Abstract In the hemodialysis population, the incidence of S taphylococcus aureus colonization has been documented to be as high as 80%; effective prophylaxis of vascular access infection and bacteremia is a worthwhile goal in the management of hemodialysis population. Surveillance of 50 hemodialysis patients for S . aureus ‐positive nasal cultures was performed by monthly nasal swabs over a 12‐month period. All patients were performing dialysis using hemodialysis catheters thrice weekly. All positive cultures were treated with a prophylactic antibiotic regimen. Thirty‐one patients (62%) had one or more positive cultures. The surveillance period was longer in the S . aureus nasal carriers ( p < 0.01). The frequency of positive cultures correlated with the duration of surveillance ( p < 0.05). The incidence of S . aureus bacteremia was greater in patients with three or more positive cultures ( p < 0.05). This study suggests that continuous surveillance for S . aureus nasal colonization is essential to properly identify all hemodialysis patients using catheters at risk of developing S . aureus bacteremias.
