Background: Strategies to control medical costs and improve the quality of
care often translate into decisions affecting the range of services primary
care physicians provide to patients, which patients are referred for speci
alty care, and the points in disease processes at which referrals are made.
This study focused on physicians' assessments of changes in the scope of c
are provided by primary care physicians and their assessments of the approp
riateness of the scope of the care that primary care physicians are expecte
d to provide.
Methods: We analyzed data from the 1996-1997 Community Tracking Study Physi
cian Survey. Telephone interviews were conducted with 12,385 physicians (re
flecting a response rate of 65 percent) who were drawn from a representativ
e random sample of physicians providing direct patient care in the continen
tal United States and not employed by the federal government. The analysis
was based on responses from the 7015 primary care physicians and 5092 speci
alists who had been in practice for at least two years.
Results: Thirty percent of the primary care physicians and 50 percent of th
e specialists reported that the scope of care provided by primary care phys
icians had increased during the previous two years. Twenty-four percent of
the primary care physicians and 38 percent of the specialists reported that
the scope of care expected to be provided by primary care physicians was g
reater than it should be. According to multivariate analysis, primary care
physicians other than general or family practitioners (i.e., pediatricians
and general internists), those who were in one- or two-physician practices,
those who received revenues from capitation, and those who served as gatek
eepers for their patients' care were significantly more likely to report th
at the scope of care they were expected to provide was greater than it shou
ld be.
Conclusions: The finding that nearly one in four primary care physicians re
ported that the scope of care they were expected to provide was greater tha
n it should be arouses concern about the potential impact of changes in the
delivery of health care. The associations we found between financial and a
dministrative aspects of managed care and physicians' concern about the sco
pe of care they provide to their patients deserve careful consideration. (N
