THE DATA KNOWLEDGE

Using the Data/Information/Knowledge/Wisdom Continuum

Assignment: Application:
Using the Data/Information/Knowledge/Wisdom Continuum

Have you ever gone online to search for a journal article on a specific topic? It is amazing to see the large number of journals that are available in the health care field. When you view the library in its entirety, you are viewing untapped data. Until you actually research for your particular topic, there is little structure. Once you have narrowed it down, you have information and once you apply the information, you have knowledge. Eventually, after thoughtful research and diligent practice, you reach the level of wisdom—knowledge applied in meaningful ways.

Are there areas in your practice that you believe should be more fully explored? The central aims of nursing informatics are to manage and communicate data, information, knowledge, and wisdom. This continuum represents the overarching structure of nursing informatics. In this Assignment, you develop a research question relevant to your practice area and relate how you would work through the progression from data to information, knowledge, and wisdom.

To prepare:

  • Review the information in Figure 6–2 in Nursing Informatics and the Foundation of Knowledge.
  • Develop a clinical question related to your area of practice that you would like to explore.
  • Consider what you currently know about this topic. What additional information would you need to answer the question?
  • Using the continuum of data, information, knowledge, and wisdom, determine how you would go about researching your question.
    • Explore the available databases in the Walden Library. Identify which of these databases you would use to find the information or data you need.
    • Once you have identified useful databases, how would you go about finding the most relevant articles and information?
    • Consider how you would extract the relevant information from the articles.
    • How would you take the information and organize it in a way that was useful? How could you take the step from simply having useful knowledge to gaining wisdom?
By Day 7 of Week 4

Write a 4-page paper that addresses the following: MUST BE APA FORMAT

  • Summarize the question you developed, and then relate how you would work through the four steps of the data, information, knowledge, wisdom continuum. Be specific.
    • Identify the databases and search words you would use.
    • Relate how you would take the information gleaned and turn it into useable knowledge.
  • Can informatics be used to gain wisdom? Describe how you would progress from simply having useful knowledge to the wisdom to make decisions about the information you have found during your database search.

Your paper must also include a title page, an introduction, a summary, and a reference page ( YOU CAN ONLY USE THE REFERENCES LISTED BELOW).

Family Focused Assessment

Develop an interview questionnaire to be used in a family-focused functional assessment. The questionnaire must include three open-ended, family-focused questions to assess functional health patterns for each of the following:

  1. Values/Health Perception
  2. Nutrition
  3. Sleep/Rest
  4. Elimination
  5. Activity/Exercise
  6. Cognitive
  7. Sensory-Perception
  8. Self-Perception
  9. Role Relationship
  10. Sexuality
  11. Coping

Select a family, other than your own, and seek permission from the family to conduct an interview. Utilize the interview questions complied in your interview questionnaire to conduct a family-focused functional assessment. Document the responses as you conduct the interview.

Upon completion of the interview, write a 1000- 1250 word paper. Analyze your assessment findings. Submit your questionnaire as an appendix with your assignment.

Include the following in your paper:

Describe the family structure. Include individuals and any relevant attributes defining the family composition, race/ethnicity, social class, spirituality, and environment.

Summarize the overall health behaviors of the family. Describe the current health of the family.

Based on your findings, describe at least two of the functional health pattern strengths noted in the findings. Discuss three areas in which health problems or barriers to health were identified.

Describe how family systems theory can be applied to solicit changes in family members that, in turn, initiate positive changes to the overall family functions over time.

Cite at least three peer-reviewed or scholarly sources to complete this assignment. Sources should be published within the last 5 years and appropriate for the assignment criteria.

The Systems Development Life Cycle and the Nurse Informaticist

The systems development life cycle (SDLC) is a model for planning and implementing change within an organization. It is important for many individuals to be represented in the process, especially the end users of the system or the employees who must live with the change. As informatics become more and more widespread throughout the health care field, collaboration between information technology (IT) professionals and health care practitioners is becoming increasingly important. The nurse informaticist is able to combine the perspective of the information technology side with the clinical nursing perspective.

While the titles and specific responsibilities of nurse informaticists vary across organizations and practice settings, the fundamental purpose of the role remains the same. Nurse informaticists synthesize their knowledge of how technology can improve health care with an understanding of clinical practice and workflow. This is why nurse informaticists can be instrumental in facilitating the SDLC for informatics in health care. For this Discussion, you examine the relationship between the nurse informaticist and the use of the SDLC.

