One of such early interventions may be offered by Roper, Logan, Tierney (1980) called the activities of daily living model. As explained in the presentation, the model consists of an individual’s ability to carry out self-care tasks such as functional mobility, self-feeding, personal hygiene and grooming (Roper, Logan & Tierney, 1980). Thus, any change in these may be considered as a deteriorating patient.
However, this approach not only lacks objectivity, but it also fails to acknowledge the abnormal physiology that precedes this breakdown in self-care. For instance, it has been reported that 70% of patients preceding cardio-pulmonary arrest had a physiological decline in respiratory or mental function (Schein et al 1990). Observing deterioration in activities of daily living alone does not accurately mirror underlying physiological deterioration occurring in patients.
On account of theses limits other tools that are more efficient, objective and accurate are necessary to enhance acute hospital care. The National Institute for Health and Clinical Excellence (NICE 2007) have highlighted the importance of a systemic approach and advocated the use of EWS to efficiently identify and response to pa...

...ways the case as many studies have failed to validate these systems, some revealing poor sensitivity, poor positive predictive value and low reproducibility (Gao et al 2007; Smith et al 2008; Subbe et al 2007; Jansen et al 2010).
Considering the conflicting findings amongst the different EWS, it remains unknown whether these scoring systems are effective in identifying and responding to deteriorating patient in acute hospital settings. This essay intends to establish how successful, if at all, the EWS in particular SHEWS is in identifying deteriorating patients in acute surgical hospital settings. In order to do this we will be returning to patient X, a 22-year-old Asian female with a diagnosis of acute pancreatitis. By comparing the evidence base to reality I hope to get a better understanding of how effective this tool is in identifying deteriorating patients.

- Although hypersensitivity to fruits and vegetables is assumed to play a role in the etiology of asthma and deteriorating of symptoms in some asthmatic patients, however, little is known about allergy to some fruits and vegetables in patients aforementioned. The purpose of this study was to identify probable sensitization to eggplant, Shiraz grape, melon and mango among asthma sufferers. The study included 50 patients with moderate to severe persistent asthma and 50 healthy individuals with no history of asthma and other atopic diseases....

- Case Study Sickle Cell Anemia is an autosomal recessive disorder, which increases blood thickness hence affects the smooth flow of blood. This causes by the destruction of red cells where the normal shape of red cell become a stiff sickle shape. As a result, sufficient oxygen does not reach the vital organs. A vaso-occlusive crisis arises from hindrance of blood circulation by sickled blood cells. It is characterized by sturdy pains and in some cases; it may cause permanent organ damage. This paper seeks to formulate a nursing diagnosis, as well as a plan of care that includes nursing interventions and the methods to be used to evaluate whether the interventions are successful (American Sic...

- Even though many dispute over the value and usefulness of treatment and care of terminally ill patients, the debate for the most useful care and pain reliever for these patients is the question that most patients, and their families, have to ask themselves daily. Wesley J. Smith suggests that Hospice care for patients with such a horrible illness is a beneficial program and that many patients need to utilize it. Smith also recommends that a valuable care option would be to “allow the terminally ill to enter hospice care without having to give up life-extending or curative treatments”....

- It is safe to say that in the past 20 years or so, the number of cases in malpractice litigation has increased dramatically. This has had extremely adverse effects on the way doctors choose to treat their patients, the way patients view their doctors, and how society in general views the medical profession. Litigation, it seems, has become the most common response to a bad outcome. This is especially troubling since claims of malpractice generally occur when bad outcomes are combined with "bad feelings." Doctors are therefore pressured into making some sort of defensive decisions in order to protect themselves from lawsuits.... [tags: ligation, medical, insurance]

- One quiet morning, a week before high school graduation, my mother screamed my name. Something about her tone scared me, so I ran to see what the matter was. My grandfather had slid off the bed and defecated in his clothes. She thought his bowel movement was an accident and wanted me to help her get my grandfather in the shower. As I knelt to help her, I noticed the asymmetry in his face and recalled a stroke pamphlet in the doctor’s office, so I asked him to move his arms. He raised his right arm on cue, but could not move his left.... [tags: Physician, Patient, Cancer, Medicine]

- Schizophrenic patients relapse more frequently compared to other mental illnesses (Csernansky & Schuchart, 2002 ). About 70% of newly diagnosed schizophrenic patients relapse the first year and 90% the second year (Silverstein& Bellack, 2008). Schizophrenic patients experience relapse because of the insufficient outpatient healthcare model for the severely mentally ill. Outpatients care for severely mentally ill individuals lack resources necessary for adequate healthcare. In particular, caregivers lack the knowledge and skills needed to understand what the illness encompasses (Kilbourne, Greenwald, Bauer, Charns, & Yano, 2012)....

- Bioterrorism is the terrorist act of manipulating natural components to sabotage an enemy. It has been around for thousands of years, but in different forms. To take a case in point, the article, “History of Bioterrorism,” states that the Assyrians poisoned the well of their enemies with rye ergot in the 6th Century B.C. More recent examples of bioterrorism include the anthrax inhalation from received mail in 2001 (Office of The Surgeon General). Although these are only recorded acts, there is a whole other story to what should happen once a victim is diagnosed with any type of bioterrorism and what treatment they should undergo, if one exists....
