Variable | Odds ratio | 95% confidence interval |
---|---|---|
Model 1: Urinary tract infection, mastitis, surgical site infection or episiotomy site infection following cesarean or vaginal delivery | ||
Cesarean section | 1.21 | 0.59-2.47 |
Antistaphylococcal antibiotics | 1.89 | 1.02-3.53 |
Rehospitalization within 30 days of delivery | 3.23 | 1.32-7.91 |
Ambulatory diagnosis code for mastitis, urinary tract infection, or endometritis | 5.70 | 2.97-10.95 |
Ambulatory blood or wound culture | 5.85 | 1.97-17.84 |
Hospital or emergency department diagnosis code for mastitis, urinary tract infection, or other obstetrical complications | 0 | |
Model 2. Surgical site infections (including endometritis) following cesarean section | ||
Ambulatory blood or wound culture | 9.17 | 2.44-34.41 |
