<p>I’ll jump in for Sunny, I’m deep into researching whether or not to begin testing for MRSA infection on admission at our hospital.</p>
<p>There is some pretty good evidence that aggressive testing, isolation, and treatment (showers with antibacterial soaps and topical, not internal antibiotics) can clear MRSA colonization, reduce transmission and infection, and possibly, over time, reduce prevalence. This is a rapidly changing situation, however, as CA-MRSA becomes more widespread, it will become harder to be certain that it is eradicated. When a person goes through the regimen of the showers and ointments and clears the MRSA, it is not known how long they remain clear, but as Sunny points out, since you can live with it in your nose quite happily, then the important time to prevent a serious infection is while the person is hospitalized or having surgery, etc. It is also unclear who of all the people admitted to the hospital, is most at risk, and most in need of testing. As I will say, logistically, it will take awhile for a hospital to ramp up and test large numbers of patients - we are considering testing everyone, and that is a large and expensive undertaking.</p>
<p>From my research, I think that it is only a matter of time until all hospitals test persons on admission for MRSA, then isolate them and try to clear the colonization. It is not happening immediately because it is a complicated process - there are at least 3 different ways to test patients, which one should a particular hospital invest in? How to retrain the staff? Where to get the isolation beds? How to educate, but not terrify the patients and families? After all, the person may be recolonized with MRSA as soon as they get out of the hospital? Should any staff be tested? On and on.</p>
<p>Finally, there is only limited evidence that the testing, cleaning and isolation works - handwashing, room cleaning, and other measures are also important. What is the best regimen? Do people need to “fumigate” their homes, or is it better to only treat colonized persons when they become at higher risk for invasive disease, ie, when they come to the hospital? What to tell coaches and athletic trainers?</p>
