Multivariate analysisa of factors associated with high-level mupirocin-resistant MRSA
Variable | Odds ratio (95% CI) | P value |
---|---|---|
Multidrug-resistant MRSA isolateb | 2.69 (1.37, 5.28) | 0.004 |
History of MRSAb | 2.34 (1.75, 3.12) | <0.001 |
Avg ADL scorec | 1.25 (1.07, 1.45) | 0.004 |
Note that four psychiatric facilities were removed from the multivariate analysis.
Analyzed as a resident-level or isolate-level variable, not as a facility-level variable.
The ADL score ranges from 0 (completely independent) to 28 (completely dependent) and is expressed per 1 point increase. The reported average ADL score is the average score among all residents of one facility. The ADL score was colinear with the presence of indwelling devices.
