Aim:

To describe the characteristics of elder patients diagnosed with Clostridioides (Clostridium) difficile infection in a geriatric hospital in Costa Rica.

Methods:

A retrospective observational study was done with demographic and clinical information from 141 patients admitted in the National Geriatric and Gerontology Hospital of Costa Rica from 2015 to 2018, who presented a positive immunochromatographic test for the detection of C. difficile antigen and/or toxins in diarrheic feces. Continuous variables were compared through one-way ANOVA test, while categorical variables were compared using Fisher's exact test. The risk factors for each of the groups were evaluated by univariate analysis. P values < 0.05 were considered statistically significant with 95% confidence.

Results:

We studied 141 patients with diarrhea associated with C. difficile, the average age of the patients was 83 years and 75% were women. 35% of the cases were community acquired and 27% were severe cases. Antimicrobial consumption was given mainly by cephalosporins and fluoroquinolones. Metronidazol was the most used treatment (81%) and the C. difficile associated mortality 30 days post infection was 35%.

Conclusion:

This is the first epidemiological report of C. difficile infection in elderly hospitalized population. Also, it evidences an important percentage of community acquired and severe cases, calling for the establishment of local treatment and prevention guidelines for this infection.
