Chain of Infection

You should always make sure that you wash your hands so that infections like MRSA do not spread.

These microorganisms are transmitted from poor hand hygiene from health care workers to patients as well as touching of contaminated equipment and environmental surfaces. Microorganisms are most commonly introduced to susceptible sites such as open wounds or other portals of entry by contaminated hands. Infection leads to adverse clinical outcomes and can directly threat patient recovery.

There are several important steps in preventing the spread of MRSA: washing hands before and after patient contact, using gloves appropriately, covering any cuts on the hands, maintaining healthy hands, avoiding overcrowding in hospital departments, maintaining a clean environment, and prudent antibiotic prescribing (3). Hand washing is the most effective way to keep from spreading infections. The CDC recommends that you spend 20 seconds scrubbing your hands with soap while washing your hands (1). You can sing the “Happy Birthday” song twice all the way through also (1). If soap and water are not available, the CDC recommends using an alcohol-based hand sanitizer that is at least 60% alcohol (1). This should not be used as a first line of defense. Hand washing is always the best way to get rid of harmful bacterium. Gloves and gowns are another great way to create a barrier between you and the bacteria. Proper removal of gloves and gown are vitally important. If your gloves are contaminated with MRSA, and you remove them improperly, you have completely defeated the point of even putting the gloves on. Once a surface is contaminated with MRSA, it can live prolonged periods of time unless removed through cleaning (5). For contaminated surfaces, you would want to use a disinfectant. Choosing the proper disinfectant, along with following the directions of use on the packaging, will rid the surface form microbes. It is extremely important to follow the directions on the packaging of the disinfectant because each disinfectant is different. One may need you to keep the surface wet for 2 minutes, while the other requires the surface to be kept wet for 10 minutes. If the surface isn’t kept wet for the allotted time, the surface will not be disinfected and will continue to contaminate

In the last decade, the number of prescriptions for antibiotics has increases. Even though, antibiotics are helpful, an excess amount of antibiotics can be dangerous. Quite often antibiotics are wrongly prescribed to cure viruses when they are meant to target bacteria. Antibiotics are a type of medicine that is prone to kill microorganisms, or bacteria. By examining the PBS documentary Hunting the Nightmare Bacteria and the article “U.S. government taps GlaxoSmithKline for New Antibiotics” by Ben Hirschler as well as a few other articles can help depict the problem that is of doctors prescribing antibiotics wrongly or excessively, which can led to becoming harmful to the body.

Touching objects, such as public phones or doorknobs, that have MRSA bacteria on the surface.

Methicillin-resistant Staphylococcus aureus, or more commonly, MRSA, is an emerging infectious disease affecting many people worldwide. MRSA, in particular, is a very interesting disease because although many people can be carriers of it, it generally only affects those with a depressed immune system; this is why it is so prevalent in places like nursing homes and hospitals. It can be spread though surgeries, artificial joints, tubing, and skin-to-skin contact. Although there is not one specific treatment of this disease, there are ways to test what antibiotics work best and sometimes antibiotics aren’t even necessary.

Antibiotics, composed of microorganisms such as streptomycin and penicillin, kill other infectious microorganisms in the human body. At one point, antibiotics were considered to have “basically wiped out infection in the United States”, but due to their overuse and evolutionary

Health care providers and visitors are required to wear personal protective equipment (PPE) and follow strict hand hygiene procedures. Contaminated rooms, surfaces, and laundry items are properly disinfected to prevent the spread of MRSA. In addition to policy and procedures, patient teaching is also helpful for preventing exposure and spread of MRSA. As aforementioned earlier, hand hygiene is key to prevent exposer or transmission of the bacteria. To properly wash your hand effectively, first scrub hands rapidly for at least 15 seconds. Next, use a disposable towel to dry them and another towel to turn off the faucet. In addition, hand sanitizer that contains 62 percent or more of alcohol may be an adequate substitute when the individual does not have access to soap and water (Mayo Clinic Staff,