To prepare:

  • Review the information in this week’s Learning Resources on the SDLC and the role of the nurse informaticist. Reflect on Chapter 1 of the Dennis, Wixom, and Roth course text and consider how the information about the systems analyst role translates into nursing and health care.
  • Consider a recent change in your organization related to the implementation of a new technology or system. How was this change handled? What was the general SDLC process? Who was involved, and what were the outcomes?
  • Identify whether your organization (or one with which you are familiar) has a formal title or position for the nurse informaticist. This position may be called by a different name, such as nurse informatics specialist or informatics analyst, so be sure to review the position description.
  • If your organization has a position for the nurse informaticist, what are the responsibilities of that position? If your organization does not have such a position, conduct research in the Walden Library and at credible online sources on the role of the nurse informaticist.
  • Reflect on the role of the nurse informaticist in the overall health care field. How is this position connected to the SDLC? Assess the benefits of having this specialized position within health care organizations and involving the nurse informaticist in the SDLC.  Post by tomorrow 8/30/16 550 words in APA format with a minimum of 3 references from the list provided under Required Readings. Apply the level 1 headings as numbered below:1) A description of how the systems development life cycle is utilized in your organization (Hospital), or in one with which you are familiar, and assess its effectiveness. 2)  Assess the role of the nurse informaticist in your organization. If the nurse informaticist is not a current position within your organization, provide a description of the generally accepted role of the nurse informaticist based on this week’s Learning Resources and your own research. 3)  Explain why it is important for the nurse informaticist to be involved in the SDLC process and the overall organizational benefits of having such involvement.

Work Breakdown Structure (WBS)

Within reason, is there such a thing as a project that is too complex to complete? Consider the Space Shuttle. One of the most complex machines ever built, the Space Shuttle had over 2.5 million parts, each of which had to be accounted for by someone. How did anyone manage to track and properly assemble these parts? The answer is through the application of a work breakdown structure (WBS). A WBS is a fundamental tool that project managers use to organize and divide the work of a project. A WBS focuses on breaking down a project’s scope into individual deliverables that may be created by assigned team members.

There are multiple work breakdown structure formats and each has its own advantages and disadvantages. Project managers select a type of WBS based upon the specifics of the project they are managing. Each WBS format emphasizes different aspects of a project. These varied perspectives may each be appropriate, depending upon what information a project manager needs.

In this Discussion, you analyze different WBS formats and evaluate whether they meet basic criteria for clarity.

To prepare:

  • Explore the Work Breakdown Structure Formats document included in this week’s Learning Resources. The document presents a scenario and three corresponding WBS formats that pertain to the scenario. (SEE ATTACHED PDF FILE)
  • Consider the advantages and disadvantages of each WBS format included in the document.
  • Think about the level of detail dedicated to task information in each WBS format. Evaluate the formats based on the following criteria for clarity:
  • The task has a measurable status or completion.
  • The task has defined start and end events.
  • The task has a deliverable.
  • The task’s time and cost are easily estimated.
  • The task can be completed without interruption and additional input after its start.

Post  by tomorrow 10/04/16 a minimum of 550 words essay in APA format with 3 references. Based on the Work Breakdown Structure Formats document attached in the file area, address the level one headings as numbered below:

1) An analysis of the advantages and disadvantages of each work breakdown structure format.

2) Provide an analysis of whether (and how) the work breakdown structures meet the assigned criteria for clarity.

3) Provide a rationale for your response.

Understanding Independent Samples t-Test

Statistical Technique in Review

The independent samples t-test is a parametric statistical technique used to determine significant differences between the scores obtained from two samples or groups. Since the t-test is considered fairly easy to calculate, researchers often use it in determining differences between two groups. The t-test examines the differences between the means of the two groups in a study and adjusts that difference for the variability (computed by the standard error) among the data. When interpreting the results of t-tests, the larger the calculated t ratio, in absolute value, the greater the difference between the two groups. The significance of a t ratio can be determined by comparison with the critical values in a statistical table for the t distribution using the degrees of freedom (df) for the study (see Appendix A Critical Values for Student’s t Distribution at the back of this text). The formula for df for an independent t-test is as follows:

df=(numberofsubjectsinsample1+numberofsubjectsinsample2)−2 

Exampledf=(65insample1+67insample2)−2=132−2=130 

The t-test should be conducted only once to examine differences between two groups in a study, because conducting multiple t-tests on study data can result in an inflated Type 1 error rate. A Type I error occurs when the researcher rejects the null hypothesis when it is in actuality true. Researchers need to consider other statistical analysis options for their study data rather than conducting multiple t-tests. However, if multiple t-tests are conducted, researchers can perform a Bonferroni procedure or more conservative post hoc tests like Tukey’s honestly significant difference (HSD), Student-Newman-Keuls, or Scheffé test to reduce the risk of a Type I error. Only the Bonferroni procedure is covered in this text; details about the other, more stringent post hoc tests can be found in Plichta and Kelvin (2013) and Zar (2010).

The Bonferroni procedure is a simple calculation in which the alpha is divided by the number of t-tests conducted on different aspects of the study data. The resulting number is used as the alpha or level of significance for each of the t-tests conducted. The Bonferroni procedure formula is as follows: alpha (α) ÷ number of t-tests performed on study data = more stringent study α to determine the significance of study results. For example, if a study’s α was set at 0.05 and the researcher planned on conducting five t-tests on the study data, the α would be divided by the five t-tests (0.05 ÷ 5 = 0.01), with a resulting α of 0.01 to be used to determine significant differences in the study.

