RESUMEN
BACKGROUND: Clostridioides difficile is the most prevalent hospital-onset (HO) infection. There are significant financial and safety impacts associated with HO-C. difficile infections (HO-CDIs) for both patients and health care organizations. The incidence of HO-CDIs at our community hospital within an academic acute health care system was continuously above the national benchmark. METHODS: In response to the high HO-CDI rates at our facility, an interprofessional team selected evidence-based interventions with the goal of reducing HO-CDI incidence rates. Interventions included: diagnostic stewardship, enhanced environmental cleaning, antimicrobial stewardship and education and accountability. RESULTS: After one year, we achieved a 63% reduction in HO-CDI and have sustained a 77% reduction. The infection rate remained below national benchmark for HO-CDI for over 4 years at a rate of 2.80 per 10,000 patient days and a SIR of 0.43 in 2020. DISCUSSION: Multiple evidence-based interventions were successfully implemented over several service lines over a 4-year period through the collaboration of an interprofessional team. The addition of an accountability processes further improved compliance with standards of practice. CONCLUSIONS: Collaboration of an interprofessional team led to substantial and sustained reductions in HO-CDI.

Objective: To determine the impact of an inpatient stewardship intervention targeting fluoroquinolone use on inpatient and postdischarge Clostridioides difficile infection (CDI). Design: We used an interrupted time series study design to evaluate the rate of hospital-onset CDI (HO-CDI), postdischarge CDI (PD-CDI) within 12 weeks, and inpatient fluoroquinolone use from 2 years prior to 1 year after a stewardship intervention. Setting: An academic healthcare system with 4 hospitals. Patients: All inpatients hospitalized between January 2017 and September 2020, excluding those discharged from locations caring for oncology, bone marrow transplant, or solid-organ transplant patients. Intervention: Introduction of electronic order sets designed to reduce inpatient fluoroquinolone prescribing. Results: Among 163,117 admissions, there were 683 cases of HO-CDI and 1,104 cases of PD-CDI. In the context of a 2% month-to-month decline starting in the preintervention period (P < .01), we observed a reduction in fluoroquinolone days of therapy per 1,000 patient days of 21% after the intervention (level change, P < .05). HO-CDI rates were stable throughout the study period. In contrast, we also detected a change in the trend of PD-CDI rates from a stable monthly rate in the preintervention period to a monthly decrease of 2.5% in the postintervention period (P < .01). Conclusions: Our systemwide intervention reduced inpatient fluoroquinolone use immediately, but not HO-CDI. However, a downward trend in PD-CDI occurred. Relying on outcome measures limited to the inpatient setting may not reflect the full impact of inpatient stewardship efforts.
