Surgical Site Infections

Frequently Asked Questions

  • What is a Surgical Site Infection (SSI)?
    A surgical site infection is an infection that happens after surgery in the part of the body where your surgery took place.
  • How common is an SSI?
    Most patients do not get infections, but one to three out of every 100 patients get an infection after having a surgery.
  • What are some common symptoms of an SSI?
    • Redness and pain around the area where you had surgery
    • Cloudy fluid that drains from your surgical wound
    • Fever
  • Can an SSI be treated?
    Most SSIs can be treated with antibiotics, but sometimes patients with an SSI need another surgery to treat the infection.
  • What does the hospital do to prevent SSIs?
    ​Your doctors, nurses and other health-care providers take these steps to prevent an SSI:
    • Clean their hands and arms up to their elbows with an antiseptic agent before starting the surgery
    • Clean their hands with soap and water or an alcohol-based hand rub before and after caring for patients
    • May remove some of your hair before surgery with electric clippers if the hair is in the same area where surgery will occur.
    • Wear special hair covers, masks, gowns and gloves during surgery to keep the surgical area clean
    • May give you antibiotics to start taking 60 minutes before surgery and to stop taking 24 hours after surgery
    • Clean the surgery site with a special germ-killing soap
  • What can I do to help prevent an SSI?
    ​Before your surgery:
  • Tell your doctor about any health problems you may have. Allergies, diabetes and obesity may affect your surgery and treatment.
  • Quit smoking. Patients who smoke may get more infections. Talk to your doctor about how to quit.
  • Do not shave near your surgery site. Shaving with a razor can bother your skin and make it easier to get an infection.

    ​At the time of your surgery:
    • Speak up if someone tries to shave you with a razor before surgery. Ask why you need to be shaved with a razor and speak with your doctor if you have any concerns.
    • Ask if you will be given antibiotics before surgery.

After your surgery:

  • Make sure your health-care providers clean their hands with soap and water or an alcohol-based hand rub before they examine you. If you do not see your care team clean their hands, please ask them to do so. 
  • Family and friends should not touch your surgical wound or dressings.
  • Family and friends should clean their hands with soap and water or an alcohol-based hand rub before and after they visit you. If you do not see them cleaning their hands, please ask them to do so.
  • What do I need to do when I go home from the hospital?
    • Your doctor and nurse will explain what you need to know about your wound care before you leave the hospital.
    • Please make sure you understand how to care for your wound.
    • Clean your hands before and after caring for your wound.
    • Before you leave the hospital, make sure you know whom to call for questions and concerns after you get home.
    • If you have any symptoms of infection (redness and pain at the surgery site, drainage or fever), call your doctor right away.
