The Clinical Outcomes Research Office of the Division of Research performs basic
and applied clinical epidemiology and health services research. Clinical epidemiology
is the study of the diagnosis, prognosis, and evaluation of treatment. The scientific
methodology of clinical epidemiology is based on the architecture of clinical research,
biostatistics, and data processing. Part of this methodology is borrowed from public health
epidemiology and is applied to the uniquely clinical situations that clinicians face.
Clinical epidemiology, therefore, is a methodology that can be applied to the study of
any and all human disease and illness. Health services research can be defined as efforts
to determine how the health system functions so that its performance can be improved. This
definition makes the field essentially activist in nature.
