[Ed. Note: We are pleased to welcome Tara J. Hopper to HRW. She is a candidate for a Master of Laws (LL.M) degree in Health Law here at Seton Hall Law, having recently graduated from Nova Southeastern University Shepard Broad Law Center, where she received her Juris Doctor with a concentration in Health Law. She also holds a Masters of Social Work (M.S.W.) with an emphasis in mental health from Barry University. She has worked as a mental health therapist, a mental health advocate and legislative advocate for the Advocacy Center for Persons with Disabilities, Inc., as well as ChildNet, Inc., and as the Senior Legislative Aide to Florida State Senator Walter "Skip" Campbell while he was acting as Senate Chair of the Committee on Children and Families. She became a strong advocate for creating awareness of, and drafting legislation to help protect patients from, methicillin resistant staphylococcus aureus (MRSA) after her best friend died of MRSA at the age of 33 in 2008. ]
On October 2, 1960, Dr. Patricia Jevons discovered new strains of Staphylococcus Aureus. These strains were later described as Methicillin Resistant Staphylococcus Aureus ( MRSA ) after being introduced through the British Medical Journal on January 14, 1961. Thus, the discovery of MRSA was fifty-one years ago this month, and the year 2011 marks the 50th anniversary of when MRSA received its name and, as such, in a sense, came into being.
Unlike other anniversaries where people come together and celebrate, October 1, 2011 marks the third year in a row where MRSA survivors, family and friends of MRSA victims, and policy-makers, gather together to promote MRSA Awareness and to remember and honor loved ones who have been lost to MRSA. World MRSA Day is October 2nd, and October has been declared World MRSA Awareness Month. The 2011 theme for World MRSA Day is “The MRSA Epidemic - A Call to Action,” and focuses on MRSA as a public health crisis.
MRSA is a bacterial infection that is resistant to penicillin type antibiotics, and for this reason, MRSA has been called a ’super-bug.’ MRSA acquired within a healthcare setting is referred to as a Healthcare-Associated Infection (HAI), if contracted within the community it is referred to as a Community Associated Infection (CA).
Risk factors for acquiring HAI-MRSA include having a history of hospitalizations or surgeries, living in a long-term care facility such as a nursing home, recent use or long-term use of antibiotics, and having had a previous MRSA infection or colonization.

Risk factors for having acquired CA-MRSA include playing contact sports, sharing equipment or towels at a gym, using illegal intravenous drugs, and living in crowded, unsanitary conditions such as a jail or other institution. Your chances are also increased for developing CA-MRSA if you do not keep a pre-existing wound covered by a bandage, or you have a weakened immune system. It is believed that approximately 1% of the community’s population are “MRSA carriers” and are unaware that they have MRSA because they do not have an infection or any MRSA symptoms. However, MRSA carriers can pass MRSA on to other people who may not have the immune system or antibiotic resistance to fight it. In addition, people who have certain illnesses such as diabetic foot ulcers and cystic fibrosis have an increased risk of death when tested positive for MRSA.
MRSA infections become invasive when the MRSA infection is isolated in an area of the body that is normally sterile such as the blood, bone, lymph nodes, brain, heart, liver, spleen, kidneys, pancreas, ovaries, and various bodily fluids. If an invasive MRSA infection is then left untreated, MRSA can spread throughout the entire body. It is unusual for MRSA to be successfully treated after it spreads to multiple parts of the body. When there is a delay in treatment for an invasive MRSA infection, the fatality rate of MRSA patients significantly increases. Early MRSA detection through mandatory screening allows for treatment of MRSA before it becomes invasive.
Some World MRSA Day activists argue that there has been such an exceptional increase in the incidence of MRSA that MRSA should be declared an ‘epidemic.’ However, MRSA has yet to be declared an epidemic by any state or federal authority. Some experts argue that when data is inadequate to determine whether or not there has been an exceptional increase in the incidence of a disease that a “clear temporal increase” in the incidence should be sufficient to declare an epidemic. Because MRSA screening and MRSA reporting requirements are not mandatory, except in a few states, it is likely that data is inadequate to determine the actual incidence of the disease.

However, recent data regarding MRSA related deaths show that The Center for Disease Control reported in 2007 that “approximately” nineteen thousand people die from MRSA every year. Other studies report that antibiotic resistant germs such as MRSA contribute to the death of approximately 70,000 hospitalized Americans each year. It is unclear, due to a lack of historical data on MRSA, to fully understand the increase in incidence, and figure out how many people need to die in order to justify MRSA being declared an epidemic.
When issues reach epidemic status, federal dollars usually follow so that proper precautions can be taken, and further research can be done to find a cure and/or remedy. With many government agencies tightening their belts across the nation, one may surmise that declaring MRSA an epidemic would be disfavored based on the funding requirements alone. Although an increase in MRSA research funding can promote the development of new antibiotics for MRSA, MRSA research funding does not appear to be a strong federal priority. In 2010, it was reported that scientists at the University of Nottingham in the UK researched cockroaches and locusts and found that tissues from their brain and nervous system of these bugs killed more than ninety percent of the MRSA in the study. Wouldn’t it be ironic if the MRSA Superbug ends up meeting its eternal demise through the use of antibiotics from actual bugs? Hopefully, through an increase in MRSA awareness, MRSA funding and research will increase so that MRSA related deaths can decrease.
Recent trends of state legislatures show both proposals and adoption of MRSA screening and reporting legislation that promote the early identification of MRSA, and preventing the spread of MRSA. Opponents of MRSA screening legislation argue that it is too costly, impractical and inconvenient. However, MRSA detection plates are available at only a little more than $1.50 per plate, and screening requires only a simple nasal swab to detect MRSA. Recent advancements in MRSA detection devices make it possible to receive test results within 50 and 75 minutes, whereas test results were previously only available within 18 to 48 hours. This shortened time in obtaining test results gives a hospital the ability to isolate and treat the MRSA patient before MRSA is spread to other parts of the hospital.
Although there are legal concerns that screening and reporting requirements may increase hospital liability in medical malpractice suits, MRSA screening upon admission would also be advantageous to hospitals in order to show that the patient had acquired MRSA before entering their facility, therefore, decreasing their opportunity for liability in these instances. MRSA reporting may initially have a negative impact on hospitals that report higher MRSA rates, but when following MRSA screening procedures and MRSA prevention guidelines such as those provided by The Society for Healthcare Epidemiology of America (SHEA), it is likely that a hospital’s MRSA numbers will significantly decrease. After the adjustment period is over, hospitals may be happy to report just how MRSA-free their facility has become, and everyone will benefit from such a decrease in this life-threatening infection.
