Abstract

This study evaluates and improves the patient education and care process before and after arteriovenous fistula surgery in hemodialysis patients. Inadequate implementation of this process may lead to multiple clinical risks. Currently, Southern X Hospital lacks a standardized patient education protocol, resulting in duplicated, omitted, or inconsistent content. These deficiencies negatively affect patients' comprehension and adherence, potentially leading to resource waste and reduced dialysis quality. To address these issues, this study applies Failure Mode and Effects Analysis (FMEA) to systematically identify potential failure modes within the education and care continuum. The CRITIC (Criteria Importance Through Intercriteria Correlation) method is used to generate objective weights for severity, occurrence, detectability, and expected cost, while Grey Relational Analysis (GRA) ranks overall risks based on weighted scores to overcome the subjectivity and ranking limitations of traditional FMEA scoring. Based on literature review, process mapping, and expert surveys, the study identifies 24 failure modes across six stages: preoperative preparation, postoperative care, vascular access maturation, vascular access training, daily maintenance, and management of access complications. The five highest-ranked risks include failure to rotate puncture sites, inadequate monitoring of pseudoaneurysm development, failure to perform vascular access reconstruction as prescribed, improper hemostasis technique after needle removal, and inadequate wound care. Accordingly, five improvement strategies were developed to reduce risks associated with these critical failures. This study provides a scientific, structured risk-evaluation framework for patient education processes, supporting dialysis units in establishing standardized procedures, revising care guidelines, and implementing quality improvement initiatives to enhance patient self-management and dialysis-related quality of life.

Description

This study used FMEA with CRITIC and GRA to evaluate risks in the vascular access education process for hemodialysis patients. Twenty-four failure modes were identified, with the highest risks related to puncture-site rotation, pseudoaneurysm monitoring, hemostasis, wound care, and access reconstruction. Five improvement strategies were developed to standardize education and strengthen patient self-management.

FMEA-Based Risk Assessment and Improvements for Vascular Access Education in Hemodialysis

Toronto, Ontario, Canada

This study evaluates and improves the patient education and care process before and after arteriovenous fistula surgery in hemodialysis patients. Inadequate implementation of this process may lead to multiple clinical risks. Currently, Southern X Hospital lacks a standardized patient education protocol, resulting in duplicated, omitted, or inconsistent content.

To address these issues, this study applies Failure Mode and Effects Analysis (FMEA) to systematically identify potential failure modes within the education and care continuum. The CRITIC (Criteria Importance Through Intercriteria Correlation) method is used to generate objective weights for severity, occurrence, detectability, and expected cost, while Grey Relational Analysis (GRA) ranks overall risks based on weighted scores to overcome the subjectivity and ranking limitations of traditional FMEA scoring.
