NURSING 439 CHAMBERLAIN COLLEGE OF NURSING - DISCUSSION WEEK 3 Week 3: Research Problems, Designs, and Sample This week, we will discuss the research design and sample for your nursing clinical iss... ue. The research design flows from the research question and outlines the plan for the study that will answer the research question. The design identifies the major components of the study. It is important to remember that there is no one best design for a research study. 1. After you review the designs, describe which research design you would expect to find when searching for evidence relevant to your own research question from Week 2. Why? Explain your answer. 2. The most common sampling method is the convenience sample; therefore, many of the studies that you find for evidence use this sampling method. What are the implications for using a convenience sample on the way you interpret and use the findings? "A research design is an outline of the study, in both a macro sense and a micro sense" (Houser, 2018, pg. 133). The bases of a design are the demands of the research questions, along with a sampling plan and the measurements. Research design is the way to make sure you integrate all components of the study in a logical way making sure that the research problem is successfully reached. "Some design flaws may have little impact on the studies outcome; others may fatally affect the credibility of the results" (Houser, 2018, pg. 135). Week Two PICOT Question: Adults in the Emergency Department that present with pain, how would RN initiated STAT analgesic orders protocol compare to waiting for physician analgesic orders, help reduce patient pain and improve patient satisfaction scores in the Emergency Department? "A clear definition of the concepts that will be studied guides the design of the study and the subsequent measurement strategy" (Houser, 2018, pg.137). When looking at my PICOT Questions from week two, I believe a comparative effectiveness design such as Observational would work best. This design is described as a "Population of interest assigned to alternative interventions based on the patient, provider, and system factors and observed for the outcome of interest" (Houser, 2018, pg. 147). When looking at the question, we are observing patients in the Emergency Departments when they receive RN initiated analgesics compared to waiting for physician's assessments and orders. When are observing the patient outcome by seeing if their pain is relieved sooner and if the Emergency Departments satisfactory scores increase. This design would prove to be very effective for this study, but is subject to selection bias and measurement errors. As we learned in this week's lesson, convenience sampling is the most common sampling method used in studies. By convenience sampling it means that the sample used for the research is easily accessible to the researchers. Though this form of sampling as many advantages, it has potential for selection bias. This form of sampling is not only used because it is convenient, but it also allows the researcher to collect data without dealing with a randomized sample. Chamberlain University. (2017).
