Visual representation of data is critical for understanding and interpreting the effectiveness of the intervention. Hand hygiene compliance was depicted through a bar chart displaying monthly compliance rates before and after the intervention. This visualization highlighted a significant improvement, with compliance rates increasing from an average of 60% pre-intervention to 85% post-intervention. Such a marked increase underscores the intervention's success in fostering better hygiene practices among the CVRU staff. HAI rates were shown using a line graph, illustrating the trend in infection rates over the intervention period. This graph depicted a substantial reduction in HAI rates, dropping from 4.5 infections per 60 patient days to 2.0 infections per 60 patient days. The correlation between improved hand hygiene compliance and reduced HAI rates was evident, demonstrating the intervention's effectiveness.

The analysis of this data involved examining the relationship between hand hygiene compliance and HAI rates. The inverse correlation observed suggests that as compliance rates improved, HAI rates declined. This analysis was supported by statistical tests that confirmed the significance of the observed trends. The visual and analytical representation of data provided a clear narrative of the intervention's impact, highlighting the critical role of hand hygiene in preventing HAIs.
