It¿s a core issue at the heart of elder care: while best-practice data exist for long-term care, quality of life as a concept, measure and standard for care outcomes remains elusive. The result of an ambitious European research initiative, the Care Keys Project addresses quality of life issues among frail, care-dependent seniors, taking their social as well as health needs into account. This resulting volume explains the theory behind Care Keys, its methodology, empirical findings, and practical considerations in promoting effective, efficient elder care aimed at social and emotional well-being and including disabled and cognitively impaired patients.
