A Cure for MRSA?

MRSA infections are increasing every year, resulting in over 75,000 cases in the U.S., causing around 10,000 deaths annually, states the CDC.MRSA starts resembling a pimple, and then evolves into a red crater of blackened puss. Left untreated, MRSA can cause death (Lowie, 2015).

For almost five years Lindsey, “Les” Shaw, a microbiologist at The University of South Florida, has been researching and developing a potential antibiotic to fight MRSA (Lowie, 2015).

“In December of 2014, Shaw’s team received a patent for their modified quinazoline, a class of compounds used to treat malaria and cancer. USF chemists believe that quinazoline-based compounds have potential antibacterial properties that could effectively eradicate MRSA” (Lowie, 2015).

In light of what we know about MRSA, do you believe a antibiotic will ever be developed that will fight MRSA?  Additionally, if this antibiotic works now, do you believe it will be effective forever?

How do you keep your work area clean?

As a paramedic, I was always concerned about the cleanliness of my work environment, the ambulance.  Maybe it was because of the occasional blood stain that could be found on the wheel of the cot or a backboard strap that was missed when cleaning?  The scary part is, sometimes it’s what looks clean that isn’t clean is more of a concern.  In a study by Stevenson, Bell, Hoet, and Lu (2010), almost one third of all the ambulances in Ohio that were swabbed and cultured had invisible MRSA inside of them.  If we cant see it, how do we protect ourselves?  I always made an effort at the beginning of my shift to disinfect common areas such as the seat, steering wheel, radio, report writing area, etc. of my squad to assist in this mission.  Any thoughts on what you do in your clinical area to help protect you and your patients from invisible bugs like MRSA?

Wash your hands… or else???

Infection prevention specialists often have a more clinical point of view than frontline staff when it comes to hand hygiene (McAlearney & Hefner, 2014).  Frontline staff tend to feel that the interpersonal skills associated with hand washing education is just as important as the information itself.  McAlearney & Hefner found that a friendly face, a warm smile, and frequent repetition help frontline staff to use good hand washing techniques more frequently. What do you think about the importance of how hand washing information is communicated?  Does it matter if it’s done in a friendly and caring way, or should it be done solely by presenting the facts?  Based on how you answered, how might compliance with hand washing protocols be affected?

How often do YOU wash YOUR hands?

Healthcare workers strongly agree that preventive behaviors such as hand washing reduce the spread of MRSA (Siebert, Speroni, Oh, DeVoe, & Jacobsen, 2014).  Most healthcare workers self-report that they “almost always” wash their hands consistently, even though Siebert et al. report that anonymous observations reveal much lower rates of hand washing compliance.  Even support staff who do not have direct patient contact need to be scrupulous with their hand hygiene, because infection can be spread by using a community pen to sign a form, or by reaching over to move a trash can closer to the bed. Why do healthcare workers misrepresent the frequency with which they wash their hands?  How often do you wash your hands?

More precautions = less care?

Healthcare workers generally feel a deep sense of responsibility to patients for prevention of MRSA and other infections.  But one study shows patients who are on contact precautions receive fewer hourly visits and have less direct contact time with healthcare workers than those who are not on contact precautions (Siebert, Speroni, Oh, DeVoe, & Jacobsen, 2014).  Working with patients in isolation is reported by healthcare workers to be an on-the-job stressor and may impact the level of care that our most vulnerable patients receive.  Have you observed it to be true that patients in isolation receive less frequent contact by healthcare workers?  What might be some reasons why healthcare workers pay less attention to patients in isolation? How do you think this problem be addressed?
