What are Research Studies? (Empirical Research)

USM Basics of Research Literature

Research studies can be defined as information or knowledge derived from a scientific investigation of a topic. Research studies are often referred to as "empirical" studies because they utilize objective experience and/or observation to gather data, the definition of empirical. Research or empirical studies are most often published in scholarly peer-reviewed journals and the articles typically follow a format and methodology outlined by the publisher or the academic discipline (shown in the example below):

Margaret, A.K., et al."Evaluating the Epidemiology of Inflicted Traumatic Brain Injury in Infants of U.S. Military Families." American Journal of Preventive Medicine Volume 34, Issue 4, Supplement 1, April 2008, Pages S143-S147

Background
Evaluating the incidence of inflicted traumatic brain injuries (inflicted TBI) in young children, and encompassing shaken baby syndrome (SBS) and related injuries, is an epidemiologic challenge. Data available regarding military families in the U.S. may complement other national surveillance efforts.

Methods
A protocol was developed to assess the epidemiology of inflicted TBI among infants of U.S. military families, integrating data from the Department of Defense Birth and Infant Health Registry, healthcare utilization databases, child abuse reporting systems, and military personnel databases. The in-progress protocol, and its inherent strengths and limitations, are described here.

Discussion
The primary strengths of data from U.S. military families are related to the full characterization of the denominator, such that analyses are person-time and population based. Unique data are available to describe the full population of military parents, including occupational, geographic, and socioeconomic factors, as well as deployment-related potential stressors. The limitations of military data are similar to many other child abuse surveillance systems in that cases are underreported and not fully characterized. Linking abuse reports and medical utilization data to population data, however, will allow unique analyses of "probable" and "possible" cases of inflicted TBI in infants of military families.

Conclusions
Data from the U.S. military, when appropriately linked and analyzed, provide opportunities to evaluate important risk factors for inflicted TBI in infants. Although epidemiologic challenges may make incidence rates using military data noncomparable to rates using other data sources, multivariate analyses can evaluate critical and unique risk factors, as well as the effectiveness of prevention initiatives.
