# POPULATION-BASED STUDY OF U S HIP FRACTURES

> **NIH NIH R01** · MEDICAL COLLEGE OF WISCONSIN · 1990 · $62,735

## Abstract

The purpose of this proposed study is twofold.  First, this study
will provide population based estimates of the incidence of
fractures of the hip among the elderly population of the United
States, aged 65 years and older.  Second, this study will
estimate case-fatality rates for those persons having suffered a
fracture of the hip.  To this end, discharge data from all short
stay hospitals from 1984 to 1987, obtained from the Health Care
Financing Administration (HCFA) and the Veterans Administration,
will be used to provide estimates of the frequency of fracture of
the hip and all-cause mortality subsequent to the injury in this
population.  Combining these data with the county-, age-, race-,
and sex-specific estimates of the United States population for
1985 from the Bureau of the Census, this study will provide very
precise estimates of the incidence of, and subsequent mortality
association with fracture of the hip.

These estimates will be unique; for the first time in this
country they will be based on an enumeration of all hip fractures
occurring among the elderly in All regions of the country.
Further, estimates will include age-specific rates of the old,
above 85 years of age.  With these, detailed maps of the
incidence of hip fracture will be developed and combined into an
atlas depicting the geographic variation in incidence across the
country.  Further, seasonal variation will be assessed through
the detailed examination of dates of admission for 1984 to 1987.
Thus, the estimates of incidence and survival will provide:  1)
an extremely detailed picture of the epidemiology of the
incidence of fracture of the hip, and 2) a detailed description
of the all-cause mortality experience of elderly persons
suffering a fracture of the hip.  Such estimates will enable
health care planners to accurately and precisely assess the
burden that this common injury places on our society.  In
addition, the description of the variation in person, place, and
time may aid researchers in developing new hypotheses for the
etiology of hip fractures.
