National Vital Statistics Reports Essay

Question:

Give a brief discussion on roddy analysis and ganz analysis?

Answer:

Roddy Analysis

The main purpose of this article is to develop a new method to determine the true strength of recommendation with help of the research evidence and expert opinion (Arias, Heron, & Tejada-Vera, 2012). For this purpose a Delphi technique is used to produce 10 recommendations to determine the role of exercise therapy in osteoarthritis of the hip or knee and determine the strength of recommendation and grade each recommendation with basis of the two categories- category of evidence and strength of recommendation. In addition with this traditional process here a new method is applied, all the patients are asked to point out how strongly they give ratings to each recommendation. A 10 cm visual analogue scale is used to record the patients’ opinions. For all the patients the research question was how strongly they rated each recommendation (Mini?o, et al, 2011) . In the traditional approach strength of recommendation highly related with the category of evidence, therefore strength of recommendation is dependent variable and category of evidence is independent variable (Hoyert, & Xu, 2012). To overcome this problem this new method is developed. This new system of grade power of SOR is less controlled than the traditional methodology and offers the benefit of allowing SOR for measures which cannot be assess in RCTs for practical or moral reasons to upgrade according to expert view (Murphy, Xu & Kochanek, 2013).

What was the research question?

Whether the new system is better to determine the true strength of recommendation

What were the independent variables?

What was the dependent variable?

strength of recommendation is dependent variable and category of evidence is independent variable

What was the sample size and how was it chosen?

Some patients are asked to rated each recommendation

What was the experimental design and use of control group?

Here the experimental design is SOR-VAS.

Were the instruments of measurement shown to be reliable and valid?

The instrument of measurement shown to be reliable and valid

What data types were included?

The data types are nominal or ordinal

Describe the statistics used, what they were used for, and the results.

Here mean and standard deviation of vas score is calculated for each recommendation group, and ANOVA method is used to test whether there is difference among the group

What were the researchers’ conclusions? How did they answer the research question(s)?

This new system of grade power of SOR is less controlled

than the traditional methodology and offers the benefit of

allowing SOR for measures which cannot be assess in RCTs for practical or moral reasons to upgrade according to expert view.

How was error controlled?

The error in the traditional SOR system is controlled in this new system by allowing the SOR to upgrade or downgrade with respect to the expert opinion relating generalizability, safety, common sense, and cost effectiveness

Did you see any concerns with the research study? If so, what?

There is a limitation in the new VAS-SOR system. This new system does not depend on explicit criteria, this system does not examined and assessed by external groups.


Ganz Analysis

Main purpose of this article is to compare the oral care practice with current evidence based practice of ICU nurses and determine whether EBP is related with personal demographic or professional characteristics (Kochanek, et al, 2012). For this purpose a sample of 218 ICU nurses are considered. A questionnaire is set up and the nurses are asked to answer those questions. This questionnaire consists of the questions regarding demographic and professional characteristics and a checklist of oral care and current evidence based practice. A descriptive statistics and frequency data is used to explain the sample of oral care practice (Hamilton, et al, 2013). And analysis variance method is used to test whether EBP is related with demographic or professional characteristics. After that Cronbach’s alpha statistics is used to check the reliability of the test (Osterman, et al, 2015). After performing this procedure the researcher are concluded that though the ICU nurses consider oral care as a high level of priority, the evidence based performance level is relatively low. And EBP is not related with demographic and professional characteristics (Martin, et al, 2012).

What was the research question?

Comparison of oral care practice with current evidence based practice of ICU nurses and determine whether EBP is related with personal demographic or professional characteristics

What were the independent variables?

What was the dependent variable?

Current evidence practice is dependent variable and personal demographic or professional characteristics are independent variables

What was the sample size and how was it chosen?

A sample of 218 ICU nurses are selected for this purpose

What was the experimental design and use of control group?

The experimental design is describe the oral care practices, then compare this oral care practices with current evidence based practices and test whether these practices are related with demographic or professional characteristics

Were the instruments of measurement shown to be reliable and valid?

Since the questionnaire is a

checklist use of Cronbach’s alpha for this tool was

not appropriate. Cronbach’s alpha is used to check the reliability of test.

What data types were included?

Some data are numerical and some are categorical

Describe the statistics used, what they were used for, and the results.

Descriptive statistics and data are used here. Also a analysis of variance method (ANOVA) is used to test the hypothesis

What were the researchers’ conclusions? How did they answer the research question(s)?

According to the researcher though the ICU nurses consider oral care as a high level of priority, the evidence based performance level is relatively low. And EBP is not related with demographic and professional characteristics

How was error controlled?

Error was controlled by calculating the Cronbach’s alpha statistics for deleted item and after deletion if the value of the Cronbach’s alpha increases then exclude the item from the list

Did you see any concerns with the research study? If so, what?

Among the ICU nurses no one could explain for oral care what assessment tool was used.
