Incidence and management of ectopic pregnancy have undergone significant changes in recent decades. There is a general consensus that available effective contraceptive methods reduce the absolute risk of ectopic pregnancy. Ectopic pregnancy incidence rate has not been well-documented in the last decade, and the mix of methods of contraceptives used has changed significantly over this time period. The goal of this project is to assess the feasibility of and generate data using electronic health records on ectopic pregnancy incidence, risk factors, and management trends in the general population and in women using select contraceptive methods, particularly intrauterine devices.
