Nearly one of four of cesarean deliveries performed for "lack of progress in labor" may be carried out too early during the birth process, according to a new study funded by the Agency for Healthcare Research and Quality. Researchers found that up to 24% of the 294,000 cesarean deliveries performed annually in the United States for lack of progress were in women with a dilation of only 0 to 3 cm. This practice is contrary to the American College of Obstetrics and Gynecology's recommendation that the cervix be dilated to 4 cm or more before a diagnosis of lack of progress of labor.
