Unprecedented
attention is being placed on cardiovascular disease
prevention. This
focus on prevention has arisen for four major reasons in the
United States. These
reasons are: escalating health care costs, publication of
landmark clinical trials documenting the effectiveness of
cardiovascular disease risk management interventions,
implementation of quality assurance measures, and assumption
of financial risk by physicians and hospitals for the health
care of patients enrolled in capitated managed care plans.
It is
widely believed that future health care systems will be
built on “pillars of prevention.”
However, although sound clinical reasons exist for
emphasizing prevention in day-to-day medical practice,
studies indicate that physicians often fail to provide
recommended cardiovascular disease risk management
interventions. Recent
evidence has identified a large gap between recommended
preventive therapies for persons with or at risk for
cardiovascular disease and the care they are actually
receiving. This
“treatment gap” remains a final frustrating impediment
to fulfilling the potential for improving quality of life
and prognosis through cardiovascular disease risk management
interventions.
Clearly,
there is an urgent need to bridge the treatment gap by
developing and implementing approaches that provide all
persons with or at risk for preventable forms of
cardiovascular disease (especially atherosclerotic vascular
disease) access to high-quality, cost-effective, long-term,
comprehensive risk management services appropriate for their
specific needs and personal circumstances.
It is recommended that these approaches be based on
models shown to be effective in appropriately designed
clinical trials. In this manuscript, I briefly describe the key features of
two such approaches we have successfully implemented in
clinical and community-based settings.
Risk Management in Patients with
Established
Atherosclerotic Cardiovascular Disease
(Secondary Prevention)
Recent
arteriographic, secondary prevention clinical trials have
convincingly demonstrated the efficacy of aggressive
cardiovascular disease risk factor modification.
Of the various studies performed to date, the
Stanford Coronary Risk Intervention Project (SCRIP) is of
particular relevance because it utilized what appears to be
the most logical approach to risk management, namely,
aggressive modification of multiple cardiovascular disease
risk factors via comprehensive lifestyle intervention
combined with appropriate pharmacotherapy.
Moreover, SCRIP employed a physician-supervised,
nurse case manager model with consultation from other health
care professionals that could be potentially implemented in
a variety of settings.
In SCRIP, the multifactor risk management program
reduced hospitalization for clinical cardiac events by 40%
(p<0.05) versus usual care during the 4-year study
period.
To
determine the feasibility of implementing a comprehensive
cardiovascular disease risk management program modeled after
SCRIP outside of an academic research setting, we modified
SCRIP protocols for use by a private practice cardiology
group in collaboration with a hospital-based outpatient
cardiac rehabilitation program in Dallas, Texas. Based on our experiences with 367 consecutive patients
enrolled in the risk management program in Dallas between
November 1993 and February 1995, together with newer
guidelines from authoritative organizations, the protocols
were further revised. In
mid-August 1995, we implemented the risk management program
in collaboration with a hospital-based outpatient cardiac
rehabilitation program in Savannah, Georgia.
During the initial 20 months, 1016 new patients with
or at high risk for atherosclerotic cardiovascular disease
were enrolled in the program.
The basic
approach to comprehensive cardiovascular disease risk
management currently utilized at our center in Savannah for
patients with established aterosclerotic cardiovascular
disease is summarized in Figure
1. The
cardiovascular disease risk management action plan focuses
on the interventions listed in Table
1, in accordance with published American Heart
Association and American College of Cardiology guidelines.
Key components of the action plan are summarized in Table 2.
Our
experiences to date in Dallas and Savannah clearly indicate
that a comprehensive risk management program for patients
with atherosclerotic cardiovascular disease modeled after
the protocols used in SCRIP can be implemented in a private
practice/hospital outpatient cardiac rehabilitation setting.
Significant challenges to the successful
implementation of such a program include: 1) the program may
be perceived as “competition” by potential referring
physicians; 2) the program may not be regarded as a high
priority by potential referring physicians; 3) the need to
coordinate program services with those provided by referring
physicians to prevent unnecessary duplication of services;
and 4) the need to implement approaches that are financially
viable in a fee-for-service environment but at the same time
cost-effective and appropriate for use in a managed care
environment.
