<h3>Slide 2</h3>

<p><span><img alt="Text description is below the image" border="0" src="ncmrsaapdpt1Slide2.jpg" title="Text description is below the image" /></span></p>
|
||
<p><strong>MRSA: Epidemiology & Treatment: Points of this Talk</strong></p>
|
||
<ul>
|
||
<li>MRSA is primarily healthcare-associated.</li>
|
||
<li>Community-acquired MRSA think skin infections.</li>
|
||
<li>Drainage: "not just a good idea, it's the law".</li>
|
||
<li>If you can culture it, you should.</li>
|
||
<li>Fever + skin infection = blood culture.</li>
|
||
<li>Pos blood cultures for <em>S. aureus</em> = admission.</li>
|
||
<li>In 2009, Empiric Rx for skin should cover MRSA.</li>
|
||
<li>For non-cultured skin, consider Septra + Beta lactam.</li>
|
||
</ul>

|
||
<p><strong><em>Staphylococcus aureus</em></strong></p>
|
||
<ul>
|
||
<li><em>Staphylococcus aureus</em>: common cause of infection in the community</li>
|
||
<li>Methicillin-resistant <em>Staphylococcus aureus</em> (MRSA):
|
||
<ul>
|
||
<li>Increasingly important cause of healthcare-associated infections since 1970s</li>
|
||
<li>In 1990s, emerged as cause of infection in the community</li>
|
||
</ul>
|
||
</li>

|
||
<p><strong>A Single Pulsed-Field Type (USA300) has Accounted for Most Community-Associated MRSA Infections in the U.S.</strong></p>
|
||
<ul>
|
||
<li>Pneumonia (AL, AR, IL, MD, TX, WA)</li>
|
||
<li>Missouri, California, Pennsylvania, and Colorado athletes</li>
|

</ul>
|
||
<p>USA300 covers about 90 percent of the chart. The two strains below cover about 10 percent of the chart.</p>
|
||
<ul>
|
||
<li>USA100—hospital strain</li>
|
||
<li>USA200—hospital strain</li>

<p><strong>Outbreaks of MRSA in the Community</strong></p>
|
||
<ul>
|

|

<li>Other IV agents may be appropriate. <strong>Consult an infectious disease specialist.</strong></li>

<p><strong>Screening and Decolonization</strong></p>
|
||
<ul>
|
||
<li>In general, colonization cultures of infected or exposed persons in community settings are not recommended. (May have a role in public health investigations).</li>
|
||
<li>Decolonization regimens:
|
||
<ul>
|
||
<li>May have a role in preventing recurrent infections (more data needed to establish efficacy and optimal regimens for use in community settings).</li>
|
||
<li><em>After treating active infections and reinforcing hygiene and appropriate wound care,</em> consider consultation with an infectious disease specialist regarding use of decolonization when there are recurrent infections in an individual patient or members of a household.</li>

|
||
<p><strong>Preventing Transmission</strong></p>
|
||
<ul>
|
||
<li>Persons with skin infections should keep wounds covered, wash hands frequently (always after touching infected skin or changing dressings), dispose of used bandages in trash, and avoid sharing personal items.</li>
|
||
<li>Uninfected persons can minimize risk of infection by keeping cuts and scrapes clean and covered, avoiding contact with other person's infected skin, washing hands frequently, and avoiding sharing personal items.</li>

|
||
<p><strong>Preventing Transmission</strong></p>
|
||
<ul>
|
||
<li>Exclusion of patients from school, work, sports activities, etc. should be reserved for those that are unable to keep the infected skin covered with a clean, dry bandage and maintain good personal hygiene.</li>
|
||
<li>In general, it is not necessary to close schools to "disinfect" them when MRSA infections occur.</li>
|
||
<li>In ambulatory care settings, use standard precautions for all patients (hand hygiene before and after contact, barriers such as gloves, and gowns as appropriate for contact with wound drainage and other body fluids).</li>

<p><strong>Conclusions</strong></p>
|
||
<ul>
|
||
<li>New strains of MRSA have emerged in the community, with implications for management of skin infections and other staphylococcal infections.</li>
|
||
<li>Incision and drainage remains a primary therapy for purulent skin infections.</li>
|
||
<li>Oral treatment options are available for patients with skin infections that require ancillary antibiotic therapy.</li>
|
||
<li>Patient education on proper wound care is a critical component of case management for patients with skin infections.</li>
|
||
<li>Strategies focusing on increased awareness, early detection and appropriate management, enhanced hygiene, and maintenance of a clean environment have been successful in controlling clusters / outbreaks of infection.</li>
