HealthPartners, a nonprofit managed care organization in Minneapolis, Minn., has developed an integrated system of care for seniors in clinics, hospitals, and subacute care centers. The organization contracts for subacute care with a few skilled nursing facilities distributed throughout the area. Concentration of patients in these facilities allows for the presence of a nurse-practitioner on site. The nurse-practitioner collaborates with a geriatrician to provide care for 15 to 20 seniors. This team uses principles of geriatric assessment to optimize utilization and outcomes for frail seniors.
