Aetna said it has been successfully improving care and cutting medical costs because of its accountable care program that embeds nurse case managers in doctor offices, the Hartford Courant reported. More than 50,000 of Aetna's Medicare Advantage members receive care from about 70 doctor offices and clinics, each of which has a nurse manager working directly with the providers. Aetna's accountable care program with NovaHealth, a doctor group in Portland, Maine, led to a 50 percent reduction in inpatient hospital days, a 45 percent drop in hospital admissions and 56 percent fewer readmissions than other Medicare recipients in the state.
