Abstract

OBJECTIVES: To provide, from the healthcare delivery system perspective, a cost analysis of the Geriatric Resources for Assessment and Care of Elders (GRACE) intervention, which is effective in improving quality of care and outcomes. DESIGN: Randomized controlled trial with physicians as the unit of randomization. SETTING: Community-based primary care health centers. PARTICIPANTS: Nine hundred fifty-one low-income seniors aged 65 and older; 474 participated in the intervention and 477 in usual care. INTERVENTION: Home-based care management for 2 years by a nurse practitioner and social worker who collaborated with the primary care physician and a geriatrics interdisciplinary team and were guided by 12 care protocols for common geriatric conditions. MEASUREMENTS: Chronic and preventive care costs, acute care costs, and total costs in the full sample (n=951) and predefined high-risk (n=226) and low-risk (n=725) groups. RESULTS: Mean 2-year total costs for intervention patients were not significantly different from those for usual care patients in the full sample ($14,348 vs $11,834; P=.20) and high-risk group ($17,713 vs $18,776; P=.38). In the high-risk group, increases in chronic and preventive care costs were offset by reductions in acute care costs, and the intervention was cost saving during the postintervention, or third, year ($5,088 vs $6,575; P<.001). Mean 2-year total costs were higher in the low-risk group ($13,307 vs $9,654; P=.01). CONCLUSION: In patients at high risk of hospitalization, the GRACE intervention is cost neutral from the healthcare delivery system perspective. A cost-effectiveness analysis is needed to guide decisions about implementation in low-risk patients.
