The Palo Alto Medical Foundation designed and implemented a novel team-based chronic care model (“Champion”) to support patients’ self-management of hypertension and diabetes. Components of the model include proactive patient outreach, depression screening, and health coaching. This quasi-experimental study comparing the Champion clinic-level intervention with a usual care clinic measured blood pressure and glycohemoglobin in the two years prior and one year post implementation. Findings show that Champion standard work improved glycemic control over the first 6 months and physicians’ experience with managing chronic care, but changes in blood pressure were not clinically meaningful.
