The study aimed to evaluate the impact of a POCUS workshop on students' knowledge, with a required sample size of 70 participants for validity. Here's a summary of the findings based on the Wilcoxon Signed-Rank Test and Cohen's d effect size:
Statistical Significance (p-value)
- Principles of POCUS: p-value = 0.0006 (statistically significant)
- Image Acquisition: p-value = 0.0837 (not statistically significant)
- E-Fast: p-value = 0.00003 (statistically significant)
- Vascular: p-value = 0.00009 (statistically significant)
Effect Size (Cohen's d)
- Principles of POCUS: Cohen's d = 0.24 (small effect)
- Image Acquisition: Cohen's d = 0.23 (small effect)
- E-Fast: Cohen's d = 0.57 (medium effect)
- Vascular: Cohen's d = 0.56 (medium effect)
Summary
The POCUS workshop significantly improved students' knowledge in the areas of Principles of POCUS, E-Fast, and Vascular assessments, as indicated by statistically significant p-values and small to medium effect sizes. Although the improvement in Image Acquisition was not statistically significant, the overall results suggest that the workshop effectively enhanced students' understanding and skills in POCUS.
Given that the required number of participants was met, and the results show significant improvements in key areas, it can be concluded that the POCUS workshop is effective in improving students' knowledge of POCUS.
