Abstract

Clostridioides difficile infection (CDI) is a major cause of healthcare-associated diarrhea. This study aimed to analyze the clinical course and characteristics of patients diagnosed at a tertiary university hospital in northeastern Romania between 2020 and May 2023. Materials and methods: This retrospective observational study included 2,317 adult patients with CDI confirmed clinically and microbiologically, colonoscopically, or histopathologically, who were hospitalized between January 2020 and May 2023. Data from medical records were analyzed descriptively using SPSS 18.0, employing frequencies, percentages, and measures of central tendency and dispersion. Results: The number of CDI cases increased progressively from 2020 to 2022 (rising from 540 to 811), with 290 cases recorded between January and May 2023. Men accounted for 59.6% of the cohort; the mean age was 62.82 ± 15.67 years, with a median age of 65 years. Patients from urban areas represented 57.7% of the total. A combination of toxins A and B was identified in 79.6% of cases. Healthcare-associated CDI accounted for 50.1% of cases, and 50.5% of patients had experienced at least one hospitalization in the preceding year. Recent exposure to acid-suppressive medication was noted in 64.4% of patients, antibiotic therapy in 24.3%, and surgery within the previous two weeks in 13.4%. Immunocompromised patients constituted 55.3% of the group, and recurrence occurred in 9.5% of cases. Conclusions: The profile of patients with Clostridioides difficile infection was characterized by advanced age, prior hospitalizations, and recent exposure to acid-suppressive medication and antibiotics. The results highlight the need for active surveillance and early identification of high-risk patients to reduce the impact of CDI in the hospital setting.
