Community Acquired MRSA
Community Acquired MRSAA SECOND LOOK AT HOW TO COMBAT THIS THREAT
JOHN WOODCOX RN CRRN
What is CA-MRSA?Organism presents itself primarily as a Skin and Soft Tissue InfectionsPulmonary associated infections-Necrotizing PneumoniaLess resistant to Antibiotics than its counterpart HA-MRSA
Community versus Hospital AcquiredCommunity Acquired is less resistant, More virulentPrimarily SSTIs, less often pulmonary, blood, and UTIsOther presentations include: Osteoarticular, Endocarditis, Sepsis, OsteomyelitisApproaching 155 cases per 100,00010% is acquired in homes with another infected personHospital Acquired isMore resistant and harder to treatPrimarily Pneumonia, UTI, Bloodstream
DiagnosisPulsed-Field Gel Electrophoresis Sorts isolates into categoriesDetermines CA-MRSA from HA-MRSAMore Accurately Addresses Appropriate Antibiotic
TransmissionDirect ContactPerson to PersonIndirect ContactSurfaces Harboring the OrganismDropletThrough organisms propelled into the airPrevious ColonizationBloodstream/Incision infections of the same strain
Promoting FactorsIndiscriminate Prescription of AntibioticsEducational GapsPoor HygienePoor Infection Control PracticesNonselective use of Antibiotics in LivestockOvercrowdingExtended Hospitalizations
PreventionProper Hand WashingHand SanitizersSoaps and Chemicals usedIsolationHospitals are more stringentLong term care facilities less stringentProper Isolation protocols neededEmployee proficiency with Isolation precautionsIncreased educational effort neededCommunication gaps in known carriers, active/inactive
