Logistic Regression in Nursing Practice

Logistic regression is used to analyze a wide variety of variables that may surround a singular outcome. For example, logistic regression could be used to identify the likelihood of a patient having a heart attack or stroke based on a variety of factors including age, sex, genetic characteristics, weight, and any preexisting health conditions. The biological systems and issues with which the health care field is concerned represent the kinds of applications for which logistic regression is especially useful.

Logistic regression is used in the health care field for many purposes, including diagnoses, predictions, and forecasting. The three articles in this week’s Learning Resources illustrate the many uses of logistic regression in the health care field. This Discussion allows you to explore the different uses of logistic regression and cultivate a deeper understanding of the application of logistic regression in evidence-based practice.

To prepare:

  • Review      the three articles in this week’s Learning Resources and evaluate their      use of logistic regression. Select one article that interests you to      examine more closely in this Discussion
  • Critically      analyze the article you selected considering the following questions:

 

  1. What       are the goals and purposes of the research study the article describes?
  2. How       is logistic regression used in the study? What are the results of its       use?
  3. What       other quantitative and statistical methods could be used to address the       research issue discussed in the article?
  4. What       are the strengths and weaknesses of the study?
  5. How       could the weaknesses of the study be remedied?
  6. How       could findings from this study contribute to evidence-based practice, the       nursing profession, or society?

By Thursday 10/12/17, 5 pm, write a minimum of 550 words essay in APA format. Use at least 3 references from the list of required reading below.  Include the level one headings as numbered below.

This article outlines the procedures and findings of a study on the use of two methods of neonatal sepsis diagnosis: nearest-neighbor analysis and logistic regression analysis. The results indicated that each method generates unique information useful to diagnosis, and therefore both methods should be used simultaneously for improved accuracy of diagnoses.

     Psychiatric Assessment of the Adult and Older Adult

         Psychiatric Assessment of the Adult and Older Adult

Many assessment principles are the same for children and adults; however, with adults/older adults, consent for participation in the assessment comes from the actual client and not parents or guardians. The exception to this is adults/older adults who have been determined incapacitated by a court of competent jurisdiction. Some adults may be easier to assess than children/adolescents as they are more psychologically minded. That is, they have better insights into themselves and their motivations than children/adolescents (although this is not universally true).

Older adults present some of their own unique assessment challenges in that they may have higher levels of stigma associated with seeking psychiatric care. Additionally, there are higher rates of neurocognitive disorders superimposed on other clinical conditions such as depression or anxiety, which creates additional diagnostic challenges.

This week, you will develop your own personal format for initial interviews of mental health clients. You also will explore the restrictions and limitations for practice as a PMHNP in your home state and create a plan for passing the national certification exam.

Week 1-developing skills in interviewing and diagnostic reasoning

As we begin Week 1, the module is focused on developing an interview format that provides you with questions/responses that you will use in your work-ups and diagnostic assessments or some call them Psychiatric H & P. By now, you have seen many different formats and ways that providers conduct interviews.

For this document, I encourage you to think of your personal style as well as assure that all relevant information is collected in the first interview. Do not use a template that you find online or that your preceptor uses in the office. The purpose of this assignment is for you to think through how you interview patients. There are many examples online to use as a guide. The key elements are similar to a medical H &P, HPI, PPH, PMH, FH, SH, ROS (psychiatric), MSE, Clinical Assessment and Formulation, Diagnosis, and Plan. This will be your ‘bread and butter’, so to speak for your entire career. It is worth spending some time and effort on this. If you put in a canned template, I will not accept your work.
My personal style is what I would call ‘conversational’. I try to engage in some social conversation to get the visit started and then as the patient talks, I make notes on follow-up questions. I keep a list of the basic things that I need for my write-up: HPI, PPH, PMH, Soc/Dev, Substance use, Medication history, Stressors, coping abilities, therapy history. At the end of what I consider ‘the interview’ I review my list to make sure that I have all the information and I sometimes say to patients, “let me make sure that I got all the information that I need to make an accurate diagnosis and develop a treatment plan”. Then, I will say to the patient, “do you have anything that you’d like to add?”

This conversational style is not for everyone and I know many providers that use more of a ‘checklist’ style. Think about what you want and how you will feel most comfortable. Feel free to provide feedback to your colleagues –there are no right or wrong styles.

Instructions- Week 1:

Despite what you may believe (or may have been told), there is no such thing as one “right” way to do an interview. In fact, there are numerous books written about the various ways of conducting the clinical interview. In actual clinical practice, you will find the format that “works” best for you and addresses your unique strengths and the needs of the client.

In this Discussion, you will practice finding the interview format that works for you and share those ideas with your colleagues for feedback.

Learning Objectives

Students will:

  • Develop formats for initial interviews of mental health clients

To prepare for this Discussion:

  • Review  the Learning Resources.
  • Develop an interview format you would use for an initial interview of a client.

                                                           ASSIGNMENT

  • Attach  the interview format document you would use for an initial interview of a client.
  • Describe      what interview format your preceptor uses for the initial interview of a  client.
  • Describe      which element of your interview format is most helpful in your practice.

Question 1: Art of the Americas

This week, we studied a vast array of cultural objects produced in North, South, and Central America prior to 1492. Select one object from each of the following cultures: Aztec, Inca, and North (Native) American.

First, identify each object, including its name, date, medium, and location/geographical region of origin.

Then, in a minimum of 2 well-developed paragraphs, address the following questions for each object:

  1. What are the unique and specific visual characteristics of the object? How are these visual characteristics typical of the time and place in which the object was created?
  2. How does meaning or function of the object reflect the culture in which it was produced?

Question 2: Neoclassicism, Romanticism, and Realism

Beginning in the 19th century, artistic movements carry the suffix “-ism” to their name. Originally derived from Ancient Greek, “-isms” is appended to a word that then reflects a philosophical concept. In the case of art, it comes to mean the philosophy or approach to art that binds a group of artists together.

Select one representative example from each of the following “-isms” studied this week: Neoclassicism, Romanticism, and Realism. In 3 well-developed paragraphs, discuss:

  1. What is the philosophy or approach to art that is defined by the –ism.
  2. What are the specific visual characteristics of your example that are representative of the overall style of the –ism?
  3. How does the specific subject of your selected work reflect the philosophy of the –ism?

Be sure to explain your ideas clearly and support them by discussing specific works of art that you have read about this week, talking about how they illustrate and support your ideas.
