Declining cesarean delivery rates in California: an effect of managed care?

Article Abstract:

Managed care does not appear responsible for the decline in the number of cesarean deliveries in California. Researchers analyzed the cesarean rate among more than six million deliveries in California between 1983 and 1994. California was chosen because it has the highest penetration of managed care. The cesarean rate in California rose from 21.6% in 1983 to 25% in 1987, then dropped to 21% by 1994. However almost all of this decline was due to a reduction in repeat cesareans in women who had a prior cesarean.

Predicting cesarean delivery with decision tree models

Article Abstract:

Decision tree models are described that can predict which pregnant women are likely to require a cesarean delivery. The models incorporate well-known risk factors for a cesarean delivery, including previous cesarean delivery, maternal diabetes or hypertension, preeclampsia, abnormal fetal presentation, twin pregnancy, and a displaced placenta.
