Realtors rely on detailed property appraisals—conducted using appraisal tools—to assign market values to houses and other properties. These values are then presented to buyers and sellers to set prices and initiate offers.
Research appraisal is not that different. The critical appraisal process utilizes formal appraisal tools to assess the results of research to determine value to the context at hand. Evidence-based practitioners often present these findings to make the case for specific courses of action.
In this Assignment, you will use an appraisal tool to conduct a critical appraisal of published research. You will then present the results of your efforts.
To Prepare:
- Reflect on the four peer-reviewed articles you selected in Module 2 and the four systematic reviews (or other filtered high-level evidence) you selected in Module 3.
- Reflect on the four peer-reviewed articles you selected in Module 2 and analyzed in Module 3.
- Review and download the Critical Appraisal Tool Worksheet Template provided in the Resources.
The Assignment (Evidence-Based Project) Part 3A: Critical Appraisal of Research
Conduct a critical appraisal of the four peer-reviewed articles you selected by completing the Evaluation Table within the Critical Appraisal Tool Worksheet Template. Choose a total of four peer- reviewed articles that you selected related to your clinical topic of interest in Module 2 and Module 3.
Note: You can choose any combination of articles from Modules 2 and 3 for your Critical Appraisal. For example, you may choose two unfiltered research articles from Module 2 and two filtered research articles (systematic reviews) from Module 3 or one article from Module 2 and three articles from Module 3. You can choose any combination of articles from the prior Module Assignments as long as both modules and types of studies are represented.

A Braden score of ≤18 was used to determine need for prevention in n = 3 studies.Cost of pressure ulcer prevention was between 37,699 & 405,523 euros per 100,000 habitants. | Commonest study design were RCTs (n = 6).Support surfaces, staff education, and repositioning with early mobilization were the dominant interventions. | Difference in hip temperature (p = 0.0001).Increasing pain in control group cf to study group (p = 0.003) | Effect size (silicon foam dressing strategy) = 4.62, 95% CI, p <0.00001. |
| Findings and RecommendationsGeneral findings and recommendations of the research | It was cheaper to prevent pressure ulcers than to treat ulcers that had already occurred. | Effective interventions for prevention: repositioning & early mobilization, support surfaces, prophylactic dressings, risk assessment tools like Braden scale, skin care, & staff education. | Alternative natural therapies such as aloe vera could be effective in preventing the development of PUs. | Use of silicon foam dressing strategy effective at PU incidence reduction. |
| Appraisal and Study QualityDescribe the general worth of this research to practice.
What are the strengths and limitations of study? What are the risks associated with implementation of the suggested practices or processes detailed in the research? What is the feasibility of use in your practice? |
The research is invaluable for practice in terms of preventative practice.The main strength of the study is that it is a level I evidence study.
The limitations include that it is not primary research, broad methodological heterogeneity, and publication bias. The risk of applying the suggested practices is loss of fiscal resources in futile prevention. He study is very feasible n practice. |
Research is important for clinical practice.Strength is that it is a level I evidence study.
Limitations include that it is not primary research and that methodological errors in the included studies would be transferred to the systematic analysis. Risks of implementing the recommendations are in using some of them in isolation, which is not effective. The study findings are very feasible in applicability to practice. |
The research is very important to practice.The strengths include being a primary study, being of experimental design, & being triple blinded.
The limitation is basically the initial purposive sampling. Risks associated with implementing the intervention is neglect of conventional interventions. The application of aloe vera is feasible in practice. |
Study crucial for practice.Strength is in being a level I evidence study.
Limitations include not being a primary study and error duplication from the component studies reviewed. The risk is applying an intervention whose reported efficacy was based on faulty methodology or research design. The findings are easy to implement in practice, meaning feasibility is high. |
| Key findings | Prevention of pressure ulcers is cheaper than treatment of the same. | A bundled approach of several measures as outlined above is effective. | Aloe vera as a natural alternative therapy is effective in preventing the occurrence of PUs. | Silicon foam dressing is effective in reducing the chances of developing PUs |
| Outcomes | Savings on pressure ulcer prevention. | Reduced PU incidence with preventive measures. | Lower rates of PUs in the study group. | Reduced incidence rate for PUs. |
| General Notes/Comments | The study enriches evidence-based practice (EBP) by providing evidence for prevention. | The study increases EBP knowledge (Melnyk & Fineout-Overholt, 2019). | Considering alternatives in complementary and alternative medicine (CAM) remedies is an act of beneficence (Haswell, 2019). | This study is instrumental in increasing EBP knowledge (Melnyk & Fineout-Overholt, 2019). |
Part 3B: Critical Appraisal of Research
Evidence-based practice is unique compared to common practice in that it makes use of only those interventions that have proven efficacy supported by scholarly evidence. This evidence is in the form of research that is peer-reviewed and published in reputable journals (Melnyk & Fineout-Overholt, 2019).
Evidence-Based Practice (EBP) Part 3: Critical Appraisal of Research.
Pressure ulcers are some of the most concerning hospital-acquired conditions that reduce the quality of healthcare. Hey are effectively a quality benchmark used to evaluate the quality of care offered by healthcare institutions by quality enforcement organizations such as the Joint Commission on Accreditation of Healthcare Organizations (JCAHO). Pressure ulcers being a quality improvement (QI) issue, there is need to institute clinical inquiry into evidence-based interventions that can prevent them. In this case, four peer-reviewed studies have been critically appraised and found to offer some of the strategies that are efficacious and able to accomplish the task.
Evidence-Based Practice (EBP) Part 3: Critical Appraisal of Research.
The studies propose the best practice (EBP) through the following measures:
- Allocating fiscal resources on pressure ulcer prevention strategies because studies show that the financial input required to treat PUs after they have occurred are more (Demarré et al., 2015). In other words, it is more expensive to treat PUs than to prevent them.
- Bundled interventions in the form of repositioning & early mobilization, support surfaces, prophylactic dressings, risk assessment tools like Braden scale, skin care, & staff education have evidence backing them as effective PU preventive measures (Gaspar et al., 2019).
Evidence-Based Practice (EBP) Part 3: Critical Appraisal of Research.
- Alternative natural remedies such as aloe vera are also efficacious in preventing PUs, according to scholarly evidence available (Hekmatpou et al., 2018).
The use of silicon foam dressing is also an evidence-based strategy that is effective in preventing pressure ulcers (Tayyib & Coyer, 2016). Evidence-Based Practice (EBP) Part 3: Critical Appraisal of Research.
