RESUMO

RATIONALE & OBJECTIVE: Missed hemodialysis (HD) treatments not due to hospitalization have been associated with poor clinical outcomes and related in part to treatment nonadherence. Using data from the Dialysis Outcomes and Practice Patterns Study (DOPPS) phase 5 (2012-2015), we report findings from an international investigation of missed treatments among patients prescribed thrice-weekly HD. STUDY DESIGN: Prospective observational study. SETTING & PARTICIPANTS: 8,501 patients participating in DOPPS, on HD therapy for more than 120 days, from 20 countries. Longitudinal and cross-sectional analyses were performed based on the 4,493 patients from countries in which 4-month missed treatment risk was > 5%. PREDICTORS: The main predictor of patient outcomes was 1 or more missed treatments in the 4 months before DOPPS phase 5 enrollment; predictors of missed treatments included country, patient characteristics, and clinical factors. OUTCOMES: Mortality, hospitalization, laboratory measures, patient-reported outcomes, and 4-month missed treatment risk. ANALYTICAL APPROACH: Outcomes were assessed using Cox proportional hazards, logistic, and linear regression, adjusting for case-mix and country. RESULTS: The 4-month missed treatment risk varied more than 50-fold across all 20 DOPPS countries, ranging from < 1% in Italy and Japan to 24% in the United States. Missed treatments were more likely with younger age, less time on dialysis therapy, shorter HD treatment time, lower Kt/V, longer travel time to HD centers, and more symptoms of depression. Missed treatments were positively associated with all-cause mortality (HR, 1.68; 95% CI, 1.37-2.05), cardiovascular mortality, sudden death/cardiac arrest, hospitalization, serum phosphorus level > 5.5mg/dL, parathyroid hormone level > 300pg/mL, hemoglobin level < 10g/dL, higher kidney disease burden, and worse general and mental health. LIMITATIONS: Possible residual confounding; temporal ambiguity in the cross-sectional analyses. CONCLUSIONS: In the countries with a 4-month missed treatment risk > 5%, HD patients were more likely to die, be hospitalized, and have poorer patient-reported outcomes and laboratory measures when 1 or more missed treatments occurred in a 4-month period. The large variation in missed treatments across 20 nations suggests that their occurrence is potentially modifiable, especially in the United States and other countries in which missed treatment risk is high.

RESUMO

INTRODUCTION: There is little comparable information about hemodialysis (HD) practices in low- and middle income countries, including Russia. Evaluation of HD in Russia and its international comparisons could highlight factors providing opportunities for improvement. METHODS: We examined treatment patterns for 481 prevalent HD patients in 20 Russian facilities, and compared them to contemporary data for 8512 patients from 311 facilities in seven European countries, Japan, and North America. Data were collected according to the uniform methodology of the Dialysis Outcomes and Practice Patterns Study, phase 5. FINDINGS: Compared to other regions, Russian patients were younger (mean age 53.4 years), had a lower percent of males (52.5%), higher arteriovenous fistula use (89.7%), and longer treatment time (mean: 252 minutes, SD: 37 minutes). Mean single pool Kt/V was 1.49 (SD 0.58). Prescription of dialysate calcium 3.5 mEq/L and aluminum-based phosphate binders were high (15.2% and 17.6% of patients, respectively), while intravenous vitamin D and cinacalcet were low (3.3% and 2.2%, respectively). The percents with parathyroid hormone >600 pg/mL (30.9%) and serum phosphate >1.78 mmol/L (37.7%) were high. Use of erythropoetin stimulating agents (78%) was lower, but hemoglobin, ferritin, and transferrin saturation were generally comparable to North America and Europe. DISCUSSION: These detailed data for hemodialysis in Russia demonstrate that many practice patterns contrasted sharply to those in Europe, Japan, and North America, while other features were similar. Our analysis revealed several positive and some less favorable treatment patterns in Russia that represent opportunities for improving patient care and outcomes.

RESUMO

BACKGROUND: This article summarizes the 2012 European Renal Association-European Dialysis and Transplant Association Registry Annual Report (available at www.era-edta-reg.org) with a specific focus on older patients (defined as ≥65 years). METHODS: Data provided by 45 national or regional renal registries in 30 countries in Europe and bordering the Mediterranean Sea were used. Individual patient level data were received from 31 renal registries, whereas 14 renal registries contributed data in an aggregated form. The incidence, prevalence and survival probabilities of patients with end-stage renal disease (ESRD) receiving renal replacement therapy (RRT) and renal transplantation rates for 2012 are presented. RESULTS: In 2012, the overall unadjusted incidence rate of patients with ESRD receiving RRT was 109.6 per million population (pmp) (n = 69 035), ranging from 219.9 pmp in Portugal to 24.2 pmp in Montenegro. The proportion of incident patients ≥75 years varied from 15 to 44% between countries. The overall unadjusted prevalence on 31 December 2012 was 716.7 pmp (n = 451 270), ranging from 1670.2 pmp in Portugal to 146.7 pmp in the Ukraine. The proportion of prevalent patients ≥75 years varied from 11 to 32% between countries. The overall renal transplantation rate in 2012 was 28.3 pmp (n = 15 673), with the highest rate seen in the Spanish region of Catalonia. The proportion of patients ≥65 years receiving a transplant ranged from 0 to 35%. Five-year adjusted survival for all RRT patients was 59.7% (95% confidence interval, CI: 59.3-60.0) which fell to 39.3% (95% CI: 38.7-39.9) in patients 65-74 years and 21.3% (95% CI: 20.8-21.9) in patients ≥75 years.

RESUMO

BACKGROUND: This study provides a summary of the 2010 European Renal Association-European Dialysis and Transplant Association (ERA-EDTA) Registry Annual Report (available at www.era-edta-reg.org). METHODS: This report includes data on renal replacement therapy (RRT) using data from the national and regional renal registries in 29 countries in Europe and bordering the Mediterranean Sea. Individual patient data were received from 27 registries, whereas 18 registries contributed data in aggregated form. We present incidence and prevalence of RRT, transplant rates, survival probabilities and expected remaining lifetimes. The latter two are solely based on individual patient records. RESULTS: In 2010, the overall incidence rate of RRT for end-stage renal disease (ESRD) among all registries reporting to the ERA-EDTA Registry was 123 per million population (pmp) (n = 91 798). The highest incidence rate was reported by Turkey (252pmp) and the lowest reported by Montenegro (21 pmp). The overall prevalence of RRT for ESRD at 31 December 2010 among all registries reporting to the ERA-EDTA Registry was 741 pmp (n = 551 005). The prevalence varied from 124 pmp in Ukraine to 1580 pmp in Portugal. The overall number of renal transplantations performed in 2010 among all registries was 29.2 pmp (n = 21 740). The highest overall transplant rate was reported from Spain, Cantabria (73 pmp), whereas the highest transplant rate for living donor kidneys was reported from the Netherlands (28 pmp). For patients who started RRT between 2001 and 2005, the unadjusted 5-year patient survival on RRT was 46.2% [95% confidence interval (CI) 46.0-46.3], and on dialysis 38.6% (95% CI 38.5-38.8). The unadjusted 5-year patient survival after the first renal transplantation performed between 2001 and 2005 was 86.6% (95% CI 86.1-87.1) for deceased donor kidneys and 94.1% (95% CI 93.4-94.8) for living donor kidneys.
