In a recently published study, a poor knowledge of guidelines in the field of early pregnancy was observed in France, Belgium and Switzerland. To improve the respect of the most recent criteria of diagnoses, a computerized tool was developped.

In December 2018, the investigators published an prospective multinational survey, with 17 questions that assessed the participants' knowledge, interest, and management of early pregnancy in France, Belgium and Switzerland1. Knowledge about early management of pregnancy was limited among the practitioners surveyed ; 211/306 (69.0%) participants reported incorrect management when they visualized a gestational sac without embryo and 265/306 (86.6%) misinterpreted changes in serum levels of chorionic gonadotropin during early pregnancy.

To fill this gap, the investigators developped a computerized tool who is following strictly the most recent criteria of diagnoses in the field of early pregnancy. This tool should be evaluated in an observational study, using data of real patients without modification of their management.
