Inpatient vs Outpatient Management of Short Cervix

The presence of short cervix during pregnancy is a risk factor for preterm birth though in many cases women will eventually deliver at term or near term. While there are proven treatments such as cerclage and progesterone that can improve pregnancy outcomes, many women are advised to limit their activity, are put on bed rest, or admitted to hospital for inpatient management. Presently, there is no evidence that hospital admission of women with short cervix is beneficial and prolongs the pregnancy. The investigators propose to examine whether inpatient management results in comparable outcomes to outpatient management for women with short cervix.
