How many CDIs were reported in 2011?

After tremendous increases during 2000 and 2011, CDI rates plateaued at historic highs and have since begun to show some decline. In 2011, an estimated 476,400 CDIs in the United States were reported; C. diff accounted for 12.1% of all healthcare-associated infections. Between 2011-2017, nucleic acid amplification tests (NAAT) increased in use. After adjusting for the use of NAAT, the estimated CDI burden decreased by 24% during 2011-2017 with 365,200 cases reported in 2017. The decrease was driven by a 36% decrease in cases of healthcare-associated CDI, while community-associated CDI was unchanged. After adjusting for NAAT use, hospitalized cases of CDI decreased by 24%. There were no changes in estimates of first recurrences and in-hospital deaths during 2011-2017. We have also seen a decline in ribotype 027, an epidemic strain of C. diff that emerged in the 2000s. This decline in ribotype 027 might be partly driven by a decreased use of fluoroquinolone in U.S. hospitals. Continued efforts to improve adherence to recommended infection prevention measures and implement diagnostic and antibiotic stewardship in both inpatient and outpatient settings will further reduce CDI.
