Clostridium difficile-associated diarrhea in the clinical center of vojvodina, Serbia, in the period 2008 to 2012

Abstract

Abstract - Clostridium difficile-associated diarrhea (CDAD) has been recognized as the leading cause of diarrhea worldwide. In the last five years, it has become the leading cause of diarrhea in the Clinical Center of Vojvodina (CCV) as well. The aim of this study was to determine the epidemiology and total cost of treatment for all patients with Clostridium difficile-associated diarrhea hospitalized at the Infectious Disease Clinic of the CCV; to analyze the costs of treatment with regard to therapeutic approach; to compare the costs of treatment in each year of the investigated period related to the number of patients, and to analyze the outcome of treatment. The study was retrospective, and the data were collected from the medical records of 472 patients with Clostridium difficile diarrhea treated from 2008 to 2012 and analyzed. Of the total 472 patients with CDAD, 54.23% were female and the average age was 65.84. A statistically significant majority of them had been previously treated in other hospitals and a minority in ambulatory settings (395 inpatients vs. 77 outpatients, p=0.000, p<0.05). Of the 395 previously hospitalized patients, most were from the Clinic of Urology of the CCV (58, 14.68%). When comparing therapeutic options, oral vancomycin was significantly more frequently used than other protocols. The average mortality rate during the study period was 6.51%. In this period, total hospital costs related to Clostridium difficile diarrhea in the Infectious Disease Clinic were $636,679.92. Implementation of infection-control measures and a restricted use of antibiotics would result in a great reduction in material costs.
