Risk factors of Clostridium difficile-associated diarrhea in hospitalized adults: Vary by hospitalized duration

2021

Background: Clostridium difficile is the leading cause of nosocomial infectious diarrhea. Hospitalized patients were at risk of C. difficile-associated diarrhea (CDAD). However the risk factors of CDAD in patients with different hospitalization period are not clear. Material and methods: A prospective investigation was conducted in medical wards of a district hospital in southern Taiwan, from January 2011 to January 2013. We arbitrary divided patients into two groups: hospitalized for at most 14 days and 15–30 days, and analyzed their risk factors for CDAD. Results: Overall 451 patients were enrolled. The multivariable analysis of 19 (8.0%) patients developing CDAD within 14 days' hospital stay and 216 patients hospitalized for ≤ 14 days without CDAD showed malignancy (odds ratio [OR] 7.15, 95% confidence interval [CI] 1.82–28.09; P = 0.005), prior cephalosporin (OR 10.8, 95% CI 1.3–93.9; P = 0.03) and proton pump inhibitor (PPI; OR 7.1, 95% CI 2.1–24.7; P = 0.002) therapy were independently related to CDAD (Table 3), but hypertension (OR 0.2, 95% CI 0.1–0.7; P = 0.01) was reversely related to CDAD. However, of 9 (4.2%) patients developing CDAD later (15–30 days' hospital stay) and 207 patients with longer hospitalization (15–30 days) but free of CDAD, malignancy (OR 14.0, 95% CI 1.6–124.9; P = 0.02) and underlying diabetes mellitus (OR 20.5, 95% CI 2.9–144.9; P = 0.002) were independent risk factors of CDAD. Conclusion: Risk factors for CDAD among hospitalized patients varied by the duration of hospital stay. Intervention strategies to prevent CDAD may be different in terms of hospital stay duration.
