Methicillin-Resistant Staphylococcus Aureus (MRSA): Difference between revisions

Latest revision as of 13:15, 30 August 2025

Background

Two kinds of MRSA:
- Hospital acquired-MRSA (HA-MRSA)
  - Multi-drug resistant, most commonly seen in ventilator associated pneumonia, post operative infections, and catheter associated infections
- Community acquired-MRSA (CA-MRSA)
  - Tends to be resistant to beta-lactams, most commonly seen in Skin and Soft Tissue Infections and rarely in necrotizing pneumonia

Risk Factors

Multiple skin sites
Recurrent infection
Close contact of person with Hx of MRSA
Infection showing early necrosis

Management

Treatment/resistance is different for each type; check specific page

-# good hand hygiene
+*Treatment/resistance is different for each type; check specific page
-# avoid sharing personal items with carriers
-# wash common household items with bleach and hot water
-# wash soiled sheets, towels, clothes in hot water with bleach and dry in hot dryer
-# Eradicate carriers:
-# mupirocin 2%: apply to each nostril TID x 5days
-# Hibiclens wash daily x 5 days
-# consider oral antibiotics

-# Antibiotics
+{{#ask:[[Has MRSA::S]] |format=ul }}
-## [[Cephalexin]] + [[Bactrim DS]]
-###Estimated 95-100% sensitivity of CA-MRSA
-## Clindamycin
-###Approximately 50% sensitivity to CA-MRSA
-###Inducible resistance by erythromycin in laboratory, unclear significance
-## doxycycline
-###Contraindicated in pregnant females and children due to deposition in teeth and bones
-## [[Vancomycin]] IV if severe infection/sepsis
-##Linezolid
-###Indicated in severe soft tissue infections and pneumonia thought to be caused by CA-MRSA or HA-MRSA
-# I&D if abscess
-##(antibiotics not needed if no e/o cellulitis)
