Walden University – NURS 4100 – Week 4 Assignment

What was the purpose of the study (research questions, purposes, and hypotheses)?

How was the sample obtained?

What inclusion or exclusion criteria were used?

Who from the sample actually participated or contributed data (demographic or clinical profile and dropout rate)?

What methods were used to collect data (e.g., sequence, timing, types of data, and measures)?

Was an intervention tested?

How was the sample size determined?

Were patients randomly assigned to treatment groups? What are the main findings?

Is the study published in a source that required peer review?
Was the design used appropriate to the research question?
*Did the data obtained and the analysis conducted answer the research question?
Were the measuring instruments reliable and valid?
*Were important extraneous variables and bias controlled?

*Was the study free of extraneous variables introduced by how, when, and where the study
was done?
*If an intervention was tested, answer the following five questions:
1. Were participants randomly assigned to groups and were the two groups similar at the start (before the intervention)? Not randomly assigned but they were similar at the start.
2. Were the interventions well defined and consistently delivered?
3. Were the groups treated equally other than the difference in interventions?
4. If no difference was found, was the sample size large enough to detect a difference if one existed?
5. If a difference was found, are you confident it was due to the intervention?
Are the findings consistent with findings from other studies?
Are the findings credible?

Clinical Significance
Note any difference in means, or measures of clinical effects (ABI, NNT, RR, OR).
Intervention was only carried out on one floor so it was consistent.
*Is the target population clearly described?
*Is the frequency, association, or treatment effect impressive enough for you to be confident
that the finding would make a clinical difference if used as the basis for care?

Are the findings clinically significant?

This was both a qualitative and quantitative study.

Clinical Significance
*Are the findings rich and informative?
*Is the perspective provided potentially useful in providing insight, support, or guidance
for assessing patient status or progress?
Yes, it is a good start on insight of wear practices are missed.
What experience, situation, or subculture does the researcher want to understand?

Does the researcher want to produce a description of an experience, a social process, or an event, or is the goal to generate a theory?
Are specific pieces of data (e.g., direct quotes) and more generalized statements (themes, theories) included in the report?
