A la luz de lo expuesto parece que otros componentes, diferentes de la edad por sí misma, son los que explican en mayor proporción el coste sanitario y no sanitario en poblaciones de edad más avanzada, siendo fundamentalmente el estado funcional (como son la fragilidad, discapacidad y dependencia) el principal factor incremental del mismo. Esta conclusión abre, por tanto, una nueva agenda de investigación que profundice en el análisis de la relación entre distintos síndromes asociados con el deterioro funcional y el gasto sanitario y no sanitario, así como en el análisis y evaluación de distintas intervenciones que sirvan no solo para mejorar el bienestar y la salud individual, sino que supongan ahorros en términos monetarios. Ello es necesario para conciliar el doble objetivo de perseguir que las personas mayores vivan más y mejor, gestionando al tiempo los recursos disponibles con criterios de eficiencia y equidad, como garantía de avance en la solvencia de los sistemas de cuidados de la salud.
