This book conveys the good news: there is considerable evidence that practitioners themselves can design more effective systems of care for older people, often at lower costs. The researchers here point the way ahead: "evidence-based" interventions; proactive population-based care programs; patient-centered delivery models--all developed under rigorous research controls and under the mandates of managed care. The results reported here are proof that the convergence of wellness movements, patient participation, and managed care administration can be harnessed for improved and often more cost-effective gerontologic care.
