Epidemiologic, Population, and Health Outcome Studies
Since the late 1990’s, the CDC Epilepsy Program has promoted epidemiologic and related research by means of in-house data collection and analysis, funding and technical assistance to academic investigators, and collaborations with other programs within CDC and within the US Department of Health and Human Services. The following is a description of currently funded academic research projects, followed by a list of selected peer-reviewed publications describing the findings of previously supported research and surveillance projects.
Current Studies (2013)
The Incidence and Prognosis of Epilepsy in Harlem, New York City
Columbia University, New York, New York
Principal Investigator: Dale C. Hesdorffer, PhD
The purpose of this project, funded through the Prevention Research Centers, is to assess early factors that affect outcomes in a 2 year follow-up study of new-onset cases of epilepsy in the population of Harlem and Northern Manhattan, New York City. This is a prospective incidence cohort study in which newly diagnosed cases of epilepsy and unprovoked seizures will be ascertained through active surveillance of area hospitals and emergency departments. Cases will be followed for a minimum of 2 years. Potential prognostic factors will include age, seizure characteristics, socioeconomic status, burden of comorbidity, access to specialty care, and lifetime history of depression and anxiety. Outcomes will include seizure recurrence and mortality.
This study received initial CDC funding in autumn 2009.
Epidemiologic Follow-up Study of Newly Diagnosed Epilepsy Among the Elderly
University of Arizona, Tucson, Arizona
Principal and Co-Investigators: David Labiner, MD and Jenny Chong, PhD
This study, funded through the Prevention Research Centers, is analyzing quantitative, administrative, and qualitative data to - (1) describe the public health burden of epilepsy in people in southeastern Arizona aged 65 years or older with new onset seizures, and (2) identify early factors that affect clinical outcomes and health care in this population. The effects of ethnicity and socioeconomic status will also be assessed. The study is designed as a prospective cohort study, including both incident and prevalent cases. Newly diagnosed cases of epilepsy will be ascertained in this population from multiple health care sources serving southeastern Arizona, including the Arizona Neurological Emergency Treatment Trials network (AzNETT), a regional neurology specialty group, Medicare Data, geriatric clinics and senior service providers, and others. People will be followed for 2 years or more, with follow-up interviews to assess outcomes.
This study received initial CDC funding in fall 2010.
Risk Factors of Epilepsy Outcomes: Comorbidities in Populations with Epilepsy
Medical University of South Carolina (MUSC), Charleston, South Carolina
Principal Investigator: Anbesaw W. Selassie, DrPH
The goal of this study is to examine the prevalence and patterns of common coexisting (comorbid) conditions among people with epilepsy, as well as the relation of these comorbidities with epilepsy outcomes, health care use and cost, and mortality. The study is designed with two phases: (1) a statewide prevalence study of comorbid conditions among people with epilepsy, and (2) a retrospective cohort study of a sample of people with epilepsy compared to a sample with selected other conditions. Cases will be found and data collected from linked datasets maintained by the South Carolina Office of Research and Statistics (ORS), encompassing visits across the spectrum of health care provider sites. Additional data in Phase 2 will be abstracted and collected from the MUSC’s Comprehensive Epilepsy Center and from other medical records, with informed consent of the subjects.
This study received initial CDC funding in autumn 2011.
Epidemiologic Research and Surveillance in Pediatric Epilepsy
RTI International, Washington, District of Columbia
Principal Investigator: Barbara Kroner, PhD
The purpose of this study is: (a) to describe the incidence and prevalence of epilepsy among children (aged 1 month to 18 years) in a racially and economically diverse population (District of Columbia); (b) to assess use of healthcare, responsiveness of health systems, and obstacles to care among children with epilepsy and their families; and (c) to characterize risk factors, outcomes and coexisting health conditions (comorbidities) related to prevalent and new-onset pediatric epilepsy. This is a prospective cohort study. Cases will be ascertained from the Children’s National Medical Center (CNMC) and Howard University Hospital, which together provide the majority of care for children with epilepsy in the District of Columbia. Data will be collected by abstracting medical records, as well as follow-up interview surveys. The period of follow-up is projected to be 2-3 years.
This study received initial CDC funding in autumn 2011.
