Methods
We conducted a case-control study of women who delivered at our institution between 2010 and 2014. We compared pregnant women with Hepatitis C antibody (cases) to those without Hepatitis C antibody (controls). Controls were chosen at a ratio of 1:5 and matched for maternal age and race. We assessed postpartum infections which was a composite of endometritis, wound infection, perineal cellulitis, retained products of conception, urinary tract infection, and septic pelvic thrombophlebitis attained from coding. We adjusted for other factors associated with postpartum infection including gestational age, marital status, BMI, smoking status, drug status and gestational diabetes. We also assessed whether mode of delivery affected development of postpartum infection although the study was not powered for this. Odds ratios (OR) and 95% confidence intervals (CI) were calculated.
