Background

Hemodialysis is an important method to maintain the life of patients with end-stage renal disease. The number of hemodialysis patients in southwest China is increasing year by year, but there are few studies on the current situation of vascular access for hemodialysis patients in this region.

Methods

A cross-sectional survey study was conducted using a questionnaire. Statistical analysis was performed to determine the influence of the first choice of dialysis access modality, level of open surgery and interventional surgery in the hospital.

Results

A total of 228 hospitals in southwest China with 30,068 hemodialysis patients were included in this study. The number of patients with long-term hemodialysis access as autogenous arteriovenous fistula (AVF) was the highest, accounting for 81.35%. The number of patients whose first hemodialysis access was AVF was lower (32.29%) and the number of patients whose first hemodialysis access was temporary catheter was the highest (57.42%). 61.40% of physicians preferred femoral vein placement for initial hemodialysis patients. Grade A tertiary hospital (the highest level of hospital in China) had a significant effect (95% CI 0.021-0.744) on physicians' choice of whether to place a central venous temporary catheter or a long-term catheter for the first time. Local economic situation (estimated by house price per square meter) was an independent influence on the ability of hospitals to perform open procedures for hemodialysis access (95% CI 1.407-44.657, 95% CI 2.791-77.801).

Conclusion

Currently, more than half of hemodialysis patients in southwest China still have their first hemodialysis access as femoral vein placement, but 81.35% of patients end up with AVF as long-term hemodialysis access. Hospital grade had a significant impact on the physician's choice of the type of central venous catheter to be placed for the first time. The economic level of the city where the hospital was located also had a significant effect on the level of hospital prescribing and interventional procedures.
