RESUMO
OBJECTIVE: To investigate possible predictors and prevalence of surgical site infections (SSIs) in a group of Mexican patients who underwent open abdominal surgery. METHODS: This retrospective study included all patients (N = 755) who underwent elective or emergency open abdominal surgeries from October 2011 to March 2012. MAIN OUTCOME MEASURE: Sociodemographic and clinical characteristics were collected through preoperative and postoperative examinations by the infection surveillance team. The relationship among variables (age, gender, body mass index, comorbidities, smoking habit, antimicrobial prophylaxis, hair removal, American Society of Anesthesiologists classification, type of operation, duration of operation, and SSI classification) was analyzed by odds ratio and χ tests. MAIN RESULTS: Of the 755 patients, 91 (12%) suffered from SSI. Several variables were associated with SSI: American Society of Anesthesiologists classification (P = .001) and receiving preoperative prophylactic antimicrobials (P < .0001), among other factors. Isolated pathogens were mostly enterobacteria (60%). CONCLUSIONS: Surveillance plays an important role in the control and prevention of SSI. Providers must implement appropriate procedures to reduce SSI after abdominal surgery.
