As part of an ongoing prospective survey of nosocomial bacteremias, patients developing bacteremia while undergoing in-centre hemodialysis were observed over a 23 month period. Thirty-six episodes of bacteremia occurred in 30 patients: every episode was directly attributable to hemodialysis. In 28 of the 36 episodes (78%), there was evidence of inflammation with or without drainage of pus at the hemodialysis access site. Staphylococcus aureus accounted for 76% of the bacteremic isolates. Patients hemodialyzing through central venous catheters had a far higher incidence of bacteremia (0.01 per dialysis run) than patients hemodialyzing through vascular grafts (0.0005 per dialysis run).
作为一项正在进行的医院内菌血症前瞻性调查的一部分，对在中心进行血液透析时发生菌血症的患者进行了为期23个月的观察。30例患者发生了36次菌血症发作：每次发作都直接归因于血液透析。在36次发作中的28次（78%），血液透析通路部位有炎症证据，伴有或不伴有脓液引流。金黄色葡萄球菌占菌血症分离株的76%。通过中心静脉导管进行血液透析的患者菌血症发生率（每次透析运行0.01）远高于通过血管移植物进行血液透析的患者（每次透析运行0.0005）。
