Evidence Based Practice Case Study

Introduction This case study based on an elderly man named David is 56years old and has a number of personal health issues that are affecting his daily life and on top on that his wife has a history of breast cancer. The evidence-based practice is a clinical activity which is based on the belief that decision about the delivery of care to clients should be informed by the best available and current scientific evidence (Beanland et al 2011). So as a nurse it is important to understand why evidence based practice is essential when caring for a patient and to be able to apply the best possible evidence to each individual situation.
Another definition of evidence based practice is that it is a process within which clinical decision
People are likely to be affected by obesity and weight gain Due to the consumption of excess amounts of cholesterol, saturated fat and Tran’s fat in the diet. Fat and obesity are usually measured by the body mass index (BMI) formula and waist circumference. Heart disease and other health problems are generally caused by excess fat, usually around the waist. This case study focuses on “ obesity as a contributing factor to heart diseases” which will be discuss and criticise by the analysis of various authors and their research about the subject by applying the following process such as synthesising research evidence . Then designing clinical practice guiding which would implement the practice changes and evaluate the outcomes (Sackett, Strans, Richardson, Rosenberg & Haynes, 2009). Researchers demonstrated ( Newman, Ann Mabe, 2009) the main problem with obesity is that it can lead to risk factors which put people at a higher risk of developing heart diseases such as high blood pressure and type 2 diabetes. The evidence shows, that (Hamer M, Stamatakis E. 2012) that the diabetes mellitus, hypertension, metabolic syndrome, heart disease, are most result from genetic factor which contributes to obesity in an older adult. Evidence shows, that (Krentz, Andrew J.; Wong, Nathan D, 2007) the most important cause of metabolic syndrome is obesity which being recognized and associated with other
This also increases the emphasis on performance and outcome standards. An answerable question “Is obesity a contributing factor to heart diseases?”

Locating the evidence A review of literature, was done by using Cinahl, medline and Cochrane databases. A Combination of Keywords used for research were obesity and heart attack and above age group 56, which refined the research by resulting 15,084 hits. Limitation required to be set to reduce the numbers of articles to be refined. Selection criteria used to limit the search down by filtering the search by peer reviewed, English language, and data range between years 2008-2015. Numbers of articles hits after selection criteria was 943 still allot to be reviewed.
