  1. Describe three concepts addressed in this course that you believe will have the greatest impact on your practice after you have earned the Doctor of Nursing practice (DNP) degree. The concepts can be narrow, for example, the role of the null hypothesis in determining statistical significance. Or the concepts can be broad, for example, the importance of interpreting the clinical significance of findings when considering whether an intervention has a strong potential for making a positive change in the quality of care given to your patients in your setting.
  2. Envision implementing practice projects in your setting. Have any practice projects been implemented in your setting or agency? If not, find an article that described in some detail the implementation of a practice change project. To what extent were research results used as the basis for the change? Describe the process and whether the project had a long-term positive effect. What are the facilitators in your setting that will help you implement this important aspect of the nurse with an advanced degree? What are the barriers in your setting to implementing this role?

Purpose: 

This assignment gives the student the opportunity to develop an abbreviated DNP project proposal with a priority focus on developing a plan for statistical analysis that includes methods for gathering and recording data. 

Process: 

Choose a topic you are interested in as a possible topic for the project you will conduct toward the end of the program. You may, and probably will, change your mind about a focus for the DNP project many times as the program goes on. The purpose of this project is not for you to create a first draft of the project you will conduct. The purpose is for you to demonstrate how to formulate a data analysis plan that will fulfill the purpose of a practice change project.  

Objectives: 

  1. Summarize previous research that justifies the importance of and an intervention related to a nursing practice issue.
  2. Create and analyze the components of a correctly worded project purpose statement and project question for a hypothetical nursing practice change project.
  3. Develop the methods section with emphasis on the details of a data analysis plan for a hypothetical nursing practice change project.
  4. Discuss the results of a hypothetical nursing practice change project.
  5. utilize professional and correct use of APA format and style.

Module 2: Topic, PICO Question, & Article

/in /by

 

Choose a topic from the topic list on the attached instructions.

Write a PICO question that relates to your topic.

Find a quantitative nursing research article. Make sure that it is actually nursing research. You may not use any of the following:

  • A retrospective study (exceptions as noted on worksheet)
  • A mixed methods study
  • A qualitative research article
  • A systematic review
  • A quality improvement article
  • An evidence based practice article

You may not use the article that is being used for the RACs in this course session.

If you are repeating the class, you may not use the article or topic that you used for your last attempt at this class.

You may receive help from librarians in finding an article, but you are ultimately responsible for whether it meets requirements or not.

Upload the worksheet and your article. The article must be in pdf format.

Topics

Addiction

Adherence

Alarm safety

Comfort

Delirium

Depression

Diabetes management

Discharge teaching

Falls

Functional ability

Health and wellbeing of nurses

Hospital readmission rates

Infection control

Mobility

Pain

Prenatal teaching

Prevention of post operative complications

Prevention of pressure ulcers

Sleep disturbances

Stress

Now, we will construct your question.

First, make sure that your question is a practice question, not a research question.

A practice question is a question that answers a problem you have as a practicing nurse. A research question focuses more on basic knowledge. Sometimes there is some overlap, and there are questions that could be either practice questions or research question.

First, identify each element of your PICO on the line below, then take a look at the templates below to help you formulate a PICO(T) question.

P: Population/disease ( i.e. age, gender, ethnicity, with a certain disorder)

P: _______________________________________________________________

I: Intervention or Variable of Interest (exposure to a disease, risk behavior, prognostic factor) Note: Not every question will have an intervention (as in a meaning question – see below).

I: _______________________________________________________________

C: Comparison: (could be a placebo or “business as usual” as in no disease, absence of risk factor). Note: This is not used in a meaning question – see below.

C: ______________________________________________________________

O: Outcome: (risk of disease, accuracy of a diagnosis, rate of occurrence of adverse outcome)

O: _______________________________________________________________

T: Time: The time it takes to demonstrate an outcome (e.g. the time it takes for the intervention to achieve an outcome or how long participants are observed). This is an optional “add-on” for a PICO question.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

For PICO questions about a nursing intervention/therapy:

In _______(P), what is the effect of _______(I) on ______(O) compared with _______(C) within ________ (T)?

For PICO etiology questions:

Are ____ (P) who have _______ (I) at ___ (increased/decreased) risk for/of_______ (O) compared with ______ (P) with/without ______ (C) over _____ (T)?

For PICO questions involving prevention:

For ________ (P) does the use of ______ (I) reduce the future risk of ________ (O) compared with _________ (C)?

For PICO questions that predict:

Does __________ (I) influence ________ (O) in patients who have _______ (P) over ______ (T)?

When you have decided on the final form of your topic and your PICO(T) question, fill out the worksheet and upload it in Canvas. Be sure to upload your quantitative nursing research article as well.

Using one of the experimental studies that tested an intervention that you used previously in the course or a different study, complete these tasks and answer these questions:

