Evidence-Based Practice and Research in Nursing
Mattress overlay is specially designed to distribute weight of the body across the bed. This relieves the pressure from shoulders and hips. It also increases the contoured surface area through air circulation whereas foam fingers massage during the rest. Chemicals in the material should be safe and non-allergic to human skin. Density of these overlays should be between 4-5 pounds. Hospital uses mattress overlays that improve circulation and helps to prevent pressure ulcers. They are filled with substances like water, gel air, foam or combinations. According to this research, a new mattress overlay reduces the incidence of skin breakdown by 25%. Following are the aspects of the research that should be examined carefully: 1. Type of mattress: We should check if they are made of foam or any liquid-filled. 2. Type of material used: Chemicals, fibers or plastics are commonly used for the gel-based overlay and it should be properly analyzed. 3. Comparison with overlay: Such comparison will help us to find the best available option. 4. Density of the mattress is also very important criterion. 5. Correction of experimental procedures and results should also be critically analyzed.
Evidence-based practice includes the nurses taking information from previous cases and research to understand present cases. They use their previous knowledge to determine the right intervention to be applied. Nurses are also engaged in researches, and also publish papers. Evidence-based practice originates when a nurse combines her medical expertise and previous cases to deliver the best help to the patient. The clinical practice involves a lot of evidence-based research. Clinical experts also integrate evidence-based research and practice to deliver best outcomes. Client values and preferences fall under previous practice, which is a part of evidence-based practice. Hence, the options 1, 2 and 3 are incorrect. Trial and error do not fall under the evidence-based practice category. A trial and error method is purely based on gut feeling, guess, and a little experience. It cannot be counted as something reasonable that may have happened in the past, and cannot be used as a previous medical history. Hence, the correct answer is option .
Evolutionary-based practice (EBP) is an evidence-based practice involves clinical decision-making using various evidences for use in specific settings and for clients. Research is used through two approaches such as quantitative and qualitative approaches. Quantitative approach includes statistics and mathematics. Qualitative approach includes descriptive narration based on evidences and rational thinking. Being well informed is a desired quality of a nurse in an EBP environment. In this case, a nurse should critically review the findings. Nurse should also cross check other reports related to the topic. Type of material, physical requirements and specifications should also be known apart from data related to the effects on the patients. Thus, the model of EBP that can be used to study such report is mentioned below: 1. Ask for the clinical questions. 2. Search for the proof and evidence. 3. Critically follow the evidence. 4. Integrate the evidence with other factors. 5. Examine the outcome of interventions.
