Table 1 Comparison between baseline median CFU and post cleaning median CFU for each cleaning agent
From: Use of 90% ethanol to decontaminate stethoscopes in resource limited settings
Cleaning agent | Baseline Median CFU (IQR) | Range of Variation | Post cleaning Median CFU (IQR) | Range of variation | Percent reduction in CFU (mean) | P value for Wilcoxon signed-rank test |
|---|---|---|---|---|---|---|
IPA | 22.5 (7–48) | 0–110 | 0 (0–0) | 0–21 | 93.14% | <0.001 |
90% ethanol | 17.5 (7–31) | 0–106 | 0 (0–0) | 0–5 | 97.60% | <0.001 |
