Description Surgical site infection (SSI) is the most common healthcare associated infection, accounting for 30% of all nosocomial infections. of all nosocomial infections. Among the various intra-abdominal procedures, colorectal surgery has the highest rate of SSIs. Evidence shows that patients who developed SSI after colorectal surgery had a significantly longer hospital stay (8 days longer) than those who did not. who did not. In recent years, new or revised SSI prevention guidelines have been published by many organisations, such as the World Health Organization (WHO), and last year an adapted SSI prevention document was published for the Czech Republic. CZECH REPUBLIC. The aim of this retrospective study was to determine which individual factors significantly increase the risk of SSI in the surgical workplace. Methods. Results. Patient characteristics, age, sex, and American Society of Anesthesiologists (ASA) physical status classification were included, indications for surgery and mortality. Operative details included duration of surgery. All statistical analyses were performed using the R software package and its superstructure R-studio. Continuous variables were expressed as mean ± standard deviation or median (range or interquartile range [IQR]) and were compared using appropriate statistical tests, such as Student's t-test, Mann-Whitney U-test goodness-of-fit Pearson chi-square test and others. A P value <0.05 was considered statistically significant.Results: Data were obtained from the Hospital Information System (NIS). In the period 1.1.2013 - 31.12.2022, 32,932 patients were treated, of which 946 had postoperative complications in the form of wound infection. Of the total number of patients with SSI, 471 patients died, of whom 55 patients had postoperative complications related to wound infection. Deaths represented 1.4% of the total number of patients and 5.8% of patients with postoperative wound complications. SSI is statistically significant with 95% probability for length of hospital stay. The median length of hospital stay for patients with no known infection was 5 days; for patients with SSI it was 4 times longer at 20 days. An operation time longer than the value in the 3rd quartile of the distribution of operation times is a significant risk factor. is a risk factor, as is an ASA greater than 2. CONCLUSION: The implementation of clinical guidelines is necessary, but we need to know our own SSI incidence data so that we can assess whether there has been a reduction in SSIs. to assess whether there has been a reduction in the incidence of SSIs. Few studies have been done to evaluate risk factors for SSIs in the country, a situation complicated by the fact that most SSIs occur after hospital discharge and patients return for re-hospitalisation. are readmitted to hospital at different stages of SSI development.
