Multivariable logistic regression analysis for risk factors associated with SSI at the UCC of Kosovo, Clinic for Obstetrics and Gynecology
| Variables a | B | S.E. | Wald | Df | Sig. | Exp(B) | 95% C.I. for EXP(B) | |
|---|---|---|---|---|---|---|---|---|
| Lower | Upper | |||||||
| Age < 35 | 0.815 | 0.469 | 3.019 | 1 | 0.082 | 2.26 | 0.901 | 5.667 |
| Co-morbidity (yes) | 1.995 | 0.5 | 15.929 | 1 | 0.000 | 7.354 | 2.761 | 19.593 |
| Antibiotics (yes) | −1.509 | 0.454 | 11.03 | 1 | 0.001 | 0.221 | 0.091 | 0.539 |
| Duration of surgery (< 1 h) | − 1.31 | 0.55 | 5.666 | 1 | 0.017 | 0.27 | 0.092 | 0.793 |
| Previous C-section (yes) | 1.296 | 0.508 | 6.513 | 1 | 0.011 | 3.654 | 1.351 | 9.887 |
Multivariable logistic regression analysis confirmed that one or more co-morbidity, previous C-section, preoperative antibiotics and duration of the surgery < 1 h are predictors of SSI
a Variable (s) entered on step 1: age, co-morbidity, antibiotics, duration of surgery, previous C-section
