INTRODUCTION
Diabetes mellitus is a deadly disease in many parts of the world. It is a disease condition that is usually characterized with an elevated blood glucose level. Researchers over the years have worked to determine the metabolic pathways of the disease. It is majorly classified as type I (insulin dependent diabetes mellitus) and type II (non-insulin dependent diabetes mellitus). Type II diabetes accounts for approximately 90% of all types of diabetes (Pal et al, 2013). Type 2 diabetes is usually considered as a disease of the old; because it usually occurs in individuals above 40 years of age. However, research has shown an increasing prevalence in the young worldwide. As a result of this, it is important to evaluate the number of young people in Sub-Saharan Africa who are living with type II diabetes. In addition to this, several factors that predispose these individuals to development of type II diabetes early in life. Type II diabetes has numerous significant effects that can affect the quality of life of an individual which could successively affect the economy of a nation.

Melnyk’s Hierarchy of Evidence is a system often use for assigning levels of evidence in nursing by integrates clinical expertise and patient choices with the best available research. It is represented by a pyramid that enumerates the levels of strength of the evidence from 1 to 7, of which level 1 is the higher level. The higher level on the pyramid, the more likelihood that the research is valid; therefore, answering a clinical or practice question. “The systematic review or meta-analysis of randomized controlled trials are at the top of the evidence pyramid and are typically assigned the highest level of evidence, due to the fact that the study design reduces the probability of bias” (Melnyk, 2011). The weakness of the system is that when
This systematic review conducted by Takeda A, Taylor SJC, Taylor RS, Khan F, Krum H, Underwood M, (2012) sourced twenty-five trials, and the overall number of people of the collective trials included was 5,942. Interventions were classified and assessed using the following headings.-
Type 2: Is the most common form of diabetes affecting 90-95% of the 21 million people with diabetes and is more common in African Americans, Latinos, Native Americans, and Asian Americans. Those people who are at higher risk of getting this type of diab...

Diabetes is a disease that affects the body’s ability to produce or respond to insulin, a hormone that allows blood glucose (blood sugar) to enter the cells of the body and be used for energy. Diabetes falls into two main categories: type 1, or juvenile diabetes, which usually occurs during childhood or adolescence, and type 2, or adult-onset diabetes, the most common form of the disease, usually occurring after age 40. Type 1 results from the body’s immune system attacking the insulin-producing cells in the pancreas. The onset of juvenile diabetes is much higher in the winter than in the summer. This association has been repeatedly confirmed in diabetes research. Type 2 is characterized by “insulin resistance,” or an inability of the cells to use insulin, sometimes accompanied by a deficiency in insulin production. There is also sometimes a third type of diabetes considered. It is gestational diabetes, which occurs when the body is not able to properly use insulin during pregnancy. Type 2 diabetes encompasses nine out of 10 diabetic cases. Diabetes is the fifth-deadliest disease in the United States, and it has no cure. The total annual economic cost of diabetes in 2002 was estimated to be $132 billion, or one out of every 10 health care dollars spent in the United States. Diabetes risk factors can fall into three major categories: family history, obesity, and impaired glucose tolerance. Minority groups and elderly are at the greatest risk of developing diabetes.
As diabetes mellitus has 3 different forms, the following report will focus primarily on type 2 diabetes as it is the most prevalent, accounting for 85% of cases (Austalian Institute of Health and Welfare, 2013).
Evidence-based practice is important to consider when researching for interventions, further knowledge, or help to guide a new idea in the health professions. Evidence-based practice is comprised of three significant concepts: respect and awareness for the targeted population’s values, previous clinical practice or experience with that population, and systematic research to establish a better understanding of what is already known about the study’s focus. These concepts are all taken into consideration when designing and conducting a study because it provides a more valid and credible source for others.
Evidence-based practice integrates best current evidence with clinical expertise and patient/family preferences and values for the delivery of optimal health care (qsen.org). Like most medical professions, nursing is a constantly changing field. With new studies being done and as we learn more about different diseases it is crucial for the nurse to continue to learn even after becoming an RN. Using evidence-based practice methods are a great way for nurses and other medical professionals learn new information and to stay up to date on new ways to practice that can be used to better assess

Diabetes Mellitus is a chronic health condition in which the level of glucose in the blood is higher than usual. Type 1 diabetes occurs when the pancreas does not create enough insulin and type 2 diabetes occurs when insulin is produced, but is not adequate in lowering blood glucose levels or there is resistance to the insulin (Edwards, 2007, p. 9). Diabetes mellitus is the leading cause of end-stage kidney disease, foot and leg amputations, and new cases of blindness in the United States (Ignatavicius & Workman, 2010, p. 1465-66). People with type 1 diabetes are required to take insulin to manage their glucose levels. People with type 2 diabetes are usually prescribed oral medications such as sulfonylurea agents, meglitinide analogues, or biguanides to help control their glucose levels. Twenty to 30% of people with type 2 diabetes require insulin therapy as well (Ignatavicius & Workman, 2010, p. 1471). In addition to medication therapy, diet and weight control can help manage both type 1 and type 2 diabetes. Because diabetes mellitus can cause such severe complications, it is important that people with diabetes understand the importance of certain health and lifestyle choices, such as their diet and weight to manage their disease. Patients with diabetes mellitus should pay special attention to the amount of carbohydrates, protein, fat, and minerals that are included in their diet. Monitoring these components of their diet, along with weight management, can help control their diabetes mellitus.
The importance of Evidence-Based Practice is to ensure the best possible care is provided for patients. Evidence-Based Practice functions by measuring the effectiveness of a treatment and differentiating findings between high-quality and low-quality. It also helps with health development and improves the reliability and facilitates students to become reflecti...
