Edward H. Wagner, MD, MPH, Director, The W.A. MacColl Institute for Healthcare Innovation, Group Health Cooperative of Puget Sound, Seattle, Washington, is recognized internationally for his development of the Chronic Care Model, which encourages high-quality chronic disease management. Recognizing Dr. Wagner's work on developing and evaluating interventions for people with chronic illnesses, the Foundation awarded Group Health Cooperative of Puget Sound a five-year grant of $1,523,571 to develop the Senior Resource Team model of team care.
Foundations can offer funding to test creative solutions with the understanding that not all projects will produce viable interventions. In the case of the Senior Resource Team, when the intervention was tested it did not result in better patient outcomes than the control group. Therefore, this model was not included in the dissemination of the GIT-P grant.
Most older adults receive health care from primary care physicians who are not specialists in geriatrics. In the United States, there are on average 5.5 geriatricians per 10,000 persons aged 7526 and the fill rate for the first year of geriatric medicine fellowship training programs is only about 70 percent.27 This means that generalists working in primary care settings provide health care for large numbers of older patients, yet they often lack adequate training in the care of this population of patients. The result is the potential for suboptimal quality of care for older adults, who are at greatest risk for complex health problems and functional decline.
Edward H. Wagner, MD, MPH, and his colleagues at Group Health Cooperative of Puget Sound sought to address this issue by creating the Senior Resource Team model, in which an interdisciplinary geriatric consulting team is embedded in a primary care practice. In this model, the geriatric team consisted of a geriatrician, a gerontological nurse practitioner, and a pharmacist with specialized geriatric training (offsite but connected electronically). Dr. Wagner and his team reasoned that the close proximity of clinicians with geriatric expertise would encourage formal referrals as well as informal consultation, which would improve quality of care.
The Senior Resource Team provided ongoing geriatric education and
support and focused on assessment and management of older adult
outpatients (age 75 and older) at risk for disability, geriatric
syndromes, and control of chronic diseases. The developers of the
model hypothesized that this team approach would result in less
functional decline and fewer hospitalizations for older patients.
“We're contributing to the growing body of evidence that if you really
want to improve important health measures in older patients you have
to have a team with geriatric expertise actually manage the patients
for a period of time, similar to the GEM units.”

To test this hypothesis, the team at Group Health Cooperative
conducted a study involving two clinics and a total of 31 primary care
providers. Patients aged 75 and older were randomly selected to
receive care either with or without the Senior Resource Team model.
After two years of the study, Dr. Wagner and his colleagues were
not able to demonstrate a measurable benefit with the model. Overall,
the primary care physicians viewed the intervention favorably and felt
that their patients benefited from the direct care of the geriatric
team and from the team's indirect influence on the primary care
physician. However, referrals to the geriatric team were limited and
there was no improvement in patients' functional ability, which was
the main objective of the study.
“Even though the geriatric team was just down the hall, the kind of formal consultation that we had in mind didn't happen very often,” says Dr. Wagner. There was a subset of patients who were referred to the geriatric team, but these patients did no better than the control group. As a possible explanation, Dr. Wagner suggests that the geriatric teams in the Senior Resource Team model took a less intensive approach than a geriatric evaluation and management (GEM) unit, which has been shown to benefit patients. In a GEM unit, the geriatric team takes over care of the patient for a period of time. “Our teams didn't take over the care of patients,” says Dr. Wagner. “They complemented the primary care of patients and they tried to influence the primary care.”
Because the Senior Resource Team model was not able to demonstrate
improvement in care of older adult patients, it has not been included
in the GIT-P dissemination initiative. From the outset, the Foundation
did not anticipate the success of all of the models. An important role
of foundations is to take risks on untested interventions with the
goal of learning from experience and thereby enhancing delivery of
care to older adults. Even though the Senior Resource Team model did
not produce the hoped for measurable improvements in patient outcomes,
it did provide these important lessons.
