Quantitative Article: The effect of Aloe Vera gel on prevention of pressure ulcers in patients hospitalized in the orthopedic wards: a randomized triple-blind clinical trial
Background or Introduction (A1)
The aim of the study is to explore how effective Aloe Vera would be in the prevention of pressure ulcers in a patient admitted to the orthopedic unit. Based on several studies there is evidence to prove that components in aloe vera play a part in healing and reduction of inflammation, so these researchers wanted to see if there would be some effect on pressure ulcers also.
Review of the Literature (A1)
The article did not have a section called a literature review. The author discussed past publications in the first section. The author cited 75 past publications. A couple of the topics that the researchers use include
1. Protecting 5 million lives from harm. USA: Institute for Healthcare Improvement;
2. Effect of coconut oil usage on the risk of pressure ulcers among bedridden patients of selected hospitals in North India,
3. An economic appraisal of the Australian medical sheepskin for the prevention of sacral pressure ulcers from a nursing home perspective
4. Preventing pressure ulcers with the Australian medical sheepskin.
5. Effects of hydrocolloid dressing in the prevention of bed sore in patients undergoing coronary artery bypass surgery.
One of the cited studies reflects that products such as amino acids and zinc found in aloe vera help with the health of the skin, reducing its ability to develop an ulcer.
Data Analysis (A1)
Several tools were used to analyze the data in this research, descriptive statistics were used to pull out information for the charts and tables. Chi-square tests, Fisher's exact test, independent t-test, ANOVA, and Friedman were used for interpretation.
Discussion of Methodology (A1)
The method uses to complete this study was a triple-blind randomized two-group clinical trial. Eighty (80) patients were randomly assigned to 2 groups, control, and intervention with 40 participants in each. The pressure ulcer areas studied were assessed for 10 days and the information was gathered based on the number of patients.
Quantitative: Conclusions (A2)
The aim in the introduction was supported by the research's conclusion where it was shown that aloe vera was indeed effective in the prevention of pressure ulcers. The review of the literature showed where the researcher uses several past publications to outline how different studies were done before and that support the researcher's conclusion that based on comparison to other treatment, aloe vera is less costly. In the data analysis, the different test that was used to measure and interpret the data supports the researcher's conclusion that between the intervention and control groups there were statistically significant differences in terms of ...
