Methicillin-Resistant Staphylococcus Aureus (MRSA) Prevalence in Pregnant Women and Transmission Risk to Newborns: Time to Stop Screening

Le résumé fourni par la source

Background: Methicillin-resistant Staphylococcus aureus has become problematic and threatening in an expanded segment of healthy people.Current literature cites an increase in cases of healthy pregnant women and their infants becoming infected or colonized with this organism.Aim: To determine the prevalence of MRSA colonization in women presenting for delivery and the risk of transmission from mother to infant.In addition, the utility of prophylactic treatment of colonized mothers was analyzed.Methods: This retrospective review of medical records from 3,021 births at the Greenville Hospital System University Medical Center now Prisma Health allowed determination of prevalence and incidence of MRSA infection in peripartum mothers and newborn infants.Findings: Of 102 evaluable mother/baby pairs examined, 8 were positive for MRSA in both mother and baby, providing an overall MRSA transmission rate of 7.84%.The prevalence rate of MRSA colonization in women presenting for delivery was 4.19%. Conclusions:Based on other community prevalence rates reported by Beigi, et al., [7]and Huang, et al.,[3] the 4.19% MRSA colonization rate does not necessitate prophylactic treatment for expectant mothers.From the data, it was calculated that prophylactic treatment of 442 women would be necessary to prevent the transmission to one infant.The data also supports the current recommendations discouraging broad based screening for MRSA in healthy populations with no clear risk factors for colonization.
