Special ReportReport of the Standardized Outcomes in Nephrology–Hemodialysis (SONG-HD) Consensus Workshop on Establishing a Core Outcome Measure for Hemodialysis Vascular Access
Section snippets
Background
A functioning vascular access is a lifeline for patients requiring hemodialysis (HD), but has a high risk of complications.1 Vascular access complications account for approximately 20% to 30% of hospital admissions for patients on HD and incur substantial health care costs.2, 3 One in every 2 arteriovenous fistulas or grafts will fail to function within the first year of creation and necessitate further interventions for problems such as inadequate maturation, stenosis, or thrombosis.4, 5, 6, 7
Context and Scope
The international SONG-HD vascular access consensus workshop was convened in Chicago during the American Society of Nephrology Kidney Week Conference in 2016 for stakeholders to discuss the identification and implementation of a core outcome measure for vascular access to be reported in all trials in HD. The top prioritized outcomes were vascular access function and infection based on a systematic review and interim results from an international survey on vascular access outcomes that was
Summary of Workshop Discussion
Overall, we identified 5 themes from the discussion: (1) capturing the broad applicability of function, (2) emphasizing experiential relevance and severity, (3) demonstrating feasibility of implementation, (4) ensuring robustness and validity, and (5) integrating patients’ values and preferences. Illustrative quotations for each theme are shown in Box 1 and contributions from breakout groups to the respective themes are listed in Table S2. Possible outcome measures discussed during the workshop
Discussion
Access function is highly relevant, important, and appropriate as the core outcome for vascular access because of its applicability to all access types, impact on quality of life and survival of patients, and representation of a multidisciplinary team effort. It encapsulates other important aspects of a vascular access, such as the ability to cannulate and receive adequate dialysis, and has implications on potential complications, such as pain, hospitalization for access procedures, or access
