The effects of vascular access types on the survival and quality of life and depression in the incident hemodialysis patients.

ABSTRACT: Background: Although arteriovenous fistula (AVF) is the preferred vascular access for hemodialysis (HD), the association between vascular access types and quality of life is not well-known. We investigated the relationships between HD vascular access types and all-cause mortality, health-related quality of life (HRQOL) and the degree of depression in a large prospective cohort.Methods: A total of 1461 patients who newly initiated HD were included. The initial vascular access types were classified into AVF, arteriovenous graft (AVG), and central venous catheter (CVC). The primary outcomes were all-cause mortality and HRQOL and depression. The secondary outcome was all-cause hospitalization. Kidney Disease Quality of Life Short Form 36 (KDQOL-36) and Beck's depression inventory (BDI) scores were measured to assess HRQOL and depression.Results: Among 1461 patients, we identified 314 patients who started HD via AVF, 76 via AVG, and 1071 via CVC. In the survival analysis, patients with AVF showed significantly better survival compared with patients with other accesses (p < .001). The AVF and AVG group had higher KDQOL-36 score and lower BDI score than CVC group at 3 months and 12 months after the initiation of HD. The frequency of hospitalization was higher in patients with AVG compared to those with AVF (AVF 0.7 vs. AVG 1.1 times per year) (p = .024).Conclusions: The patients with AVF had better survival rate and low hospitalization rate, and the patients with AVF or AVG showed both higher HRQOL and lower depression scores than those with CVC.

Project description:Vascular access (VA) is the cornerstone for carrying out hemodialysis, yet it may bring in complications and leads to hemodialysis quality decline. This study aimed to explore the impact of vascular access types, including arteriovenous shunts and central venous catheter on all-cause mortality after adjustment of other risk factors. Total 738 ESRD patients aged over 40 year old receiving regular hemodialysis therapies were recruited between January 2001 and December 2010 from a single hemodialysis center in northern Taiwan. We ascertained the causes and date of death by linking our hospital database with Nationwide Mortality Registry Database. VA types and biochemistry parameters were extracted from the electronic hospital records. Patients were categorized into three groups, including (1)arteriovenous shunts (AVF)/arteriovenous shunts with Gortex®(AVG); (2)AVF/AVG combined central venous catheter; (3)catheter only. The time-dependent influence of vascular types i.e. initiation and follow-up period was also assessed. The mean follow-up time was 4.5 years. In patients using central venous catheter for initiation of hemodialysis, the adjusted hazard ratio (HR) for all-cause mortality was 1.55(95%CI: 1.09, 2.21), when compared with AVF/AVG. In the follow-up period, after adjustment for other risk factors, the multivariable analysis showed that the adjusted HRs were 3.23(95%CI: 1.85, 5.64) and 1.45(95%CI: 1.11, 1.91) for catheter only and AVF/AVG plus catheter, respectively. Our results showed that vascular accesses used for hemodialysis had different and time-dependent impact on patients' long-term survival. Patients who started hemodialysis with central venous catheter had significantly higher all-cause mortality rate. Furthermore, in the follow-up period, patients both in the catheter only and AVF/AVG plus catheter groups also had the significant all-cause mortality rates. Our results support the early establishment of arteriovenous shunt for the chronic kidney disease patients.

Project description:Rationale & objectiveAs the proportion of arteriovenous fistulas (AVFs) compared with arteriovenous grafts (AVGs) in the United States has increased, there has been a concurrent increase in interventions. We explored AVF and AVG maturation and maintenance procedural burden in the first year of hemodialysis.Study designObservational cohort study.Setting & participantsPatients initiating hemodialysis from July 1, 2012, to December 31, 2014, and having a first-time AVF or AVG placement between dialysis initiation and 1 year (N = 73,027), identified using the US Renal Data System (USRDS).PredictorsPatient characteristics.OutcomeSuccessful AVF/AVG use and intervention procedure burden.Analytical approachFor each group, we analyzed interventional procedure rates during maturation maintenance phases using Poisson regression. We used proportional rate modeling for covariate-adjusted analysis of interventional procedure rates during the maintenance phase.ResultsDuring the maturation phase, 13,989 of 57,275 patients (24.4%) in the AVF group required intervention, with therapeutic interventional requirements of 0.36 per person. In the AVG group 2,904 of 15,572 patients (18.4%) required intervention during maturation, with therapeutic interventional requirements of 0.28 per person. During the maintenance phase, in the AVF group 12,732 of 32,115 patients (39.6%) required intervention, with a therapeutic intervention rate of 0.93 per person-year. During maintenance phase, in the AVG group 5,928 of 10,271 patients (57.7%) required intervention, with a therapeutic intervention rate of 1.87 per person-year. For both phases, the intervention rates for AVF tended to be higher on the East Coast while those for AVG were more uniform geographically.LimitationsThis study relies on administrative data, with monthly recording of access use.ConclusionsDuring maturation, interventions for both AVFs and AVGs were relatively common. Once successfully matured, AVFs had lower maintenance interventional requirements. During the maturation and maintenance phases, there were geographic variations in AVF intervention rates that warrant additional study.

