Frequently Asked Questions

What is a Surgical Site Infection (SSI)? A SSI occurs at the site of a surgical incision. Germs can get into the incision area, and cause an infection. It can develop within 30 days of an operation, or sometimes even up to one year if an implant (such as a knee or hip joint implant) is used. Infections can be minor, or occasionally they can increase complications that result in a longer length of stay in the hospital, or an increased readmission rate for patients. Post-operative SSIs are the most common health care-associated infections in surgical patients.
What can patients do to help reduce their chances of infection? Patients should always follow instructions given by your healthcare team. Frequent hand cleaning is a good way to prevent the spread of infection.. Hand hygiene involves everyone in the hospital, including patients.
