OB Algorithms

These algorithms are designed to assist the primary care provider in the clinical management of a variety of problems that occur during pregnancy.

They should not be interpreted as standard of care, but instead represent guidelines for management. Variation in practice should take into account such factors as characteristics of the individual patient, health resources, and regional experience with diagnostic and therapeutic modalities.
