This information explains multidrug resistant organisms (MDROs), including how they are spread and how MDRO infections are treated.
What is a multidrug resistant organism?
A multidrug resistant organism (MDRO) is a germ that is resistant to many antibiotics. If a germ is resistant to an antibiotic, it means that certain treatments will not work or may be less effective.
MDROs can be difficult to treat since many antibiotics won’t work to treat them.
Examples of MDROs include:
- Methicillin resistant Staphylococcus aureus (MRSA)
- Vancomycin resistant Enterococcus (VRE)
- Resistant Acinetobacter
These germs can cause illnesses, including:
- Urinary tract infections
- Blood infections
- Wound infections
How are MDROs spread?
Most MDRO infections are spread by direct contact with an infected person’s bodily fluids, such as blood, drainage from a wound, urine, bowel movements (stool), or sputum (phlegm). They can also be spread by contact with equipment or surfaces that may have the germ on them. Casual contact, such as touching or hugging, does not spread MDROs.Back to top
Who is at risk for an MDRO infection?
You’re more likely to get an MDRO infection if you:
- Are older
- Have a weakened immune system
- Have chronic illnesses, such as cancer or diabetes
- Have been treated with antibiotics in the past
- Had a recent surgery
- Have had repeated or long stays in the hospital
- Have open wounds or sores
- Have tubes or drains in your body
What are the symptoms of an MDRO infection?
Your symptoms will depend on the location and type of infection you have.Back to top
How is an MDRO infection treated?
MDRO infections are treated with antibiotics that the germ causing your infection isn’t resistant to. Your doctor will decide which medication(s) to give you based on the germ and location of your infection.
What isolation precautions are taken in the hospital if I have an MDRO infection?
Isolation precautions are steps we take to stop infections from spreading from person to person. If you’re diagnosed with or exposed to an MDRO infection while you’re in the hospital:
- You will be placed in a private room.
- The door to your room must remain closed at all times.
- A sign will be posted on your door telling all staff and visitors to clean their hands with soap and water or an alcohol-based hand sanitizer before going into and after leaving your room.
- All staff and visitors will need to wear a yellow gown and gloves while in your room. These are available outside of your room and can be disposed of inside your room.
- If you leave your room for tests, you must wear a yellow gown and gloves, or be covered with a clean sheet.
- If you leave your room to walk around the unit, you must wear a yellow gown and gloves.
- You will not be able to go to the following areas of the hospital:
- Pantry on your unit
- Recreation center on M15
- Pediatric recreation areas on M9
- Main lobby
- Any other public area of the hospital
- You can have art or massage therapy in your room while following isolation precautions.
You can stop following these precautions after you received treatment and no longer have symptoms.Back to top
What precautions should I take at home if I have an MDRO infection?
Be sure to do the following at home:
- Wash your hands frequently with soap and water, especially after using the bathroom.
- Wash your hands after having contact with blood, urine, or drainage from a wound.
- Use a disinfectant (such as Clorox® or Lysol®) to wipe any surface that may have come in contact with the germ, such as your doorknob.
