Although there is both a need and a desire to critically evaluate data
from community-based clinical practices, many clinicians are inadequa
tely prepared for this undertaking. This paper illustrates the process
of establishing a computerized research data base in a community-base
d medical practice by highlighting issues of design, data collection,
enrollment, and data management. In addition, a practical illustration
of implementing such a data base system to perform community-based ou
tcomes research among patients with chronic sinusitis is presented. Da
ta bases established for community-based outcomes research can serve a
s a means for a single medical practice to examine patient outcomes or
can serve as a component of a collaborative multi-site research effor
t.
