Clostridium difficile infection in patients hospitalized in the gastroenterology ward - retrospective analysis

Clostridium difficile associated colitis became over last years a worldwide medical issue. It involves patients of the Polish hospitals too. The aim of the study was the analysis of CDAD incidence and the course of infection in Gastroenterology Ward of Regional Specialist Hospital of Zgierz, 2012-2015.

Retrospective analysis of the medical documentation of 79 patients with CDAD was performed. Demographic and epidemiological data and the clinical course of infection were analyzed.

The study group comprised of women in 59,5% and men in 40,5%. The patients' average age was 70,5 years. The average hospitalization period was 10,3 days. CDAD infection seasonality was proved, with statistically significant peak in springtime. 73% of patients were previously hospitalized and 85% - had co-morbidities. 76% of patients underwent antibiotherapy, whilst 29% - used PPI prior to CDAD diagnosis. 50,6% of patients had severe CDAD diagnosed. The recurrence reached 14%. In 19% of patients CDAD resulted in death.

The results of the study confirm increase of the incidence of the patients with CDAD in Gastroenterology Ward over 4-years' observation. The prevalence was higher among 65+ patients, after prior hospitalization and antibiotherapy. The co-morbidities was a significant risk factor, especially common in severe cases.

The results we obtained confirm substantial importance of Clostridium difficile infection leading to antibiotherapy- associated diarrhea among adults, causing prolonged hospitalization, increased prevalence and mortality of patients. Getting to know and minimizing the risk factors will prevent the future outbreak of the disease.
