  • 1Department of Obstetrics and Gynecology, Kangwon National University School of Medicine, Chuncheon, Korea


High-risk pregnancy is the probability of adverse pregnancy out come is increased over the general pregnant population. Some high-risk pregnancy is the result of a medical condition present before pregnancy. In other cases, a medical condition that develops during pregnancy causes a pregnancy to become high risk. The reason why high-risk pregnancy is importa nt is detecting the risk factors for high risk pregnancy early and preventing the complicated pregnancy. Korean society of Obstetrics and Gynecology (KSOG) announced the classification of high-risk pre gnancy including 95 risk factors: obstetrics risk factors, medical risk factors, physical risk factors and risk factors of current pregnancy. However, this announcement of high-risk pregnancy by KSOG was limited for maternal-fetal healthcare providers to apply their working and making policy. First this didn't include the conception of the complicated pregnancy and high-risk delivery. Second this did not separate the risk factors depend on before and during pregnancy. This review briefly evaluates the classification of high-risk pregnancy by KSOG and suggest the new classification including the complicated pregnancy and high-risk delivery for maternal-fetal healthcare providers.
