Improving vascular access knowledge and assessment skill of hemodialysis staff.

Context: Vascular access malfunction and failure contribute to morbidity and hospitalization in hemodialysis populations. Although controversy still exists over the identification and appropriate management of access malfunction, recognition of sentinel signs during physical examination remains an efficient way to screen for access malfunction. Dialysis staff are on the front line of providing quality care to dialysis patients, often being the first ones who could detect early physical signs of access malfunction.

Objectives: The study's purpose is to determine the effect of an advanced vascular access educational module presented to hemodialysis nurses and technicians, focusing on physical examination findings to identify a dialysis access at risk for malfunction.

Methods: Utilizing a quasi-experimental pretest and posttest group design with a nonequivalent comparison control group, the effect of an advanced vascular access education module to improve vascular access knowledge and skill in recognition of sentinel signs of access malfunction was studied in a group of hemodialysis nurses (registered nurses [RNs]) and certified patient care technicians (PCTs).

Results: Knowledge post-test scores (RN, M=94.44, SD=7.05; PCT, M=90.83, SD=7.93) were significantly higher than pretest scores (RN, M=79.54, SD=12.47; PCT M=80.67, SD=7.99) in the intervention group (p<0.001) but not in the comparison group. There were no statistically significant differences in mean skill scores between dialysis nurses (p=0.38) and PCTs (p=0.826) or between intervention and comparison groups (p=0.332).

Conclusions: This study exposes a critical gap in the transition of vascular access knowledge to the practical skill of access assessment. The findings suggest the need for restructuring the clinical training of dialysis nurses and PCTs in vascular access management and care. Newer active learning educational strategies in physical assessment of hemodialysis vascular access should be explored to further support dialysis nurses and PCTs in providing optimal patient care.
