HOSPITAL Authority efforts to overcome nursing shortages and improve services are on track, according to Dr Alison Reid, the new chief executive of the Prince of Wales Hospital. Dr Reid took up her appointment last Monday after some years managing the public hospital system in the Australian state of Tasmania. Measures like those being tried by the authority had worked in Tasmania, she said. Authority reforms include the allocation of money to hospitals based on the number and type of patients they treat and the easing of nurses' non-nursing duties. Dr Reid conceded nurses' workload at the Prince of Wales was far greater than nurses faced in Tasmanian hospitals, but said: ''I don't think this compromises the quality of care.''
