Staphylococcus Epidermidis Essay
Staphylococcus epidermidis is the organism that was identified based on the tests that I had conducted. The tests that I used to identify this organism were the coagulase test and the catalase test. My bacterium was beta hemolytic as well. First, a gram stain had to be done to determine whether the organism was a gram positive organism or a gram negative organism. This determined which set of tests that had to be done. My bacterium turned out to be gram positive. When conducting these tests, I only had to do the coagulase test and the catalase test because when doing the catalase test, the reaction was that it had bubbled. If it did not bubble, or have a positive reaction, then I would not have had to do the coagulase test. Also, since my bacterium caused a positive catalase test, I only had to do the coagulase test and no other tests. This is because with staphylococcus organisms, these are the only tests …show more content…
Staphylococcus epidermidis is an opportunistic pathogen, meaning that they can cause infection more frequently and more easily in persons’ with a weakened immune system such as, HIV patients (CDC, 2015). This organism is seen primarily in nosocomial infections, also known as, hospital-acquired infections (Bukhari, 2004). This means that the organisms favors the hospital environment and is easily passed to a person while they are in the hospital. Ways that a person can get a Staphylococcus epidermidis infection is through IV’s, more commonly in drug users, catheters, and artificial equipment (Bukhari, 2004). Skin-to-skin contact can also be a form of getting this type of infection. The people that are most susceptible to get Staphylococcus epidermidis are newborns, the elderly, immunocompromised patients, and patient’s who are using a catheter. This is because newborns and the elderly do not have as strong of immune systems as children and middle-age adults

Health Care Associated Infections
1529 Words | 7 PagesDepartment of Health and Human Services established an objective for Healthy People 2020 to prevent HCAIs, this reflects that the U.S. health care system is committed to and serious about solving this issue. These objectives address two extremely important topics, central line-associated bloodstream infections, and methicillin-resistant Staphylococcus aureus (MRSA) infections. Also, there are other major causes of HCAIs that Health and Human Services is working on their prevention such as urinary tract infections (UTIs) associated with catheters, infections of surgical wounds and sites, C. difficile infections, and ventilator-associated Pneumonia. Researches done on HCAIs shown that we can prevent many of these infections by implementing effective strategies to eradicate it, adapting some advanced prevention tools, and following new prevention approaches. There should be a more focus on HCAIs prevention in acute care settings.
Unit 8 H1n1
671 Words | 3 PagesThe primary prevention is the best way to eliminate the potential for exposure. Since hand washing is the most effective mean of spread of infection, it would be my primary goal to increase the compliance of hand hygiene among healthcare workers, but also an extensive education of patients and family members on hand washing before and after touching the patient as well as afar any contact with any potentially contaminated materials (surface, body fluids or respiratory secretions). Mandatory education of patients, visitors and healthcare workers, across the system as well as cross department compliance practices are single best mean of preventing the spread of infection. For example, every patient and family member can be educated about hand hygiene, use of PPE-personal protective equipment (face mask, gowns and gloves). Although, the practices are already being utilized, I believe the compliance is poorly monitored.

Perineal Care Observation
1582 Words | 7 PagesIn all areas of healthcare, particularly in acute care settings, patients may be unable to care for their nutritional and/or hygienic needs properly. One area that is especially important to address is the perineal care of patients who are incapacitated, or otherwise unable to care for their hygienic needs independently.

For example, a common cause of urinary tract infections (UTI) is due to Escherichia coli from the colon coming into contact with the urethra (Copstead & Banasik, 2013). If the patient is immunocompromised, elderly, sedentary, or otherwise compromised in their abilities to void, this can predispose the patient
Handwashing Research Paper
884 Words | 4 PagesOne of these interesting facts being that although there have been advancements in education, modern plumbing,and emerging challenges related to increasing antibiotic resistance, physicians of all people are resistant to the most fundamental infection control practice being hand washing. I also found it interesting that in 1992, The News England Journal of Medicine reported on a hand-washing study in an intensive-care unit. Despite special education and monitored observations, handwashing rates were as low as 30% and never went above 48%. I also learned that over 2,000,000 hospital patients acquire some type of nosocomial infection each year in the US alone, at an annual cost of over $45 billion. Another fact I learned is that hospital personnel can also get nosocomial infection, and in 1993 11 health-care workers became ill with hepatitis A because they didn't wash their hands after treating one of two patients with hepatitis A.
• Assess The Importance Of Proper Hand Washing In The (Nicus)
724 Words | 3 PagesHand Hygiene in Healthcare Healthcare associated infections are extremely problematic within neonatal intensive care units (NICUs), further resulting in morbidity and mortality (Kramer et al.,2017). Adherence to proper hand hygiene has shown to be effective in the prevention of pathogens, being transferred between a healthcare worker (HCW) and patient (Chhapola & Brar, 2015). Newborns are highly susceptible to healthcare associated infections due to underdeveloped immune and integumentary systems. Numerous factors contribute to poor hand hygiene; therefore, it is crucially important to minimize the spread of infection in the best ways possible. The purpose of this paper is to recognize the importance of proper hand hygiene in the (NICUs), they are as follows: application time of hand washing, the efficacy of hand rubs and compliance.
