Financing long-term care; Long-term care cost; Long-term care fund Definition Long-term care (LTC) financing refers to the collection, management, and distribution of funds by legal approaches (private insurances, co-payments, taxes, social insurances, etc.) to support the LTC insurance and services for older adults who may require assistance with daily living activities (Stone 2000; Ranci and Pavolini 2013; European Commission 2015) and to ensure the quality and appropriateness of LTC services (Organisation for Economic Cooperation and Development (OECD)/European Commission 2013; Feng 2019).
