Abstract

Background

Unnecessary antibiotic use (AU) contributes to increased rates of Clostridioides difficile Infection (CDI). The impact of antibiotic restriction on hospital-onset CDI (HO-CDI) has not been assessed in a large group of U.S. acute care hospitals (ACHs).

Methods

We examined cross-sectional and temporal associations between rates of hospital-level AU and HO-CDI using data from 549 ACHs. HO-CDI, a discharge with a secondary ICD-9-CM for CDI (008.45) and treatment with metronidazole or oral vancomycin ≥ 3 days after admission. Analyses were performed using multivariable generalized estimating equation models adjusting for patient and hospital characteristics.

Results

During 2006-2012, the unadjusted annual rates of HO-CDI and total AU were 7.3 per 10,000 patient-days (PD) (95% CI: 7.1-7.5) and 811 days of therapy (DOT)/1,000 PD (95% CI: 803-820), respectively. In the cross-sectional analysis, for every 50 DOT/1,000 PD increase in total AU, there was a 4.4% increase in HO-CDI.

For every 10 DOT/1,000 PD increase in use of third- and fourth-generation cephalosporins or carbapenems there was a 2.1% and 2.9% increase in HO-CDI, respectively. In the time-series analysis, the 6 ACHs with a ≥ 30% decrease in total AU had a 33% decrease in HO-CDI (rate ratio, 0.67; 95% CI, 0.47-0.96); ACHs with a ≥ 20% decrease in fluoroquinolone or third- and fourth-generation cephalosporin use had a corresponding decrease in HO-CDI of 8% and 13%, respectively.

Conclusions

At an ecologic level, reductions in total AU, use of fluoroquinolones and third- and fourth-generation cephalosporins were each associated with decreased HO-CDI rates.
