HLT 540 Health Care Research Methods, Analysis, and Utilization

 

HLT 540 Full Course

 

GC HLT540 week 1 dq 1 & dq 2

 

dq 1

 

Why do you think many healthcare practitioners are often unwilling to change practice patterns, based on research findings? Some practitioners criticize evidence-based practice as “cookbook care.” Considering these perceptions, how would you utilize your education and experiences in planning the implementation of a major change?

 

dq 2

 

Consider the question: “Why do physicians and nurses kill more people than airline pilots?” Apply your critical thinking skills to this argument and critique the statement. First, do you think it’s true? If it is, what do you think about their rationale? How would you address it if the question were posed to you in a forum?

 

 

GC HLT540 week 2 dq 1 & dq 2

 

dq 1

 

What kinds of extraneous variables (not cited in the studies) do you think could have affected the relationships between the independent variables and the dependent variables in both the Messina et al. and Coyne et al. studies?

dq 2

How effectively do you think the Coyne et al. study and the Messina et al. study both used their review of literature to help the reader understand why the research question was asked? How could they have done it more effectively?

 

 

 

GC HLT540 week 3 dq 1 & dq 2

 

dq 1

 

Given that there is a documented advantage to the use of an experimental and control group design, discuss why other designs are frequently used, and the situations that may prompt the use of one.

 

dq 2

 

Discuss your understanding of the concept of internal validity in a research study, and the impacts of several errors or biases that can reduce the study’s validity.

 

 

GC HLT540 week 4 dq 1 & dq 2

 

dq 1

 

Why do you think so many people have problems with using, interpreting, or applying statistics in making business decisions?

 

dq 2

 

As you have learned to evaluate different research studies, what elements seem the most important to you for evaluation of the research’s quality? Why?

 

 

GC HLT540 week 5 dq 1 & dq 2

dq 1

 

Discuss the concept of the normal distribution, why it is important, and what you think it means.

 

dq 2

 

When students talk about “grading on the curve,” how does that apply to the normal distribution?

 

 

 

GC HLT540 week 6 dq 1 & dq 2

 

dq 1

 

Discuss the differences between the concepts of correlation and causality, and why it is critically important to make sure that the differences are understood?

 

dq 2

 

What are the indicators for using a t-test? Create a research scenario in which it would be correct to use a t-test, including the research question, sample size, and dependent and independent variables.

 

 

 

 

GC HLT540 week 7 dq 1 & dq 2

 

dq 1

 

What are the indicators for using an ANOVA? Create a research scenario in which it would be correct to use an ANOVA, including the research question, sample size, and dependent and independent variables.

 

dq 2

 

What are the indicators for using a regression analysis? Create a research scenario in which it would be correct to use a regression analysis, including the research question, sample size, and dependent and independent variables?

 

 

 

GC HLT540 week 8 dq 1 & dq 2

 

 

dq 1

 

Re-visit the roadmap that you began at the start of your program of study. Complete information regarding this course. In the discussion, reflect on how this course meets your career goals. What have you gleaned from the course that will help you in your career path? Respond to at least two other classmates.

 

 

dq 2

 

Discuss your thoughts about the ethics of using informed consent vs. blinding the subjects to the expected outcomes of the intervention. Should they be told? How much should they be told? How would the placebo effect be impacted if subjects are told which intervention is being applied to them?

 

 

HLT540 week 2 Evidence-Based Research Interview Assignment

 

Details:

Identify, analyze, and discuss the components that comprise a valid evidence-based research study.

Based on the information compiled above, interview a health care leader about his/her experiences related to using evidence-based research to drive changes in practices in his/her facility.

Write a report (1,000-1,250 words) of your findings. Include the following in your report:

1) The changes that the health care leader has been involved in implementing.

2) How strong did the leader feel the research on the topic was? Why?

3) Have they ever rejected research findings? Why or why not?

4) Include any concerns they have had or resistance they have experienced when implementing changes based on research.

5) Analyze your findings as they apply to the components of evidence-based research.

Prepare this assignment according to the APA guidelines found in the APA Style Guide, located in the Student Success Center. An abstract is not required.

This assignment uses a grading rubric. Instructors will be using the rubric to grade the assignment; therefore, students should review the rubric prior to beginning the assignment to become familiar with the assignment criteria and expectations for successful completion of the assignment.

 

 

HLT540 week 3 Assessing a Research Study Assignment

 

Details:

1) Choose a research study article of interest to you.

2) Refer to the study you choose and complete “Assessing a Research Study.”

3) Identify an article that directly references your chosen study and compare it to your findings. Does this article refute or confirm the study’s findings?

4) Write a paper (750-1,000 words) that analyzes and summarizes your findings.

5) Prepare this assignment according to the APA guidelines found in the APA Style Guide, located in the Student Success Center. An abstract is not required.

6) This assignment uses a grading rubric. Instructors will be using the rubric to grade the assignment; therefore, students should review the rubric prior to beginning the assignment to become familiar with the assignment criteria and expectations for successful completion of the assignment.

Coyne and Messina Articles Analysis

As an example guideline, review the study components in the left-side column of the table below. Read the study by Messina et al., and build the data in the right-side column with the key components in that study.

<table> <tbody><tr> <td>

Research Question:

</td> <td>

Coyne:Do size and ownership type make a difference in the efficiency and cost results of hospitals in Washington state? (Highlight p.164, second column, starting 15 lines from bottom to seven lines from bottom.)

Messina:

</td> </tr> <tr> <td>

How did the research question emerge from the review of literature in the article?

</td> <td>

Coyne:Built on an earlier study by Coyne on performance differences between multi-facility systems and independent hospitals using two cost measures. Cited studies that used a range of variables to measure differences in hospital performance, and noted that prior findings have been inconclusive in regard to hospital size, although economies of scale were found.

Messina:

</td> </tr> <tr> <td>

Independent Variables

Type:

</td> <td>

Coyne:Hospital size and hospital ownership structure.

Categorical

Messina:

</td> </tr> <tr> <td>

Dependent Variables

Type:

</td> <td>

Coyne:Efficiency measures – continuous variables.

Cost measures – continuous variables.

Messina:

</td> </tr> <tr> <td>

Design Elements

1. Quantitative vs. Qualitative

2. Sample Size

3. Method of sample selection

4. Experimental vs. control group?

5. Reliable and valid data instruments?

</td> <td>

Coyne:

Quantitative

96

Picked all hospitals in state, except investor owned hospitals.

No

Used data that are commonly used to measure hospital efficiency and performance with high degrees of accuracy (reliable), and data that are historically used and make sense to other hospital users (valid).

Messina:

</td> </tr> <tr> <td>

Describe analysis.

What statistics were used?

</td> <td>

Coyne:Two-way Analysis of Variance (ANOVA)

Messina:

</td> </tr> <tr> <td>

Did the researchers’ conclusions make sense, did they answer the research question, and did they appear to flow from the review of the literature?

Did they explore control of extraneous variables?

</td> <td>

Coyne:They concluded that size and ownership type make a difference in reported levels of efficiency. Not for profits seem to achieve higher performance levels, and medium and large not for profits operate more efficiently than industry average. The same results were found for cost levels, in that size and ownership type do make a difference, with medium sized hospitals reporting
