What is it?
MDROs are microorganisms resistant to treatment with multiple antimicrobial medications.
Common examples:
- MRSA: Methicillin-resistant Staphylococcus aureus.
- VRE: Vancomycin-resistant enterococci.
Colonization vs. Infection: - Colonization: Organism is present without causing illness.
- Infection: Organism causes tissue damage or illness.
Why does it matter?
- Resistant infections can be difficult to treat.
- Vulnerable residents may develop serious complications.
- MDROs can spread through contact with contaminated hands, equipment, and surfaces.
Risk factors: - Recent or prolonged antibiotic exposure.
- Extended healthcare stays.
- Wounds or indwelling medical devices.
- Weakened immune system or chronic illness.
What should I look for?
MRSA:
- May colonize skin or the nose without symptoms.
- Infection may cause redness, swelling, pain, or drainage.
VRE: - May colonize the gastrointestinal tract without symptoms.
- Can cause urinary, wound, or bloodstream infections.
General concerns: - Fever or new signs of infection.
- Wound changes or unusual drainage.
- New changes in resident condition.
What should I do?
- Follow required infection-control precautions.
- Perform hand hygiene consistently.
- Use PPE according to facility instructions.
- Clean and disinfect shared equipment appropriately.
- Report concerning changes to the nurse.
