Kinder and Gentler: Physicians and Managed Care, 1997-2001
Tracking Report No. 5
November 2002
Bradley C. Strunk, James D. Reschovsky
espite the managed care backlash, an overwhelming majority
of U.S. physicians continue to contract with managed care
health plans. In fact, according to a new Center for Studying
Health System Change (HSC) study, between 1997 and 2001
physicians reported a modest increase in the proportion
of practice revenue from managed care contracts and the
average number of contracts. At the same time, the nature
of physicians relationships with health plans changed, with a
significant decrease in plans use of capitation, or fixed monthly
payments for each patient regardless of the amount of care
provided. Meanwhile, physician practices moved away from
using direct financial incentives to influence doctors clinical
decision making, but did experience an increase in the overall
influence of treatment guidelines and other practices commonly
associated with managed care.
The Rise and Fall of Managed Care?
anaged care plans achieved remarkable success in slowing
health care cost trends in the mid-1990s. The reversal from
high cost growth earlier in the decade was due, in part, to plans
tightly managing access to care through such tools as primary
care physicians (PCPs) acting as gatekeepers to specialists,
requiring hospital admission preauthorizations and limiting
patients choice of doctors and hospitals through narrow
provider networks. But consumers and physicians rebelled
against plans increased oversight and care restrictions.
Despite this backlash, and scattered reports of physicians
opting out of managed care contracts altogether, more than
nine of 10 physicians in 1997 and 2001 owned or were
members of a medical practice that had at least one contract
with a managed care plan (Figure 1). Among physicians
with managed care plan contracts, total average practice
revenue from managed care plans actually increased to 46
percent in 2001, up from 43 percent in 1997 (see Table 1).
Primary care physicians continued to receive a greater share
of total revenue from managed care plans in 2001 than did
specialists (49.7% versus 43.1%).
Moreover, the average number of managed care plan
contracts among physicians with at least one such contract
increased from 12.4 in 1997 to 13.1 in 2001, probably
reflecting plans response to consumer desires for broader
physician networks. This small increase may actually
understate the degree to which managed care plans broadened
their provider networks. There was considerable
consolidation among insurers between 1997 and 2001, and
this would be expected to reduce the average number of
physicians managed care plan contracts.
In recent years, enrollment in preferred provider organizations
(PPOs) has grown substantially at the expense of
health maintenance organization (HMO) enrollment.1
This is likely due to PPOs tendency to place fewer restrictions
on health care service use and allow more direct access to
specialists. Despite this enrollment shift, primary care
physicians in 2001 acted as gatekeepers for 44.6 percent of
their patients, 3.6 percentage points greater than in 1997.
Nearly all of this growth occurred before 1999, however,
when HMO enrollment was still expanding. From 1999
to 2001, the use of primary care physicians acting as
gatekeepers held steady.2

Risk Contracting Declines
lthough managed care plans maintained a strong role in
the practices of most doctors, the nature of physicians relationships with
health plans changed between 1997 and 2001, with a significant decrease in health
plans use of capitation, or fixed per-patient, monthly payments. Also known
as risk contracting, capitation offers strong financial incentives to physicians
to limit the amount of care provided to patients.
Among physicians who owned or were members of a practice with at least one
managed care plan contract, the proportion whose practice derived at least some
revenue from capitation dropped about 9 percentage points to 48.6 percent in
2001 (see Table 2). This trend was evident among both
primary care physicians and specialists, although specialists continued to be
much less likely than primary care physicians to be in a practice receiving
capitated payments—36.4 percent versus 66.7 percent in 2001. Among physicians
whose practice did receive capitated payments, the portion of practice revenue
from capitation remained unchanged between 1997 and 2001 after rising slightly
in 1999.

