Abbreviations: BSI, bloodstream infection; CI, confidence interval; LTCF, long-term care facility; MDRO-BSI, multidrug-resistant organism bloodstream infection.
aSevere sepsis is defined as sepsis plus sepsis-induced organ dysfunction or tissue hypoperfusion; septic shock is defined as severe sepsis plus hypotension not reversed with fluid resuscitation [23].
