Abstract

Background: Clostridioides difficile infection (CDI) can be divided according to its acquisition site, health care (HC) or community (CA) associated CDI. Studies showed severe disease, higher recurrence, and mortality among HC-CDI patients, while others reported the opposite. We aimed to compare the outcomes according to the CDI acquisition site. Methods: The study analyzed medical records and laboratory computerized system data to identify patients (≥18 years old) who were hospitalized with the first CDI from January 2013 to March 2021. Patients were divided into HC-CDI and CA-CDI groups. The primary outcome was 30-day mortality. Other outcomes: CDI severity, colectomy, intensive care unit (ICU) admission, length of hospitalization, 30 and 90-day recurrence, and 90 days all-cause mortality. Results: Of 867 patients, 375 were defined as CA-CDI and 492 as HC-CDI. CA-CDI patients had more underlying malignancy (26% vs 21% P = .04) and inflammatory bowel disease (7% vs 1%, P < .001). The 30 days mortality was similar (10% CA-CDI and 12% HC-CDI, P = .5), and the acquisition site was not found to be a risk factor. There was no difference in severity nor in complications, but the recurrence rate was higher among those with CA-CDI (4% vs 2%, P = .055). Conclusions: There were no differences between the CA-CDI and HC-CDI groups regarding rates, in-hospital complications, short-term mortality, and 90-day recurrence rates. However, the CA-CDI patients had a higher recurrence rate at 30 days.
