Background and objectives: While many patients with end-stage renal disease (ESRD) have impaired physical and psychologic well-being, less is known about these health domains in patients with advanced chronic kidney disease (CKD). The authors sought to compare symptoms, depression, and quality of life in patients with ESRD and those with CKD. Design, setting, participants, & measurements: Patients with ESRD and subjects with advanced CKD were enrolled. Patients’ symptoms, depression, and quality of life were assessed using the Dialysis Symptom Index (DSI), Patient Health Questionnaire-9 (PHQ-9), and Short Form 36 (SF-36), respectively, and these health domains were compared between patient groups. Results: Ninety patients with ESRD and 87 with CKD were enrolled. There were no differences in the overall number of symptoms or in the total DSI symptom-severity score. Median scores on the PHQ-9 were similar, as was the proportion of patients with PHQ-9 scores >9. SF-36 Physical Component Summary scores were comparable, as were SF-36 Mental Component Summary scores. Conclusions: The burden of symptoms, prevalence of depression, and low quality of life are comparable in patients with ESRD and advanced CKD. Given the widely recognized impairments in these domains in ESRD, findings of this study underscore the substantial decrements in the physical and psychologic well-being of patients with CKD.

Recurrent AKI is common among patients after hospitalized AKI and is associated with progressive CKD. In this study, we identified clinical risk factors for recurrent AKI present during index AKI hospitalizations that occurred between 2003 and 2010 using a regional Veterans Administration database in the United States. AKI was defined as a 0.3 mg/dl or 50% increase from a baseline creatinine measure. The primary outcome was hospitalization with recurrent AKI within 12 months of discharge from the index hospitalization. Time to recurrent AKI was examined using Cox regression analysis, and sensitivity analyses were performed using a competing risk approach. Among 11,683 qualifying AKI hospitalizations, 2954 patients (25%) were hospitalized with recurrent AKI within 12 months of discharge. Median time to recurrent AKI within 12 months was 64 (interquartile range 19–167) days. In addition to known demographic and comorbid risk factors for AKI, patients with longer AKI duration and those whose discharge diagnosis at index AKI hospitalization included congestive heart failure (primary diagnosis), decompensated advanced liver disease, cancer with or without chemotherapy, acute coronary syndrome, or volume depletion, were at highest risk for being hospitalized with recurrent AKI. Risk factors identified were similar when a competing risk model for death was applied. In conclusion, several inpatient conditions associated with AKI may increase the risk for recurrent AKI. These findings should facilitate risk stratification, guide appropriate patient referral after AKI, and help generate potential risk reduction strategies. Efforts to identify modifiable factors to prevent recurrent AKI in these patients are warranted.

Background: Older adults with advanced CKD have significant pain, other symptoms, and disability. To help ensure that care is consistent with patients’ values, nephrology providers should understand their patients’ priorities when they make clinical recommendations. Methods: Patients aged ≥60 years with advanced (stage 4 or 5) non–dialysis-dependent CKD receiving care at a CKD clinic completed a validated health outcome prioritization tool to ascertain their health outcome priorities. For each patient, the nephrology provider completed the same health outcome prioritization tool. Patients also answered questions to self-rate their health and completed an end-of-life scenarios instrument. We examined the associations between priorities and self-reported health status and between priorities and acceptance of common end-of-life scenarios, and also measured concordance between patients’ priorities and providers’ perceptions of priorities. Results: Among 271 patients (median age 71 years), the top health outcome priority was maintaining independence (49%), followed by staying alive (35%), reducing pain (9%), and reducing other symptoms (6%). Nearly half of patients ranked staying alive as their third or fourth priority. There was no relationship between patients’ self-rated health status and top priority, but acceptance of some end-of-life scenarios differed significantly between groups with different top priorities. Providers’ perceptions about patients’ top health outcome priorities were correct only 35% of the time. Patient-provider concordance for any individual health outcome ranking was similarly poor. Conclusions: Nearly half of older adults with advanced CKD ranked maintaining independence as their top heath outcome priority. Almost as many ranked being alive as their last or second-to-last priority. Nephrology providers demonstrated limited knowledge of their patients’ priorities.

Background and objectives Electronic health record (EHR) patient portals allow individuals to access their medical information with the intent of patient empowerment. However, little is known about portal use in nephrology patients. We addressed this gap by characterizing adoption of an EHR portal, assessing secular trends, and examining the association of portal adoption and BP control (<140/90 mmHg). Design, setting, participants, & measurements Patients seen between January 1, 2010, and December 31, 2012, at any of four university-affiliated nephrology offices who had at least one additional nephrology follow-up visit before June 30, 2013, were included. Sociodemographic characteristics, comorbidities, clinical measurements, and office visits were abstracted from the EHR. Neighborhood median household income was obtained from the American Community Survey 2012. Results Of 2803 patients, 1098 (39%) accessed the portal. Over 87% of users reviewed laboratory results, 85% reviewed their medical information (e.g., medical history), 85% reviewed or altered appointments, 77% reviewed medications, 65% requested medication refills, and 31% requested medical advice from their renal provider. In adjusted models, older age, African-American race (odds ratio [OR], 0.50; 95% confidence interval [95% CI], 0.39 to 0.64), Medicaid status (OR, 0.53; 95% CI, 0.36 to 0.77), and lower neighborhood median household income were associated with not accessing the portal. Portal adoption increased over time (2011 versus 2010: OR, 1.38 [95% CI, 1.09 to 1.75]; 2012 versus 2010: OR, 1.95 [95% CI, 1.44 to 2.64]). Portal adoption was correlated with BP control in patients with a diagnosis of hypertension; however, in the fully adjusted model this was somewhat attenuated and no longer statistically significant (OR, 1.11; 95% CI, 0.99 to 1.24). Conclusion While portal adoption appears to be increasing, greater attention is needed to understand why vulnerable populations do not access it. Future research should examine barriers to the use of e-health technologies in underserved patients with CKD, interventions to address them, and their potential to improve outcomes.
