Abstract
Background: The surgical wound infections (SWI) are common in hospitals, depending on the type of surgery and the presence of risk factors, cancer patients have a higher prevalence of infection, (immune-compromised state in which it is located). A low rate of infection is one parameter to measure the quality of surgical services. The aim of the present work was to determine the epidemiological characteristics of SWI in cancer patients in the Jaliscience institute of cancerology.
Study Design: A descriptive, retrospective study.
Methodology: 46 patients were studied with SWI. Centers of disease control and prevention criteria for surgical wound infection were considered. Information was obtained from the Jaliscience Institute of Cancerology epidemiological department, using the hospital network for epidemiological surveillance (HNES) format record´s, included microbiological results and clinical data. The statistical analysis were performed with the SPSS-20 program.
Results: There were 2637 major surgeries from April 2008 thru December 2010. 46 had SWI. Frequency of service per 100 infected surgeries was: Gastroenterology 58.6%, Gynecology 32.6%, Urology 4.4, Head and Neck 2.2% and Traumatology 2.2%. Incidence by gender: men (1.1), women (0.83), with no significant difference. Average age of 51 years. The surgical-wound infected (SWI) were detected between 7.4±4.2 days. Average days stay 19 days. The results of microbiology cultures exhibited: Escherichia coli 53.3%, Pseudomonas aeruginosa 11.9%, Morganella morganii 4.8%, Enterococcus faecium 11.9%, Enterococcus faecalis 23.8%, Staphylococcus-coagulase-negative 7.1%, Streptococcus ß-hemolytic 4.8%.
Conclusion: Surgical wound infection rates were similar to that reported in other countries and below the rates reported in oncology hospitals in México. It is important to note that a proper preventive approach and epidemiological surveillance are critical to avoid mortality of patients.
