Legislators yesterday urged the Hospital Authority to make its salary adjustment mechanism more transparent, as the authority's annual report revealed its senior management received pay rises despite a series of medical blunders. Democrat legislator Andrew Cheng Kar-foo, a member of the Legislative Council's health services panel, criticised the authority for being too generous to senior managers. 'The authority spends a lot on salaries for senior management, but little on purchasing medications for patients and pay rises for frontline medical staff,' he said, calling for more supervision of senior executive pay. The Democratic Party said consultant doctors and other frontline medical staff received pay rises of between 0.3 and 4.7 per cent, while the authority's senior management was given pay rises of 3.6 to 7.6 per cent. Last night the Hospital Authority said pay adjustments had been in line with civil servants' pay rises. For staff members and senior executives, the average increases had been 4.96 per cent and 4.62 per cent in 2007-08. The authority's chief executive, Shane Solomon, received a pay rise of 3.6 per cent, taking his pay to HK$4.25 million in 2007-08. Director of cluster services Cheung Wai-lun received a pay rise of 7.6 per cent, taking his salary to HK$3.67 million. Three other executives had rises of 4.9 to 5.3 per cent. Emily Lau Wai-hing, a democrat who chairs Legco's Finance Committee, also called on the authority to increase transparency.
