DEMAND for beds in public hospitals and the most efficient way to make use of them are to be studied. Chief Executive Tung Chee-hwa said links between hospitals would also be strengthened to meet productivity enhancement targets. 'While injecting resources for development, the Government is also responsible for the optimum use of resources in the most cost-effective way to meet the needs of the people,' he said at the opening of the North District Hospital in Fanling. Mr Tung applauded the Hospital Authority for upgrading services. Noting that an enhanced productivity programme would be launched in the public sector in the next six weeks, Mr Tung hoped productivity gains amounting to five per cent of operating expenditure by 2002 would be made. 'All savings made by government departments and subsidised agencies will be used for the development of new services and improvement of our existing services,' he said. The authority's estimated expenditure for the current financial year amounts to $2.6 billion, accounting for 13 per cent of the overall recurrent public expenditure. Along with the continued improvement of essential facilities in public hospitals, Mr Tung said the Government would try to ensure health care workers were all trained to the highest level.
