Antimicrobial stewardship without infectious disease physician for patients with candidemia: A before and after study

BACKGROUND: Little is known about the effects of antimicrobial stewardship team (AST) without infectious disease physician (IDP) on clinical outcome in patients with candidemia. METHODS: We conducted a before and after study involving patients with hospital‐acquired candidemia at a tertiary hospital without IDPs. The AST consisted of physicians, pharmacists, nurse, microbiologist, and administrative staff. A candidemia care bundle was developed based on the Infectious Disease Society of America (IDSA) guideline. The non‐IDP AST provided recommendations to the attending physicians whose patients developed candidemia during hospitalization. The primary outcome was 30‐day all‐cause mortality, while the secondary outcomes were adherence to the IDSA guidelines regarding the management of candidemia. Data of up to 3 years of preintervention and 3 years of intervention period were analyzed. RESULTS: By 30 days, 11 of 46 patients (23.9%) in the intervention group and 7 of 30 patients (23.3%) in the preintervention group died (adjusted hazard ratio for the intervention group: 0.68 [95% CI 0.24‐1.91]). The non‐IDP AST was associated with appropriate empirical antifungal therapy (100% vs 60.0%; proportion ratio 1.67 [95% CI 1.24‐2.23]), appropriate duration of treatment (84.7% vs 43.3%; 1.96 [1.28‐3.00]), removal of central venous catheters (94.4% vs 70.8%; 1.33 [1.02‐1.74]), and ophthalmological examination (93.5% vs 63.3%; 1.48 [1.12‐1.96]). CONCLUSIONS: Although we found no significant difference in 30‐day mortality, the non‐IDP AST was associated with improved adherence to guidelines for management of candidemia.
