The objective was to determine the relationship between a high score on the ERA index and 2-year mortality and nursing home placement. As of January 1, 2005, 12,650 community-dwelling patients over 60 years of age were impaneled with a primary care practice at the Mayo Clinic in Rochester, MN. This was a retrospective cohort study utilizing an administrative risk score, the ERA score. Primary outcomes were 2-year mortality and 2-year nursing home placement. The predictor variable was ERA score. Relative risk estimates were used to describe the association between the ERA index and mortality and nursing home placement. The relative risk of 2-year mortality was 51.4 (95% confidence interval=CI=28.0-94.4) in patients in the highest risk group compared to the lowest group. The relative risk of nursing home placement was 113.2 (95% CI=76.1-168.4). Patients with high ERA scores are at high risk for 2-year mortality and 2-year nursing home placement. These findings suggest that the utilization of an electronic risk score can help identify patients at risk for death or nursing home placement. Clinically, the identification of high risk individuals may be useful for utilization of clinical case management.
