Introduction.

The incidence rate of surgical site infection associated with breast surgeries ranges from 6% to 38%. We present the local incidence and microbiological profile of infections in an oncology clinic.

Methods.

Prospective, descriptive cohort study over a one-year period of women diagnosed with breast cancer at Instituto Médico de Alta Tecnología, IMAT Oncomédica, and have developed surgical site infection after mastectomy.

Results.

335 registered surgeries were found. The incidence of surgical site infection was 3.38%, all of them in radical mastectomies with reconstruction. Bacterial growth was obtained in 77% of crops. Gram-positive were the main microorganisms responsible, predominantly methicillin-sensitive Staphylococcus aureus (SAMS). Gram-Negative bacilli accounted for 40%. First generation cephalosporins were administered as presurgical antibiotic prophylaxis, which was correct in 31% of cases. In 50% of infected patients, the pre-surgical bath was performed and the institutional protocol was complied with.

Conclusion.

Our incidence of surgical site infection was lower than reported in other series. SAMS was the most common responsible microorganism. Compliance with cephalosporin and pre-surgical bath prophylaxis is critical to reducing the incidence of operative site infections.
