^aBloodstream infection rates are shown unadjusted per 100 patient-months (±SD) for all facilities and the facility subgroups analyzed for patients with any vascular access, patients with catheter accesses, and patients without catheters.

^bFor the three large dialysis organizations and the two independently owned facilities, we have randomized their order and omitted the number of monthly observations to preserve confidentiality of the provider organizations. Among these groups of providers, the number of observations ranged from 216 to 1728.
