Betty R. Vohr, MD "The Investigation of the Neurodevelopmental,Language, Behavioral, and Growth Status of High Risk Populations of Infants" Our research interests are focused on clinical longitudinal studies of high risk populations. The Neonatal Follow-up Program provides longitudinal assessments and management of high risk extremely low birth weight and moderately low birth weight infants. We are the Coordinating Center for NICHD NRN studies of neurologic and developmental outcome. A second area of investigation is the identification and outcome of infants with hearing impairment. We are investigating language and behavior outcomes of children with hearing loss. A third are of investigation is the provision of enhanced transition home services to decrease ER visits, rehospitalizations and health care costs. A fourth area is healthcare disparities and effects of high risk neighborhoods.
