Introduction
The mortality rate of hemodialysis patients is extremely high and it is significantly affected by vascular access dysfunction. Our research aimed to determine predictive parameters of arteriovenous fistula functioning and survival in a one-year follow-up period.
Methods
The research was organized as a prospective, one-year study, which included 120 dialysis patients who were followed for one year. We recorded the demographic and gender structure, clinical parameters, and laboratory findings significant for the survival and functioning of arteriovenous fistulas. Laboratory findings are presented as the mean values of the analysis at the beginning and the end of the one-year control period.
Results
Univariable regression analysis confirmed the predictive significance of anastomosis positioning, type of vascular access, length of hemodialysis treatment, hemoglobin, Kt/V index values, and creatinine concentration for one-year survival, but multivariable regression analysis confirmed predictive significance only for length of treatment. Univariable regression analysis revealed significant predictors of vascular access function for the length of hemodialysis treatment, diastolic blood pressure, leukocytes, platelets, hemoglobin, creation of an arteriovenous fistula by a nephrologist, starting hemodialysis with a fistula and not with a central venous catheter, multivariable regression analysis confirmed predictive significance for the length of dialysis treatment and creation of an arteriovenous fistula by a nephrologist.
Conclusion
A prognostically important parameter for the one-year survival of a patient on hemodialysis is the length of dialysis treatment. In contrast, predictive parameters for the functioning of an arteriovenous fistula are the length of dialysis and the creation of a fistula by a nephrologist.
