Research Article Critique, Part Three
Instrucdons: A major skill that is learned in this course is how to critically read and critique nursing research articles. The purpose for critiquing an article is to critically evaluate the research process followed by the author(s) of the assigned article. This is an information-intensive, time-intensive process that is not learned overnight. To demonstrate your skill at critiquing an article, you will complete this open-book multiple choice assignment
Here’s how you should approach completing this week’s assignment to begin critiquing an article:
t First, do your assigned reading in Grove & Gray (2019) and complete the reading worksheets early in the week. This will introduce you to the critique skills you will need for the week.
2. Skim the entire instructor assigned research article that has been posted in Canvas for you so that you will have an idea of what it is about. Lightly cross out the abstract for the article (you won’t be using it). Then, for this week, re-read carefully the from the methods section through the end of the article. 3. Print the Research Article Critique, Part Two and find the best answer to each question based on your Grove & Gray (2019) assigned reading for the week and on what you have read in the instructor assigned research article.
4. Some of the questions in the critique assignment below will seem unfamiliar to you. Look up key terms from the question in your textbook. Some examples of these terms might be: problem statements, hypotheses, or variables. You can also I.k in Chapter 12 for an example of a critical appraisal (or critique) of a quantitative research article.
5. Once you have completed this assignment “on paper”, go into blackboard and enter your answers by the assignment due date and time listed in the syllabus. If you have questions about this assignmeM, you can post them to the Q &A board for help. Please do not post the exact question from the ossisnment below and ask the group for the answer as this would constitute academic dishonerty. Your assigned article for critique Is: Avsar, P., Budri, A., Patton, D., Walsh, S., & Moore, 1(20221.

The study aimed to investigate the relationship between activity, mobility, and pressure ulcer (PU) development among older adult residents in long-term care. It also aimed to develop an algorithm for detecting PU risk based on activity and mobility levels.
A total of 53 older adult residents were followed prospectively for 4 days. Their Braden scores, Elderly Mobility Scale scores, and movement levels were assessed. Movement was measured objectively using a sensor that counted movements.
Key findings included a 15.1% incidence of visual skin assessment-detected PUs. Movement levels were not significantly correlated with Braden or Elderly Mobility Scale scores. Both low and high movers developed PUs.
The researchers concluded that current PU risk assessment tools may not accurately capture movement-based risk. An algorithm incorporating objective movement data could help identify at-risk individuals among both low and high movers.
Implications for practice include considering movement-based assessments to supplement existing tools. Real-time movement monitoring may enable early detection and targeted prevention strategies.
Further research is still needed to establish standardized movement-based algorithms and classifications for PU risk stratification. Prospective studies incorporating movement data could help validate algorithm-based approaches.