Project description:BackgroundCommencing hemodialysis (HD) with an arteriovenous access is associated with superior patient outcomes compared with a catheter, but the majority of patients in Australia and New Zealand initiate HD with a central venous catheter. This study examined patient and center factors associated with arteriovenous fistula/graft access use at HD commencement.MethodsWe included all adult patients starting chronic HD in Australia and New Zealand between 2004 and 2015. Access type at HD initiation was analyzed using logistic regression. Patient-level factors included sex, age, race, body mass index (BMI), smoking status, primary kidney disease, late nephrologist referral, comorbidities, and prior RRT. Center-level factors included size; transplant capability; home HD proportion; incident peritoneal dialysis (average number of patients commencing RRT with peritoneal dialysis per year); mean weekly HD hours; average blood flow; and achievement of phosphate, hemoglobin, and weekly Kt/V targets. The study included 27,123 patients from 61 centers.ResultsArteriovenous access use at HD commencement varied four-fold from 15% to 62% (median 39%) across centers. Incident arteriovenous access use was more likely in patients aged 51-72 years, males, and patients with a BMI of >25 kg/m2 and polycystic kidney disease; but use was less likely in patients with a BMI of <18.5 kg/m2, late nephrologist referral, diabetes mellitus, cardiovascular disease, chronic lung disease, and prior RRT. Starting HD with an arteriovenous access was less likely in centers with the highest proportion of home HD, and no center factor was associated with higher arteriovenous access use. Adjustment for center-level characteristics resulted in a 25% reduction in observed intercenter variability of arteriovenous access use at HD initiation compared with the model adjusted for only patient-level characteristics.ConclusionsThis study identified several patient and center factors associated with incident HD access use, yet these factors did not fully explain the substantial variability in arteriovenous access use across centers.

Project description:BACKGROUND:In this single-center, retrospective observational study, we assessed the long-term patency of vascular access (VA) after first VA placement to uncover independent risk factors associated with VA patency in Asian hemodialysis (HD) patients stratified by age. We also investigated factors associated with VA patency among older HD patients according to the type of VA in the overall study population. METHODS:The study period was from January 2011 to December 2013. A total of 651 chronic HD patients with confirmed first upper-extremity VA placement were enrolled, and their records were analyzed retrospectively. A total of 445 patients (68.4%) made up the nonelderly group (< 65 years), and 206 patients (31.6%) were in the elderly group (≥ 65 years). Study outcomes were defined as primary or secondary VA patency. RESULTS:Autologous arteriovenous fistula (AVF) was more common in the nonelderly group (P < 0.01). Kaplan-Meier curve survival analysis indicated that primary patency was longer in the nonelderly group (P < 0.01); secondary patency, however, was similar between groups (P = 0.37). The multivariate analysis of factors associated with primary VA patency revealed that increased age (hazard ratio [HR], 1.02; 95% confidence interval [CI], 1.01-1.03; P < 0.01) was associated with shorter primary patency, and AVF (HR, 0.38; 95% CI, 0.28-0.51; P < 0.01) was associated with longer primary patency. AVF (HR, 0.57; 95% CI, 0.37-0.87; P = 0.010) and diabetes mellitus (HR, 1.56; 95% CI, 1.07-2.29; P = 0.02) were independently associated with longer and shorter secondary patency periods, respectively; however, increased age was not a risk factor for decreased secondary patency. CONCLUSIONS:Increased age was associated with shorter primary patency but not secondary patency, whereas AVF placement was associated with longer primary and secondary patency. Considering the similar rates of secondary patency between groups and the superior patency of AVF compared to arteriovenous graft, a fistula-first strategy should be applied to appropriate older patients.
