Predictors of resistance in staphylococcal hand flora of nurses, as analyzed by logistic regression*
| Organism | Antibiotic (No. isolates tested) | Significant variables | Relative risk (95% CI) |
|---|---|---|---|
| Staphylococcus epidermidis | Oxacillin (n = 478) | Hand product | |
| Alcohol | Referent | ||
| Antiseptic soap | 1.92 (1.08−3.43) | ||
| Gentamicin (n = 472) | Hand product | ||
| Alcohol | Referent | ||
| Antiseptic soap | 1.50 (1.00−2.27) | ||
| Staphylococcus warneri | Gentamicin (n = 447) | Skin Condition | |
| Healthy | Referent | ||
| Damaged | 2.79 (1.35−5.81) | ||
| Rifampin (n = 463) | Hand product | ||
| Alcohol | Referent | ||
| Antiseptic soap | 7.22 (2.97−17.56) |
Predictor variables included in each model: hand product, skin condition, years worked on unit, and site (NICU 1 or 2).
