More May Be Better: Evidence of a Negative Relationship Between Physician Supply and Hospitalization for Ambulatory Care Sensitive Conditions
Health Services Research, 40(4):1148-1166.
The authors conducted an empirical test of the
relationship between physician supply and hospitalization
for ambulatory care sensitive conditions (ACSH).
Principal findings showed that in the urban models for
ages 0-17 physician supply has the largest negative
adjusted relationship with ACSH. For ages 18-39 and
40-64, physician supply has the second largest negative
adjusted relationship with ACSH. Physician supply was not
associated with ACSH in rural areas. The authors conclude
that physician supply is positively associated with the
overall performance of the primary health care system in
a large sample of urban counties of the United States.
