Biostatistics and Epidemiology
Westat optimizes clients’ clinical trials and observational and disease surveillance studies to rapidly generate the intelligence needed to safeguard and improve the nation’s health. Our researchers answer concerns about vaccine effectiveness and diseases.
Overview
Westat is at the forefront of health research, and our biostatisticians and epidemiologists bring innovative approaches to address a wide range of clinical trial, observational, and surveillance studies. Our clients rely on us for expert methodology, innovative infrastructure, experienced coordination, and actionable results. Our research pushes the boundaries of public health knowledge, investigating important issues such as the household transmission rates of COVID-19 and the comparative effectiveness of Food and Drug Administration (FDA)-approved influenza vaccines.
Our Expertise
Biostatistical Methods
Driven to improve health, Westat biostatisticians expertly apply appropriate methods to address a wide array of scientific questions in both observational and clinical science. Our analyses include anywhere from a handful of patients in a clinical setting to millions in an electronic health record (EHR) system, sometimes each with hundreds of data points. When an existing method does not meet the needs of a study or the implications of an analytic choice are unclear, we develop and test new methods in collaboration with our clients.
Epidemiologic Studies
Westat’s epidemiologists have supported critical epidemiological research studies, utilizing various study methods and designs to assess data retrospectively and prospectively. Westat has developed and utilized innovative tools and methods to provide clients with research services that support epidemiologic studies related to both communicable and non-communicable diseases. Westat’s epidemiologic studies have supported research that has direct policy implications such as collaborating to produce the White House Reports on Long COVID, information about household transmission of SARS-CoV-2, and COVID-19 vaccine effectiveness estimates.
Disease Surveillance
Westat is committed to using our expertise in epidemiology, statistics, and public health to strengthen disease surveillance. Our efforts to monitor trends, identify sentinel events, and track key metrics provide decisionmakers with critical situational awareness. Partnering with federal and state agencies in fields ranging from infectious disease to substance abuse, we apply rigorous methodology to both traditional and innovative data collection and analysis, generating timely insights to support public health action.
