Evaluating the clinical utility of cervical cultures in postpartum endometritis management.

To evaluate the utility of cervical cultures in the diagnosis and management of postpartum endometritis. A retrospective study was conducted on 1069 cervical cultures collected from postpartum women with suspected endometritis between 2011 and 2021. Patient demographics, obstetric history, clinical parameters, and culture results were analyzed. Microorganisms were categorized into five groups based on species and virulence. Statistical analysis was performed to identify associations between risk factors, pathogens, and disease severity. The positivity rate for distinct microorganisms in cervical cultures was 33.1%. Escherichia coli (10.8%) and Group B Streptococcus (7.5%) were the most common isolates. Prolonged labor duration and prolonged rupture of membranes were associated with Enterobacterales infections. Elevated white blood cell count was linked to Enterobacterales and beta-hemolytic Streptococci, while the former were also associated with higher rate of postpartum clinic visit. No significant differences in disease severity were found between other microorganism groups. The study suggests that while cervical cultures can identify potential pathogens in postpartum endometritis, their clinical utility is questionable due to the polymicrobial nature of the disease and the isolation of commensal microorganisms. The lack of significant differences in disease severity across various microorganism groups raises questions regarding the contribution of distinct bacterial identification in endometritis management.