The t-test for independent samples or groups includes the following assumptions:

1. The raw scores in the population are normally distributed.

2. The dependent variable(s) is(are) measured at the interval or ratio levels.162

3. The two groups examined for differences have equal variance, which is best achieved by a random sample and random assignment to groups.

4. All scores or observations collected within each group are independent or not related to other study scores or observations.

The t-test is robust, meaning the results are reliable even if one of the assumptions has been violated. However, the t-test is not robust regarding between-samples or within-samples independence assumptions or with respect to extreme violation of the assumption of normality. Groups do not need to be of equal sizes but rather of equal variance. Groups are independent if the two sets of data were not taken from the same subjects and if the scores are not related (Grove, Burns, & Gray, 2013; Plichta & Kelvin, 2013). This exercise focuses on interpreting and critically appraising the t-tests results presented in research reports. Exercise 31 provides a step-by-step process for calculating the independent samples t-test.

Canbulat, N., Ayhan, F., & Inal, S. (2015). Effectiveness of external cold and vibration for procedural pain relief during peripheral intravenous cannulation in pediatric patients. Pain Management Nursing, 16(1), 33–39.

Introduction

Canbulat and colleagues (2015, p. 33) conducted an experimental study to determine the “effects of external cold and vibration stimulation via Buzzy on the pain and anxiety levels of children during peripheral intravenous (IV) cannulation.” Buzzy is an 8 × 5 × 2.5 cm battery-operated device for delivering external cold and vibration, which resembles a bee in shape and coloring and has a smiling face. A total of 176 children between the ages of 7 and 12 years who had never had an IV insertion before were recruited and randomly assigned into the equally sized intervention and control groups. During IV insertion, “the control group received no treatment. The intervention group received external cold and vibration stimulation via Buzzy . . . Buzzy was administered about 5 cm above the application area just before the procedure, and the vibration continued until the end of the procedure” (Canbulat et al., 2015, p. 36). Canbulat et al. (2015, pp. 37–38) concluded that “the application of external cold and vibration stimulation were effective in relieving pain and anxiety in children during peripheral IV” insertion and were “quick-acting and effective nonpharmacological measures for pain reduction.” The researchers concluded that the Buzzy intervention is inexpensive and can be easily implemented in clinical practice with a pediatric population.

Relevant Study Results

The level of significance for this study was set at α = 0.05. “There were no differences between the two groups in terms of age, sex [gender], BMI, and preprocedural anxiety according to the self, the parents’, and the observer’s reports (p > 0.05) (Table 1). When the pain and anxiety levels were compared with an independent samples t test, . . . the children in the external cold and vibration stimulation [intervention] group had significantly lower pain levels than the control group according to their self-reports (both WBFC [Wong Baker Faces Scale] and VAS [visual analog scale] scores; p < 0.001) (Table 2). The external cold and vibration stimulation group had significantly lower fear and anxiety 163levels than the control group, according to parents’ and the observer’s reports (p < 0.001) (Table 3)” (Canbulat et al., 2015, p. 36).

Study Questions

1. What type of statistical test was conducted by Canbulat et al. (2015) to examine group differences in the dependent variables of procedural pain and anxiety levels in this study? What two groups were analyzed for differences?

2. What did Canbulat et al. (2015) set the level of significance, or alpha (α), at for this study?

3. What are the t and p (probability) values for procedural self-reported pain measured with a visual analog scale (VAS)? What do these results mean?

4. What is the null hypothesis for observer-reported procedural anxiety for the two groups? Was this null hypothesis accepted or rejected in this study? Provide a rationale for your answer.

5. What is the t-test result for BMI? Is this result statistically significant? Provide a rationale for your answer. What does this result mean for the study?165

6. What causes an increased risk for Type I errors when t-tests are conducted in a study? How might researchers reduce the increased risk for a Type I error in a study?

7. Assuming that the t-tests presented in Table 2 and Table 3 are all the t-tests performed by Canbulat et al. (2015) to analyze the dependent variables’ data, calculate a Bonferroni procedure for this study.

8. Would the t-test for observer-reported procedural anxiety be significant based on the more stringent α calculated using the Bonferroni procedure in question 7? Provide a rationale for your answer.

9. The results in Table 1 indicate that the Buzzy intervention group and the control group were not significantly different for gender, age, body mass index (BMI), or preprocedural anxiety (as measured by self-report, parent report, or observer report). What do these results indicate about the equivalence of the intervention and control groups at the beginning of the study? Why are these results important?

10. Canbulat et al. (2015) conducted the χ2 test to analyze the difference in sex or gender between the Buzzy intervention group and the control group. Would an independent samples t-test be appropriate to analyze the gender data in this study (review algorithm in Exercise 12)? Provide a rationale for your answer.166
