    Which epidemiological study design would you use to evaluate an intervention in your practice? Provide a description of the chosen population and the identified intervention. Provide support as to why you believe that the design you chose is the best option including the strengths and weaknesses of the design you have chosen.

    Week 2 Paper due 1/14/19

    The Epidemiology Paper is a practice immersion assignment designed to be completed in three sections, this is part one of the assignment. Learners are required discuss the role of descriptive epidemiology in nursing science and apply descriptive epidemiology in nursing science.

    General Guidelines:

    Use the following information to ensure successful completion of the assignment:

    • This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion.
    • Doctoral learners are required to use APA style for their writing assignments. The APA Style Guide is located in the Student Success Center.
    • This assignment requires that support your position by referencing at least six to eight scholarly resources. At least three of your supporting references must be from scholarly sources other than the assigned readings.
    • You are required to submit this assignment to LopesWrite. Please refer to the directions in the Student Success Center.


    Write a 1,250–1,500 word paper discussing the role of descriptive epidemiology in nursing science. Include the following:

    1. Define descriptive epidemiology and describe its relationship and role in nursing science today.
    2. Provide a contemporary example of how descriptive epidemiology is applied in public health nursing.
    3. Identify the epidemiology components used to analyze at-risk populations.

    Portfolio Practice Hours:

    Practice immersion assignments are based on your current course objectives, and are intended to be application-based learning using your real-world practice setting. These assignments earn practice immersion hours, and are indicated in the assignment by a Portfolio Practice Hours statement that reminds you, the learner, to enter a corresponding case log in Typhon. Actual clock hours are entered, but the average hours associated with each practice immersion assignment is 10.

    You are required to complete your assignment using real-world application. Real-world application requires the use of evidence-based data, contemporary theories, and concepts presented in the course. The culmination of your assignment must present a viable application in a current practice setting. For more information on parameters for practice immersion hours, please refer to DNP resources in the DC Network.

DNP-825 Week 2 DQ 2: Evaluation of Intervention Using an Epidemiological Study Design

            Randomized clinical trial is a selected design for testing the efficacy and safety of a new experimental drug. A randomized clinical trial is well thought-out as the gold standard study design. In this approach, the investigator will randomly assign subjects to an experimental group and a control group. The experimental group will receive treatment/intervention; whereas, the control group does not receive treatment/intervention but a placebo treatment. Alternately, the control group can be administered with the standard treatment rather than the experimental agent (Munnangi & Boktor, 2018).

            This design is characterized by certain strengths and weaknesses. One of the key strength is that randomization minimizes selection bias and avoids confounding. Confounding refers to confusing the effect of two or more variables for example the effect the experimental drug and standard treatment (Munnangi & Boktor, 2018). In other words, the randomized control trial is the most robust and rigorous study method of evaluating whether a cause and effect relationship exist between a given intervention and outcome. It can give high-quality evidence for evaluating the safety and effectiveness of an intervention (Bhide, Shah, & Acharya, 2018). It enables the investigator to have similar control groups and experimental groups, which will allow for allow for isolation of the intervention. On the other hand, this study design is expensive. In addition, investigators who use this this design may face issues such as drops outs, refusals, non-compliance, and crossovers (Munnangi & Boktor, 2018). Another weakness is time and resources necessary for planning since this design require rigorous and careful coordination and planning (Bondemark & Ruf, 2015). Despite the above weaknesses, this standard can help provide high-quality evidence of the safety and efficacy of the new experimental drug.
