Abstract

A range of NCD is prevalent in both community and LTC settings, with the highest rates observed among the oldest-old. To improve functional independence, community primary healthcare should prioritise early cardiovascular disease management, physical health maintenance, correction of sensory impairments, and promotion of intellectual and social engagement. For effective healthcare planning for frail older adults living in LTC, the complex needs of nursing home residents with NCD should be addressed.
