Table 3 Stratified comparison of bacterial reduction between two cleaning methods and cleaning effect within method and surface
From: A comparison of two cleaning methods applied in a small animal hospital
Surface | Strata before cleaning | Number of samples scrub cleaning | Number of samples microfibre cleaning | Mean log10 reduction after scrub cleaning (95% CI) | Mean log10 reduction after microfibre cleaning (95% CI) | p-value |
|---|---|---|---|---|---|---|
Floor | < 5.0 CFU/cm2 | 10 | 6 | 0.48a (0.02–0.93) | -0.08a (-0.57-0.40) | 0.063 |
Floor | 5.0–40.0 CFU/cm2 | 9 | 14 | 1.07b (0.76–1.37) | 0.32a (-0.04-0.68) | 0.0022 |
Floor | > 40.0 CFU/cm2 | 4 | 3 | 1.46b (0.01–2.91) | 1.70b (-1.19-4.59) | 0.78 |
Wall | < 5.0 CFU/cm2 | 16 | 15 | 0.86a (0.56–1.17) | 0.40a (0.17–0.63) | 0.016 |
Wall | ≥ 5.0 CFU/cm2 | 7 | 8 | 2.13b (1.45–2.82) | 0.57a (0.30–0.83) | 0.00085 |
