Cross-sectional.
SETTING: Fourteen hospitals in Henan Province.
PARTICIPANTS: The overall incidence rate was 7.74/1000
catheter-days, affecting 38.61% of all patients, for
catheter infections, 10.58/1000
catheter-days, affecting 56.65% of all patients, for
catheter dysfunction, and 0.68/1000
catheter-days, affecting 8.79% of all patients, for central vein
stenosis. Multivariate analysis showed that increased age, diabetes, primary educational level or below, rural residence, lack of a nephropathy visit before dialysis and pre-established permanent vascular access, not taking oral drugs to prevent
catheter thrombus, lower
serum albumin levels and higher
ferritin levels were independently associated with
catheter infections. Rural residence, not taking oral drugs to prevent
thrombus, lack of an imaging examination after
catheter insertion, non-tunnel
catheter type, lack of medical insurance, lack of nephropathy visit before dialysis and pre-established permanent vascular access, left-sided
catheter position, access via the femoral vein and lower haemoglobin level were independently associated with
catheter dysfunction. Diabetes, lack of nephropathy visit before dialysis and pre-established permanent vascular access, lack of oral drugs to prevent
catheter thrombus, left-sided
catheter location and higher number of
catheter insertions, were independently associated with central vein
stenosis.
CONCLUSIONS:
