The likelihood of the '360-degree' assessment scheme being implemented by the Hospital Authority is in doubt after the resignation of its key proponent, chairman Leong Che-hung. An authority spokesman said the staff-appraisal system was currently under review. 'Any proposals, if formulated, will be discussed at the Hospital Authority board and also communicated with staff group representatives through the established channels. At present, there is no concrete proposal for the review,' the spokesman said. During an interview with the South China Morning Post in February, Dr Leong revealed his plan to have the performance of the authority's senior executives, including chief executive William Ho Shiu-wei and other directors, assessed by their colleagues and staff. This followed heavy criticism of the authority's bonus scheme, which is said to be based on performance. The chief executive and the 30 hospital chief executives are all eligible for annual bonuses. They received $12.6 million in 2002-03. Dr Leong, who resigned last month, will leave the authority once a successor is found.