  • Provide the purpose/objective/aim of the study in the exact words used in the study.
  • From the purpose/objective/aim of the study, identify:
    • The population
    • The intervention (independent variable)
    • The outcome (dependent) variable
      • What is the level of measurement of the DV (nominal, ordinal, interval, or ratio)? Provide the rationale based on the instrument used to measure the DV. What type of variable is the DV (categorical or continuous)?
  • Write the null and alternative hypotheses in words and equation format for one of the inferential tests related to the purpose of the study.
  • Give the values for the descriptive statistics for the outcome variable.
  • What inferential test was used to test the effectiveness of the intervention? Give the rationale for this test based on the level of measurement of and the descriptive statistic reported for the outcome variable.
  • What are the assumptions for this test (cite the source where you find them)? Are they met in this study? Provide information given in the study that can be used to determine whether each assumption is or is not met. What information is not given?
  • Using the p-value rule, was the intervention effective based on statistical analysis? State the rule and the decision about the null hypothesis.
  • Based on the decision related to the null hypothesis, what type of statistical error is possible? What are possible causes of this error? What did the researcher do to minimize the possible error?
  • Identify at least two of the common statistical errors listed in Chapter 15 in the textbook to explain what the researcher could have done to avoid these mistakes and ensure the validity of the findings.
  •  Using the Balkin & Lenz (2021), Barria (2023) or Ranganathan et al. (2016) article plus your clinical knowledge of the intervention and outcome variables, critical thinking, and your experience with your patients and setting, do the results of this study have clinical significance? Is the difference in the value of the descriptive statistic large enough to predict that the benefit of adopting the intervention would justify the cost (not just money) and effort of implementing the intervention? Does the clinical significance of the results of this study match the statistical significance? Explain your answer.

 This upcoming task will ideally, but not necessarily, be focused on a topic you are interested in as a possible topic for the project you will conduct. The purpose of this project is not for you to draft parts of the project you will conduct. The purpose is for you to demonstrate how to formulate a data analysis plan that will fulfill the purpose of a practice change project. Here is the outline of part of the content of a proposal for a hypothetical DNP project with a focus on statistical analysis. DNP projects are a type of translational research – translating previous research into practice. For this task, you should use a previously published project or research study as the basis for the methodology of a hypothetical project. When this is done in an actual project, the previous research methodology is adopted to the specific setting, patients, and time frame for the project. Cite the research study that you are using as a basis for your proposal Use this outline to organize your contribution this week. 

  • State the purpose of the project. Cite the research that is the basis for the proposal.
  • Transform the purpose statement into a PICOT-formatted project question (See the Gallagher & Melnyk, 2019, editorial for additional information cited under the Instructional Resources for this week.).
    • P = Population – who will be included in the project and how many groups will be studied in the project.
    • I = Intervention – the treatment or intervention that will be manipulated or changed during the implementation phase of the project.
    • C = Comparison – the usual treatment or intervention used prior to the project.
    • O = Outcome – the characteristic that will be measured to determine the effect of the intervention.
      • Find or identify a data collection instrument to measure this variable and give the name of the instrument.
      • Indicate what type of variable this instrument collects (categorical or continuous) and what level of measurement it is (nominal, ordinal, interval, variable).
    • T = Time: Total time for data collection from the start of data collection to the end. 
  • Data analysis – Descriptive statistics:
    • Identify the descriptive statistics that will be used to organize and summarize the data collected that will fulfill the purpose of the study – choose one of the descriptive statistics listed below and give the rationale for your choice based on the type of data produced by the data collection instrument:
      • Measure of central tendency with measure of variability and range.
      • Frequency with percentages.
  • Describe the most effective method to use for illustrating the descriptive statistics with a graph or histogram.
  • Data analysis – inferential statistic:
    • Name the most appropriate inferential statistic to use to fulfill the purpose of the study:
    • Give the rationale for your choice based on the purpose statement, PICO-formatted project question, and the type of data produced by the data collection instrument.
    • What are the assumptions for this test?
  • Write the null and alternative hypotheses for the inferential statistic in words and in an equation using the same designations of the population, variables, and time that were used in the purpose statement and PICOT-formatted project question.
  • How will the effect size of the findings be determined? Give the rationale for your choice based on the inferential test used.

Find a published research study on a topic that you could use for your DNP project that reported ORs or RRs(NO meta-analysis)

  • Give the purpose/objective/aim of the study exactly as it is written in the study.
    • What is the population in the study?
    • Identify the variables in the study that you will focus on. Designate the variables as an IV and DV. What is the level of measurement of the variables (nominal, ordinal, interval, or ratio), and type (categorical or continuous)?
  • If one or more hypotheses were stated in the article for the OR or RR, give the one you will focus on here. Give the stated hypothesis as an equation. Write the other hypothesis (the Ho or Ha that was not given) in words and an equation. If a hypothesis was not stated, then restate the purpose/objective/aim as a null hypothesis in words and equation format. Do this for both a null and alternative hypothesis. Again, focus on only two sets of variables tested by an OR or RR. Use the format in the handout attached to the announcement for this week.
  • What is the assumption for ORs or RRs (cite the source where you find it)? Is it met in this study? Provide information given in the study that can be used to determine whether each assumption is or is not met. What information is not given?
  • What alpha level (level of significance) was used?
  • Give the descriptive statistics for at least two risk factors and related outcome(s) analyzed by ORs or RRs.
  • Give the values for the ORs or RRs and p-value for the risk factors named used for the descriptive statistics.
  • Use the p-value rule to determine whether to reject or fail to reject the null hypothesis.
  • What type of error is possible based on the decision about the null hypothesis? List the common reason(s) for this possible error and identify which of them applies to this study.
  • If CIs are reported for the ORs or RRs, use the CI rule to determine whether to reject or fail to reject the null hypothesis.
  • Do the risk factors increase or decrease the risk of the outcome or event? Explain your answer.
  • Convert the OR or RR to a percentage and interpret the magnitude of the OR or RR.
  • Determine the clinical significance of the ORs or RRs by using your knowledge, critical thinking, and experience with your patients and setting, would you incorporate the variables into your practice, for example, adding them to your assessment in order to identify patients at risk for the outcome or event? Is your evaluation of the clinical significance of the findings consistent with the statistical significance for the findings? Explain your rationale.
