[The reduction of prematurity by telephone follow-up]

Twice-daily check-up of the uterine contractions by the pregnant women is a recognized and accepted necessity. Using the "green" free-phone number to report the number of contractions, to answer the questions asked and to receive the instructions given has made it possible to reduce the prematurity rate and the duration of the consequent specific hospitalization. This new method of follow-up, applied to two identically recruited groups of pregnancies offers an undeniable low-cost improvement over the systems used previously.
