- Abstract
Background Chlorhexidine (CHG) bathing decreases the incidence of bloodstream infections in intensive care units, but its effect has been understudied in patients with hematological malignancies in noncritical care units. Methods Adults with hematological malignancies hospitalized for cytotoxic chemotherapy in noncritical care units were offered daily 2% CHG bathing. We compared outcomes of patients who chose CHG bathing (CHG group) with outcomes of those who did not choose CHG bathing (usual-care group). The primary outcome was gram-positive cocci–related, skin flora–related, or central line–associated bloodstream infection. The negative control outcome was gut-origin bacteremia. Results The CHG group (n = 485) had a crude incidence rate of the primary outcome that was 60% lower than the rate for the usual-care group (n = 408; 3.4 vs 8.4 per 1000 patient-days, P =.02) but had a similar crude incidence rate of the negative control outcome (4.5 vs 3.2 per 1000 patient-days; P =.10). In multivariable analyses, CHG bathing was associated with a 60% decrease in the primary outcome (adjusted hazard ratio [HR], 0.4; P <.001). In contrast, CHG bathing had no effect on the negative control outcome (adjusted HR, 1.1; P =.781). CHG bathing was well tolerated by participants in the CHG group. Conclusions CHG bathing could be a highly effective approach for preventing gram-positive cocci–related, skin flora–related, or central line–associated bacteremia in patients with hematological malignancies who are hospitalized for cytotoxic chemotherapy in noncritical care units.
