HLT 540 Grand Canyon Week 1 Discussion 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?
HLT 540 Grand Canyon Week 1 Discussion 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?
HLT 540 Grand Canyon Week 2 Discussion 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?
HLT 540 Grand Canyon Week 2 Discussion 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?
HLT 540 Grand Canyon Week 3 Discussion 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.
HLT 540 Grand Canyon Week 3 Discussion 2

HLT 540 Grand Canyon Week 4 Discussion 1
Why do you think so many people have problems with using, interpreting, or applying statistics in making business decisions?
HLT 540 Grand Canyon Week 4 Discussion 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?
HLT 540 Grand Canyon Week 5 Discussion 1

distribution?
HLT 540 Grand Canyon Week 6 Discussion 1

HLT 540 Grand Canyon Week 8 Discussion 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?

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.
Research Question:
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 the bottom.)
Messina:
How did the research question emerge from the review of literature in the article?
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:
Independent Variables
Type:
Coyne:
Hospital size and hospital ownership structure.
Categorical
Messina:
Dependent Variables
Type:
Coyne:
Efficiency measures – continuous variables.
Cost measures – continuous variables.
Messina:
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?
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:
Describe analysis.
What statistics were used?
Coyne:
Two-way Analysis of Variance (ANOVA)
Messina:
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?
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 lower costs than large or small hospitals.
Yes, when they called for national studies that controlled for case mix, scope of services, and payer mix, all of which could have affected the results in this study in an unmeasured way.
