Methicillin-resistant Staphylococcus aureus (MRSA) - 0 views

  • Staphylococcus aureus (Staph aureus or "Staph") is a bacterium that is carried on the skin or nasal lining of up to 30 percent of healthy individuals. In this setting, the bacteria usually cause no symptoms.
  • HOW IS MRSA SPREAD?
  • By touching the skin of another person who is colonized with MRSA●By touching a contaminated surface (such as a countertop, door handle, or phone)You can develop an infection from MRSA if your skin is colonized and the bacteria enter an opening (eg, a cut, scrape, or wound) in the

  • Hospital care — Risk factors for becoming infected with hospital-associated MRSA include the following:●Having a surgical wound and/or intravenous (IV) line●Being hospitalized for a prolonged period of time●Recent use of antibiotics●Having a weakened immune system due to a medical condition or its treatment●Being in close proximity to other patients or healthcare workers who are colonized with MRSA
  • The skin may have a single raised red lump that is tender, a cluster of "pimples", or a large tender lump that drains pus (called a carbuncle). The area may enlarge and become progressively more tender, red, and swollen. The center of the raised area may ooze pus.
  • People with infections of the lung, bone, joint, or other internal areas usually require blood tests as well as imaging studies (eg, x-ray, computed tomography [CT] scan, echocardiogram).
  • Prevention in the hospital — In the hospital, MRSA is commonly spread to patients from the hands of healthcare workers. To minimize this risk, patients and family members can help to ensure that anyone who comes in contact with the patient washes their hands or uses an alcohol-based hand sanitizer before and after touching the patient. Patients with active infection should also wash their hands frequently.
  • Prevention in the community — The best way to prevent and control MRSA in the community is not clear. The United States Centers for Disease Control and Prevention has made the following recommendations [4]:●Keep hands clean by washing thoroughly with soap and water. Hands should be wet with water and plain soap and be rubbed together for 15 to 30 seconds. Special attention should be paid to the fingernails, between the fingers, and the wrists. Hands should be rinsed thoroughly and dried with a single-use towel (eg, paper towels).●Alcohol-based hand sanitizers are a good alternative for disinfecting hands if a sink is not available. Hand sanitizers should be rubbed over the entire surface of hands, fingers, and wrists until dry and may be used several times. Hand sanitizers are available as a liquid or wipe in small, portable sizes that are easy to carry in a pocket or handbag. When a sink is available, visibly soiled hands should be washed with soap and water.●Keep cuts and scrapes clean, dry, and covered with a bandage until healed.●Avoid touching other people's wounds or bandages.●Avoid sharing personal items such as towels, washcloths, razors, clothing, or uniforms. Other items that should not be shared include brushes, combs, and makeup.●Students who participate in team sports should shower after every athletic activity using soap and clean towels. Athletes with skin infections should receive prompt treatment and should not compete when they have draining or active skin infections.●People who use exercise machines at sports clubs or schools should be sure to wipe down the equipment, including the hand grips, with an alcohol-based solution after using it.

Community-Acquired MRSA Becoming More Common in Pediatric ICU Patients | Children's Hos... - 0 views

  • Once considered a hospital anomaly, community-acquired infections with drug-resistant strains of the bacterium Staphylococcus aureus now turn up regularly among children hospitalized in the intensive-care unit,
  • Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) is a virulent subset of the bacterium and impervious to the most commonly used antibiotics.
  • Most CA-MRSA causes skin and soft-tissue infections, but in ill people or in those with weakened immune systems, it can lead to invasive, sometimes fatal, infections.

  • “MRSA has become so widespread in the community, that it’s become nearly impossible to predict which patients harbor MRSA on their body,”

Hospital-acquired Methicillin Resistant Staphylococcus Aureus (MRSA) - MicrobeWiki - 0 views

  • Staphylococcus aureus is a spherical microbe and a member of the bacteria domain. This bacterium can be found naturally on the skin and in the mucus membranes of humans most importantly. In fact, Staphylococcus aureus can be found in the nostrils of up to 30% of people (1). The bacteria is spread most commonly through human contact be it hand-to-hand, from a wound secretion or mucus.
  • The majority of MRSA infections were wound infections (56.9%) with pneumonia cases being the second most common (21.0%). Potentially the most dangerous infection type, bloodstream infections accounted for 15.1% of the cases and urinary track infection accounted for 6.9%
  • Despite knowing that hospitals should prevent the spread of MRSA infections due to the risk of even further drug resistance over MSSA strains, and that hospitals can be effective in preventing the spread of MRSA infections, is it cost-effective for hospitals to implement the screening and isolation processes needed to fight the spread of MRSA (even though Staphylococcus aureus infections will undoubtedly occur in hospitals)? In other words, is the cost of hosting patients for longer periods of time, the costs associated with isolating patients

The silent epidemic: CA-MRSA and HA-MRSA - 0 views

  • MRSA has evolved unpredictable resistance and epidemiology patterns in response to decades of successful antibiotic treatments that have been prescribed in all environments and have saved millions of lives.
  • The most frequent primary diagnosis associated with other S aureus–related infections was cellulitis and abscess, followed by postoperative infection, infections from an implanted device (Fig. 1), or graft and osteomyelitis.
  • As MRSA spreads into hospitals from the community, current insurance company and proposed governmental policies that penalize the healthcare system may be inappropriate.