Use of Financial Incentives
oth health plans and physician practices sometimes tie
specific financial incentives to overall compensation to
influence physicians clinical decision making. These
incentives include profiling—comparing a physicians
pattern of medical resource use with those of other physicians—results of patient satisfaction surveys and quality
of care measures such as rates of preventive care.
Between 1997 and 2001, less than a third of all physicians had their overall
compensation tied to specific financial incentives at the practice level (see
Table 3). Use of profiling tied to physicians compensation declined to
12.2 percent in 2001, from 15.6 percent of physicians in 1997. Primary care
physicians experienced a proportionally greater decline (25%) than did specialists
(19%).
There was no statistically significant change from
1997 to 2001 in the extent to which physicians compensation
was tied to patient satisfaction surveys or quality
measures. Nearly one-quarter (23.6%) of physicians
reported that patient satisfaction survey results were
used in determining their compensation in 2001, and
about 17 percent of physicians reported that specific
measures of quality of care, such as rates of preventive
care services for their patients, were used in determining compensation. Primary care physicians were more likely to
be subject to these types of incentives than were specialists
(29.4% versus 19.8% for patient satisfaction incentives,
and 23.8% versus 13.1% for quality measure incentives).

Impact of Care Management Tools Grows
hile relatively few physicians are subject to explicit
financial incentives, such tools as profiling, patient satisfaction surveys
and treatment guidelines have broader applications for care management. Over
time, the influence of these tools on physicians practice of medicine appears
to be growing, regardless of whether they are tied to compensation. 3
Between 1997 and 2001, the proportion of physicians reporting that feedback
from patient satisfaction surveys had a "very large," "large" or "moderate"
effect on their practice of medicine increased by nearly 4 percentage points
to 61.6 percent (see Table 4). The effect of profiling
increased as well, but only among primary care physicians. In 2001, 40.1 percent
of primary care physicians reported that profiling affected their practice of
medicine, compared with just over 37 percent in 1997. Specialists remained less
likely than primary care physicians to be affected by profiling, with 30.4 percent
affected in 2001.
Treatment guidelines promoted by government and professional medical organizations signal a growing trend toward evidence-based
medicine, and managed care plans often encourage physicians to consider guidelines
in their medical practice. Between 1997 and 2001, the number of conditions for
which treatment guidelines were developed grew, and the percentage of physicians
reporting that treatment guidelines had a "very large,""large" or "moderate"
effect on their practice of medicine increased by more than 10 percentage points
to 56.2 percent. The pro-portion of primary care physicians affected by treatment
guidelines increased 15 percentage points, to 60.7 percent in 2001, while the
percentage of specialists affected by guidelines increased over 7 percentage
points, to 53.2 percent over the same period.

Loosening the Grip
he managed care backlash has altered the relationship
between health plans and physicians—not toward less managed care, but,
rather, to a kinder, gentler managed care. Managed cares loosened grip on physicians
is likely a contributing factor to a return to double-digit health care spending
increases in 2001.4 To the extent health plans are
introducing new ways to influence physicians clinical decision making today,
there are signs that the focus is on quality, i.e., rewarding physicians who
meet certain care standards. An example is the Pay for Performance initiative
launched recently by six California insurers where physicians receive additional
payments for meeting quality measures.
Unlike the 1990s, when health plans cost-containment
efforts focused on lower provider payments and influencing
physician behavior, the emphasis today appears to be on
influencing patient behavior through greater cost sharing in
the form of deductibles, coinsurance and copayments.
Continued cost pressures, the limits of a patient-focused
approach and the possibility of a backlash from patients,
however, may bring the spotlight back to ways to influence
physicians medical decisions.
Data Sources
his Tracking Report presents findings from the HSC Community
Tracking Study Physician Survey, a nationally representative telephone survey
of physicians involved in direct patient care in the continental United States
conduct-ed in 1996-97, 1998-99 and 2000-01. For discussion and presentation,
we refer to a single calendar year of the survey (1997, 1999 and 2001). The
sample of physicians was drawn from the American Medical Association and the
American Osteopathic Association master files and included active, nonfederal,
office- and hospital-based physicians who spent at least 20 hours a week in
direct patient care. Residents and fellows were excluded. Each round of the
survey contains information on approximately 12,000 physicians, and the response
rate ranged from 60 percent to 65 percent.

Although trends are similar, physicians for whom profiling or patient
satisfaction surveys are tied to compensation are substantially more likely
to report that these tools have a "moderate" to "very large" effect on their
practice of medicine than are physicians for whom these tools are not linked
to compensation. |
