| Pre | Post | Test statistic | p value | |
|---|---|---|---|---|
| Knowledge | ||||
| Reasons for using CHG: correct | 32 (35.56%) | 32 (35.56%) | χ2 = 0 | 1.0 |
| Facts about CHG: correct | 28 (31.11%) | 45 (50.0%) | χ2 = 9.32 | .002 |
| CHG decreases CLABSI | 3.11 (0.76) | 3.24 (0.84) | t = 1.27 | .21 |
| Perception | ||||
| Importance of bathing | 3.30 (0.73) | 3.28 (0.78) | t = − 0.33 | .74 |
| Priority of bathing | 2.68 (0.77) | 2.74 (0.77) | t = 0.82 | .41 |
| Importance of CHG bathing | 2.81 (0.93) | 2.93 (1.01) | t = 1.37 | .17 |
| Priority of CHG bathing | 2.60 (0.79) | 2.79 (0.75) | t = 2.56 | .01 |
For “Knowledge: reasons for using CHG” and “Knowledge: facts about CHG,” n-size and percent correct are reported, and McNemar’s chi-square tests are reported to assess change. For remaining items, means and standard deviations are reported, and paired t tests are used to assess change
