Leavell and Clark's Levels Of Prevention Model:
Similarities and differences to the nursing process
Although technically not a nursing theory, Leavell and Clark's 1975 levels of prevention model has been extremely influential within the healthcare field. "This model suggests that the natural history of any disease exists on a continuum, with health at one end and advanced disease at the other" (Models of prevention, 2013, Current Nursing). There are four distinct levels of application to prevent disease. On the level of primordial prevention, before the disease has appeared, children and adults are encouraged to avoid developing unhealthy lifestyles that promote diseases that may occur in the future (preventative actions include eating well and exercising and engaging in proper sanitation practices like hand-washing as well as getting regular vaccines). On a primary prevention level when the potential for a specific disease is known, the population is also encouraged to take positive steps to preserve health such as engaging in positive self-care, not engaging in destructive habits like smoking, exercising appropriate sanitation, and getting vaccinations for preventable...
This is less effective than primary prevention. It is much easier, cheaper, and more effective, for example, to not become overweight in the first place than it is to treat obesity after the fact with a highly structured low-calorie diet regime and exercise program which can be difficult for many people to adhere to regularly or to develop a new influenza vaccine. Preventing the spread of disease might include improving existing sanitation facilities, passing anti-smoking in public laws, and more widespread vaccines for unaffected members of the population (such as the influenza vaccine).
Tertiary prevention is even more costly and less effective than secondary prevention. "All measures available to reduce or limit impairment and disabilities, minimize suffering caused by existing departures from good health and to promote the patient's adjustment to irremediable conditions" (Models of prevention, 2013, Current Nursing). For obesity, this might include the treatment of type II…

Nursing Across Theories Nursing is a core concept that is common across contemporary nursing theories. Even though the definitions, applications, and philosophies are different with each theory, the concept of nursing plays a vital role in each one. Contemporary theories came about when the teaching of nursing students was not sufficient to the performances of what the nurses were being taught in schools and ultimately affecting patient care in the long
5 million U.S. patients develop HCS's that result in $5billion in costs and almost 100,000 deaths. It is amazing that in one of the most technologically advanced societies ever, 100,000 individuals lose their lives based on increased microbial and invasive infectious agents -- and that most of those affected (68%) are those that have been successfully treated for cancer (Siegel and Korniewica, 2007). Transcultural and diversity in nursing is another topic
Nursing Theories Transcultural Care For the past several decades, nursing theory has evolved with considerable considerations towards transcultural care. The concept of culture was derived from anthropology and the concept of care was derived from nursing. When one understands the derivative of nursing knowledge and the basis for cultural sensitivity, one may tailor and provide the best nursing care for diverse groups. Each group may have specific needs that may help or
According to Newman, nurses practicing within this theory find their own lives are enhanced and transformed (Neill, 2002). Her beliefs and consciousness-centered approach were born from her early nursing experiences involving rehabilitation patients (Weingourt, 1998). She came to understand the altered connection between the concept of time for her patients and their limited mobility. For most of her patients, the day would seem to drag along despite the fact
She was almost radical in her approach to healthcare and healing. By radical, I mean that she was the type of individual who aimed to solve matters by getting to the root of the problem. She was more interested in solving the problem and not the symptoms of an underlying issue. She used a systems thinking methodology that made her overall approach to healthcare a faith-based philosophy. Although she used
Advanced Practice Nursing Framework Following its introduction during the 1960s, the role of the advanced practice nurse (hereinafter alternatively "APN") has expanded greatly into a number of specialty areas (Nwosuocha, 1999). Consequently, the definition of the advanced practice nurse has also experienced significant changes. According to Nwosuocha, "With the expanded roles of advanced practice nursing there are many definitions of what constitute faculty practice. Teaching, service, joint appointments and other
