MORE DISEASE: HOW MAJOR A FACTOR IN HIGHER UTILIZATION
R03 HS09832-01
09/01/98
Studies have reported large differences in age/sex adjusted rates of hospital
utilization across small areas, often leading to the conclusion that
hospitalization rates in the higher rate areas can be reduced to those in lower
"benchmark" areas. An assumption underlying these recommendations is that age
and sex adjustment has fully accounted for differences in underlying disease in
the different areas. As a proxy for underlying disease, the applicant will use
rates of treatment on an "outpatient" only basis.
The research will study Medicare admissions in 70 small geographic areas of
Massachusetts for 22 medical conditions; 17 of which have been shown in earlier
work by the investigators to be in the top 50% in terms of small area
variation. Rates of outpatient treatment for these 22 conditions will be used
as proxies for prevalence of underlying disease in each of the 70 areas. From
their earlier work they have found the driver of variations in inpatient
admissions are variations in number of individuals admitted (as opposed to
readmissions). Thus, the focus will be on individuals treated in two
categories: as inpatients and outpatients only.
