This publication presents findings of a study on the availability and provision of long-term care (LTC) in Tonga. It discusses the need for and supply of LTC in the country, including regulatory and policy frameworks, service provision, quality management, human resources, and financing. Analysis, conclusions, and recommendations for the development of LTC systems in Tonga are also included. Aiming to contribute to increasing the knowledge base on LTC policies, programs, and systems, this publication is one of six country diagnostic studies—the others on Indonesia, Mongolia, Sri Lanka, Thailand, and Viet Nam—prepared under the Asian Development Bank technical assistance 9111: Strengthening Developing Member Countries' Capacity in Elderly Care.
