Background: Significant increase in rates of Clostridioides difficile associated diarrhea (CDI) has been reported globally but there remains a paucity of data from Saudi Arabia.

Methodology: Prospective hospital-based surveillance for CDI using the Center for Disease Control (CDC) criteria was conducted from June to November 2015 in a tertiary healthcare facility in Riyadh, Saudi Arabia.

Results: During the surveillance period, 106 episodes of CDI were identified among 59 patients in 137,230 patient-days. The incidence of CDI was 3.5 per 10,000 patient days. Of the 106 episodes, 58% (n=61) were new cases, 12% (n=13) were recurrent cases and 30% (n=32) were duplicate cases. Majority of the new cases (n/N=43/61; 70%) were healthcare onset, followed by community onset (21%) and 8% were community-onset healthcare associated. No statistically significant change in trend was observed during the surveillance period. The most prevalent CDI risk factor was use of proton pump inhibitor (PPI) (92%) followed by prolonged use of antibiotics (77%). Pareto-analysis indicated that controlling for PPI use, prolong and multiple antibiotic exposure and prolonged hospitalization results in 80% CDI reduction.

Conclusion: The findings indicate a low incidence of CDI. Multicenter studies are needed to elucidate the burden to CDI in the country.
