Objective: To evaluate whether there is an association between county-level obstetrician-gynecologist (ob-gyn) and primary care physician (PCP) densities and gynecologic cancer outcomes in the United States.

Methods: A retrospective cohort study of gynecologic cancers (uterine, ovarian, and cervical) in the Surveillance, Epidemiology, and End Results (SEER) database was performed from 2005 to 2018. County-level demographics were abstracted from the SEER database, population density from the United States Census Bureau, and physician density (ob-gyns and PCPs/100,000 females) from the Area Health Resources File.

Objective: The purpose of this study was to evaluate the ability of motion tracking to discern variation in forceps paths during standardized simulated forceps-assisted vaginal deliveries among experienced and inexperienced obstetric providers.

Methods: This is a pilot study involving 24 obstetrics and gynecology residents and 6 faculty at a single institution. Each participant was filmed performing standardized simulated forceps-assisted vaginal deliveries on a high-fidelity model.

Objective: To estimate the impact on stillbirth risk, cesarean deliveries, and delivery-related healthcare cost associated with induction of labor compared to expectant management of term pregnancies in an obese population.

Methods: A decision analysis model was designed to compare the delivery and cost outcomes associated with a hypothetical cohort of 100,000 term pregnancies, complicated by obesity, that were planning a vaginal delivery. The model predicted stillbirths, cesarean deliveries, and total delivery-related health care cost from routine induction at 39 weeks compared to expectant management and routine induction each week from 40 to 42 weeks.

Objective: To identify independent risk factors for cesarean delivery after induction of labor and to develop a nomogram for predicting cesarean delivery among nulliparous women undergoing induction of labor at term.

Methods: This is a retrospective cohort study including nulliparous women with singleton, term (37 0/7 weeks of gestation or greater), cephalic pregnancies undergoing induction of labor from July 1, 2006, through May 31, 2012, at a tertiary care academic center. Inductions were identified using International Classification of Diseases, 9th Revision codes.

Objective: We used receiver operating characteristic (ROC) analysis to compare two methods of evaluating observer performance in detecting an abnormality on chest radiographs. In the first method, the abnormality in question, rib fracture, was one of five investigated, and it was the only one of interest in the second.

Materials And Methods: Eight experienced observers viewed 117 posteroanterior chest radiographs in two interpretation modes.