Antibiotics are inarguably one of the greatest advances in medical science of the past century. Although the first natural antibiotic Penicillin was not discovered until 1928 by Scottish biologist Alexander Flemming, evidence exists that certain plant and mold growths were used to treat infections in ancient Egypt, ancient India, and classical Greece (Forrest, 1982). In our modern world with the advent of synthetic chemistry synthetic antibiotics like Erithromycin and its derivative Azithromycin have been developed. Antibiotics have many uses including the treatment of bacterial and protozoan infection, in surgical operations and prophylactically to prevent the development of an infection. Through these applications, antibiotics have saved countless lives across the world and radically altered the field of medicine. Though a wonderful and potentially lifesaving tool, antibiotic use is not without its disadvantages. Mankind has perhaps been too lax in regulation and too liberal in application of antibiotics and growing antibiotic resistance is the price we must now pay. A recent study showed that perhaps 70% of bacterial infections acquired during hospital visits in the United States are resistant to at least one class of antibiotic (Leeb, 2004). Bacteria are not helpless and their genetic capabilities have allowed them to take advantage of society’s overuse of antibiotics, allowing them to develop

Residents who are infected with MRSA, or similar superbug are treated with standard contact precautions while being given their medications.These include:

MRSA is spread by contact, so for example, touching another person who has it on the skin, or by touching objects the bacteria has transferred to. These particular infections are frequent amongst those with weak immune systems and those in hospitals, nursing homes, care centers, etc., because the superbugs crop up around surgical wounds or invasive devices such as catheters or implanted feeding tubes. The

Hand hygiene has been stated as the one main element that can prevent the spread of MRSA (Gould 2002). Washing hands is not kid’s stuff – not in the era of MRSA. Once entrenched MRSA can be extremely difficult to treat. If it gets into the blood stream it can be lethal (Belkum, Verbrugh 2001). Simor and Andrew (2001) also emphasise that hand washing is the most important control practice. It is essential because personal contact is the primary mode of MRSA transmission. Therefore good hand washing technique is vital to ensure that the decontamination is effective, as no soap will be effective if the technique is poor.

Carla, your post on community acquired MRSA infection, detection, and treatment of the condition is spot on. We all walk around with a variety of bacteria on our skin, especially healthcare workers. As healthcare professionals we are in constant contact with patients with various skin conditions including MRSA so it important to follow guidelines set by our institutions to limit the exposure to ourself and other patients. In addition, to the demographic that you mention in your post at risk for acquiring MRSA, younger non-exposed hospitalized patients are at risk as well.

Both health care-associated and community-associated strains of MRSA still respond to certain antibiotics. In some cases, antibiotics may not be necessary. For example, doctors may drain a superficial abscess caused by MRSA rather than treat the infection with drugs. In the hospital, people who are infected or colonized with MRSA often are placed in contact precautions as a measure to prevent the spread of MRSA. Visitors and health care workers caring for people in isolation may be required to wear protective garments and must follow strict hand hygiene procedures. Contaminated surfaces and laundry items should be properly disinfected. Preventing MRSA includes careful hand washing remains your best defense against germs. Carry a small bottle of hand sanitizer containing at least 62 percent alcohol for times when you don't have access to soap and water. Keep cuts and abrasions clean and covered with sterile, dry bandages until they heal. The pus from infected sores may contain MRSA, and keeping wounds covered will help prevent the bacteria from spreading. Avoid sharing personal items such as towels, sheets, razors, clothing and athletic

As nurses, taking care of patients with MRSA can be seen in everyday practice. It can be seen in patients with sepsis from an infected wound, patients who have pneumonia, or patients who only have a colonization for it (“Methicillin-resistant Staphylococcus aureus (MRSA), 2015”). Regardless if it’s colonization or an active infection, and the source of the infection, proper policies and procedures are in place to reduce the transmission of MRSA to other patients in the hospital or nursing home setting. This includes performing proper hand hygiene and standard precautions, as well as wearing protective gown and gloves when entering the patient’s room. It is very important to adhere to these policies and procedures and educate others on the importance of these policies and procedures to reduce the transmission of MRSA to others.
