An antenatal risk scoring form was devised. The form contains 23 risk factors in three categories: reproductive history, associated medical conditions, and the present pregnancy. Numerical scores were arbitrarily assigned to each factor. The form was applied retrospectively to 1175 deliveries, and a total score was obtained for each case. The total score was related to perinatal death, preterm birth, Apgar score, and low birth weight. It was found that increasing score was significantly associated with poor outcome. The scores were grouped into low risk, high risk, and extreme risk. This system identified 25% of the study population as high and/or extreme risk, which in turn accounted for 94% of perinatal deaths. Although such a form in general has potential limitations and should not replace clinical judgment, its simplicity and demonstrated ability to assist in high-risk selection refines risk assessment for the experienced physician and quantifies it for the neophyte. It is recommended that the form be included in the prenatal records of all patients. Obstetricians have long recognized the need for varying levels of care. Pregnant patients with certain complications have an increased chance of having a complicated pregnancy course and an infant who has a complicated course; therefore,these patients require more intensive observation and care than usual. However, in our communities, well-trained personnel and resources are limited. The accurate identification of patients requiring different levels of care is a major concern, for both the individual physician and the patient and in planning regional perinatal resources. A number of high-risk pregnancy scoring systems have been proposed, 1-6 but in general, information derived from them has not proved discernibly superior to expert clinical judgment. Many of the scoring forms are too extensive andcomplicated to be filled out by a busy clinician, without whose enthusiastic cooperation no screening system can ever be expected to function effectively. In addition, not all of the known risk factors in pregnancy are universally applicable. It has been shown that some of the accepted risk factors may not have the
