Background And Objectives: Physical activity has been associated with better health status in diverse populations, but the association in patients on maintenance hemodialysis is less established. Patient-reported physical activities and associations with mortality, health-related quality of life, and depression symptoms in patients on maintenance hemodialysis in 12 countries were examined.
Design, Setting, Participants, & Measurements: In total, 5763 patients enrolled in phase 4 of the Dialysis Outcomes and Practice Patterns Study (2009-2011) were classified into five aerobic physical activity categories (never/rarely active to very active) and by muscle strength/flexibility activity using the Rapid Assessment of Physical Activity questionnaire.
Background: There is limited information about the clinical and prognostic significance of patient-reported recovery time.
Study Design: Prospective cohort study.
Setting & Participants: 6,040 patients in the DOPPS (Dialysis Outcomes and Practice Patterns Study).
Background: Longer travel time to the dialysis unit creates a substantial burden for many patients. This study evaluated the effect of self-reported 1-way travel time to hemodialysis on mortality, health-related quality of life (HR-QOL), adherence, withdrawal from dialysis therapy, hospitalization, and transplantation.
Study Design: Prospective observational cohort.

Background: Identification of haemodialysis patients with problems related to lack of appetite should help prevent adverse outcomes. We studied whether a single question about being bothered by lack of appetite within the prior 4 weeks is related to nutritional status, inflammation and risks of death and hospitalization. Additionally, we assessed associations of lack of appetite with depression, dialysis dose and length of haemodialysis.

Methods: Analysis of baseline data of 9,526 hemodialysis patients from seven countries enrolled in phase I of the Dialysis Outcomes and Practice Patterns Study (DOPPS). Using the Kidney Disease Quality of Life Short Form (KDQOL-SF(TM)), we determined scores for 8 generic scale summaries derived from these scales, i.
Background: The relationship between medication prescription and sexual dysfunction (SD) in dialysis patients is unclear.
Methods: We studied antihypertensive and antidepressive agents prescribed for 7346 patients in the Dialysis Outcomes and Practice Patterns Study phase 1 (DOPPS I) and 8891 patients in DOPPS II. At baseline, DOPPS I patients completed a quality of life survey, including four questions about sexual functioning, from which we created a composite SD scale.
Background: Recent studies suggest a high prevalence of cognitive impairment and dementia in persons with end-stage renal disease (ESRD), yet risk factors for dementia and its prognostic significance in persons with ESRD remain unclear. The goals of this study were to determine the prevalence, correlates and dialysis-related outcomes of dementia in an international sample of haemodialysis patients.
Methods: We analysed data collected from a cohort of 16 694 patients in the Dialysis Outcomes and Practice Patterns Study.
Background: Depressive symptoms and depression are the most frequent psychologic problems reported by hemodialysis patients. We assessed the prevalence of depressive symptoms and physician-diagnosed depression, their variations by country, and associations with treatment by antidepressants among hemodialysis patients. We also assessed whether depressive symptoms were independently associated with mortality, hospitalization, and dialysis withdrawal.

Methods: The Dialysis Outcomes and Practice Patterns Study (DOPPS) has used the Kidney Disease Quality of Life Short Form (KDQOL-SF) to measure ESRD patients' self-assessment of functioning and well-being, as measured by 3 component scores: physical component summary (PCS, 4 subscales), mental component summary (4 subscales), and kidney disease component summary (11 subscales). Several DOPPS studies examined HRQOL's associations with mortality and hospitalization by country, ethnicity (United States only), and in comparison with serum albumin levels; international variations in HRQOL of ESRD patients were also evaluated.
Background: Assessing health-related quality of life (HRQOL) can provide information on the types and degrees of burdens that afflict patients with chronic medical conditions, including end-stage renal disease (ESRD). Several studies have shown important international differences among ESRD patients treated with hemodialysis, but no studies have compared these patients' HRQOL. Our goal was to document international differences in HRQOL among dialysis patients and to identify possible explanations of those differences.
View Article and Find Full Text PDFBackground: We investigated whether indicators of health-related quality of life (HRQOL) may predict the risk of death and hospitalization among hemodialysis patients treated in seven countries, taking into account serum albumin concentration and several other risk factors for death and hospitalization. We also compared HRQOL measures with serum albumin regarding their power to predict outcomes.
Methods: We analyzed data from the Dialysis Outcomes and Practice Patterns Study (DOPPS), an international, prospective, observational study of randomly selected hemodialysis patients in the United States (148 facilities), five European countries (101 facilities), and Japan (65 facilities).

Background: In the United States, an association between mortality risk and ethnicity has been observed among hemodialysis patients. This study was developed to assess whether health-related quality of life (HRQOL) scores also vary among patients of different ethnic backgrounds. Associations between HRQOL and adverse dialysis outcomes (ie, death and hospitalization) also were assessed for all patients and by ethnicity.

We investigated whether survival of grafts relative to fistulae was better in facilities with a preference for grafts, hypothesizing that such facilities may place more grafts because grafts produced superior outcomes.
Methods: The study was based on a national U.
