Attempting vaginal birth after cesarean section (VBAC) places women at an increased risk for complications. We set out to identify factors that are predictive of major morbidity in women who attempt VBAC. A nested case-control study was performed within a large retrospective cohort study of women with a history of at least one cesarean. Women who attempted(More)
OBJECTIVE Occupational use of vibrating hand tools contributes to the development of upper extremity disorders. While several types of vibration damping materials are commercially available, reductions in vibration exposure are usually tested in the laboratory rather than in actual work environments. This study evaluated reductions in hand vibration with(More)

OBJECTIVE Standardized oxytocin protocols have been used to improve the safety and quality of obstetric care. We examined rates of chorioamnionitis and labor dystocia requiring cesarean delivery as unintended consequences of the implementation of a low-dose, checklist-based oxytocin protocol. STUDY DESIGN We performed a retrospective cohort study of live(More)
Ergonomic studies often use worker estimated hand force reproduced on a dynamometer to quantify force exposures but this method has not been well-studied in real work settings. This study evaluated the validity of worker estimates of hand force in a field study and determined the misclassification of worker estimated hand force exposures compared to(More)
