As the longevity and population of older persons increase in many nations, a central question is whether this population aging will be accompanied by sustained or improved health, an improving quality of life, and sufficient social and economic resources. As such, this study aimed at determining an elderly care system that will bridge the gap between the rising needs of the Filipino elderly and the current systems and practices in the delivery of services to the aging population at the basic level – the family and at the institutional level – with local and national government agencies. The study developed a susceptibility index with indicator levels that would correspond to varying categories of elderly care needs determined by universal care policies, family demographics, health risks, and environments of specific target populations, the significance of the factors of which were statistically established from interview and survey results gathered from a representative metropolitan city. Additionally, the study included the bases for the development of a system application in the formulation of effective policies aimed at enhancing the health status, as well as the social and economic well-being, of elderly Filipinos. This model can be emulated at the provincial and regional levels in the country.
