Abstract

Purpose
We evaluated the incidence and characteristics of Clostridioides difficile infection (CDI) in Korean children.
Methods
Medical records of patients aged 2–18 years and diagnosed with CDI at a tertiary hospital between 2009 and 2018 were analyzed. The patients were classified into three CDI groups: community-acquired (CA), community onset-health care facility-associated (COHCFA), and healthcare facility onset (HO).
Results
The incidence of CDI increased from 1.00 to 10.01 cases per 10,000 admissions from 2009 to 2018 (P<0.001). As compared to the CA group, the HO group had a higher frequency of operation and malignancy as predisposing factors (40.4% vs. 0.0%, P=0.001; and 27.7% vs. 0.0%, P=0.027, respectively), frequency and number of previous antibiotic use (97.9% vs. 31.3%, P<0.001; and 2 vs. 0, P<0.001, respectively), and median postdiagnosis hospital stay (13 vs. 5 days, P=0.008). The CO-HCFA group had a lower median age and higher frequency of malignancy than the CA group (5 vs. 13 years, P=0.012; and 30.8% vs.0.0%, P=0.030, respectively). As compared to the HO group, the CA group had a higher frequency of abdominal pain and hematochezia (56.3% vs. 10.6%, P=0.001; and 50.0% vs. 10.6%, P=0.002, respectively), inflammatory bowel disease (68.8% vs. 2.1%, P=0.001), and intravenous metronidazole treatment (37.5% vs. 2.1%,P=0.001).
Conclusions
With the increasing incidence of pediatric CDI, awareness regarding its epidemiology and clinical characteristics is important to manage nosocomial infections.
