# ROCHESTER EPIDEMIOLOGY PROJECT

> **NIH NIH R01** · MAYO CLINIC ROCHESTER · 1992 · $305,737

## Abstract

The Rochester Epidemiology Project (REP) is a unique, population-based
data resource comprised of the complete (impatient and outpatient)
medical records of all Olmsted County, MN residents for the entire
duration of their residency in the County.  Our data base now covers the
medical care delivered by essentially all providers to County residents
from 1909 through the present and has resulted in 565 publications since
the system was organized in 1966 (and 212 since the last competitive
renewal five years ago) on a myriad of topics--many relating to critical
health issues of national importance.  The REP supports the work of a
large number of investigators from Mayo and other academic institutions
in the United States and abroad and makes possible the efficient conduct
of extramurally funded studies of coronary heart disease, stroke,
dementia and other neurological conditions, cancer, diabetes and other
metabolic diseases, gastrointestinal disorders, osteoporosis, arthritis,
and other.  Although Mayo Clinic contributes substantially by indexing
the diagnoses, surgical procedures and pathology recorded in its own
records at no cost to this project, it is the responsibility of the REP
to collect the diagnostic data from non-Mayo providers, to integrate the
information from all sources of care, and to make it accessible to all
qualified investigators for descriptive and analytic studies.  Continued
support is needed to supplement the Mayo Clinic diagnostic index with
data from the Olmsted Medical Group, the Olmsted Community Hospital and
several other non-Mayo sources of medical care in and around Olmsted
County and to undertake organizational tasks that enhance the research
capabilities of the Rochester Epidemiology Project and increase its
efficiency.

The funds requested are required to (1) maintain and continue adding to
the non-Mayo portion of the REP data base, which makes possible the full
level of case ascertainment and follow-up required for population-based
studies in Rochester and Olmsted County and forms the essential core for
epidemiologic research in this population; (2) extend our research
capabilities by forming new indexes for laboratory results, diagnostic
procedures and medications; (3) modernize the data base by using
relational data base technology to develop a global file (the REP
Medical Profile) containing a longitudinal record of names,
identification numbers, residences, episodes of medical care and
hospitalization, clinical and pathological diagnoses, surgical and
diagnostic procedures, laboratory values, prescription drugs, and
linkages to the detailed data of each resident enrolled in a specific
study or registry; and (4) enhance the efficiency of logistical support
by automating many of the procedures for sample selection, for residency
verification, and for generating and tracking follow-up correspondence,
and by establishing an interface with the National Death Index.
