Social workers yesterday urged the Government to merge the Hospital Authority and the Health Department to provide improved primary care. The Hong Kong Council of Social Service suggested the new body, which would provide both primary and secondary health care, be called the Medical Services Authority. The merger would avoid duplication of resources and achieve better co-ordination in providing primary care, the council said as it voiced its opinions on the Harvard report yesterday. However, Fung Ho-lup, associate professor of social work at the Chinese University, claimed the current health system was the fairest. In the council's two-year study, 40 per cent of respondents said they were happy with the present health system, and 30 per cent supported the idea of a centralised medical insurance scheme as suggested by the report. Senior project officer Chua Hoi-wai said the report had neglected areas such as health care for women and the elderly.
