of expanding access to home dialysis.
The Report includes 15 recommendations to serve these goals, including that federal policymakers should:
Maintain parity for home and in-center dialysis in Medicare reimbursement;
Support home dialysis mentoring programs, particularly those that use existing patients as mentors; and
Align federal and state regulatory requirements for home therapies, such as revising the Centers for Medicare and Medicaid Services Conditions for Coverage requirements, to reflect differences in home and in-center dialysis.
Summit supporters will begin work through the new Alliance to dialogue with federal policymakers and advance policy improvements in the three consensus areas that emerged at the Summit.

National Kidney Foundation's Top 10 Things Every Dialysis Patient Should Know.
You have treatment choices. Options exist for how, where and when you dialyze. Dialysis can be done in a hospital, in a dialysis unit that is not part of a hospital, or at home. You and your doctor will decide which place is best, based on your medical condition and your wishes. There are different types of dialysis - peritoneal and hemodialysis. Work with your health care team to determine a treatment plan that makes you feel comfortable. Recent studies show that the majority of patients beginning in-center hemodialysis (HD) know very little, if anything, about the option to dialyze at home. Once informed, 40% or more of patients are interested in this treatment option, and yet less than 10% actually begin home dialysis. If you're dissatisfied with the type of dialysis treatment that you're receiving, ask your healthcare team if another type of dialysis treatment would be better.
You can compare in-center dialysis facilities online. Information on over 5,600 US-based dialysis centers is available online through the Medicare website. To help you make choices about your care, you can compare different facilities side-by-side and evaluate each facility based upon clinic characteristics and quality measures. You can search for dialysis facilities by name or geographic proximity. After completing an initial facility comparison to determine which facilities best meet your needs - such as the number of hemodialysis stations at a particular location and whether there are evening shifts available - visit the facilities that you're most interested in. Talk to the staff and other patients, as well as your doctor to ensure that this dialysis facility is a good fit for you.
There are ways to prepare ahead for an emergency. Ask your dialysis facility about their emergency plan in case of a snow storm, fire, power outage or other natural disaster. As back up, make sure you have the names, locations and phone numbers of other dialysis units and hospitals in your area. Since regular community transportation services may not be working in an emergency, be prepared to make other arrangements for getting to dialysis. You may need to contact the police and Emergency Medical Services (EMS) for assistance. If you dialyze at home, make sure you have at least two weeks' worth of unexpired supplies on hand. If you have to miss a dialysis treatment, begin your emergency meal plan.
There is an easy way to transfer patient records between clinics. There is an easy, secure way for your health care team to transfer your treatment records online. In 2009, the Centers for Medicare and Medicaid Services (CMS) created a centralized web-based data collection system called CROWNWeb to help reduce and eliminate patient treatment interruptions. This central system helps to streamline patient care regardless of the reason for changing dialysis centers. For example, if you've been admitted to the hospital, or if you needed to relocate during an emergency evacuation, your doctors and health care team can access up-to-date information about your dialysis so that you continue to receive appropriate care no matter where you are.
You can travel while on dialysis.
Dialysis centers are located in every part of the United States and in many foreign countries. The treatment is standardized, but you need to plan ahead by making an appointment for dialysis at another center before you go. The staff at your center may help you make these appointments.
You can be your own best advocate. Know what key questions to ask your doctor or other healthcare professionals. Take notes so that you can refer back to them later. Partner with your doctor and decide on a treatment plan together. Advocate for yourself and share how you're feeling.
You have many rights. You as a patient have a great deal of control over your treatments. Patients have a bill of rights which includes receiving quality care, counseling about your medical information, and an expectation of privacy.
You also have responsibilities. Once you decide on a course of treatment, it's important to follow the recommendations of your health care team. If you decide to receive in-center dialysis, arrive at dialysis on time so that you can receive the full treatment without delays.
You can receive insurance coverage. If you have end stage renal failure, you are likely eligible for Medicare insurance coverage. Speak with your health care team and social worker for help filling out insurance paperwork.
You may need to follow a special diet. When your kidneys are not working properly, you may not be able to eat everything you like, and you may need to limit how much you drink. Your diet may vary according to the type of dialysis you receive. It is important to speak with a renal dietitian so that you are able to understand what you can and cannot eat based on your full health history.
Dialysis patients can work. Many dialysis patients can go back to work or school after they have gotten used to dialysis. After establishing a dialysis routine, many patients have more energy and find that they are able to time to work around this new schedule. Some patients even find creative ways to work remotely from dialysis with the use of a laptop or cell phone, depending on their field of expertise.
