approach to GBS prophylaxis I've ever heard of--kind of a hybrid of the ACOG recommendations. No outcome data are available since we do only 450-500 deliveries/year and have evolved the approach over 6 years. Our population colonization rate is between 20-25%.

We culture all women at 36 weeks or anytime in pregnancy if they bleed or have preterm cervical change with contractions. We consider any history of positive vaginal or urine culture for GBS at any time in life to be colonized at time of labor, also anyone with history of neonatal sepsis in other infant regardless of culture result. We also regard women with negative cultures but risk factors at time of labor as colonized. We treat all positive antepartum urine cultures with ampicillin, and use Ampicillin for intrapartum prophylaxis. Status of membranes does not affect prophylaxis of colonized women, and c/s without labor also merits prophylaxis in these, at least 1 hour prior to delivery. We are aggressive as well in our efforts to identify and treat bacterial vaginosis in pregnancy. We practice in a high-risk environment for litigation.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
