Multi-Disciplinary Vascular Access Care and Access Outcomes in People Starting Hemodialysis Therapy.

ABSTRACT:

Background and objectives

Fistulas, the preferred form of hemodialysis access, are difficult to establish and maintain. We examined the effect of a multidisciplinary vascular access team, including nurses, surgeons, and radiologists, on the probability of using a fistula catheter-free, and rates of access-related procedures in incident patients receiving hemodialysis.

Design, setting, participants, & measurements

We examined vascular access outcomes in the first year of hemodialysis treatment before (2004-2005, preteam period) and after the implementation of an access team (2006-2008, early-team period; 2009-2011, late-team period) in the Calgary Health Region, Canada. We used logistic regression to study the probability of fistula creation and the probability of catheter-free fistula use, and negative binomial regression to study access-related procedure rates.

Results

We included 609 adults (mean age, 65 [±15] years; 61% men; 54% with diabetes). By the end of the first year of hemodialysis, 102 participants received a fistula in the preteam period (70%), 196 (78%) in the early-team period (odds ratios versus preteam, 1.47; 95% confidence interval, 0.92 to 2.35), and 139 (66%) in the late-team period (0.85; 0.54 to 1.35). Access team implementation did not affect the probability of catheter-free use of the fistula (odds ratio, 0.87; 95% confidence interval, 0.52 to 1.43, for the early; and 0.89; 0.52 to 1.53, for the late team versus preteam period). Participants underwent an average of 4-5 total access-related procedures during the first year of hemodialysis, with higher rates in women and in people with comorbidities. Catheter-related procedure rates were similar before and after team implementation; relative to the preteam period, fistula-related procedure rates were 40% (20%-60%) and 30% (10%-50%) higher in the early-team and late-team periods, respectively.

Conclusion

Introduction of a multidisciplinary access team did not increase the probability of catheter-free fistula use, but resulted in higher rates of fistula-related procedures.

Project description:Background and objectivesMedicare reimbursement policy encourages frequent provider visits to patients with ESRD undergoing hemodialysis. This study sought to determine whether more frequent face-to-face provider (physician and advanced practitioner) visits lead to more procedures and therapeutic interventions aimed at preserving arteriovenous fistulas and grafts, improved vascular access outcomes, and fewer related hospitalizations.Design, setting, participants, & measurementsMultivariable regression was used to evaluate the association between provider (physician and advanced practitioner) visit frequency and interventions aimed at preserving vascular access, vascular access survival, hospitalization for vascular access infection, and outpatient antibiotic use in a cohort of 63,488 Medicare beneficiaries receiving hemodialysis in the United States. Medicare claims were used to identify the type of vascular access used, access-related events, and vascular access failure.ResultsOne additional provider (physician and advanced practitioner) visit per month was associated with a 13% higher odds of receiving an intervention to preserve vascular access (95% confidence interval [95% CI], 12% to 14%) but was not associated with vascular access survival (hazard ratio, 1.01; 95% CI, 0.99 to 1.03). One additional provider visit was associated with a 9% (95% CI, 5% to 14%) lower odds of hospitalization for vascular access infection and a corresponding 9% (95% CI, 5% to 14%) higher odds of outpatient intravenous antibiotic administration. However, the associated changes in absolute probabilities of hospitalization and antibiotic administration were small.ConclusionsMore frequent face-to-face provider (physician and advanced practitioner) visits were associated with more procedures and therapeutic interventions aimed at preserving vascular accesses, but not with prolonged vascular access survival and only a small decrease in hospitalization for vascular access.

Project description:BackgroundTo describe vascular access (VA)-related decision-making from the patient perspective, in patients who have already chosen hemodialysis as their renal replacement modality, and identify areas where physicians can improve this experience.MethodsIn-person, semi-structured interviews with 15 patients with end-stage kidney disease were systematically analyzed by two independent researchers using thematic analysis. Interviews were conducted until systematic analysis revealed no new themes.ResultsPatients had mean age 57 (range 22-85), with seven males and diverse racial/ethnic/marital status. All (15/15) patients viewed VA as "intertwined and interrelated" with dialysis, prioritized the dialysis, described the VA merely as the "hookup" to life-preserving dialysis and gave it minimal consideration. Three themes were identified: consolidation of dialysis and VA, reliance on supportive advisors and communication with physicians. Although 14/15 patients described processes common to medical decision-making, including information seeking, learning from the experiences of others, and weighing risks and benefits, they did not apply these processes specifically to VA. While all participants took ownership of the VA decision, they lacked clear understanding about the different types of VA and their consequences. Most patients (14/15) depended on family and friends for reinforcement, motivation and advice. Patients all described physician characteristics they associated with trustworthiness, the most common being listening and explaining, demonstrating empathy and making an effort to meet the patient's individual needs. Perceived arrogance, unavailability and lack of expertise represented untrustworthiness. The majority (14/15) accepted VA recommendations from physicians they found trustworthy and authoritative.ConclusionsThe study participants were minimally engaged in VA decision-making. Educational aids and shared decision-making tools are needed to empower patients to make better-informed, self-efficacious VA decisions.
