The prevalence of chronic wounds located in the lower extremity area is high among older adults.  Not only can they be extremely deleterious and pose major health risks, they also increase socioeconomic burden because of the high expenses of wound care, long duration of healing time, increased complication rate and negative effect on patients’ and loved ones’ quality of life.  Chronic wounds are related to heightened mortality and significant morbidity because of infection, loss of ability to perform daily activities, pain, and psychosocial issues. Health care clinicians must be trained to identify and diagnose wounds, as well as provide proper management of their etiology. The four most common chronic wounds are venous leg ulcers, diabetic foot ulcers, pressure ulcers, and arterial ulcers.  Although there have been recent advances in wound care, care providers are still struggling to provide the best quality of care in this area, especially for elderly people living in nursing homes and assisted living facilities.

A recent study exploring the effectiveness of twenty-four-hour reports in infection prevention and control showed that they are essential components. Infections are known to be highly prevalent among nursing home residents and can lead to morbidity and mortality. This fact is unsurprising, considering that residents are constantly clustered in constrained living environments and frequently perform daily activities in groups. Residents with impaired cognitive functioning may have difficulty engaging in fundamental hygiene practices. Far too many caregivers receive deficient training and lack the knowledge necessary to implement basic infection control. Because residents are physiologically aged and often carry comorbid diseases, not only do site-specific infections develop easily, they are also difficult to diagnose. Consequently, identification and treatment can be delayed.

Summerlin Hospital, located in Las Vegas, is currently being sued by former patients, visitors, and employees for negligence. Those bringing suit are claiming that the hospital failed to take precautionary measures, endangering the health and lives of staff, patients, and others by exposing them to a woman and at least one baby infected with tuberculosis. Tuberculosis is a common, yet potentially lethal disease which generally attacks the lungs and other parts of the body. It is contagious and may be spread through the air when someone with a tuberculosis infection transmits respiratory fluids into the air by sneezing, speaking, singing, or coughing. Due to its contagious nature, those who are in close or frequent contact with an individual with tuberculosis will be at a high risk of contracting the infection themselves.

In this case, the infected woman gave birth to twin daughters at the hospital. Despite exhibiting symptoms of tuberculosis, the woman was allowed continued visitation after being discharged in order to see her babies. The woman and both babies have since passed away from the disease, and the woman was diagnosed with tuberculosis in an autopsy. This lawsuit follows another lawsuit filed by the woman’s family, which alleges that the hospital failed to see and address signs that could have saved the woman’s life. Those bringing this claim are alleging that the hospital was negligent in its failure not only recognize and diagnose the woman’s tuberculosis, but in its failure to take basic precautionary measures. The lawsuit alleges that the hospital not only failed to warn people of a potential exposure to the infection, but also failed to follow isolation procedures.

Lysostaphin is a natural enzyme that functions as an antibacterial against staphylococcal infections including Staphylococcal aureus and Staphylococcal epidermidis. It is effective against combating these infections because it attacks the bacterial cellular wall of staphylococci, and is capable of destroying the bacterium within minutes. Staphylococcal aureus infections, particularly MRSA (methicillin-resistant Staphylococcal aureus), are a continuing concern within healthcare settings. This is because they are responsible for a large portion of infections which arise from implantable devices such as catheters, which act to provide a pathway for MRSA to travel into the body. While anyone may contract a staphylococcal infection, they are of particular concern within certain groups such as those residing in nursing homes. The elderly population is generally at higher risk due to their vulnerable state and weakened immune systems. Contraction of such infections not only lead to skin infections, but when the bacteria enters the bloodstream, it may spread into other organs, infecting them, and may also lead to sepsis, pneumonia, and other severe complications including death.

MRSA bacterial cells are capable of forming a community of bacterial cells, known as biofilms, on medical devices and damaged tissue, thereby surviving and spreading infection. Unfortunately, the biofilms that form on such devices are generally antibiotic resistant, and it becomes increasingly difficult to treat the infection. As a result, the device will either have to be removed or replaced via surgery, and the patient will require an intensive antibiotic treatment plan. However, subjecting the patient to this type of invasive procedure heightens their risk for further complications. Additionally, despite this course of action, infection reoccurrence is still relatively high due to the increasing antibiotic-resistant nature of the bacterium. Therefore, lysostaphin has been studied and considered as an alternative anti-staphylococcal treatment. This is because lysostaphin has been known to effectively destroy staphylococcal bacterial cells, and has been demonstrated to be particularly effective against MRSA.

All elderly individuals residing in nursing homes are highly susceptible to healthcare-associated infections (HAIs), a significant cause of fatalities and needless suffering. Common healthcare-associated infections include urinary tract infections, skin infections such as pressure ulcers, pneumonia, influenza, scabies, and methicillin-resistant Staphylococcus aureus (MRSA). These infections are known as healthcare-associated infections (HAIs) because they are typically acquired by patients who are receiving treatment for an initial ailment while at a healthcare setting, such as a nursing home, urgent care center, or hospital.

According to the Centers for Disease Control and Prevention (CDC), about 1 in every 20 hospitalized patients will acquire a healthcare-associated infection during their stay. These patients, particularly those who are elderly, are already in a much weakened clinical condition. Therefore, they are at a higher risk of contracting an HAI resulting in complications and even death. Thus, it is extremely important that these patients receive high-quality and safe care within these facilities. Caretakers must be aware of an elderly patient’s susceptibility to HAIs and therefore should take preventative measures to protect against them.

Generally, when an HAI is detected, the cause of the infection must be identified by healthcare providers. After, they will need to assess which antibiotic treatment, duration, and dosage will be proper in an individual patient’s case. However, caretakers should not rely on antibiotics to fix the problem. Rather, they should first implement preventative practices to avoid the infection from arising in the first place, as many of these infections are preventable.
