Abstract

Aim of the study is to count the incidence of hospital surgical site infections in a Tertiary General Hospital in Greece. Material and methods Our study is a cohort epidemiological survey which was conducted at the interval of October 2005 until June 2006 in a Tertiary General Hospital in Greece. Totally 911 patients were included. The number of surgical operations at the period of the study was 945. Results In total were detected 61 infections of surgical site in the 945 operations (6,5 infections/100 operations). More analytically 19 in A’ Surgical Clinic (3,9 infections/100 operations) and in B’ Surgical Clinic 42 infections of surgical place (9,2infections/100 operations). Were located 19 infections of superficial incisional (31,1%),deep incisional 23 (37,7 %) and organ/space 19 (31,1%). The most common microorganisms that detected were Enterococcus faecium with 17,9%, Enterococcus faecalis with 11,8%, Escherichia coli and Pseudomonas aeruginosa with 14,5%. Totally the medium duration of hospitalization of patients with infection of surgical site was 23,3 days, while patients without infection of surgical site had medium duration of hospitalization 6,8 days and the difference between them found to be 16,5 days. Prophylactic antibiotic treatment received the 61,6% of interventions. Risk factors that affect the growth of surgical site infections were found to be statistically significant the age over 60 years, the hospitalization at ICU, the multiple operations, the ASA score of (2,3,4), the long duration of the operation, the classification of surgical wound more concretely when the wound is potentially infected, the risk index NNISS (1,2,3), the preoperative duration of hospitalization ≥48h, and the prophylactic treatment with antibiotics. From the 61 patients that developed SSI, 8 died (13,1%) and from the 876 patients that did not develop SSI, 22 died (2,5%). The factors that influence the mortality are: the age >60 years, the hospitalization in ICU, the wound, the multiple operations, the urgent operation, the ASA score (3,4-5), as well as the growth of infection of surgical site. Conclusions The rate of surgical site infections of that was found is comparable with other European studies, and higher with the results of NNISS. The pathogenic microbes that were isolated, the risk factors of growth SSI and the factors that influence the mortality are similarly with other studies. The results can also be used as benchmarking for national incidence data and for inter- and intra- hospital SSI rate comparisons.
