Background. Even the most uniformly accepted pre-
vention guidelines do not by themselves lead to imple-
mentation or to adequate rates of preventive services
in medical practice. Although much has been learned
about the office systems that seem to be needed for
major change in a busy clinical practice, there are still
no examples of a model for developing, implementing,
and sustaining those office systems in a nonacademic
practice.
Methods. IMPROVE, the first large randomized con-
trolled trial of CQI (continuous quality improvement)
in any industry, is providing a scientific test of the
hypothesis that HMO sponsorship of a CQI-based in-
tervention can lead to sustained organizational
change, implementation and maintenance of office
systems, and improved rates of adult preventive ser-
vices in contracted private primary care clinics. The
22 clinics assigned to the intervention arm of the study
are receiving training, consultation, networking, and
reinforcement for internal multidisciplinary teams as
they work through a structured process to understand
and improve their clinic’s process for providing pre-
ventive services. Rates and quality of eight preventive
services in these clinics are being compared over time
with those in 22 matched comparison clinics.
Results. The 44 clinics needed for the trial have been
recruited and randomized, and baseline comparisons
show no significant differences between the two
groups. Nine months into the trial, 21 of 22 interven-
tion clinics have completed training and are pursuing
a systematic improvement process for preventive ser-
vices.
Conclusions. With external training and consulta-
tion, many private primary care clinics will voluntar-
ily engage in a lengthy multidisciplinary team effort to
use CQI techniques to study and systematically im-
prove their entire process for providing preventive
services. © 1996 Academic Press, Inc.

INTRODUCTION
Both public policymakers and primary care physi-
cians appear to agree that delivery of clinical preven-
tive services is important. Despite that, even most of
those preventive services with widespread support in
the medical community are not currently being pro-
vided at optimal rates, even to patients visiting medi-
cal practices. In fact, most comparisons of physician
attitudes and self-reported preventive behavior
against services reported by patients or recorded in
charts have shown a wide discrepancy between reality
and physician desire/perception.

Why is this? It certainly can no longer be blamed on
the absence of clear guidelines. Healthy People 2000
and the U.S. Preventive Services Task Force have
helped greatly to clarify which services are most im-
portant, what the actual guidelines should be, and the
importance of an evidence basis for guidelines.

How-
ever, even if one focuses on those areas where there is
widespread agreement (e.g., mammography between
the ages of 50 and 75), rates are surprisingly low.

Clearly, guidelines alone are necessary but not suffi-
cient. There is now widespread agreement that the key
issue is how to implement guidelines. We have very
little evidence that anyone has learned how to do this
well.

Lack of reimbursement is not a sufficient excuse ei-
ther, as the Katz and Hofer article comparing preven-
tive services rates between the United States and
Canada demonstrates.

Instead, this deficiency ap-
pears to be primarily due to the realities of medical
practice

clinics are overwhelmingly busy responding to the
problems and requests of their patients.
