[Effects of distance between residence and hemodialysis unit on cardiovascular complications and treatments of maintenance hemodialysis patients].

Objective: To explore the effects of etiological classification and the distance between residence and hemodialysis unit on cardiovascular complications and treatments in maintenance hemodialysis (MHD) patients.

Methods: A total of 756 MHD patients were collected from 12 hemodialysis centers of Guiyang, China between January 2011 and May 2012. Their distribution characteristics and correlations were based on medical records. And statistical analyses were performed.

Results: The ratio of males and females was 1.45: 1. And their mean age was (49.1 ± 14.7) years old. And 496 (65.6%) cases suffered from cardiovascular complications. The analysis of multi-factor Logistic regression revealed that distance between residence and dialysis unit was an independent risk factor of cardiovascular complications. The group of the farthest distance ( > 30 km) had the worst influence on dialysis adequacy Kt/V score, urea clearance rate, dialysis frequency and time per week. And the levels of blood phosphorus, triglyceride and cholesterol in the fourth group had marked elevations. It had a significant positive correlation with distance (P < 0.05).

Conclusion: The distance between residence and dialysis unit is an independent risk factor of cardiovascular complications in MHD patients. The farthest distance ( > 30 km) has the greatest influence on dialysis adequacy.
