Originate
in the phenomenon of practice pattern variations described
|
|
|
by
Wennberg and his associates in a continuing series of studies
|
|
|
starting
in the mid 70’s
|
|
|
|
– |
These
papers demonstrated substantial geographical variation in
|
|
|
the
aggregate use of physician and hospital services
|
|
|
|
– |
And
in specific utilization rates of common surgical and radiologic
|
|
procedures
|
|
|
|
– |
The
authors argued that these variations neither reflect an intrinsic
|
|
|
variation
in the prevalence of specific conditions, nor are
|
|
|
explained
by differing patient preferences,
|
|
| n |
What
they do represent is still a matter of considerable debate
|
|
|
| n |
Nevertheless
appears to be general agreement that such variations are
|
|
|
a
symptom of something seriously wrong with our health system
|
|
|
|
– |
Which
should either be addressed for its own sake or as a way of
|
|
|
controlling
health care costs
