Indicators for evaluating the vascular access of users in hemodialysis

Abstract

The purpose of this study was to develop reliable assessment instruments to measure hemodialysis vascular access. The design of healthcare indicators involved an indepth-analysis of vascular access practices in hemodialysis and their underlying theoretical rationale, and was grounded on Donabedian's framework. Four indicators were selected: performance of temporary double-lumen catheter, maintenance of temporary double-lumen catheter, monitoring of arteriovenous fistula and complications of arteriovenous fistulas. The first three are process-oriented while the last one relate to outcomes. Data was collected in October and November 2008 using a tree-part questionnaire, thus divided: assessment of the indicators' operations manual, assessment of health attributes of the indicators and assessment of each of the components. The validation of the indicators was carried out by a panel of nine internationally renowned experts in nephrology. All indicators were validated by the panel, with at least a 75% favorable consensus. It is believed that the use of this instrument contributes for evaluation and improvement of quality in hemodialysis services.
