BackgroundTeam care can improve management of chronic conditions, but implementing a team approach in an academic primary care clinic presents unique challenges.ObjectivesTo implement and evaluate the Teamlet Model, which uses health coaches working with primary care physicians to improve care for patients with diabetes and/or hypertension in an academic practice.DesignProcess and outcome measures were compared before and during the intervention in patients seen with the Teamlet Model and in a comparison patient group.ParticipantsFirst year family medicine residents, medical assistants, health workers, and adult patients with either type 2 diabetes or hypertension in a large public health clinic.InterventionHealth coaches, in coordination with resident primary care physicians, met with patients before and after clinic visits and called patients between visits.MeasurementsMeasurement of body mass index, assessment of smoking status, and formulation of a self-management plan prior to and during the intervention period for patients in the Teamlet Model group. Testing for LDL and HbA1C and the proportion of patients at goal for blood pressure, LDL, and HbA1C in the Teamlet Model and comparison groups in the year prior to and during implementation.ResultsTeamlet patients showed improvement in all measures, though improvement was significant only for smoking, BMI, and self-management plan documentation and testing for LDL (p = 0.02), with a trend towards significance for LDL at goal (p = 0.07). Teamlet patients showed a greater, but non-significant, increase in the proportion of patients tested for HbA1C and proportion reaching goal for blood pressure, HgbA1C, and LDL compared to the comparison group patients. The difference for blood pressure was marginally significant (p = 0.06). In contrast, patients in the comparison group were significantly more likely to have had testing for LDL (P = 0.001).ConclusionsThe Teamlet Model may improve chronic care in academic primary care practices.
